The assembler has already done some of this: If the - value stored in the instruction has its 15th bit set, (counting - from zero) then the assembler will have added 1 to the value - stored in the associated HI16S reloc. So for example, these - relocations: - - movhi hi( fred ), r0, r1 - movea lo( fred ), r1, r1 - - will store 0 in the value fields for the MOVHI and MOVEA instructions - and addend will be the address of fred, but for these instructions: - - movhi hi( fred + 0x123456), r0, r1 - movea lo( fred + 0x123456), r1, r1 - - the value stored in the MOVHI instruction will be 0x12 and the value - stored in the MOVEA instruction will be 0x3456. If however the - instructions were: - - movhi hi( fred + 0x10ffff), r0, r1 - movea lo( fred + 0x10ffff), r1, r1 - - then the value stored in the MOVHI instruction would be 0x11 (not - 0x10) and the value stored in the MOVEA instruction would be 0xffff. - Thus (assuming for the moment that the addend is 0), at run time the - MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction - adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if - the instructions were: - - movhi hi( fred - 1), r0, r1 - movea lo( fred - 1), r1, r1 - - then 0 is stored in the MOVHI instruction and -1 is stored in the - MOVEA instruction. - - Overflow can occur if the addition of the value stored in the - instruction plus the addend sets the 15th bit when before it was clear. - This is because the 15th bit will be sign extended into the high part, - thus reducing its value by one, but since the 15th bit was originally - clear, the assembler will not have added 1 to the previous HI16S reloc - to compensate for this effect. For example: - - movhi hi( fred + 0x123456), r0, r1 - movea lo( fred + 0x123456), r1, r1 - - The value stored in HI16S reloc is 0x12, the value stored in the LO16 - reloc is 0x3456. If we assume that the address of fred is 0x00007000 - then the relocations become: - - HI16S: 0x0012 + (0x00007000 >> 16) = 0x12 - LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456 - - but when the instructions are executed, the MOVEA instruction's value - is signed extended, so the sum becomes: - - 0x00120000 - + 0xffffa456 - ------------ - 0x0011a456 but 'fred + 0x123456' = 0x0012a456 - - Note that if the 15th bit was set in the value stored in the LO16 - reloc, then we do not have to do anything: - - movhi hi( fred + 0x10ffff), r0, r1 - movea lo( fred + 0x10ffff), r1, r1 - - HI16S: 0x0011 + (0x00007000 >> 16) = 0x11 - LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff - - 0x00110000 - + 0x00006fff - ------------ - 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff - - Overflow can also occur if the computation carries into the 16th bit - and it also results in the 15th bit having the same value as the 15th - bit of the original value. What happens is that the HI16S reloc - will have already examined the 15th bit of the original value and - added 1 to the high part if the bit is set. This compensates for the - sign extension of 15th bit of the result of the computation. But now - there is a carry into the 16th bit, and this has not been allowed for. - - So, for example if fred is at address 0xf000: - - movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set] - movea lo( fred + 0xffff), r1, r1 - - HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001 - LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost) - - 0x00010000 - + 0xffffefff - ------------ - 0x0000efff but 'fred + 0xffff' = 0x0001efff - - Similarly, if the 15th bit remains clear, but overflow occurs into - the 16th bit then (assuming the address of fred is 0xf000): - - movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear] - movea lo( fred + 0x7000), r1, r1 - - HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000 - LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost) - - 0x00000000 - + 0x00006fff - ------------ - 0x00006fff but 'fred + 0x7000' = 0x00016fff - - Note - there is no need to change anything if a carry occurs, and the - 15th bit changes its value from being set to being clear, as the HI16S - reloc will have already added in 1 to the high part for us: - - movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set] - movea lo( fred + 0xffff), r1, r1 - - HI16S: 0x0001 + (0x00007000 >> 16) - LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost) - - 0x00010000 - + 0x00006fff (bit 15 not set, so the top half is zero) - ------------ - 0x00016fff which is right (assuming that fred is at 0x7000) - - but if the 15th bit goes from being clear to being set, then we must - once again handle overflow: - - movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear] - movea lo( fred + 0x7000), r1, r1 - - HI16S: 0x0000 + (0x0000ffff >> 16) - LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16) - - 0x00000000 - + 0x00006fff (bit 15 not set, so the top half is zero) - ------------ - 0x00006fff which is wrong (assuming that fred is at 0xffff). */ - { - long result; - - insn = bfd_get_16 (abfd, address); - result = insn + addend; - -#define BIT15_SET(x) ((x) & 0x8000) -#define OVERFLOWS(a,i) ((((a) & 0xffff) + (i)) > 0xffff) - - if ((BIT15_SET (result) && !

If you find one, then for God sakes - document it here!) - - The Microsoft docs use the word "image" instead of "executable" because - the former can also refer to a DLL (shared library). Confusion can arise - because the `i' in `pei' also refers to "image". The `pe' format can - also create images (i.e. executables), it's just that to run on a win32 - system you need to use the pei format. - - FIXME: Please add more docs here so the next poor fool that has to hack - on this code has a chance of getting something accomplished without - wasting too much time. -*/ - -#include "libpei.h" - -static boolean (*pe_saved_coff_bfd_print_private_bfd_data) - PARAMS ((bfd *, PTR)) = -#ifndef coff_bfd_print_private_bfd_data - NULL;

The file name and line -number for each address is printed on a separate line.

That license is described in the -sources for this manual page, but it is not displayed here in order to -make this manual more consise.

PREAMBLE -\" .PP -\" The purpose of this License is to make a manual, textbook, or other -\" written document "free" in the sense of freedom: to assure everyone -\" the effective freedom to copy and redistribute it, with or without -\" modifying it, either commercially or noncommercially. Secondarily, -\" this License preserves for the author and publisher a way to get -\" credit for their work, while not being considered responsible for -\" modifications made by others. -\" .PP -\" This License is a kind of "copyleft", which means that derivative -\" works of the document must themselves be free in the same sense. It -\" complements the GNU General Public License, which is a copyleft -\" license designed for free software. -\" .PP -\" We have designed this License in order to use it for manuals for free -\" software, because free software needs free documentation: a free -\" program should come with manuals providing the same freedoms that the -\" software does. But this License is not limited to software manuals; -\" it can be used for any textual work, regardless of subject matter or -\" whether it is published as a printed book. We recommend this License -\" principally for works whose purpose is instruction or reference. -\" .PP -\" 1. APPLICABILITY AND DEFINITIONS -\" .PP -\" This License applies to any manual or other work that contains a -\" notice placed by the copyright holder saying it can be distributed -\" under the terms of this License. The "Document", below, refers to any -\" such manual or work. Any member of the public is a licensee, and is -\" addressed as "you". -\" .PP -\" A "Modified Version" of the Document means any work containing the -\" Document or a portion of it, either copied verbatim, or with -\" modifications and/or translated into another language. -\" .PP -\" A "Secondary Section" is a named appendix or a front-matter section of -\" the Document that deals exclusively with the relationship of the -\" publishers or authors of the Document to the Document's overall subject -\" (or to related matters) and contains nothing that could fall directly -\" within that overall subject. (For example, if the Document is in part a -\" textbook of mathematics, a Secondary Section may not explain any -\" mathematics.) The relationship could be a matter of historical -\" connection with the subject or with related matters, or of legal, -\" commercial, philosophical, ethical or political position regarding -\" them. -\" .PP -\" The "Invariant Sections" are certain Secondary Sections whose titles -\" are designated, as being those of Invariant Sections, in the notice -\" that says that the Document is released under this License. -\" .PP -\" The "Cover Texts" are certain short passages of text that are listed, -\" as Front-Cover Texts or Back-Cover Texts, in the notice that says that -\" the Document is released under this License. -\" .PP -\" A "Transparent" copy of the Document means a machine-readable copy, -\" represented in a format whose specification is available to the -\" general public, whose contents can be viewed and edited directly and -\" straightforwardly with generic text editors or (for images composed of -\" pixels) generic paint programs or (for drawings) some widely available -\" drawing editor, and that is suitable for input to text formatters or -\" for automatic translation to a variety of formats suitable for input -\" to text formatters. A copy made in an otherwise Transparent file -\" format whose markup has been designed to thwart or discourage -\" subsequent modification by readers is not Transparent. A copy that is -\" not "Transparent" is called "Opaque". -\" .PP -\" Examples of suitable formats for Transparent copies include plain -\" ASCII without markup, Texinfo input format, LaTeX input format, SGML -\" or XML using a publicly available DTD, and standard-conforming simple -\" HTML designed for human modification. Opaque formats include -\" PostScript, PDF, proprietary formats that can be read and edited only -\" by proprietary word processors, SGML or XML for which the DTD and/or -\" processing tools are not generally available, and the -\" machine-generated HTML produced by some word processors for output -\" purposes only. -\" .PP -\" The "Title Page" means, for a printed book, the title page itself, -\" plus such following pages as are needed to hold, legibly, the material -\" this License requires to appear in the title page. For works in -\" formats which do not have any title page as such, "Title Page" means -\" the text near the most prominent appearance of the work's title, -\" preceding the beginning of the body of the text. -\" .PP -\" 2. VERBATIM COPYING -\" .PP -\" You may copy and distribute the Document in any medium, either -\" commercially or noncommercially, provided that this License, the -\" copyright notices, and the license notice saying this License applies -\" to the Document are reproduced in all copies, and that you add no other -\" conditions whatsoever to those of this License. You may not use -\" technical measures to obstruct or control the reading or further -\" copying of the copies you make or distribute. However, you may accept -\" compensation in exchange for copies. If you distribute a large enough -\" number of copies you must also follow the conditions in section 3. -\" .PP -\" You may also lend copies, under the same conditions stated above, and -\" you may publicly display copies. -\" .PP -\" 3. COPYING IN QUANTITY -\" .PP -\" If you publish printed copies of the Document numbering more than 100, -\" and the Document's license notice requires Cover Texts, you must enclose -\" the copies in covers that carry, clearly and legibly, all these Cover -\" Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -\" the back cover. Both covers must also clearly and legibly identify -\" you as the publisher of these copies. The front cover must present -\" the full title with all words of the title equally prominent and -\" visible. You may add other material on the covers in addition. -\" Copying with changes limited to the covers, as long as they preserve -\" the title of the Document and satisfy these conditions, can be treated -\" as verbatim copying in other respects. -\" .PP -\" If the required texts for either cover are too voluminous to fit -\" legibly, you should put the first ones listed (as many as fit -\" reasonably) on the actual cover, and continue the rest onto adjacent -\" pages. -\" .PP -\" If you publish or distribute Opaque copies of the Document numbering -\" more than 100, you must either include a machine-readable Transparent -\" copy along with each Opaque copy, or state in or with each Opaque copy -\" a publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. If you use the latter -\" option, you must take reasonably prudent steps, when you begin -\" distribution of Opaque copies in quantity, to ensure that this -\" Transparent copy will remain thus accessible at the stated location -\" until at least one year after the last time you distribute an Opaque -\" copy (directly or through your agents or retailers) of that edition to -\" the public. -\" .PP -\" It is requested, but not required, that you contact the authors of the -\" Document well before redistributing any large number of copies, to give -\" them a chance to provide you with an updated version of the Document. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" You may copy and distribute a Modified Version of the Document under -\" the conditions of sections 2 and 3 above, provided that you release -\" the Modified Version under precisely this License, with the Modified -\" Version filling the role of the Document, thus licensing distribution -\" and modification of the Modified Version to whoever possesses a copy -\" of it. In addition, you must do these things in the Modified Version: -\" .PP -\" A. Use in the Title Page (and on the covers, if any) a title distinct -\" from that of the Document, and from those of previous versions -\" (which should, if there were any, be listed in the History section -\" of the Document). You may use the same title as a previous version -\" if the original publisher of that version gives permission. -\" .PP -\" B. List on the Title Page, as authors, one or more persons or entities -\" responsible for authorship of the modifications in the Modified -\" Version, together with at least five of the principal authors of the -\" Document (all of its principal authors, if it has less than five). -\" .PP -\" C. State on the Title page the name of the publisher of the -\" Modified Version, as the publisher. -\" .PP -\" D. Preserve all the copyright notices of the Document. -\" .PP -\" E. Add an appropriate copyright notice for your modifications -\" adjacent to the other copyright notices. -\" .PP -\" F. Include, immediately after the copyright notices, a license notice -\" giving the public permission to use the Modified Version under the -\" terms of this License, in the form shown in the Addendum below. -\" Preserve in that license notice the full lists of Invariant Sections -\" and required Cover Texts given in the Document's license notice. -\" .PP -\" H. Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and its title, and add to -\" it an item stating at least the title, year, new authors, and -\" publisher of the Modified Version as given on the Title Page. If -\" there is no section entitled "History" in the Document, create one -\" stating the title, year, authors, and publisher of the Document as -\" given on its Title Page, then add an item describing the Modified -\" Version as stated in the previous sentence. -\" .PP -\" J. Preserve the network location, if any, given in the Document for -\" public access to a Transparent copy of the Document, and likewise -\" the network locations given in the Document for previous versions -\" it was based on. These may be placed in the "History" section. -\" You may omit a network location for a work that was published at -\" least four years before the Document itself, or if the original -\" publisher of the version it refers to gives permission. -\" .PP -\" K. In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" L. Preserve all the Invariant Sections of the Document, -\" unaltered in their text and in their titles. Section numbers -\" or the equivalent are not considered part of the section titles. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" If the Modified Version includes new front-matter sections or -\" appendices that qualify as Secondary Sections and contain no material -\" copied from the Document, you may at your option designate some or all -\" of these sections as invariant. To do this, add their titles to the -\" list of Invariant Sections in the Modified Version's license notice. -\" These titles must be distinct from any other section titles. -\" .PP -\" You may add a section entitled "Endorsements", provided it contains -\" nothing but endorsements of your Modified Version by various -\" parties--for example, statements of peer review or that the text has -\" been approved by an organization as the authoritative definition of a -\" standard. -\" .PP -\" You may add a passage of up to five words as a Front-Cover Text, and a -\" passage of up to 25 words as a Back-Cover Text, to the end of the list -\" of Cover Texts in the Modified Version. Only one passage of -\" Front-Cover Text and one of Back-Cover Text may be added by (or -\" through arrangements made by) any one entity. If the Document already -\" includes a cover text for the same cover, previously added by you or -\" by arrangement made by the same entity you are acting on behalf of, -\" you may not add another; but you may replace the old one, on explicit -\" permission from the previous publisher that added the old one. -\" .PP -\" The author(s) and publisher(s) of the Document do not by this License -\" give permission to use their names for publicity for or to assert or -\" imply endorsement of any Modified Version. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" You may combine the Document with other documents released under this -\" License, under the terms defined in section 4 above for modified -\" versions, provided that you include in the combination all of the -\" Invariant Sections of all of the original documents, unmodified, and -\" list them all as Invariant Sections of your combined work in its -\" license notice. -\" .PP -\" The combined work need only contain one copy of this License, and -\" multiple identical Invariant Sections may be replaced with a single -\" copy. If there are multiple Invariant Sections with the same name but -\" different contents, make the title of each such section unique by -\" adding at the end of it, in parentheses, the name of the original -\" author or publisher of that section if known, or else a unique number. -\" Make the same adjustment to the section titles in the list of -\" Invariant Sections in the license notice of the combined work. -\" .PP -\" In the combination, you must combine any sections entitled "History" -\" in the various original documents, forming one section entitled -\" "History"; likewise combine any sections entitled "Acknowledgements", -\" and any sections entitled "Dedications". You must delete all sections -\" entitled "Endorsements." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License. Any other attempt to -\" copy, modify, sublicense or distribute the Document is void, and will -\" automatically terminate your rights under this License. However, -\" parties who have received copies, or rights, from you under this -\" License will not have their licenses terminated so long as such -\" parties remain in full compliance. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time.

An \c -.I archive\c -\& is a single file holding a collection of -other files in a structure that makes it possible to retrieve -the original individual files (called \c -.I members\c -\& of the archive). - -The original files' contents, mode (permissions), timestamp, owner, and -group are preserved in the archive, and may be reconstituted on -extraction. - -GNU \c -.B ar\c -\& can maintain archives whose members have names of any -length; however, depending on how \c -.B ar\c -\& is configured on your -system, a limit on member-name length may be imposed (for compatibility -with archive formats maintained with other tools). If it exists, the -limit is often 15 characters (typical of formats related to a.out) or 16 -characters (typical of formats related to coff). - -\c -.B ar\c -\& is considered a binary utility because archives of this sort -are most often used as \c -.I libraries\c -\& holding commonly needed -subroutines. - -\c -.B ar\c -\& will create an index to the symbols defined in relocatable -object modules in the archive when you specify the modifier `\|\c -.B s\c -\|'. -Once created, this index is updated in the archive whenever \c -.B ar\c -\& -makes a change to its contents (save for the `\|\c -.B q\c -\|' update operation). -An archive with such an index speeds up linking to the library, and -allows routines in the library to call each other without regard to -their placement in the archive. - -You may use `\|\c -.B nm \-s\c -\|' or `\|\c -.B nm \-\-print\-armap\c -\|' to list this index -table. If an archive lacks the table, another form of \c -.B ar\c -\& called -\c -.B ranlib\c -\& can be used to add just the table. - -\c -.B ar\c -\& insists on at least two arguments to execute: one -keyletter specifying the \c -.I operation\c -\& (optionally accompanied by other -keyletters specifying \c -.I modifiers\c -\&), and the archive name to act on. - -Most operations can also accept further \c -.I files\c -\& arguments, -specifying particular files to operate on. - -.SH OPTIONS -GNU \c -.B ar\c -\& allows you to mix the operation code \c -.I p\c -\& and modifier -flags \c -.I mod\c -\& in any order, within the first command-line argument. - -If you wish, you may begin the first command-line argument with a -dash. - -The \c -.I p\c -\& keyletter specifies what operation to execute; it may be -any of the following, but you must specify only one of them: - -.TP -.B d -\c -.I Delete\c -\& modules from the archive. Specify the names of modules to -be deleted as \c -.I files\c -\&; the archive is untouched if you -specify no files to delete. - -If you specify the `\|\c -.B v\c -\|' modifier, \c -.B ar\c -\& will list each module -as it is deleted. - -.TP -.B m -Use this operation to \c -.I move\c -\& members in an archive. - -The ordering of members in an archive can make a difference in how -programs are linked using the library, if a symbol is defined in more -than one member. - -If no modifiers are used with \c -.B m\c -\&, any members you name in the -\c -.I files\c -\& arguments are moved to the \c -.I end\c -\& of the archive; -you can use the `\|\c -.B a\c -\|', `\|\c -.B b\c -\|', or `\|\c -.B i\c -\|' modifiers to move them to a -specified place instead. - -.TP -.B p -\c -.I Print\c -\& the specified members of the archive, to the standard -output file. If the `\|\c -.B v\c -\|' modifier is specified, show the member -name before copying its contents to standard output. - -If you specify no \c -.I files\c -\&, all the files in the archive are printed. - -.TP -.B q -\c -.I Quick append\c -\&; add \c -.I files\c -\& to the end of \c -.I archive\c -\&, -without checking for replacement. - -The modifiers `\|\c -.B a\c -\|', `\|\c -.B b\c -\|', and `\|\c -.B i\c -\|' do \c -.I not\c -\& affect this -operation; new members are always placed at the end of the archive. - -The modifier `\|\c -.B v\c -\|' makes \c -.B ar\c -\& list each file as it is appended. - -Since the point of this operation is speed, the archive's symbol table -index is not updated, even if it already existed; you can use `\|\c -.B ar s\c -\|' or -\c -.B ranlib\c -\& explicitly to update the symbol table index. - -However, too many different systems assume quick append rebuilds the -index, so GNU -.B ar -implements `\|\c -.B q\c -\|' as a synonym for `\|\c -.B r\c -\|'. - -.TP -.B r -Insert \c -.I files\c -\& into \c -.I archive\c -\& (with \c -.I replacement\c -\&). This -operation differs from `\|\c -.B q\c -\|' in that any previously existing members -are deleted if their names match those being added. - -If one of the files named in \c -.I files\c -\& doesn't exist, \c -.B ar\c -\& -displays an error message, and leaves undisturbed any existing members -of the archive matching that name. - -By default, new members are added at the end of the file; but you may -use one of the modifiers `\|\c -.B a\c -\|', `\|\c -.B b\c -\|', or `\|\c -.B i\c -\|' to request -placement relative to some existing member. - -The modifier `\|\c -.B v\c -\|' used with this operation elicits a line of -output for each file inserted, along with one of the letters `\|\c -.B a\c -\|' or -`\|\c -.B r\c -\|' to indicate whether the file was appended (no old member -deleted) or replaced. - -.TP -.B t -Display a \c -.I table\c -\& listing the contents of \c -.I archive\c -\&, or those -of the files listed in \c -.I files\c -\& that are present in the -archive. Normally only the member name is shown; if you also want to -see the modes (permissions), timestamp, owner, group, and size, you can -request that by also specifying the `\|\c -.B v\c -\|' modifier. - -If you do not specify any \c -.I files\c -\&, all files in the archive -are listed. - -If there is more than one file with the same name (say, `\|\c -.B fie\c -\|') in -an archive (say `\|\c -.B b.a\c -\|'), `\|\c -.B ar t b.a fie\c -\|' will list only the -first instance; to see them all, you must ask for a complete -listing\(em\&in our example, `\|\c -.B ar t b.a\c -\|'. - -.TP -.B x -\c -.I Extract\c -\& members (named \c -.I files\c -\&) from the archive. You can -use the `\|\c -.B v\c -\|' modifier with this operation, to request that -\c -.B ar\c -\& list each name as it extracts it. - -If you do not specify any \c -.I files\c -\&, all files in the archive -are extracted. - -.PP - -A number of modifiers (\c -.I mod\c -\&) may immediately follow the \c -.I p\c -\& -keyletter, to specify variations on an operation's behavior: - -.TP -.B a -Add new files \c -.I after\c -\& an existing member of the -archive. If you use the modifier \c -.B a\c -\&, the name of an existing archive -member must be present as the \c -.I membername\c -\& argument, before the -\c -.I archive\c -\& specification. - -.TP -.B b -Add new files \c -.I before\c -\& an existing member of the -archive. If you use the modifier \c -.B b\c -\&, the name of an existing archive -member must be present as the \c -.I membername\c -\& argument, before the -\c -.I archive\c -\& specification. (same as `\|\c -.B i\c -\|'). - -.TP -.B c -\c -.I Create\c -\& the archive. The specified \c -.I archive\c -\& is always -created if it didn't exist, when you request an update. But a warning is -issued unless you specify in advance that you expect to create it, by -using this modifier. - -.TP -.B f -Truncate names in the archive. -.B ar -will normally permit file names of any length. This will cause it to -create archives which are not compatible with the native -.B ar -program on some systems. If this is a concern, the -.B f -modifier may be used to truncate file names when putting them in the -archive. - -.TP -.B i -Insert new files \c -.I before\c -\& an existing member of the -archive. If you use the modifier \c -.B i\c -\&, the name of an existing archive -member must be present as the \c -.I membername\c -\& argument, before the -\c -.I archive\c -\& specification. (same as `\|\c -.B b\c -\|'). - -.TP -.B l -This modifier is accepted but not used. - -.TP -.B N -Uses the -.I count -parameter. This is used if there are multiple entries in the archive -with the same name. Extract or delete instance -.I count -of the given name from the archive. - -.TP -.B o -Preserve the \c -.I original\c -\& dates of members when extracting them. If -you do not specify this modifier, files extracted from the archive -will be stamped with the time of extraction. - -.TP -.B P -Use the full path name when matching names in the archive. -.B ar -can not create an archive with a full path name (such archives are not -POSIX complaint), but other archive creators can. This option will -cause -.B ar -to match file names using a complete path name, which can be -convenient when extracting a single file from an archive created by -another tool. - -.TP -.B s -Write an object-file index into the archive, or update an existing one, -even if no other change is made to the archive. You may use this modifier -flag either with any operation, or alone. Running `\|\c -.B ar s\c -\|' on an -archive is equivalent to running `\|\c -.B ranlib\c -\|' on it. - -.TP -.B S -Do not generate an archive symbol table. This can speed up building a -large library in several steps. The resulting archive can not be used -with the linker. In order to build a symbol table, you must omit the -`\|\c -.B S\c -\|' modifier on the last execution of `\|\c -.B ar\c -\|', or you must run `\|\c -.B ranlib\c -\|' on the archive. - -.TP -.B u -Normally, \c -.B ar r\c -\&.\|.\|. inserts all files -listed into the archive. If you would like to insert \c -.I only\c -\& those -of the files you list that are newer than existing members of the same -names, use this modifier. The `\|\c -.B u\c -\|' modifier is allowed only for the -operation `\|\c -.B r\c -\|' (replace). In particular, the combination `\|\c -.B qu\c -\|' is -not allowed, since checking the timestamps would lose any speed -advantage from the operation `\|\c -.B q\c -\|'. - -.TP -.B v -This modifier requests the \c -.I verbose\c -\& version of an operation. Many -operations display additional information, such as filenames processed, -when the modifier `\|\c -.B v\c -\|' is appended. - -.TP -.B V -This modifier shows the version number of -.BR ar . - -.PP - -.SH "SEE ALSO" -.RB "`\|" binutils "\|'" -entry in -.B -info\c -\&; -.I -The GNU Binary Utilities\c -, Roland H.

Opaque formats include -\" PostScript, PDF, proprietary formats that can be read and edited only -\" by proprietary word processors, SGML or XML for which the DTD and/or -\" processing tools are not generally available, and the -\" machine-generated HTML produced by some word processors for output -\" purposes only. -\" .PP -\" The "Title Page" means, for a printed book, the title page itself, -\" plus such following pages as are needed to hold, legibly, the material -\" this License requires to appear in the title page. For works in -\" formats which do not have any title page as such, "Title Page" means -\" the text near the most prominent appearance of the work's title, -\" preceding the beginning of the body of the text. -\" .PP -\" 2.

AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License.

An @dfn{archive} is a single file holding a collection of -other files in a structure that makes it possible to retrieve -the original individual files (called @dfn{members} of the archive). - -The original files' contents, mode (permissions), timestamp, owner, and -group are preserved in the archive, and can be restored on -extraction. - -@cindex name length -@sc{gnu} @code{ar} can maintain archives whose members have names of any -length; however, depending on how @code{ar} is configured on your -system, a limit on member-name length may be imposed for compatibility -with archive formats maintained with other tools. If it exists, the -limit is often 15 characters (typical of formats related to a.out) or 16 -characters (typical of formats related to coff). - -@cindex libraries -@code{ar} is considered a binary utility because archives of this sort -are most often used as @dfn{libraries} holding commonly needed -subroutines. - -@cindex symbol index -@code{ar} creates an index to the symbols defined in relocatable -object modules in the archive when you specify the modifier @samp{s}. -Once created, this index is updated in the archive whenever @code{ar} -makes a change to its contents (save for the @samp{q} update operation). -An archive with such an index speeds up linking to the library, and -allows routines in the library to call each other without regard to -their placement in the archive. - -You may use @samp{nm -s} or @samp{nm --print-armap} to list this index -table. If an archive lacks the table, another form of @code{ar} called -@code{ranlib} can be used to add just the table. - -@cindex compatibility, @code{ar} -@cindex @code{ar} compatibility -@sc{gnu} @code{ar} is designed to be compatible with two different -facilities. You can control its activity using command-line options, -like the different varieties of @code{ar} on Unix systems; or, if you -specify the single command-line option @samp{-M}, you can control it -with a script supplied via standard input, like the MRI ``librarian'' -program. - -@menu -* ar cmdline:: Controlling @code{ar} on the command line -* ar scripts:: Controlling @code{ar} with a script -@end menu - -@page -@node ar cmdline -@section Controlling @code{ar} on the command line - -@smallexample -ar [-X32_64] [-]@var{p}[@var{mod} [@var{relpos}] [@var{count}]] @var{archive} [@var{member}@dots{}] -@end smallexample - -@cindex Unix compatibility, @code{ar} -When you use @code{ar} in the Unix style, @code{ar} insists on at least two -arguments to execute: one keyletter specifying the @emph{operation} -(optionally accompanied by other keyletters specifying -@emph{modifiers}), and the archive name to act on. - -Most operations can also accept further @var{member} arguments, -specifying particular files to operate on. - -@sc{gnu} @code{ar} allows you to mix the operation code @var{p} and modifier -flags @var{mod} in any order, within the first command-line argument. - -If you wish, you may begin the first command-line argument with a -dash. - -@cindex operations on archive -The @var{p} keyletter specifies what operation to execute; it may be -any of the following, but you must specify only one of them: - -@table @code -@item d -@cindex deleting from archive -@emph{Delete} modules from the archive. Specify the names of modules to -be deleted as @var{member}@dots{}; the archive is untouched if you -specify no files to delete. - -If you specify the @samp{v} modifier, @code{ar} lists each module -as it is deleted. - -@item m -@cindex moving in archive -Use this operation to @emph{move} members in an archive. - -The ordering of members in an archive can make a difference in how -programs are linked using the library, if a symbol is defined in more -than one member. - -If no modifiers are used with @code{m}, any members you name in the -@var{member} arguments are moved to the @emph{end} of the archive; -you can use the @samp{a}, @samp{b}, or @samp{i} modifiers to move them to a -specified place instead. - -@item p -@cindex printing from archive -@emph{Print} the specified members of the archive, to the standard -output file. If the @samp{v} modifier is specified, show the member -name before copying its contents to standard output. - -If you specify no @var{member} arguments, all the files in the archive are -printed. - -@item q -@cindex quick append to archive -@emph{Quick append}; Historically, add the files @var{member}@dots{} to the end of -@var{archive}, without checking for replacement. - -The modifiers @samp{a}, @samp{b}, and @samp{i} do @emph{not} affect this -operation; new members are always placed at the end of the archive. - -The modifier @samp{v} makes @code{ar} list each file as it is appended. - -Since the point of this operation is speed, the archive's symbol table -index is not updated, even if it already existed; you can use @samp{ar s} or -@code{ranlib} explicitly to update the symbol table index. - -However, too many different systems assume quick append rebuilds the -index, so GNU ar implements @code{q} as a synonym for @code{r}. - -@item r -@cindex replacement in archive -Insert the files @var{member}@dots{} into @var{archive} (with -@emph{replacement}). This operation differs from @samp{q} in that any -previously existing members are deleted if their names match those being -added. - -If one of the files named in @var{member}@dots{} does not exist, @code{ar} -displays an error message, and leaves undisturbed any existing members -of the archive matching that name. - -By default, new members are added at the end of the file; but you may -use one of the modifiers @samp{a}, @samp{b}, or @samp{i} to request -placement relative to some existing member. - -The modifier @samp{v} used with this operation elicits a line of -output for each file inserted, along with one of the letters @samp{a} or -@samp{r} to indicate whether the file was appended (no old member -deleted) or replaced. - -@item t -@cindex contents of archive -Display a @emph{table} listing the contents of @var{archive}, or those -of the files listed in @var{member}@dots{} that are present in the -archive. Normally only the member name is shown; if you also want to -see the modes (permissions), timestamp, owner, group, and size, you can -request that by also specifying the @samp{v} modifier. - -If you do not specify a @var{member}, all files in the archive -are listed. - -@cindex repeated names in archive -@cindex name duplication in archive -If there is more than one file with the same name (say, @samp{fie}) in -an archive (say @samp{b.a}), @samp{ar t b.a fie} lists only the -first instance; to see them all, you must ask for a complete -listing---in our example, @samp{ar t b.a}. -@c WRS only; per Gumby, this is implementation-dependent, and in a more -@c recent case in fact works the other way. - -@item x -@cindex extract from archive -@emph{Extract} members (named @var{member}) from the archive. You can -use the @samp{v} modifier with this operation, to request that -@code{ar} list each name as it extracts it. - -If you do not specify a @var{member}, all files in the archive -are extracted. - -@end table - -A number of modifiers (@var{mod}) may immediately follow the @var{p} -keyletter, to specify variations on an operation's behavior: - -@table @code -@item a -@cindex relative placement in archive -Add new files @emph{after} an existing member of the -archive. If you use the modifier @samp{a}, the name of an existing archive -member must be present as the @var{relpos} argument, before the -@var{archive} specification. - -@item b -Add new files @emph{before} an existing member of the -archive. If you use the modifier @samp{b}, the name of an existing archive -member must be present as the @var{relpos} argument, before the -@var{archive} specification. (same as @samp{i}). - -@item c -@cindex creating archives -@emph{Create} the archive. The specified @var{archive} is always -created if it did not exist, when you request an update. But a warning is -issued unless you specify in advance that you expect to create it, by -using this modifier. - -@item f -Truncate names in the archive. @sc{gnu} @code{ar} will normally permit file -names of any length. This will cause it to create archives which are -not compatible with the native @code{ar} program on some systems. If -this is a concern, the @samp{f} modifier may be used to truncate file -names when putting them in the archive. - -@item i -Insert new files @emph{before} an existing member of the -archive. If you use the modifier @samp{i}, the name of an existing archive -member must be present as the @var{relpos} argument, before the -@var{archive} specification. (same as @samp{b}). - -@item l -This modifier is accepted but not used. -@c whaffor ar l modifier??? presumably compat; with -@c what???---doc@@cygnus.com, 25jan91 - -@item N -Uses the @var{count} parameter. This is used if there are multiple -entries in the archive with the same name. Extract or delete instance -@var{count} of the given name from the archive. - -@item o -@cindex dates in archive -Preserve the @emph{original} dates of members when extracting them. If -you do not specify this modifier, files extracted from the archive -are stamped with the time of extraction. - -@item P -Use the full path name when matching names in the archive. @sc{gnu} -@code{ar} can not create an archive with a full path name (such archives -are not POSIX complaint), but other archive creators can. This option -will cause @sc{gnu} @code{ar} to match file names using a complete path -name, which can be convenient when extracting a single file from an -archive created by another tool. - -@item s -@cindex writing archive index -Write an object-file index into the archive, or update an existing one, -even if no other change is made to the archive. You may use this modifier -flag either with any operation, or alone. Running @samp{ar s} on an -archive is equivalent to running @samp{ranlib} on it. - -@item S -@cindex not writing archive index -Do not generate an archive symbol table. This can speed up building a -large library in several steps. The resulting archive can not be used -with the linker. In order to build a symbol table, you must omit the -@samp{S} modifier on the last execution of @samp{ar}, or you must run -@samp{ranlib} on the archive. - -@item u -@cindex updating an archive -Normally, @samp{ar r}@dots{} inserts all files -listed into the archive. If you would like to insert @emph{only} those -of the files you list that are newer than existing members of the same -names, use this modifier. The @samp{u} modifier is allowed only for the -operation @samp{r} (replace). In particular, the combination @samp{qu} is -not allowed, since checking the timestamps would lose any speed -advantage from the operation @samp{q}. - -@item v -This modifier requests the @emph{verbose} version of an operation. Many -operations display additional information, such as filenames processed, -when the modifier @samp{v} is appended. - -@item V -This modifier shows the version number of @code{ar}. -@end table - -@code{ar} ignores an initial option spelt @code{-X32_64}, for -compatibility with AIX. The behaviour produced by this option is the -default for GNU @code{ar}. @code{ar} does not support any of the other -@code{-X} options; in particular, it does not support @code{-X32} -which is the default for AIX @code{ar}. - -@node ar scripts -@section Controlling @code{ar} with a script - -@smallexample -ar -M [ <@var{script} ] -@end smallexample - -@cindex MRI compatibility, @code{ar} -@cindex scripts, @code{ar} -If you use the single command-line option @samp{-M} with @code{ar}, you -can control its operation with a rudimentary command language. This -form of @code{ar} operates interactively if standard input is coming -directly from a terminal. During interactive use, @code{ar} prompts for -input (the prompt is @samp{AR >}), and continues executing even after -errors. If you redirect standard input to a script file, no prompts are -issued, and @code{ar} abandons execution (with a nonzero exit code) -on any error. - -The @code{ar} command language is @emph{not} designed to be equivalent -to the command-line options; in fact, it provides somewhat less control -over archives. The only purpose of the command language is to ease the -transition to @sc{gnu} @code{ar} for developers who already have scripts -written for the MRI ``librarian'' program. - -The syntax for the @code{ar} command language is straightforward: -@itemize @bullet -@item -commands are recognized in upper or lower case; for example, @code{LIST} -is the same as @code{list}. In the following descriptions, commands are -shown in upper case for clarity. - -@item -a single command may appear on each line; it is the first word on the -line. - -@item -empty lines are allowed, and have no effect. - -@item -comments are allowed; text after either of the characters @samp{*} -or @samp{;} is ignored. - -@item -Whenever you use a list of names as part of the argument to an @code{ar} -command, you can separate the individual names with either commas or -blanks. Commas are shown in the explanations below, for clarity. - -@item -@samp{+} is used as a line continuation character; if @samp{+} appears -at the end of a line, the text on the following line is considered part -of the current command. -@end itemize - -Here are the commands you can use in @code{ar} scripts, or when using -@code{ar} interactively. Three of them have special significance: - -@code{OPEN} or @code{CREATE} specify a @dfn{current archive}, which is -a temporary file required for most of the other commands. - -@code{SAVE} commits the changes so far specified by the script. Prior -to @code{SAVE}, commands affect only the temporary copy of the current -archive. - -@table @code -@item ADDLIB @var{archive} -@itemx ADDLIB @var{archive} (@var{module}, @var{module}, @dots{} @var{module}) -Add all the contents of @var{archive} (or, if specified, each named -@var{module} from @var{archive}) to the current archive. - -Requires prior use of @code{OPEN} or @code{CREATE}. - -@item ADDMOD @var{member}, @var{member}, @dots{} @var{member} -@c FIXME! w/Replacement?? If so, like "ar r @var{archive} @var{names}" -@c else like "ar q..." -Add each named @var{member} as a module in the current archive. - -Requires prior use of @code{OPEN} or @code{CREATE}. - -@item CLEAR -Discard the contents of the current archive, canceling the effect of -any operations since the last @code{SAVE}. May be executed (with no -effect) even if no current archive is specified. - -@item CREATE @var{archive} -Creates an archive, and makes it the current archive (required for many -other commands). The new archive is created with a temporary name; it -is not actually saved as @var{archive} until you use @code{SAVE}. -You can overwrite existing archives; similarly, the contents of any -existing file named @var{archive} will not be destroyed until @code{SAVE}. - -@item DELETE @var{module}, @var{module}, @dots{} @var{module} -Delete each listed @var{module} from the current archive; equivalent to -@samp{ar -d @var{archive} @var{module} @dots{} @var{module}}. - -Requires prior use of @code{OPEN} or @code{CREATE}. - -@item DIRECTORY @var{archive} (@var{module}, @dots{} @var{module}) -@itemx DIRECTORY @var{archive} (@var{module}, @dots{} @var{module}) @var{outputfile} -List each named @var{module} present in @var{archive}. The separate -command @code{VERBOSE} specifies the form of the output: when verbose -output is off, output is like that of @samp{ar -t @var{archive} -@var{module}@dots{}}. When verbose output is on, the listing is like -@samp{ar -tv @var{archive} @var{module}@dots{}}. - -Output normally goes to the standard output stream; however, if you -specify @var{outputfile} as a final argument, @code{ar} directs the -output to that file. - -@item END -Exit from @code{ar}, with a @code{0} exit code to indicate successful -completion. This command does not save the output file; if you have -changed the current archive since the last @code{SAVE} command, those -changes are lost. - -@item EXTRACT @var{module}, @var{module}, @dots{} @var{module} -Extract each named @var{module} from the current archive, writing them -into the current directory as separate files.

The effect is like @samp{ar -tv @var{archive}}. (This single command is a @sc{gnu} @code{ar} -enhancement, rather than present for MRI compatibility.) - -Requires prior use of @code{OPEN} or @code{CREATE}. - -@item OPEN @var{archive} -Opens an existing archive for use as the current archive (required for -many other commands).

This -is a text file and can be created by hand, or @code{dlltool} can be used -to create it using the @samp{-z} option. In this case @code{dlltool} -will scan the object files specified on its command line looking for -those functions which have been specially marked as being exported and -put entries for them in the .def file it creates. - -In order to mark a function as being exported from a DLL, it needs to -have an @samp{-export:<name_of_function>} entry in the @samp{.drectve} -section of the object file.

If you obtained the binary utilities from a support -organization, we recommend you contact that organization first. - -You can find contact information for many support companies and -individuals in the file @file{etc/SERVICE} in the @sc{gnu} Emacs -distribution. - -In any event, we also recommend that you send bug reports for the binary -utilities to @samp{bug-binutils@@gnu.org}. - -The fundamental principle of reporting bugs usefully is this: -@strong{report all the facts}. If you are not sure whether to state a -fact or leave it out, state it! - -Often people omit facts because they think they know what causes the -problem and assume that some details do not matter. Thus, you might -assume that the name of a file you use in an example does not matter. -Well, probably it does not, but one cannot be sure. Perhaps the bug is -a stray memory reference which happens to fetch from the location where -that pathname is stored in memory; perhaps, if the pathname were -different, the contents of that location would fool the utility into -doing the right thing despite the bug. Play it safe and give a -specific, complete example. That is the easiest thing for you to do, -and the most helpful. - -Keep in mind that the purpose of a bug report is to enable us to fix the bug if -it is new to us. Therefore, always write your bug reports on the assumption -that the bug has not been reported previously. - -Sometimes people give a few sketchy facts and ask, ``Does this ring a -bell?'' Those bug reports are useless, and we urge everyone to -@emph{refuse to respond to them} except to chide the sender to report -bugs properly. - -To enable us to fix the bug, you should include all these things: - -@itemize @bullet -@item -The version of the utility. Each utility announces it if you start it -with the @samp{--version} argument. - -Without this, we will not know whether there is any point in looking for -the bug in the current version of the binary utilities. - -@item -Any patches you may have applied to the source, including any patches -made to the @code{BFD} library. - -@item -The type of machine you are using, and the operating system name and -version number. - -@item -What compiler (and its version) was used to compile the utilities---e.g. -``@code{gcc-2.7}''. - -@item -The command arguments you gave the utility to observe the bug. To -guarantee you will not omit something important, list them all. A copy -of the Makefile (or the output from make) is sufficient. - -If we were to try to guess the arguments, we would probably guess wrong -and then we might not encounter the bug. - -@item -A complete input file, or set of input files, that will reproduce the -bug. If the utility is reading an object file or files, then it is -generally most helpful to send the actual object files, uuencoded if -necessary to get them through the mail system. Note that -@samp{bug-binutils@@gnu.org} is a mailing list, so you should avoid -sending very large files to it. Making the files available for -anonymous FTP is OK. - -If the source files were produced exclusively using @sc{gnu} programs -(e.g., @code{gcc}, @code{gas}, and/or the @sc{gnu} @code{ld}), then it -may be OK to send the source files rather than the object files. In -this case, be sure to say exactly what version of @code{gcc}, or -whatever, was used to produce the object files. Also say how -@code{gcc}, or whatever, was configured. - -@item -A description of what behavior you observe that you believe is -incorrect. For example, ``It gets a fatal signal.'' - -Of course, if the bug is that the utility gets a fatal signal, then we -will certainly notice it. But if the bug is incorrect output, we might -not notice unless it is glaringly wrong. You might as well not give us -a chance to make a mistake. - -Even if the problem you experience is a fatal signal, you should still -say so explicitly. Suppose something strange is going on, such as your -copy of the utility is out of synch, or you have encountered a bug in -the C library on your system. (This has happened!) Your copy might -crash and ours would not. If you told us to expect a crash, then when -ours fails to crash, we would know that the bug was not happening for -us. If you had not told us to expect a crash, then we would not be able -to draw any conclusion from our observations. - -@item -If you wish to suggest changes to the source, send us context diffs, as -generated by @code{diff} with the @samp{-u}, @samp{-c}, or @samp{-p} -option. Always send diffs from the old file to the new file. If you -wish to discuss something in the @code{ld} source, refer to it by -context, not by line number. - -The line numbers in our development sources will not match those in your -sources. Your line numbers would convey no useful information to us. -@end itemize - -Here are some things that are not necessary: - -@itemize @bullet -@item -A description of the envelope of the bug. - -Often people who encounter a bug spend a lot of time investigating -which changes to the input file will make the bug go away and which -changes will not affect it. - -This is often time consuming and not very useful, because the way we -will find the bug is by running a single example under the debugger -with breakpoints, not by pure deduction from a series of examples. -We recommend that you save your time for something else. - -Of course, if you can find a simpler example to report @emph{instead} -of the original one, that is a convenience for us. Errors in the -output will be easier to spot, running under the debugger will take -less time, and so on. - -However, simplification is not vital; if you do not want to do this, -report the bug anyway and send us the entire test case you used. - -@item -A patch for the bug. - -A patch for the bug does help us if it is a good one. But do not omit -the necessary information, such as the test case, on the assumption that -a patch is all we need. We might see problems with your patch and decide -to fix the problem another way, or we might not understand it at all. - -Sometimes with programs as complicated as the binary utilities it is -very hard to construct an example that will make the program follow a -certain path through the code. If you do not send us the example, we -will not be able to construct one, so we will not be able to verify that -the bug is fixed. - -And if we cannot understand what bug you are trying to fix, or why your -patch should be an improvement, we will not install it. A test case will -help us to understand. - -@item -A guess about what the bug is or what it depends on. - -Such guesses are usually wrong.

Secondarily, -this License preserves for the author and publisher a way to get -credit for their work, while not being considered responsible for -modifications made by others. - -This License is a kind of "copyleft", which means that derivative -works of the document must themselves be free in the same sense. It -complements the GNU General Public License, which is a copyleft -license designed for free software. - -We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. - - -1. APPLICABILITY AND DEFINITIONS - -This License applies to any manual or other work that contains a -notice placed by the copyright holder saying it can be distributed -under the terms of this License. The "Document", below, refers to any -such manual or work. Any member of the public is a licensee, and is -addressed as "you". - -A "Modified Version" of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A "Secondary Section" is a named appendix or a front-matter section of -the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall subject -(or to related matters) and contains nothing that could fall directly -within that overall subject. (For example, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The "Invariant Sections" are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. - -The "Cover Texts" are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. - -A "Transparent" copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, whose contents can be viewed and edited directly and -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup has been designed to thwart or discourage -subsequent modification by readers is not Transparent. A copy that is -not "Transparent" is called "Opaque". - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, LaTeX input format, SGML -or XML using a publicly available DTD, and standard-conforming simple -HTML designed for human modification. Opaque formats include -PostScript, PDF, proprietary formats that can be read and edited only -by proprietary word processors, SGML or XML for which the DTD and/or -processing tools are not generally available, and the -machine-generated HTML produced by some word processors for output -purposes only. - -The "Title Page" means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, "Title Page" means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - - -2. VERBATIM COPYING - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. - -You may also lend copies, under the same conditions stated above, and -you may publicly display copies. - - -3. COPYING IN QUANTITY - -If you publish printed copies of the Document numbering more than 100, -and the Document's license notice requires Cover Texts, you must enclose -the copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a publicly-accessible computer-network location containing a complete -Transparent copy of the Document, free of added material, which the -general network-using public has access to download anonymously at no -charge using public-standard network protocols. If you use the latter -option, you must take reasonably prudent steps, when you begin -distribution of Opaque copies in quantity, to ensure that this -Transparent copy will remain thus accessible at the stated location -until at least one year after the last time you distribute an Opaque -copy (directly or through your agents or retailers) of that edition to -the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - - -4. MODIFICATIONS - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: - -A. Use in the Title Page (and on the covers, if any) a title distinct - from that of the Document, and from those of previous versions - (which should, if there were any, be listed in the History section - of the Document). You may use the same title as a previous version - if the original publisher of that version gives permission. -B. List on the Title Page, as authors, one or more persons or entities - responsible for authorship of the modifications in the Modified - Version, together with at least five of the principal authors of the - Document (all of its principal authors, if it has less than five). -C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. -D. Preserve all the copyright notices of the Document. -E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. -F. Include, immediately after the copyright notices, a license notice - giving the public permission to use the Modified Version under the - terms of this License, in the form shown in the Addendum below. -G. Preserve in that license notice the full lists of Invariant Sections - and required Cover Texts given in the Document's license notice. -H. Include an unaltered copy of this License. -I. Preserve the section entitled "History", and its title, and add to - it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence. -J. Preserve the network location, if any, given in the Document for - public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions - it was based on. These may be placed in the "History" section. - You may omit a network location for a work that was published at - least four years before the Document itself, or if the original - publisher of the version it refers to gives permission. -K. In any section entitled "Acknowledgements" or "Dedications", - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements - and/or dedications given therein. -L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section titles. -M. Delete any section entitled "Endorsements". Such a section - may not be included in the Modified Version. -N. Do not retitle any existing section as "Endorsements" - or to conflict in title with any Invariant Section. - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section entitled "Endorsements", provided it contains -nothing but endorsements of your Modified Version by various -parties--for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - - -5. COMBINING DOCUMENTS - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. - -In the combination, you must combine any sections entitled "History" -in the various original documents, forming one section entitled -"History"; likewise combine any sections entitled "Acknowledgements", -and any sections entitled "Dedications". You must delete all sections -entitled "Endorsements." - - -6. COLLECTIONS OF DOCUMENTS - -You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. - -You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. - - -7. AGGREGATION WITH INDEPENDENT WORKS - -A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, does not as a whole count as a Modified Version -of the Document, provided no compilation copyright is claimed for the -compilation. Such a compilation is called an "aggregate", and this -License does not apply to the other self-contained works thus compiled -with the Document, on account of their being thus compiled, if they -are not themselves derivative works of the Document. - -If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one quarter -of the entire aggregate, the Document's Cover Texts may be placed on -covers that surround only the Document within the aggregate. -Otherwise they must appear on covers around the whole aggregate. - - -8. TRANSLATION - -Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License provided that you also include the -original English version of this License. In case of a disagreement -between the translation and the original English version of this -License, the original English version will prevail. - - -9. TERMINATION - -You may not copy, modify, sublicense, or distribute the Document except -as expressly provided for under this License. Any other attempt to -copy, modify, sublicense or distribute the Document is void, and will -automatically terminate your rights under this License. However, -parties who have received copies, or rights, from you under this -License will not have their licenses terminated so long as such -parties remain in full compliance. - - -10. FUTURE REVISIONS OF THIS LICENSE - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. See -http://www.gnu.org/copyleft/. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License "or any later version" applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. - - -ADDENDUM: How to use this License for your documents - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and -license notices just after the title page: - -@smallexample - Copyright (c) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.1 - or any later version published by the Free Software Foundation; - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - A copy of the license is included in the section entitled "GNU - Free Documentation License". -@end smallexample - -If you have no Invariant Sections, write "with no Invariant Sections" -instead of saying which ones are invariant.

PREAMBLE -\" .PP -\" The purpose of this License is to make a manual, textbook, or other -\" written document "free" in the sense of freedom: to assure everyone -\" the effective freedom to copy and redistribute it, with or without -\" modifying it, either commercially or noncommercially. Secondarily, -\" this License preserves for the author and publisher a way to get -\" credit for their work, while not being considered responsible for -\" modifications made by others. -\" .PP -\" This License is a kind of "copyleft", which means that derivative -\" works of the document must themselves be free in the same sense. It -\" complements the GNU General Public License, which is a copyleft -\" license designed for free software. -\" .PP -\" We have designed this License in order to use it for manuals for free -\" software, because free software needs free documentation: a free -\" program should come with manuals providing the same freedoms that the -\" software does. But this License is not limited to software manuals; -\" it can be used for any textual work, regardless of subject matter or -\" whether it is published as a printed book. We recommend this License -\" principally for works whose purpose is instruction or reference. -\" .PP -\" 1. APPLICABILITY AND DEFINITIONS -\" .PP -\" This License applies to any manual or other work that contains a -\" notice placed by the copyright holder saying it can be distributed -\" under the terms of this License. The "Document", below, refers to any -\" such manual or work. Any member of the public is a licensee, and is -\" addressed as "you". -\" .PP -\" A "Modified Version" of the Document means any work containing the -\" Document or a portion of it, either copied verbatim, or with -\" modifications and/or translated into another language. -\" .PP -\" A "Secondary Section" is a named appendix or a front-matter section of -\" the Document that deals exclusively with the relationship of the -\" publishers or authors of the Document to the Document's overall subject -\" (or to related matters) and contains nothing that could fall directly -\" within that overall subject. (For example, if the Document is in part a -\" textbook of mathematics, a Secondary Section may not explain any -\" mathematics.) The relationship could be a matter of historical -\" connection with the subject or with related matters, or of legal, -\" commercial, philosophical, ethical or political position regarding -\" them. -\" .PP -\" The "Invariant Sections" are certain Secondary Sections whose titles -\" are designated, as being those of Invariant Sections, in the notice -\" that says that the Document is released under this License. -\" .PP -\" The "Cover Texts" are certain short passages of text that are listed, -\" as Front-Cover Texts or Back-Cover Texts, in the notice that says that -\" the Document is released under this License. -\" .PP -\" A "Transparent" copy of the Document means a machine-readable copy, -\" represented in a format whose specification is available to the -\" general public, whose contents can be viewed and edited directly and -\" straightforwardly with generic text editors or (for images composed of -\" pixels) generic paint programs or (for drawings) some widely available -\" drawing editor, and that is suitable for input to text formatters or -\" for automatic translation to a variety of formats suitable for input -\" to text formatters. A copy made in an otherwise Transparent file -\" format whose markup has been designed to thwart or discourage -\" subsequent modification by readers is not Transparent. A copy that is -\" not "Transparent" is called "Opaque". -\" .PP -\" Examples of suitable formats for Transparent copies include plain -\" ASCII without markup, Texinfo input format, LaTeX input format, SGML -\" or XML using a publicly available DTD, and standard-conforming simple -\" HTML designed for human modification. Opaque formats include -\" PostScript, PDF, proprietary formats that can be read and edited only -\" by proprietary word processors, SGML or XML for which the DTD and/or -\" processing tools are not generally available, and the -\" machine-generated HTML produced by some word processors for output -\" purposes only. -\" .PP -\" The "Title Page" means, for a printed book, the title page itself, -\" plus such following pages as are needed to hold, legibly, the material -\" this License requires to appear in the title page. For works in -\" formats which do not have any title page as such, "Title Page" means -\" the text near the most prominent appearance of the work's title, -\" preceding the beginning of the body of the text. -\" .PP -\" 2. VERBATIM COPYING -\" .PP -\" You may copy and distribute the Document in any medium, either -\" commercially or noncommercially, provided that this License, the -\" copyright notices, and the license notice saying this License applies -\" to the Document are reproduced in all copies, and that you add no other -\" conditions whatsoever to those of this License. You may not use -\" technical measures to obstruct or control the reading or further -\" copying of the copies you make or distribute. However, you may accept -\" compensation in exchange for copies. If you distribute a large enough -\" number of copies you must also follow the conditions in section 3. -\" .PP -\" You may also lend copies, under the same conditions stated above, and -\" you may publicly display copies. -\" .PP -\" 3. COPYING IN QUANTITY -\" .PP -\" If you publish printed copies of the Document numbering more than 100, -\" and the Document's license notice requires Cover Texts, you must enclose -\" the copies in covers that carry, clearly and legibly, all these Cover -\" Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -\" the back cover. Both covers must also clearly and legibly identify -\" you as the publisher of these copies. The front cover must present -\" the full title with all words of the title equally prominent and -\" visible. You may add other material on the covers in addition. -\" Copying with changes limited to the covers, as long as they preserve -\" the title of the Document and satisfy these conditions, can be treated -\" as verbatim copying in other respects. -\" .PP -\" If the required texts for either cover are too voluminous to fit -\" legibly, you should put the first ones listed (as many as fit -\" reasonably) on the actual cover, and continue the rest onto adjacent -\" pages. -\" .PP -\" If you publish or distribute Opaque copies of the Document numbering -\" more than 100, you must either include a machine-readable Transparent -\" copy along with each Opaque copy, or state in or with each Opaque copy -\" a publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. If you use the latter -\" option, you must take reasonably prudent steps, when you begin -\" distribution of Opaque copies in quantity, to ensure that this -\" Transparent copy will remain thus accessible at the stated location -\" until at least one year after the last time you distribute an Opaque -\" copy (directly or through your agents or retailers) of that edition to -\" the public. -\" .PP -\" It is requested, but not required, that you contact the authors of the -\" Document well before redistributing any large number of copies, to give -\" them a chance to provide you with an updated version of the Document. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" You may copy and distribute a Modified Version of the Document under -\" the conditions of sections 2 and 3 above, provided that you release -\" the Modified Version under precisely this License, with the Modified -\" Version filling the role of the Document, thus licensing distribution -\" and modification of the Modified Version to whoever possesses a copy -\" of it. In addition, you must do these things in the Modified Version: -\" .PP -\" A. Use in the Title Page (and on the covers, if any) a title distinct -\" from that of the Document, and from those of previous versions -\" (which should, if there were any, be listed in the History section -\" of the Document). You may use the same title as a previous version -\" if the original publisher of that version gives permission. -\" .PP -\" B. List on the Title Page, as authors, one or more persons or entities -\" responsible for authorship of the modifications in the Modified -\" Version, together with at least five of the principal authors of the -\" Document (all of its principal authors, if it has less than five). -\" .PP -\" C. State on the Title page the name of the publisher of the -\" Modified Version, as the publisher. -\" .PP -\" D. Preserve all the copyright notices of the Document. -\" .PP -\" E. Add an appropriate copyright notice for your modifications -\" adjacent to the other copyright notices. -\" .PP -\" F. Include, immediately after the copyright notices, a license notice -\" giving the public permission to use the Modified Version under the -\" terms of this License, in the form shown in the Addendum below. -\" Preserve in that license notice the full lists of Invariant Sections -\" and required Cover Texts given in the Document's license notice. -\" .PP -\" H. Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and its title, and add to -\" it an item stating at least the title, year, new authors, and -\" publisher of the Modified Version as given on the Title Page. If -\" there is no section entitled "History" in the Document, create one -\" stating the title, year, authors, and publisher of the Document as -\" given on its Title Page, then add an item describing the Modified -\" Version as stated in the previous sentence. -\" .PP -\" J. Preserve the network location, if any, given in the Document for -\" public access to a Transparent copy of the Document, and likewise -\" the network locations given in the Document for previous versions -\" it was based on. These may be placed in the "History" section. -\" You may omit a network location for a work that was published at -\" least four years before the Document itself, or if the original -\" publisher of the version it refers to gives permission. -\" .PP -\" K. In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" L. Preserve all the Invariant Sections of the Document, -\" unaltered in their text and in their titles. Section numbers -\" or the equivalent are not considered part of the section titles. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" If the Modified Version includes new front-matter sections or -\" appendices that qualify as Secondary Sections and contain no material -\" copied from the Document, you may at your option designate some or all -\" of these sections as invariant. To do this, add their titles to the -\" list of Invariant Sections in the Modified Version's license notice. -\" These titles must be distinct from any other section titles. -\" .PP -\" You may add a section entitled "Endorsements", provided it contains -\" nothing but endorsements of your Modified Version by various -\" parties--for example, statements of peer review or that the text has -\" been approved by an organization as the authoritative definition of a -\" standard. -\" .PP -\" You may add a passage of up to five words as a Front-Cover Text, and a -\" passage of up to 25 words as a Back-Cover Text, to the end of the list -\" of Cover Texts in the Modified Version. Only one passage of -\" Front-Cover Text and one of Back-Cover Text may be added by (or -\" through arrangements made by) any one entity. If the Document already -\" includes a cover text for the same cover, previously added by you or -\" by arrangement made by the same entity you are acting on behalf of, -\" you may not add another; but you may replace the old one, on explicit -\" permission from the previous publisher that added the old one. -\" .PP -\" The author(s) and publisher(s) of the Document do not by this License -\" give permission to use their names for publicity for or to assert or -\" imply endorsement of any Modified Version. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" You may combine the Document with other documents released under this -\" License, under the terms defined in section 4 above for modified -\" versions, provided that you include in the combination all of the -\" Invariant Sections of all of the original documents, unmodified, and -\" list them all as Invariant Sections of your combined work in its -\" license notice. -\" .PP -\" The combined work need only contain one copy of this License, and -\" multiple identical Invariant Sections may be replaced with a single -\" copy. If there are multiple Invariant Sections with the same name but -\" different contents, make the title of each such section unique by -\" adding at the end of it, in parentheses, the name of the original -\" author or publisher of that section if known, or else a unique number. -\" Make the same adjustment to the section titles in the list of -\" Invariant Sections in the license notice of the combined work. -\" .PP -\" In the combination, you must combine any sections entitled "History" -\" in the various original documents, forming one section entitled -\" "History"; likewise combine any sections entitled "Acknowledgements", -\" and any sections entitled "Dedications". You must delete all sections -\" entitled "Endorsements." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License. Any other attempt to -\" copy, modify, sublicense or distribute the Document is void, and will -\" automatically terminate your rights under this License. However, -\" parties who have received copies, or rights, from you under this -\" License will not have their licenses terminated so long as such -\" parties remain in full compliance. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time. Such new -\" versions will be similar in spirit to the present version, but may -\" differ in detail to address new problems or concerns. See -\" http://www.gnu.org/copyleft/. -\" .PP -\" Each version of the License is given a distinguishing version number. -\" If the Document specifies that a particular numbered version of this -\" License "or any later version" applies to it, you have the option of -\" following the terms and conditions either of that specified version or -\" of any later version that has been published (not as a draft) by the -\" Free Software Foundation. If the Document does not specify a version -\" number of this License, you may choose any version ever published (not -\" as a draft) by the Free Software Foundation. -\" .PP - -\" ADDENDUM: How to use this License for your documents -\" .PP -\" To use this License in a document you have written, include a copy of -\" the License in the document and put the following copyright and -\" license notices just after the title page: -\" .PP -\" Copyright (c) YEAR YOUR NAME. -\" Permission is granted to copy, distribute and/or -\" modify this document under the terms of the GNU -\" Free Documentation License, Version 1.1 or any later -\" version published by the Free Software Foundation; -\" with the Invariant Sections being LIST THEIR TITLES, -\" with the Front-Cover Texts being LIST, and with the -\" Back-Cover Texts being LIST. A copy of the license -\" is included in the section entitled "GNU Free -\" Documentation License". -\" .PP -\" If you have no Invariant Sections, write "with no Invariant Sections" -\" instead of saying which ones are invariant. If you have no -\" Front-Cover Texts, write "no Front-Cover Texts" instead of -\" "Front-Cover Texts being LIST"; likewise for Back-Cover Texts. -\" .PP -\" If your document contains nontrivial examples of program code, we -\" recommend releasing these examples in parallel under your choice of -\" free software license, such as the GNU General Public License, -\" to permit their use in free software. diff --git a/contrib/binutils/binutils/objcopy.1 b/contrib/binutils/binutils/objcopy.1 deleted file mode 100644 index a6aa1815fa805..0000000000000 --- a/contrib/binutils/binutils/objcopy.1 +++ /dev/null @@ -1,548 +0,0 @@ -.\" Automatically generated by Pod::Man version 1.02 -.\" Wed May 30 12:24:28 2001 -.\" -.\" Standard preamble: -.\" ====================================================================== -.de Sh \" Subsection heading -.br -.if t .Sp -.ne 5 -.PP -\fB\\$1\fR -.PP -.. -.de Sp \" Vertical space (when we can't use .PP) -.if t .sp .5v -.if n .sp -.. -.de Ip \" List item -.br -.ie \\n(.$>=3 .ne \\$3 -.el .ne 3 -.IP "\\$1" \\$2 -.. -.de Vb \" Begin verbatim text -.ft CW -.nf -.ne \\$1 -.. -.de Ve \" End verbatim text -.ft R - -.fi -.. -.\" Set up some character translations and predefined strings. \*(-- will -.\" give an unbreakable dash, \*(PI will give pi, \*(L" will give a left -.\" double quote, and \*(R" will give a right double quote. | will give a -.\" real vertical bar. \*(C+ will give a nicer C++.

In addition, you must do these things in the Modified Version: -\" .PP -\" A. Use in the Title Page (and on the covers, if any) a title distinct -\" from that of the Document, and from those of previous versions -\" (which should, if there were any, be listed in the History section -\" of the Document).

Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and its title, and add to -\" it an item stating at least the title, year, new authors, and -\" publisher of the Modified Version as given on the Title Page. If -\" there is no section entitled "History" in the Document, create one -\" stating the title, year, authors, and publisher of the Document as -\" given on its Title Page, then add an item describing the Modified -\" Version as stated in the previous sentence. -\" .PP -\" J. Preserve the network location, if any, given in the Document for -\" public access to a Transparent copy of the Document, and likewise -\" the network locations given in the Document for previous versions -\" it was based on. These may be placed in the "History" section. -\" You may omit a network location for a work that was published at -\" least four years before the Document itself, or if the original -\" publisher of the version it refers to gives permission. -\" .PP -\" K. In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" L. Preserve all the Invariant Sections of the Document, -\" unaltered in their text and in their titles. Section numbers -\" or the equivalent are not considered part of the section titles. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" If the Modified Version includes new front-matter sections or -\" appendices that qualify as Secondary Sections and contain no material -\" copied from the Document, you may at your option designate some or all -\" of these sections as invariant. To do this, add their titles to the -\" list of Invariant Sections in the Modified Version's license notice. -\" These titles must be distinct from any other section titles. -\" .PP -\" You may add a section entitled "Endorsements", provided it contains -\" nothing but endorsements of your Modified Version by various -\" parties--for example, statements of peer review or that the text has -\" been approved by an organization as the authoritative definition of a -\" standard. -\" .PP -\" You may add a passage of up to five words as a Front-Cover Text, and a -\" passage of up to 25 words as a Back-Cover Text, to the end of the list -\" of Cover Texts in the Modified Version. Only one passage of -\" Front-Cover Text and one of Back-Cover Text may be added by (or -\" through arrangements made by) any one entity. If the Document already -\" includes a cover text for the same cover, previously added by you or -\" by arrangement made by the same entity you are acting on behalf of, -\" you may not add another; but you may replace the old one, on explicit -\" permission from the previous publisher that added the old one. -\" .PP -\" The author(s) and publisher(s) of the Document do not by this License -\" give permission to use their names for publicity for or to assert or -\" imply endorsement of any Modified Version. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" You may combine the Document with other documents released under this -\" License, under the terms defined in section 4 above for modified -\" versions, provided that you include in the combination all of the -\" Invariant Sections of all of the original documents, unmodified, and -\" list them all as Invariant Sections of your combined work in its -\" license notice. -\" .PP -\" The combined work need only contain one copy of this License, and -\" multiple identical Invariant Sections may be replaced with a single -\" copy. If there are multiple Invariant Sections with the same name but -\" different contents, make the title of each such section unique by -\" adding at the end of it, in parentheses, the name of the original -\" author or publisher of that section if known, or else a unique number. -\" Make the same adjustment to the section titles in the list of -\" Invariant Sections in the license notice of the combined work. -\" .PP -\" In the combination, you must combine any sections entitled "History" -\" in the various original documents, forming one section entitled -\" "History"; likewise combine any sections entitled "Acknowledgements", -\" and any sections entitled "Dedications". You must delete all sections -\" entitled "Endorsements." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License. Any other attempt to -\" copy, modify, sublicense or distribute the Document is void, and will -\" automatically terminate your rights under this License. However, -\" parties who have received copies, or rights, from you under this -\" License will not have their licenses terminated so long as such -\" parties remain in full compliance. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time. Such new -\" versions will be similar in spirit to the present version, but may -\" differ in detail to address new problems or concerns. See -\" http://www.gnu.org/copyleft/. -\" .PP -\" Each version of the License is given a distinguishing version number. -\" If the Document specifies that a particular numbered version of this -\" License "or any later version" applies to it, you have the option of -\" following the terms and conditions either of that specified version or -\" of any later version that has been published (not as a draft) by the -\" Free Software Foundation. If the Document does not specify a version -\" number of this License, you may choose any version ever published (not -\" as a draft) by the Free Software Foundation. -\" .PP - -\" ADDENDUM: How to use this License for your documents -\" .PP -\" To use this License in a document you have written, include a copy of -\" the License in the document and put the following copyright and -\" license notices just after the title page: -\" .PP -\" Copyright (c) YEAR YOUR NAME. -\" Permission is granted to copy, distribute and/or -\" modify this document under the terms of the GNU -\" Free Documentation License, Version 1.1 or any later -\" version published by the Free Software Foundation; -\" with the Invariant Sections being LIST THEIR TITLES, -\" with the Front-Cover Texts being LIST, and with the -\" Back-Cover Texts being LIST.

You may add other material on the covers in addition. -\" Copying with changes limited to the covers, as long as they preserve -\" the title of the Document and satisfy these conditions, can be treated -\" as verbatim copying in other respects. -\" .PP -\" If the required texts for either cover are too voluminous to fit -\" legibly, you should put the first ones listed (as many as fit -\" reasonably) on the actual cover, and continue the rest onto adjacent -\" pages. -\" .PP -\" If you publish or distribute Opaque copies of the Document numbering -\" more than 100, you must either include a machine-readable Transparent -\" copy along with each Opaque copy, or state in or with each Opaque copy -\" a publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. If you use the latter -\" option, you must take reasonably prudent steps, when you begin -\" distribution of Opaque copies in quantity, to ensure that this -\" Transparent copy will remain thus accessible at the stated location -\" until at least one year after the last time you distribute an Opaque -\" copy (directly or through your agents or retailers) of that edition to -\" the public. -\" .PP -\" It is requested, but not required, that you contact the authors of the -\" Document well before redistributing any large number of copies, to give -\" them a chance to provide you with an updated version of the Document. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" You may copy and distribute a Modified Version of the Document under -\" the conditions of sections 2 and 3 above, provided that you release -\" the Modified Version under precisely this License, with the Modified -\" Version filling the role of the Document, thus licensing distribution -\" and modification of the Modified Version to whoever possesses a copy -\" of it. In addition, you must do these things in the Modified Version: -\" .PP -\" A. Use in the Title Page (and on the covers, if any) a title distinct -\" from that of the Document, and from those of previous versions -\" (which should, if there were any, be listed in the History section -\" of the Document). You may use the same title as a previous version -\" if the original publisher of that version gives permission. -\" .PP -\" B. List on the Title Page, as authors, one or more persons or entities -\" responsible for authorship of the modifications in the Modified -\" Version, together with at least five of the principal authors of the -\" Document (all of its principal authors, if it has less than five). -\" .PP -\" C. State on the Title page the name of the publisher of the -\" Modified Version, as the publisher. -\" .PP -\" D. Preserve all the copyright notices of the Document. -\" .PP -\" E. Add an appropriate copyright notice for your modifications -\" adjacent to the other copyright notices. -\" .PP -\" F. Include, immediately after the copyright notices, a license notice -\" giving the public permission to use the Modified Version under the -\" terms of this License, in the form shown in the Addendum below. -\" Preserve in that license notice the full lists of Invariant Sections -\" and required Cover Texts given in the Document's license notice. -\" .PP -\" H. Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and its title, and add to -\" it an item stating at least the title, year, new authors, and -\" publisher of the Modified Version as given on the Title Page. If -\" there is no section entitled "History" in the Document, create one -\" stating the title, year, authors, and publisher of the Document as -\" given on its Title Page, then add an item describing the Modified -\" Version as stated in the previous sentence. -\" .PP -\" J. Preserve the network location, if any, given in the Document for -\" public access to a Transparent copy of the Document, and likewise -\" the network locations given in the Document for previous versions -\" it was based on. These may be placed in the "History" section. -\" You may omit a network location for a work that was published at -\" least four years before the Document itself, or if the original -\" publisher of the version it refers to gives permission. -\" .PP -\" K. In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" L. Preserve all the Invariant Sections of the Document, -\" unaltered in their text and in their titles. Section numbers -\" or the equivalent are not considered part of the section titles. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" If the Modified Version includes new front-matter sections or -\" appendices that qualify as Secondary Sections and contain no material -\" copied from the Document, you may at your option designate some or all -\" of these sections as invariant. To do this, add their titles to the -\" list of Invariant Sections in the Modified Version's license notice. -\" These titles must be distinct from any other section titles. -\" .PP -\" You may add a section entitled "Endorsements", provided it contains -\" nothing but endorsements of your Modified Version by various -\" parties--for example, statements of peer review or that the text has -\" been approved by an organization as the authoritative definition of a -\" standard. -\" .PP -\" You may add a passage of up to five words as a Front-Cover Text, and a -\" passage of up to 25 words as a Back-Cover Text, to the end of the list -\" of Cover Texts in the Modified Version. Only one passage of -\" Front-Cover Text and one of Back-Cover Text may be added by (or -\" through arrangements made by) any one entity. If the Document already -\" includes a cover text for the same cover, previously added by you or -\" by arrangement made by the same entity you are acting on behalf of, -\" you may not add another; but you may replace the old one, on explicit -\" permission from the previous publisher that added the old one. -\" .PP -\" The author(s) and publisher(s) of the Document do not by this License -\" give permission to use their names for publicity for or to assert or -\" imply endorsement of any Modified Version. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" You may combine the Document with other documents released under this -\" License, under the terms defined in section 4 above for modified -\" versions, provided that you include in the combination all of the -\" Invariant Sections of all of the original documents, unmodified, and -\" list them all as Invariant Sections of your combined work in its -\" license notice. -\" .PP -\" The combined work need only contain one copy of this License, and -\" multiple identical Invariant Sections may be replaced with a single -\" copy. If there are multiple Invariant Sections with the same name but -\" different contents, make the title of each such section unique by -\" adding at the end of it, in parentheses, the name of the original -\" author or publisher of that section if known, or else a unique number. -\" Make the same adjustment to the section titles in the list of -\" Invariant Sections in the license notice of the combined work. -\" .PP -\" In the combination, you must combine any sections entitled "History" -\" in the various original documents, forming one section entitled -\" "History"; likewise combine any sections entitled "Acknowledgements", -\" and any sections entitled "Dedications". You must delete all sections -\" entitled "Endorsements." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License. Any other attempt to -\" copy, modify, sublicense or distribute the Document is void, and will -\" automatically terminate your rights under this License. However, -\" parties who have received copies, or rights, from you under this -\" License will not have their licenses terminated so long as such -\" parties remain in full compliance. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time. Such new -\" versions will be similar in spirit to the present version, but may -\" differ in detail to address new problems or concerns. See -\" http://www.gnu.org/copyleft/. -\" .PP -\" Each version of the License is given a distinguishing version number. -\" If the Document specifies that a particular numbered version of this -\" License "or any later version" applies to it, you have the option of -\" following the terms and conditions either of that specified version or -\" of any later version that has been published (not as a draft) by the -\" Free Software Foundation. If the Document does not specify a version -\" number of this License, you may choose any version ever published (not -\" as a draft) by the Free Software Foundation. -\" .PP - -\" ADDENDUM: How to use this License for your documents -\" .PP -\" To use this License in a document you have written, include a copy of -\" the License in the document and put the following copyright and -\" license notices just after the title page: -\" .PP -\" Copyright (c) YEAR YOUR NAME. -\" Permission is granted to copy, distribute and/or -\" modify this document under the terms of the GNU -\" Free Documentation License, Version 1.1 or any later -\" version published by the Free Software Foundation; -\" with the Invariant Sections being LIST THEIR TITLES, -\" with the Front-Cover Texts being LIST, and with the -\" Back-Cover Texts being LIST.

You must delete all sections -\" entitled "Endorsements." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" Translation is considered a kind of modification, so you may -\" distribute translations of the Document under the terms of section 4. -\" Replacing Invariant Sections with translations requires special -\" permission from their copyright holders, but you may include -\" translations of some or all Invariant Sections in addition to the -\" original versions of these Invariant Sections. You may include a -\" translation of this License provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License. Any other attempt to -\" copy, modify, sublicense or distribute the Document is void, and will -\" automatically terminate your rights under this License. However, -\" parties who have received copies, or rights, from you under this -\" License will not have their licenses terminated so long as such -\" parties remain in full compliance. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time.

PREAMBLE -\" .PP -\" The purpose of this License is to make a manual, textbook, or other -\" written document "free" in the sense of freedom: to assure everyone -\" the effective freedom to copy and redistribute it, with or without -\" modifying it, either commercially or noncommercially. Secondarily, -\" this License preserves for the author and publisher a way to get -\" credit for their work, while not being considered responsible for -\" modifications made by others. -\" .PP -\" This License is a kind of "copyleft", which means that derivative -\" works of the document must themselves be free in the same sense. It -\" complements the GNU General Public License, which is a copyleft -\" license designed for free software. -\" .PP -\" We have designed this License in order to use it for manuals for free -\" software, because free software needs free documentation: a free -\" program should come with manuals providing the same freedoms that the -\" software does. But this License is not limited to software manuals; -\" it can be used for any textual work, regardless of subject matter or -\" whether it is published as a printed book. We recommend this License -\" principally for works whose purpose is instruction or reference. -\" .PP -\" 1. APPLICABILITY AND DEFINITIONS -\" .PP -\" This License applies to any manual or other work that contains a -\" notice placed by the copyright holder saying it can be distributed -\" under the terms of this License. The "Document", below, refers to any -\" such manual or work. Any member of the public is a licensee, and is -\" addressed as "you". -\" .PP -\" A "Modified Version" of the Document means any work containing the -\" Document or a portion of it, either copied verbatim, or with -\" modifications and/or translated into another language. -\" .PP -\" A "Secondary Section" is a named appendix or a front-matter section of -\" the Document that deals exclusively with the relationship of the -\" publishers or authors of the Document to the Document's overall subject -\" (or to related matters) and contains nothing that could fall directly -\" within that overall subject. (For example, if the Document is in part a -\" textbook of mathematics, a Secondary Section may not explain any -\" mathematics.) The relationship could be a matter of historical -\" connection with the subject or with related matters, or of legal, -\" commercial, philosophical, ethical or political position regarding -\" them. -\" .PP -\" The "Invariant Sections" are certain Secondary Sections whose titles -\" are designated, as being those of Invariant Sections, in the notice -\" that says that the Document is released under this License. -\" .PP -\" The "Cover Texts" are certain short passages of text that are listed, -\" as Front-Cover Texts or Back-Cover Texts, in the notice that says that -\" the Document is released under this License. -\" .PP -\" A "Transparent" copy of the Document means a machine-readable copy, -\" represented in a format whose specification is available to the -\" general public, whose contents can be viewed and edited directly and -\" straightforwardly with generic text editors or (for images composed of -\" pixels) generic paint programs or (for drawings) some widely available -\" drawing editor, and that is suitable for input to text formatters or -\" for automatic translation to a variety of formats suitable for input -\" to text formatters. A copy made in an otherwise Transparent file -\" format whose markup has been designed to thwart or discourage -\" subsequent modification by readers is not Transparent. A copy that is -\" not "Transparent" is called "Opaque". -\" .PP -\" Examples of suitable formats for Transparent copies include plain -\" ASCII without markup, Texinfo input format, LaTeX input format, SGML -\" or XML using a publicly available DTD, and standard-conforming simple -\" HTML designed for human modification. Opaque formats include -\" PostScript, PDF, proprietary formats that can be read and edited only -\" by proprietary word processors, SGML or XML for which the DTD and/or -\" processing tools are not generally available, and the -\" machine-generated HTML produced by some word processors for output -\" purposes only. -\" .PP -\" The "Title Page" means, for a printed book, the title page itself, -\" plus such following pages as are needed to hold, legibly, the material -\" this License requires to appear in the title page. For works in -\" formats which do not have any title page as such, "Title Page" means -\" the text near the most prominent appearance of the work's title, -\" preceding the beginning of the body of the text. -\" .PP -\" 2. VERBATIM COPYING -\" .PP -\" You may copy and distribute the Document in any medium, either -\" commercially or noncommercially, provided that this License, the -\" copyright notices, and the license notice saying this License applies -\" to the Document are reproduced in all copies, and that you add no other -\" conditions whatsoever to those of this License. You may not use -\" technical measures to obstruct or control the reading or further -\" copying of the copies you make or distribute. However, you may accept -\" compensation in exchange for copies. If you distribute a large enough -\" number of copies you must also follow the conditions in section 3. -\" .PP -\" You may also lend copies, under the same conditions stated above, and -\" you may publicly display copies. -\" .PP -\" 3. COPYING IN QUANTITY -\" .PP -\" If you publish printed copies of the Document numbering more than 100, -\" and the Document's license notice requires Cover Texts, you must enclose -\" the copies in covers that carry, clearly and legibly, all these Cover -\" Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -\" the back cover. Both covers must also clearly and legibly identify -\" you as the publisher of these copies. The front cover must present -\" the full title with all words of the title equally prominent and -\" visible. You may add other material on the covers in addition. -\" Copying with changes limited to the covers, as long as they preserve -\" the title of the Document and satisfy these conditions, can be treated -\" as verbatim copying in other respects. -\" .PP -\" If the required texts for either cover are too voluminous to fit -\" legibly, you should put the first ones listed (as many as fit -\" reasonably) on the actual cover, and continue the rest onto adjacent -\" pages. -\" .PP -\" If you publish or distribute Opaque copies of the Document numbering -\" more than 100, you must either include a machine-readable Transparent -\" copy along with each Opaque copy, or state in or with each Opaque copy -\" a publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. If you use the latter -\" option, you must take reasonably prudent steps, when you begin -\" distribution of Opaque copies in quantity, to ensure that this -\" Transparent copy will remain thus accessible at the stated location -\" until at least one year after the last time you distribute an Opaque -\" copy (directly or through your agents or retailers) of that edition to -\" the public. -\" .PP -\" It is requested, but not required, that you contact the authors of the -\" Document well before redistributing any large number of copies, to give -\" them a chance to provide you with an updated version of the Document. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" You may copy and distribute a Modified Version of the Document under -\" the conditions of sections 2 and 3 above, provided that you release -\" the Modified Version under precisely this License, with the Modified -\" Version filling the role of the Document, thus licensing distribution -\" and modification of the Modified Version to whoever possesses a copy -\" of it. In addition, you must do these things in the Modified Version: -\" .PP -\" A. Use in the Title Page (and on the covers, if any) a title distinct -\" from that of the Document, and from those of previous versions -\" (which should, if there were any, be listed in the History section -\" of the Document).

List on the Title Page, as authors, one or more persons or entities -\" responsible for authorship of the modifications in the Modified -\" Version, together with at least five of the principal authors of the -\" Document (all of its principal authors, if it has less than five). -\" .PP -\" C.

Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and its title, and add to -\" it an item stating at least the title, year, new authors, and -\" publisher of the Modified Version as given on the Title Page.

COMBINING DOCUMENTS -\" .PP -\" You may combine the Document with other documents released under this -\" License, under the terms defined in section 4 above for modified -\" versions, provided that you include in the combination all of the -\" Invariant Sections of all of the original documents, unmodified, and -\" list them all as Invariant Sections of your combined work in its -\" license notice. -\" .PP -\" The combined work need only contain one copy of this License, and -\" multiple identical Invariant Sections may be replaced with a single -\" copy.

COLLECTIONS OF DOCUMENTS -\" .PP -\" You may make a collection consisting of the Document and other documents -\" released under this License, and replace the individual copies of this -\" License in the various documents with a single copy that is included in -\" the collection, provided that you follow the rules of this License for -\" verbatim copying of each of the documents in all other respects. -\" .PP -\" You may extract a single document from such a collection, and distribute -\" it individually under this License, provided you insert a copy of this -\" License into the extracted document, and follow this License in all -\" other respects regarding verbatim copying of that document. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" A compilation of the Document or its derivatives with other separate -\" and independent documents or works, in or on a volume of a storage or -\" distribution medium, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation.

In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" You may not copy, modify, sublicense, or distribute the Document except -\" as expressly provided for under this License.

Most of the common terms have been used for many -different concepts such that their meanings have become ambiguous to the -point of being confusing. Typically, we only guess at their meanings -from context and we frequently guess wrong. - -This document uses very few terms by comparison. The intent is to make -the concepts as clear as possible in order to convey the usage and -intent of these tools. - -@emph{Programs} run on @emph{machines}. Programs are very nearly always -written in @emph{source}. Programs are @emph{built} from source. -@emph{Compilation} is a process that is frequently, but not always, used -when building programs. -@cindex Programs -@cindex Machines -@cindex Source -@cindex Building -@cindex Compilation - -@menu -* Host Environments:: Host Environments -* Configuration Time Options:: Configuration Time Options -@end menu - -@node Host Environments, Configuration Time Options, Some Basic Terms, Some Basic Terms -@section Host Environments - -@cindex host -In this document, the word @emph{host} refers to the environment in -which the source in question will be compiled. @emph{host} and -@emph{host name} have nothing to do with the proper name of your host, -like @emph{ucbvax}, @emph{prep.ai.mit.edu} or @emph{att.com}. Instead -they refer to things like @emph{sun4} and @emph{dec3100}. - -Forget for a moment that this particular directory of source is the -source for a development environment. Instead, pretend that it is the -source for a simpler, more mundane, application, say, a desk calculator. - -Source that can be compiled in more than one environment, generally -needs to be set up for each environment explicitly. Here we refer to -that process as configuration. That is, we configure the source for a -host. - -For example, if we wanted to configure our mythical desk calculator to -compile on a SparcStation, we might configure for host sun4. With our -configuration system: - -@example -cd desk-calculator ; ./configure sun4 -@end example - -@noindent -does the trick. @code{configure} is a shell script that sets up Makefiles, -subdirectories, and symbolic links appropriate for compiling the source -on a sun4. - -The @emph{host} environment does not necessarily refer to the machine on -which the tools are built. It is possible to provide a sun3 development -environment on a sun4. If we wanted to use a cross compiler on the sun4 -to build a program intended to be run on a sun3, we would configure the -source for sun3. - -@example -cd desk-calculator ; ./configure sun3 -@end example - -@noindent -The fact that we are actually building the program on a sun4 makes no -difference if the sun3 cross compiler presents an environment that looks -like a sun3 from the point of view of the desk calculator source code. -Specifically, the environment is a sun3 environment if the header files, -predefined symbols, and libraries appear as they do on a sun3. - -Nor does the host environment refer to the the machine on which the -program to be built will run. It is possible to provide a sun3 -emulation environment on a sun4 such that programs built in a sun3 -development environment actually run on the sun4. This technique is -often used within individual programs to remedy deficiencies in the host -operating system. For example, some operating systems do not provide -the @code{bcopy} function and so it is emulated using the -@code{memcpy} funtion. - -Host environment simply refers to the environment in which the program -will be built from the source. - - -@node Configuration Time Options, , Host Environments, Some Basic Terms -@section Configuration Time Options - -Many programs have compile time options. That is, features of the -program that are either compiled into the program or not based on a -choice made by the person who builds the program. We refer to these as -@emph{configuration options}. For example, our desk calculator might be -capable of being compiled into a program that either uses infix notation -or postfix as a configuration option. For a sun3, to choose infix you -might use: - -@example -./configure sun3 --enable-notation=infix -@end example - -@noindent -while for a sun4 with postfix you might use: - -@example -./configure sun4 --enable-notation=postfix -@end example - -If we wanted to build both at the same time, the intermediate pieces -used in the build process must be kept separate. - -@example -mkdir ../objdir.sun4 -(cd ../objdir.sun4 ; ../configure sun4 --enable-notation=postfix --srcdir=../src) -mkdir ../objdir.sun3 -(cd ../objdir.sun3 ; ../configure sun3 --enable-notation=infix --srcdir=../src) -@end example - -@noindent -will create subdirectories for the intermediate pieces of the sun4 and -sun3 configurations. This is necessary as previous systems were only -capable of one configuration at a time. Otherwise, a second -configuration would write over the first. We've chosen to retain this -behaviour so the obj directories and the @code{--srcdir} configuration -option are necessary to get the new behaviour. The order of the -arguments doesn't matter. There should be exactly one argument without -a leading @samp{-} and that argument will be assumed to be the host -name. - -From here on the examples will assume that you want to build the tools -@emph{in place} and won't show the @code{--srcdir} option, but remember -that it is available. - -In order to actually install the program, the configuration system needs -to know where you would like the program installed. The default -location is @file{/usr/local}. We refer to this location as -@code{$(prefix)}. All user visible programs will be installed in -@file{@code{$(prefix)}/bin}. All other programs and files will be -installed in a subdirectory of @file{@code{$(prefix)}/lib}. - -You can only change @code{$(prefix)} as a configuration time -option. - -@example -./configure sun4 --enable-notation=postfix --prefix=/local -@end example - -@noindent -Will configure the source such that: - -@example -make install -@end example - -@noindent -will put its programs in @file{/local/bin} and @file{/local/lib/gcc}. -If you change @code{$(prefix)} after building the source, you will need -to: - -@example -make clean -@end example - -@noindent -before the change will be propogated properly. This is because some -tools need to know the locations of other tools. - -With these concepts in mind, we can drop the desk calculator example and -move on to the application that resides in these directories, namely, -the source to a development environment. - -@node Specifics., Building Development Environments, Some Basic Terms, top -@chapter Specifics - -The @sc{gnu} Development Tools can be built on a wide variety of hosts. So, -of course, they must be configured. Like the last example, - -@example -./configure sun4 --prefix=/local -./configure sun3 --prefix=/local -@end example - -@noindent -will configure the source to be built in subdirectories, in order to -keep the intermediate pieces separate, and to be installed in -@file{/local}. - -When built with suitable development environments, these will be native -tools. We'll explain the term @emph{native} later. - -@node Building Development Environments, A Walk Through, Specifics., top -@chapter Building Development Environments - -@cindex Target - -The @sc{gnu} development tools can not only be built in a -number of host development environments, they can also be configured to -create a number of different development environments on each of those -hosts. We refer to a specific development environment created as a -@emph{target}. That is, the word @emph{target} refers to the development -environment produced by compiling this source and installing the -resulting programs. - -For the @sc{gnu} development tools, the default target is the -same as the host. That is, the development environment produced is -intended to be compatible with the environment used to build the tools. - -In the example above, we created two configurations, one for sun4 and -one for sun3. The first configuration is expecting to be built in a -sun4 development environment, to create a sun4 development environment. -It doesn't necessarily need to be built on a sun4 if a sun4 development -environment is available elsewhere. Likewise, if the available sun4 -development environment produces executables intended for something -other than sun4, then the development environment built from this sun4 -configuration will run on something other than a sun4. From the point -of view of the configuration system and the @sc{gnu} development tools -source, this doesn't matter. What matters is that they will be built in -a sun4 environment. - -Similarly, the second configuration given above is expecting to be built -in a sun3 development environment, to create a sun3 development -environment. - -The development environment produced is a configuration time option, -just like @code{$(prefix)}. - -@example -./configure sun4 --prefix=/local --target=sun3 -./configure sun3 --prefix=/local --target=sun4 -@end example - -In this example, like before, we create two configurations.

The second is intended to be built in a -sun3 environment, in subdirectories, to be installed in @file{/local}. - -Unlike the previous example, the first configuration will produce a sun3 -development environment, perhaps even suitable for building the second -configuration. Likewise, the second configuration will produce a sun4 -development environment, perhaps even suitable for building the first -configuration. - -The development environment used to build these configurations will -determine the machines on which the resulting development environments -can be used. - - -@node A Walk Through, Final Notes, Building Development Environments, top -@chapter A Walk Through - - -@menu -* Native Development Environments:: Native Development Environments -* Emulation Environments:: Emulation Environments -* Simple Cross Environments:: Simple Cross Environments -* Crossing Into Targets:: Crossing Into Targets -* Canadian Cross:: Canadian Cross -@end menu - -@node Native Development Environments, Emulation Environments, A Walk Through, A Walk Through -@section Native Development Environments - -Let us assume for a moment that you have a sun4 and that with your sun4 -you received a development environment.

For now, let's pretend -that you used the native development environment that came with your -sun4 to bootstrap the release and let's call the new -development environment @emph{stage1}. - -Why bother? Well, most people find that the @sc{gnu} development -environment builds programs that run faster and take up less space than -the native development environments that came with their machines. Some -people didn't get development environments with their machines and some -people just like using the @sc{gnu} tools better than using other tools. - -@cindex Stage2 -While you're at it, if the @sc{gnu} tools produce better programs, maybe you -should use them to build the @sc{gnu} tools.

There are many -different types of cross development environments but most fall into one -of three basic categories. - - -@node Emulation Environments, Simple Cross Environments, Native Development Environments, A Walk Through -@section Emulation Environments - -@cindex Emulation -The first category of cross development environment is called -@emph{emulation}. There are two primary types of emulation, but both -types result in programs that run on the native host. - -@cindex Software emulation -@cindex Software emulator -The first type is @emph{software emulation}. This form of cross -development environment involves a native program that when run on the -native host, is capable of interpreting, and in most aspects running, a -program intended for some other machine. This technique is typically -used when the other machine is either too expensive, too slow, too fast, -or not available, perhaps because it hasn't yet been built. The native, -interpreting program is called a @emph{software emulator}. - -The @sc{gnu} Development Tools do not currently include any software -emulators. Some do exist and the @sc{gnu} Development Tools can be -configured to create simple cross development environments for with -these emulators. More on this later. - -The second type of emulation is when source intended for some other -development environment is built into a program intended for the native -host. The concepts of operating system universes and hosted operating -systems are two such development environments. - -@node Simple Cross Environments, Crossing Into Targets, Emulation Environments, A Walk Through -@section Simple Cross Environments - -@example -./configure sun4 --target=a29k -@end example - -@noindent -will configure the tools such that when compiled in a sun4 development -environment the resulting development environment can be used to create -programs intended for an a29k. Again, this does not necessarily mean -that the new development environment can be run on a sun4. That would -depend on the development environment used to build these tools. - -Earlier you saw how to configure the tools to build a native development -environment, that is, a development environment that runs on your sun4 -and builds programs for your sun4. Let's pretend that you use stage3 to -build this simple cross configuration and let's call the new development -environment gcc-a29k. Remember that this is a native build. Gcc-a29k -is a collection of native programs intended to run on your sun4. That's -what stage3 builds, programs for your sun4. Gcc-a29k represents an a29k -development environment that builds programs intended to run on an a29k. -But, remember, gcc-a29k runs on your sun4. Programs built with gcc-a29k -will run on your sun4 only with the help of an appropriate software -emulator. - -@cindex Simple cross -@cindex Crossing to -Building gcc-a29k is also a bootstrap but of a slightly different sort. -We call gcc-a29k a @emph{simple cross} environment and using gcc-a29k to -build a program intended for a29k is called @emph{crossing to} a29k. -Simple cross environments are the second category of cross development -environments. - - -@node Crossing Into Targets, Canadian Cross, Simple Cross Environments, A Walk Through -@section Crossing Into Targets - -@example -./configure a29k --target=a29k -@end example - -@noindent -will configure the tools such that when compiled in an a29k development -environment, the resulting development environment can be used to create -programs intended for an a29k.

Let's pretend you use -gcc-a29k to build the current configuration. - -Gcc-a29k builds programs intended for the a29k so the new development -environment will be intended for use on an a29k. That is, this new gcc -consists of programs that are foreign to your sun4. They cannot be run -on your sun4. - -@cindex Crossing into -The process of building this configuration is a another bootstrap. This -bootstrap is also a cross to a29k. Because this type of build is both a -bootstrap and a cross to a29k, it is sometimes referred to as a -@emph{cross into} a29k. This new development environment isn't really a -cross development environment at all. It is intended to run on an a29k -to produce programs for an a29k. You'll remember that this makes it, by -definition, an a29k native compiler. @emph{Crossing into} has been -introduced here not because it is a type of cross development -environment, but because it is frequently mistaken as one. The process -is @emph{a cross} but the resulting development environment is a native -development environment. - -You could not have built this configuration with stage3, because stage3 -doesn't provide an a29k environment. Instead it provides a sun4 -environment. - -If you happen to have an a29k lying around, you could now use this fresh -development environment on the a29k to three-stage these tools all over -again. This process would look just like it did when we built the -native sun4 development environment because we would be building another -native development environment, this one on a29k. - - -@node Canadian Cross, , Crossing Into Targets, A Walk Through -@section Canadian Cross - -So far you've seen that our development environment source must be -configured for a specific host and for a specific target. You've also -seen that the resulting development environment depends on the -development environment used in the build process. - -When all four match identically, that is, the configured host, the -configured target, the environment presented by the development -environment used in the build, and the machine on which the resulting -development environment is intended to run, then the new development -environment will be a native development environment. - -When all four match except the configured host, then we can assume that -the development environment used in the build is some form of library -emulation. - -When all four match except for the configured target, then the resulting -development environment will be a simple cross development environment. - -When all four match except for the host on which the development -environment used in the build runs, the build process is a @emph{cross into} -and the resulting development environment will be native to some other -machine. - -Most of the other permutations do exist in some form, but only one more -is interesting to the current discussion. - -@example -./configure a29k --target=sun3 -@end example - -@noindent -will configure the tools such that when compiled in an a29k development -environment, the resulting development environment can be used to create -programs intended for a sun3. Again, this does not necessarily mean -that the new development environment can be run on an a29k. That would -depend on the development environment used to build these tools. - -If you are still following along, then you have two a29k development -environments, the native development environment that runs on a29k, and -the simple cross that runs on your sun4. If you use the a29k native -development environment on the a29k, you will be doing the same thing we -did a while back, namely building a simple cross from a29k to sun3. -Let's pretend that instead, you use gcc-a29k, the simple cross -development environment that runs on sun4 but produces programs for -a29k. - -The resulting development environment will run on a29k because that's -what gcc-a29k builds, a29k programs. This development environment will -produce programs for a sun3 because that is how it was configured. This -means that the resulting development environment is a simple cross. - -@cindex Canadian Cross -@cindex Three party cross -There really isn't a common name for this process because very few -development environments are capable of being configured this -extensively. For the sake of discussion, let's call this process a -@emph{Canadian cross}. It's a three party cross, Canada has a three -party system, hence Canadian Cross. - -@node Final Notes, Index, A Walk Through, top -@chapter Final Notes - -By @emph{configures}, I mean that links, Makefile, .gdbinit, and -config.status are built. Configuration is always done from the source -directory. - -@table @code - -@item ./configure @var{name} -configures this directory, perhaps recursively, for a single host+target -pair where the host and target are both @var{name}.

The scripts also -create a @file{.gdbinit} if appropriate but this is not tailored. - -The Makefile is created by prepending some variable definitions to a -Makefile template called @file{Makefile.in} and then inserting host and -target specific Makefile fragments. The variables are set based on the -chosen host+target pair and build style, that is, if you use -@code{--srcdir} or not. The host and target specific Makefile may or may -not exist. - -@itemize @bullet - -@item -Makefiles can be edited directly, but those changes will eventually be -lost. Changes intended to be permanent for a specific host should be -made to the host specific Makefile fragment. This should be in -@file{./config/mh-@var{host}} if it exists.

Changes intended to be permanent for the directory should be -made in @file{Makefile.in}.

All programs are built using a simple, standardized, two step -process. The program builder need not install any special tools in -order to build the program. - -@node Tools -@section Tools - -The GNU configure and build system is comprised of several different -tools. Program developers must build and install all of these tools. - -People who just want to build programs from distributed sources normally -do not need any special tools beyond a Unix shell, a make program, and a -C compiler. - -@table @asis -@item autoconf -provides a general portability framework, based on testing the features -of the host system at build time. -@item automake -a system for describing how to build a program, permitting the developer -to write a simplified @file{Makefile}. -@item libtool -a standardized approach to building shared libraries. -@item gettext -provides a framework for translation of text messages into other -languages; not really discussed in this document. -@item m4 -autoconf requires the GNU version of m4; the standard Unix m4 does not -suffice. -@item perl -automake requires perl. -@end table - -@node History -@section History -@cindex history - -This is a very brief and probably inaccurate history. - -As the number of Unix variants increased during the 1980s, it became -harder to write programs which could run on all variants. While it was -often possible to use @code{#ifdef} to identify particular systems, -developers frequently did not have access to every system, and the -characteristics of some systems changed from version to version. - -By 1992, at least three different approaches had been developed: -@itemize @bullet -@item -The Metaconfig program, by Larry Wall, Harlan Stenn, and Raphael -Manfredi. -@item -The Cygnus configure script, by K. Richard Pixley, and the gcc configure -script, by Richard Stallman. These use essentially the same approach, -and the developers communicated regularly. -@item -The autoconf program, by David MacKenzie. -@end itemize - -The Metaconfig program is still used for Perl and a few other programs. -It is part of the Dist package. I do not know if it is being developed. - -In 1994, David MacKenzie and others modified autoconf to incorporate all -the features of Cygnus configure. Since then, there has been a slow but -steady conversion of GNU programs from Cygnus configure to autoconf. gcc -has been converted, eliminating the gcc configure script. - -GNU autoconf was regularly maintained until late 1996. As of this -writing in June, 1998, it has no public maintainer. - -Most programs are built using the make program, which requires the -developer to write Makefiles describing how to build the programs. -Since most programs are built in pretty much the same way, this led to a -lot of duplication. - -The X Window system is built using the imake tool, which uses a database -of rules to eliminate the duplication. However, building a tool which -was developed using imake requires that the builder have imake -installed, violating one of the goals of the GNU system. - -The new BSD make provides a standard library of Makefile fragments, -which permits developers to write very simple Makefiles. However, this -requires that the builder install the new BSD make program. - -In 1994, David MacKenzie wrote the first version of automake, which -permitted writing a simple build description which was converted into a -Makefile which could be used by the standard make program. In 1995, Tom -Tromey completely rewrote automake in Perl, and he continues to enhance -it. - -Various free packages built libraries, and by around 1995 several -included support to build shared libraries on various platforms. -However, there was no consistent approach. In early 1996, Gordon -Matzigkeit began working on libtool, which provided a standardized -approach to building shared libraries. This was integrated into -automake from the start. - -The development of automake and libtool was driven by the GNITS project, -a group of GNU maintainers who designed standardized tools to help meet -the GNU coding standards. - -@node Building -@section Building - -Most readers of this document should already know how to build a tool by -running @samp{configure} and @samp{make}. This section may serve as a -quick introduction or reminder. - -Building a tool is normally as simple as running @samp{configure} -followed by @samp{make}. You should normally run @samp{configure} from -an empty directory, using some path to refer to the @samp{configure} -script in the source directory. The directory in which you run -@samp{configure} is called the @dfn{object directory}. - -In order to use a object directory which is different from the source -directory, you must be using the GNU version of @samp{make}, which has -the required @samp{VPATH} support. Despite this restriction, using a -different object directory is highly recommended: -@itemize @bullet -@item -It keeps the files generated during the build from cluttering up your -sources. -@item -It permits you to remove the built files by simply removing the entire -build directory. -@item -It permits you to build from the same sources with several sets of -configure options simultaneously. -@end itemize - -If you don't have GNU @samp{make}, you will have to run @samp{configure} -in the source directory. All GNU packages should support this; in -particular, GNU packages should not assume the presence of GNU -@samp{make}. - -After running @samp{configure}, you can build the tools by running -@samp{make}. - -To install the tools, run @samp{make install}. Installing the tools -will copy the programs and any required support files to the -@dfn{installation directory}. The location of the installation -directory is controlled by @samp{configure} options, as described below. - -In the Cygnus tree at present, the info files are built and installed as -a separate step. To build them, run @samp{make info}. To install them, -run @samp{make install-info}. - -All @samp{configure} scripts support a wide variety of options. The -most interesting ones are @samp{--with} and @samp{--enable} options -which are generally specific to particular tools. You can usually use -the @samp{--help} option to get a list of interesting options for a -particular configure script. - -The only generic options you are likely to use are the @samp{--prefix} -and @samp{--exec-prefix} options. These options are used to specify the -installation directory. - -The directory named by the @samp{--prefix} option will hold machine -independent files such as info files. - -The directory named by the @samp{--exec-prefix} option, which is -normally a subdirectory of the @samp{--prefix} directory, will hold -machine dependent files such as executables. - -The default for @samp{--prefix} is @file{/usr/local}. The default for -@samp{--exec-prefix} is the value used for @samp{--prefix}. - -The convention used in Cygnus releases is to use a @samp{--prefix} -option of @file{/usr/cygnus/@var{release}}, where @var{release} is the -name of the release, and to use a @samp{--exec-prefix} option of -@file{/usr/cygnus/@var{release}/H-@var{host}}, where @var{host} is the -configuration name of the host system (@pxref{Configuration Names}). - -Do not use either the source or the object directory as the installation -directory. That will just lead to confusion. - -@node Getting Started -@chapter Getting Started - -To start using the GNU configure and build system with your software -package, you must write three files, and you must run some tools to -manually generate additional files. - -@menu -* Write configure.in:: Write configure.in. -* Write Makefile.am:: Write Makefile.am. -* Write acconfig.h:: Write acconfig.h. -* Generate files:: Generate files. -* Getting Started Example:: Example. -@end menu - -@node Write configure.in -@section Write configure.in -@cindex @file{configure.in}, writing - -You must first write the file @file{configure.in}.

Your code can then use -@samp{#ifdef} to test whether it is safe to call @samp{gettimeofday}. - -If you have an existing body of code, the @samp{autoscan} program may -help identify potential portability problems, and hence configure tests -that you will want to use. -@ifnothtml -@xref{Invoking autoscan, , , autoconf, the autoconf manual}. -@end ifnothtml -@ifhtml -See @uref{http://www.delorie.com/gnu/docs/autoconf/autoconf_4.html, the -autoscan documentation}. -@end ifhtml - -Another handy tool for an existing body of code is @samp{ifnames}.

This includes -libraries such as @samp{bfd} and @samp{tcl}. These libraries are built -with the host compiler, and are linked into programs like the binutils -or gcc which run on the host. - -Target libraries are built with the target compiler. If gcc is present -in the source tree, then the target compiler is the gcc that is built -using the host compiler. Target libraries are libraries such as -@samp{newlib} and @samp{libstdc++}. These libraries are not linked into -the host programs, but are instead made available for use with programs -built with the target compiler. - -For the rest of this section, assume that gcc is present in the source -tree, so that it will be used to build the target libraries. - -There is a complication here. The configure process needs to know which -compiler you are going to use to build a tool; otherwise, the feature -tests will not work correctly. The Cygnus tree handles this by not -configuring the target libraries until the target compiler is built. In -order to permit everything to build using a single -@samp{configure}/@samp{make}, the configuration of the target libraries -is actually triggered during the make step. - -When the target libraries are configured, the @samp{--target} option is -not used. Instead, the @samp{--host} option is used with the argument -of the @samp{--target} option for the overall configuration. If no -@samp{--target} option was used for the overall configuration, the -@samp{--host} option will be passed with the output of the -@file{config.guess} shell script. Any @samp{--build} option is passed -down unchanged. - -This translation of configuration options is done because since the -target libraries are compiled with the target compiler, they are being -built in order to run on the target of the overall configuration. By -the definition of host, this means that their host system is the same as -the target system of the overall configuration. - -The same process is used for both a native configuration and a cross -configuration. Even when using a native configuration, the target -libraries will be configured and built using the newly built compiler. -This is particularly important for the C++ libraries, since there is no -reason to assume that the C++ compiler used to build the host tools (if -there even is one) uses the same ABI as the g++ compiler which will be -used to build the target libraries. - -There is one difference between a native configuration and a cross -configuration. In a native configuration, the target libraries are -normally configured and built as siblings of the host tools. In a cross -configuration, the target libraries are normally built in a subdirectory -whose name is the argument to @samp{--target}. This is mainly for -historical reasons. - -To summarize, running @samp{configure} in the Cygnus tree configures all -the host libraries and tools, but does not configure any of the target -libraries. Running @samp{make} then does the following steps: - -@itemize @bullet -@item -Build the host libraries. -@item -Build the host programs, including gcc. Note that we call gcc both a -host program (since it runs on the host) and a target compiler (since it -generates code for the target). -@item -Using the newly built target compiler, configure the target libraries. -@item -Build the target libraries. -@end itemize - -The steps need not be done in precisely this order, since they are -actually controlled by @file{Makefile} targets. - -@node Target Library Configure Scripts -@subsection Target Library Configure Scripts - -There are a few things you must know in order to write a configure -script for a target library. This is just a quick sketch, and beginners -shouldn't worry if they don't follow everything here. - -The target libraries are configured and built using a newly built target -compiler. There may not be any startup files or libraries for this -target compiler. In fact, those files will probably be built as part of -some target library, which naturally means that they will not exist when -your target library is configured. - -This means that the configure script for a target library may not use -any test which requires doing a link. This unfortunately includes many -useful autoconf macros, such as @samp{AC_CHECK_FUNCS}. autoconf macros -which do a compile but not a link, such as @samp{AC_CHECK_HEADERS}, may -be used. - -This is a severe restriction, but normally not a fatal one, as target -libraries can often assume the presence of other target libraries, and -thus know which functions will be available. - -As of this writing, the autoconf macro @samp{AC_PROG_CC} does a link to -make sure that the compiler works. This may fail in a target library, -so target libraries must use a different set of macros to locate the -compiler. See the @file{configure.in} file in a directory like -@file{libiberty} or @file{libgloss} for an example. - -As noted in the previous section, target libraries are sometimes built -in directories which are siblings to the host tools, and are sometimes -built in a subdirectory. The @samp{--with-target-subdir} configure -option will be passed when the library is configured. Its value will be -an empty string if the target library is a sibling. Its value will be -the name of the subdirectory if the target library is in a subdirectory. - -If the overall build is not a native build (i.e., the overall configure -used the @samp{--target} option), then the library will be configured -with the @samp{--with-cross-host} option. The value of this option will -be the host system of the overall build. Recall that the host system of -the library will be the target of the overall build. If the overall -build is a native build, the @samp{--with-cross-host} option will not be -used. - -A library which can be built both standalone and as a target library may -want to install itself into different directories depending upon the -case. When built standalone, or when built native, the library should -be installed in @samp{$(libdir)}. When built as a target library which -is not native, the library should be installed in @samp{$(tooldir)/lib}. -The @samp{--with-cross-host} option may be used to distinguish these -cases. - -This same test of @samp{--with-cross-host} may be used to see whether it -is OK to use link tests in the configure script. If the -@samp{--with-cross-host} option is not used, then the library is being -built either standalone or native, and a link should work. - -@node Make Targets in Cygnus Tree -@subsection Make Targets in Cygnus Tree - -The top level @file{Makefile} in the Cygnus tree defines targets for -every known subdirectory. - -For every subdirectory @var{dir} which holds a host library or program, -the @file{Makefile} target @samp{all-@var{dir}} will build that library -or program. - -There are dependencies among host tools.

It means that -there are targets for both @samp{all-libiberty} and -@samp{all-target-libiberty}. - -In a native configuration, when target libraries are not built in a -subdirectory, the same objects are normally used as both the host build -and the target build. This is normally OK, since libiberty contains -only C code, and in a native configuration the results of the host -compiler and the target compiler are normally interoperable. - -Irix 6 is again an exception here, since the SGI native compiler -defaults to using the @samp{O32} ABI, and gcc defaults to using the -@samp{N32} ABI.

The two cases are separate because -it isn't always necessary to regenerate all the files after running -@samp{config.status --recheck}. The @file{Makefile} targets generated -by automake will use the environment variables @samp{CONFIG_FILES} and -@samp{CONFIG_HEADERS} to only regenerate files as they are needed. - -@item What is the Cygnus tree? -The Cygnus tree is used for various packages including gdb, the GNU -binutils, and egcs. It is also, of course, used for Cygnus releases. -It is the build system which was developed at Cygnus, using the Cygnus -configure script. It permits building many different packages with a -single configure and make. The configure scripts in the tree are being -converted to autoconf, but the general build structure remains intact. - -@item Why do I have to keep rebuilding and reinstalling the tools? -I know, it's a pain. Unfortunately, there are bugs in the tools -themselves which need to be fixed, and each time that happens everybody -who uses the tools need to reinstall new versions of them. I don't know -if there is going to be a clever fix until the tools stabilize. - -@item Why not just have a Cygnus tree @samp{make} target to update the tools? -The tools unfortunately need to be installed before they can be used. -That means that they must be built using an appropriate prefix, and it -seems unwise to assume that every configuration uses an appropriate -prefix. It might be possible to make them work in place, or it might be -possible to install them in some subdirectory; so far these approaches -have not been implemented. -@end table - -@node Index -@unnumbered Index - -@printindex cp - -@contents -@bye diff --git a/contrib/binutils/etc/make-stds.texi b/contrib/binutils/etc/make-stds.texi deleted file mode 100644 index 2149764b8e9ce..0000000000000 --- a/contrib/binutils/etc/make-stds.texi +++ /dev/null @@ -1,914 +0,0 @@ -@comment This file is included by both standards.texi and make.texinfo. -@comment It was broken out of standards.texi on 1/6/93 by roland. - -@node Makefile Conventions -@chapter Makefile Conventions -@comment standards.texi does not print an index, but make.texinfo does. -@cindex makefile, conventions for -@cindex conventions for makefiles -@cindex standards for makefiles - -This -@ifinfo -node -@end ifinfo -@iftex -@ifset CODESTD -section -@end ifset -@ifclear CODESTD -chapter -@end ifclear -@end iftex -describes conventions for writing the Makefiles for GNU programs. - -@menu -* Makefile Basics:: General Conventions for Makefiles -* Utilities in Makefiles:: Utilities in Makefiles -* Command Variables:: Variables for Specifying Commands -* Directory Variables:: Variables for Installation Directories -* Standard Targets:: Standard Targets for Users -* Install Command Categories:: Three categories of commands in the `install' - rule: normal, pre-install and post-install. -@end menu - -@node Makefile Basics -@section General Conventions for Makefiles - -Every Makefile should contain this line: - -@example -SHELL = /bin/sh -@end example - -@noindent -to avoid trouble on systems where the @code{SHELL} variable might be -inherited from the environment.

Without one of these prefixes, the current search -path is used. - -The distinction between @file{./} (the @dfn{build directory}) and -@file{$(srcdir)/} (the @dfn{source directory}) is important because -users can build in a separate directory using the @samp{--srcdir} option -to @file{configure}.

Here are some of the programs we -mean: - -@example -ar bison cc flex install ld ldconfig lex -make makeinfo ranlib texi2dvi yacc -@end example - -Use the following @code{make} variables to run those programs: - -@example -$(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LDCONFIG) $(LEX) -$(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC) -@end example - -When you use @code{ranlib} or @code{ldconfig}, you should make sure -nothing bad happens if the system does not have the program in question. -Arrange to ignore an error from that command, and print a message before -the command to tell the user that failure of this command does not mean -a problem. (The Autoconf @samp{AC_PROG_RANLIB} macro can help with -this.) - -If you use symbolic links, you should implement a fallback for systems -that don't have symbolic links. - -Additional utilities that can be used via Make variables are: - -@example -chgrp chmod chown mknod -@end example - -It is ok to use other utilities in Makefile portions (or scripts) -intended only for particular systems where you know those utilities -exist. - -@node Command Variables -@section Variables for Specifying Commands - -Makefiles should provide variables for overriding certain commands, options, -and so on. - -In particular, you should run most utility programs via variables. -Thus, if you use Bison, have a variable named @code{BISON} whose default -value is set with @samp{BISON = bison}, and refer to it with -@code{$(BISON)} whenever you need to use Bison. - -File management utilities such as @code{ln}, @code{rm}, @code{mv}, and -so on, need not be referred to through variables in this way, since users -don't need to replace them with other programs. - -Each program-name variable should come with an options variable that is -used to supply options to the program. Append @samp{FLAGS} to the -program-name variable name to get the options variable name---for -example, @code{BISONFLAGS}. (The names @code{CFLAGS} for the C -compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are -exceptions to this rule, but we keep them because they are standard.) -Use @code{CPPFLAGS} in any compilation command that runs the -preprocessor, and use @code{LDFLAGS} in any compilation command that -does linking as well as in any direct use of @code{ld}. - -If there are C compiler options that @emph{must} be used for proper -compilation of certain files, do not include them in @code{CFLAGS}. -Users expect to be able to specify @code{CFLAGS} freely themselves. -Instead, arrange to pass the necessary options to the C compiler -independently of @code{CFLAGS}, by writing them explicitly in the -compilation commands or by defining an implicit rule, like this: - -@smallexample -CFLAGS = -g -ALL_CFLAGS = -I. $(CFLAGS) -.c.o: - $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $< -@end smallexample - -Do include the @samp{-g} option in @code{CFLAGS}, because that is not -@emph{required} for proper compilation. You can consider it a default -that is only recommended. If the package is set up so that it is -compiled with GCC by default, then you might as well include @samp{-O} -in the default value of @code{CFLAGS} as well. - -Put @code{CFLAGS} last in the compilation command, after other variables -containing compiler options, so the user can use @code{CFLAGS} to -override the others. - -@code{CFLAGS} should be used in every invocation of the C compiler, -both those which do compilation and those which do linking. - -Every Makefile should define the variable @code{INSTALL}, which is the -basic command for installing a file into the system. - -Every Makefile should also define the variables @code{INSTALL_PROGRAM} -and @code{INSTALL_DATA}. (The default for each of these should be -@code{$(INSTALL)}.) Then it should use those variables as the commands -for actual installation, for executables and nonexecutables -respectively. Use these variables as follows: - -@example -$(INSTALL_PROGRAM) foo $(bindir)/foo -$(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a -@end example - -Optionally, you may prepend the value of @code{DESTDIR} to the target -filename. Doing this allows the installer to create a snapshot of the -installation to be copied onto the real target filesystem later. Do not -set the value of @code{DESTDIR} in your Makefile, and do not include it -in any installed files. With support for @code{DESTDIR}, the above -examples become: - -@example -$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo -$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a -@end example - -@noindent -Always use a file name, not a directory name, as the second argument of -the installation commands.

This includes the directories -specified as the values of the variables @code{prefix} and -@code{exec_prefix}, as well as all subdirectories that are needed. -One way to do this is by means of an @code{installdirs} target -as described below. - -Use @samp{-} before any command for installing a man page, so that -@code{make} will ignore any errors.

The tar file should be -set up so that the file names in the tar file start with a subdirectory -name which is the name of the package it is a distribution for. This -name can include the version number. - -For example, the distribution tar file of GCC version 1.40 unpacks into -a subdirectory named @file{gcc-1.40}. - -The easiest way to do this is to create a subdirectory appropriately -named, use @code{ln} or @code{cp} to install the proper files in it, and -then @code{tar} that subdirectory. - -Compress the tar file file with @code{gzip}. For example, the actual -distribution file for GCC version 1.40 is called @file{gcc-1.40.tar.gz}. - -The @code{dist} target should explicitly depend on all non-source files -that are in the distribution, to make sure they are up to date in the -distribution. -@ifset CODESTD -@xref{Releases, , Making Releases}. -@end ifset -@ifclear CODESTD -@xref{Releases, , Making Releases, standards, GNU Coding Standards}. -@end ifclear - -@item check -Perform self-tests (if any).

They may not alter any files except the ones that come entirely -from the package they belong to. - -Pre-installation and post-installation commands may alter other files; -in particular, they can edit global configuration files or data bases. - -Pre-installation commands are typically executed before the normal -commands, and post-installation commands are typically run after the -normal commands. - -The most common use for a post-installation command is to run -@code{install-info}. This cannot be done with a normal command, since -it alters a file (the Info directory) which does not come entirely and -solely from the package being installed. It is a post-installation -command because it needs to be done after the normal command which -installs the package's Info files. - -Most programs don't need any pre-installation commands, but we have the -feature just in case it is needed. - -To classify the commands in the @code{install} rule into these three -categories, insert @dfn{category lines} among them. A category line -specifies the category for the commands that follow. - -A category line consists of a tab and a reference to a special Make -variable, plus an optional comment at the end. There are three -variables you can use, one for each category; the variable name -specifies the category. Category lines are no-ops in ordinary execution -because these three Make variables are normally undefined (and you -@emph{should not} define them in the makefile). - -Here are the three possible category lines, each with a comment that -explains what it means: - -@smallexample - $(PRE_INSTALL) # @r{Pre-install commands follow.} - $(POST_INSTALL) # @r{Post-install commands follow.} - $(NORMAL_INSTALL) # @r{Normal commands follow.} -@end smallexample - -If you don't use a category line at the beginning of the @code{install} -rule, all the commands are classified as normal until the first category -line. If you don't use any category lines, all the commands are -classified as normal. - -These are the category lines for @code{uninstall}: - -@smallexample - $(PRE_UNINSTALL) # @r{Pre-uninstall commands follow.} - $(POST_UNINSTALL) # @r{Post-uninstall commands follow.} - $(NORMAL_UNINSTALL) # @r{Normal commands follow.} -@end smallexample - -Typically, a pre-uninstall command would be used for deleting entries -from the Info directory. - -If the @code{install} or @code{uninstall} target has any dependencies -which act as subroutines of installation, then you should start -@emph{each} dependency's commands with a category line, and start the -main target's commands with a category line also. This way, you can -ensure that each command is placed in the right category regardless of -which of the dependencies actually run. - -Pre-installation and post-installation commands should not run any -programs except for these: - -@example -[ basename bash cat chgrp chmod chown cmp cp dd diff echo -egrep expand expr false fgrep find getopt grep gunzip gzip -hostname install install-info kill ldconfig ln ls md5sum -mkdir mkfifo mknod mv printenv pwd rm rmdir sed sort tee -test touch true uname xargs yes -@end example - -@cindex binary packages -The reason for distinguishing the commands in this way is for the sake -of making binary packages. Typically a binary package contains all the -executables and other files that need to be installed, and has its own -method of installing them---so it does not need to run the normal -installation commands. But installing the binary package does need to -execute the pre-installation and post-installation commands. - -Programs to build binary packages work by extracting the -pre-installation and post-installation commands. Here is one way of -extracting the pre-installation commands: - -@smallexample -make -n install -o all \ - PRE_INSTALL=pre-install \ - POST_INSTALL=post-install \ - NORMAL_INSTALL=normal-install \ - | gawk -f pre-install.awk -@end smallexample - -@noindent -where the file @file{pre-install.awk} could contain this: - -@smallexample -$0 ~ /^\t[ \t]*(normal_install|post_install)[ \t]*$/ @{on = 0@} -on @{print $0@} -$0 ~ /^\t[ \t]*pre_install[ \t]*$/ @{on = 1@} -@end smallexample - -The resulting file of pre-installation commands is executed as a shell -script as part of installing the binary package. diff --git a/contrib/binutils/etc/standards.texi b/contrib/binutils/etc/standards.texi deleted file mode 100644 index 910bf8b0479e3..0000000000000 --- a/contrib/binutils/etc/standards.texi +++ /dev/null @@ -1,3093 +0,0 @@ -\input texinfo @c -*-texinfo-*- -@c %**start of header -@setfilename standards.info -@settitle GNU Coding Standards -@c This date is automagically updated when you save this file: -@set lastupdate March 13, 1998 -@c %**end of header - -@ifinfo -@format -START-INFO-DIR-ENTRY -* Standards: (standards).

Their purpose is to make the GNU system clean, -consistent, and easy to install. This document can also be read as a -guide to writing portable, robust and reliable programs. It focuses on -programs written in C, but many of the rules and principles are useful -even if you write in another programming language. The rules often -state reasons for writing in a certain way. - -Corrections or suggestions for this document should be sent to -@email{gnu@@gnu.org}. If you make a suggestion, please include a -suggested new wording for it; our time is limited. We prefer a context -diff to the @file{standards.texi} or @file{make-stds.texi} files, but if -you don't have those files, please mail your suggestion anyway. - -This release of the GNU Coding Standards was last updated -@value{lastupdate}. - -@node Intellectual Property -@chapter Keeping Free Software Free - -This @value{CHAPTER} discusses how you can make sure that GNU software -remains unencumbered. - -@menu -* Reading Non-Free Code:: Referring to Proprietary Programs -* Contributions:: Accepting Contributions -@end menu - -@node Reading Non-Free Code -@section Referring to Proprietary Programs - -Don't in any circumstances refer to Unix source code for or during -your work on GNU! (Or to any other proprietary programs.) - -If you have a vague recollection of the internals of a Unix program, -this does not absolutely mean you can't write an imitation of it, but -do try to organize the imitation internally along different lines, -because this is likely to make the details of the Unix version -irrelevant and dissimilar to your results. - -For example, Unix utilities were generally optimized to minimize -memory use; if you go for speed instead, your program will be very -different. You could keep the entire input file in core and scan it -there instead of using stdio. Use a smarter algorithm discovered more -recently than the Unix program. Eliminate use of temporary files. Do -it in one pass instead of two (we did this in the assembler). - -Or, on the contrary, emphasize simplicity instead of speed. For some -applications, the speed of today's computers makes simpler algorithms -adequate. - -Or go for generality. For example, Unix programs often have static -tables or fixed-size strings, which make for arbitrary limits; use -dynamic allocation instead. Make sure your program handles NULs and -other funny characters in the input files. Add a programming language -for extensibility and write part of the program in that language. - -Or turn some parts of the program into independently usable libraries. -Or use a simple garbage collector instead of tracking precisely when -to free memory, or use a new GNU facility such as obstacks. - - -@node Contributions -@section Accepting Contributions - -If someone else sends you a piece of code to add to the program you are -working on, we need legal papers to use it---the same sort of legal -papers we will need to get from you. @emph{Each} significant -contributor to a program must sign some sort of legal papers in order -for us to have clear title to the program. The main author alone is not -enough. - -So, before adding in any contributions from other people, please tell -us, so we can arrange to get the papers. Then wait until we tell you -that we have received the signed papers, before you actually use the -contribution. - -This applies both before you release the program and afterward. If -you receive diffs to fix a bug, and they make significant changes, we -need legal papers for that change. - -This also applies to comments and documentation files. For copyright -law, comments and code are just text. Copyright applies to all kinds of -text, so we need legal papers for all kinds. - -You don't need papers for changes of a few lines here or there, since -they are not significant for copyright purposes. Also, you don't need -papers if all you get from the suggestion is some ideas, not actual code -which you use. For example, if you write a different solution to the -problem, you don't need to get papers. - -We know this is frustrating; it's frustrating for us as well. But if -you don't wait, you are going out on a limb---for example, what if the -contributor's employer won't sign a disclaimer? You might have to take -that code out again! - -The very worst thing is if you forget to tell us about the other -contributor. We could be very embarrassed in court some day as a -result. - -We have more detailed advice for maintainers of programs; if you have -reached the stage of actually maintaining a program for GNU (whether -released or not), please ask us for a copy. - -@node Design Advice -@chapter General Program Design - -This @value{CHAPTER} discusses some of the issues you should take into -account when designing your program. - -@menu -* Compatibility:: Compatibility with other implementations -* Using Extensions:: Using non-standard features -* ANSI C:: Using ANSI C features -* Source Language:: Using languages other than C -@end menu - -@node Compatibility -@section Compatibility with Other Implementations - -With occasional exceptions, utility programs and libraries for GNU -should be upward compatible with those in Berkeley Unix, and upward -compatible with @sc{ansi} C if @sc{ansi} C specifies their behavior, and -upward compatible with @sc{POSIX} if @sc{POSIX} specifies their -behavior. - -When these standards conflict, it is useful to offer compatibility -modes for each of them. - -@sc{ansi} C and @sc{POSIX} prohibit many kinds of extensions. Feel free -to make the extensions anyway, and include a @samp{--ansi}, -@samp{--posix}, or @samp{--compatible} option to turn them off. -However, if the extension has a significant chance of breaking any real -programs or scripts, then it is not really upward compatible. Try to -redesign its interface. - -Many GNU programs suppress extensions that conflict with POSIX if the -environment variable @code{POSIXLY_CORRECT} is defined (even if it is -defined with a null value). Please make your program recognize this -variable if appropriate. - -When a feature is used only by users (not by programs or command -files), and it is done poorly in Unix, feel free to replace it -completely with something totally different and better. (For example, -@code{vi} is replaced with Emacs.) But it is nice to offer a compatible -feature as well. (There is a free @code{vi} clone, so we offer it.) - -Additional useful features not in Berkeley Unix are welcome. - -@node Using Extensions -@section Using Non-standard Features - -Many GNU facilities that already exist support a number of convenient -extensions over the comparable Unix facilities. Whether to use these -extensions in implementing your program is a difficult question. - -On the one hand, using the extensions can make a cleaner program. -On the other hand, people will not be able to build the program -unless the other GNU tools are available. This might cause the -program to work on fewer kinds of machines. - -With some extensions, it might be easy to provide both alternatives. -For example, you can define functions with a ``keyword'' @code{INLINE} -and define that as a macro to expand into either @code{inline} or -nothing, depending on the compiler. - -In general, perhaps it is best not to use the extensions if you can -straightforwardly do without them, but to use the extensions if they -are a big improvement. - -An exception to this rule are the large, established programs (such as -Emacs) which run on a great variety of systems. Such programs would -be broken by use of GNU extensions. - -Another exception is for programs that are used as part of -compilation: anything that must be compiled with other compilers in -order to bootstrap the GNU compilation facilities. If these require -the GNU compiler, then no one can compile them without having them -installed already. That would be no good. - -@node ANSI C -@section @sc{ansi} C and pre-@sc{ansi} C - -Do not ever use the ``trigraph'' feature of @sc{ansi} C. - -@sc{ansi} C is widespread enough now that it is ok to write new programs -that use @sc{ansi} C features (and therefore will not work in -non-@sc{ansi} compilers). And if a program is already written in -@sc{ansi} C, there's no need to convert it to support non-@sc{ansi} -compilers. - -However, it is easy to support non-@sc{ansi} compilers in most programs, -so you might still consider doing so when you write a program. Instead -of writing function definitions in @sc{ansi} prototype form, - -@example -int -foo (int x, int y) -@dots{} -@end example - -@noindent -write the definition in pre-@sc{ansi} style like this, - -@example -int -foo (x, y) - int x, y; -@dots{} -@end example - -@noindent -and use a separate declaration to specify the argument prototype: - -@example -int foo (int, int); -@end example - -You need such a declaration anyway, in a header file, to get the benefit -of @sc{ansi} C prototypes in all the files where the function is called. -And once you have it, you lose nothing by writing the function -definition in the pre-@sc{ansi} style. - -If you don't know non-@sc{ansi} C, there's no need to learn it; just -write in @sc{ansi} C. - -@node Source Language -@section Using Languages Other Than C - -Using a language other than C is like using a non-standard feature: it -will cause trouble for users. Even if GCC supports the other language, -users may find it inconvenient to have to install the compiler for that -other language in order to build your program. For example, if you -write your program in C++, people will have to install the C++ compiler -in order to compile your program. Thus, it is better if you write in C. - -But there are three situations when there is no disadvantage in using -some other language: - -@itemize @bullet -@item -It is okay to use another language if your program contains an -interpreter for that language. - -For example, if your program links with GUILE, it is ok to write part of -the program in Scheme or another language supported by GUILE. - -@item -It is okay to use another language in a tool specifically intended for -use with that language. - -This is okay because the only people who want to build the tool will be -those who have installed the other language anyway. - -@item -If an application is of interest to a narrow community, then perhaps -it's not important if the application is inconvenient to install. -@end itemize - -C has one other advantage over C++ and other compiled languages: more -people know C, so more people will find it easy to read and modify the -program if it is written in C. - -@node Program Behavior -@chapter Program Behavior for All Programs - -This @value{CHAPTER} describes how to write robust software. It also -describes general standards for error messages, the command line interface, -and how libraries should behave. - -@menu -* Semantics:: Writing robust programs -* Libraries:: Library behavior -* Errors:: Formatting error messages -* User Interfaces:: Standards for command line interfaces -* Option Table:: Table of long options. -* Memory Usage:: When and how to care about memory needs -@end menu - -@node Semantics -@section Writing Robust Programs - -Avoid arbitrary limits on the length or number of @emph{any} data -structure, including file names, lines, files, and symbols, by allocating -all data structures dynamically. In most Unix utilities, ``long lines -are silently truncated''. This is not acceptable in a GNU utility. - -Utilities reading files should not drop NUL characters, or any other -nonprinting characters @emph{including those with codes above 0177}. The -only sensible exceptions would be utilities specifically intended for -interface to certain types of printers that can't handle those characters. - -Check every system call for an error return, unless you know you wish to -ignore errors. Include the system error text (from @code{perror} or -equivalent) in @emph{every} error message resulting from a failing -system call, as well as the name of the file if any and the name of the -utility. Just ``cannot open foo.c'' or ``stat failed'' is not -sufficient. - -Check every call to @code{malloc} or @code{realloc} to see if it -returned zero. Check @code{realloc} even if you are making the block -smaller; in a system that rounds block sizes to a power of 2, -@code{realloc} may get a different block if you ask for less space. - -In Unix, @code{realloc} can destroy the storage block if it returns -zero. GNU @code{realloc} does not have this bug: if it fails, the -original block is unchanged. Feel free to assume the bug is fixed. If -you wish to run your program on Unix, and wish to avoid lossage in this -case, you can use the GNU @code{malloc}. - -You must expect @code{free} to alter the contents of the block that was -freed. Anything you want to fetch from the block, you must fetch before -calling @code{free}. - -If @code{malloc} fails in a noninteractive program, make that a fatal -error. In an interactive program (one that reads commands from the -user), it is better to abort the command and return to the command -reader loop. This allows the user to kill other processes to free up -virtual memory, and then try the command again. - -Use @code{getopt_long} to decode arguments, unless the argument syntax -makes this unreasonable. - -When static storage is to be written in during program execution, use -explicit C code to initialize it. Reserve C initialized declarations -for data that will not be changed. -@c ADR: why? - -Try to avoid low-level interfaces to obscure Unix data structures (such -as file directories, utmp, or the layout of kernel memory), since these -are less likely to work compatibly. If you need to find all the files -in a directory, use @code{readdir} or some other high-level interface. -These will be supported compatibly by GNU. - -By default, the GNU system will provide the signal handling functions of -@sc{BSD} and of @sc{POSIX}. So GNU software should be written to use -these. - -In error checks that detect ``impossible'' conditions, just abort. -There is usually no point in printing any message. These checks -indicate the existence of bugs. Whoever wants to fix the bugs will have -to read the source code and run a debugger. So explain the problem with -comments in the source. The relevant data will be in variables, which -are easy to examine with the debugger, so there is no point moving them -elsewhere. - -Do not use a count of errors as the exit status for a program. -@emph{That does not work}, because exit status values are limited to 8 -bits (0 through 255). A single run of the program might have 256 -errors; if you try to return 256 as the exit status, the parent process -will see 0 as the status, and it will appear that the program succeeded. - -If you make temporary files, check the @code{TMPDIR} environment -variable; if that variable is defined, use the specified directory -instead of @file{/tmp}. - -@node Libraries -@section Library Behavior - -Try to make library functions reentrant. If they need to do dynamic -storage allocation, at least try to avoid any nonreentrancy aside from -that of @code{malloc} itself. - -Here are certain name conventions for libraries, to avoid name -conflicts. - -Choose a name prefix for the library, more than two characters long. -All external function and variable names should start with this -prefix. In addition, there should only be one of these in any given -library member. This usually means putting each one in a separate -source file. - -An exception can be made when two external symbols are always used -together, so that no reasonable program could use one without the -other; then they can both go in the same file. - -External symbols that are not documented entry points for the user -should have names beginning with @samp{_}. They should also contain -the chosen name prefix for the library, to prevent collisions with -other libraries. These can go in the same files with user entry -points if you like. - -Static functions and variables can be used as you like and need not -fit any naming convention. - -@node Errors -@section Formatting Error Messages - -Error messages from compilers should look like this: - -@example -@var{source-file-name}:@var{lineno}: @var{message} -@end example - -Error messages from other noninteractive programs should look like this: - -@example -@var{program}:@var{source-file-name}:@var{lineno}: @var{message} -@end example - -@noindent -when there is an appropriate source file, or like this: - -@example -@var{program}: @var{message} -@end example - -@noindent -when there is no relevant source file. - -In an interactive program (one that is reading commands from a -terminal), it is better not to include the program name in an error -message. The place to indicate which program is running is in the -prompt or with the screen layout. (When the same program runs with -input from a source other than a terminal, it is not interactive and -would do best to print error messages using the noninteractive style.) - -The string @var{message} should not begin with a capital letter when -it follows a program name and/or file name. Also, it should not end -with a period. - -Error messages from interactive programs, and other messages such as -usage messages, should start with a capital letter. But they should not -end with a period. - -@node User Interfaces -@section Standards for Command Line Interfaces - -Please don't make the behavior of a utility depend on the name used -to invoke it. It is useful sometimes to make a link to a utility -with a different name, and that should not change what it does. - -Instead, use a run time option or a compilation switch or both -to select among the alternate behaviors. - -Likewise, please don't make the behavior of the program depend on the -type of output device it is used with. Device independence is an -important principle of the system's design; do not compromise it -merely to save someone from typing an option now and then. - -If you think one behavior is most useful when the output is to a -terminal, and another is most useful when the output is a file or a -pipe, then it is usually best to make the default behavior the one that -is useful with output to a terminal, and have an option for the other -behavior. - -Compatibility requires certain programs to depend on the type of output -device. It would be disastrous if @code{ls} or @code{sh} did not do so -in the way all users expect. In some of these cases, we supplement the -program with a preferred alternate version that does not depend on the -output device type. For example, we provide a @code{dir} program much -like @code{ls} except that its default output format is always -multi-column format. - -It is a good idea to follow the @sc{POSIX} guidelines for the -command-line options of a program. The easiest way to do this is to use -@code{getopt} to parse them. Note that the GNU version of @code{getopt} -will normally permit options anywhere among the arguments unless the -special argument @samp{--} is used. This is not what @sc{POSIX} -specifies; it is a GNU extension. - -Please define long-named options that are equivalent to the -single-letter Unix-style options. We hope to make GNU more user -friendly this way. This is easy to do with the GNU function -@code{getopt_long}. - -One of the advantages of long-named options is that they can be -consistent from program to program. For example, users should be able -to expect the ``verbose'' option of any GNU program which has one, to be -spelled precisely @samp{--verbose}. To achieve this uniformity, look at -the table of common long-option names when you choose the option names -for your program (@pxref{Option Table}). - -It is usually a good idea for file names given as ordinary arguments to -be input files only; any output files would be specified using options -(preferably @samp{-o} or @samp{--output}). Even if you allow an output -file name as an ordinary argument for compatibility, try to provide an -option as another way to specify it. This will lead to more consistency -among GNU utilities, and fewer idiosyncracies for users to remember. - -All programs should support two standard options: @samp{--version} -and @samp{--help}. - -@table @code -@item --version -This option should direct the program to information about its name, -version, origin and legal status, all on standard output, and then exit -successfully. Other options and arguments should be ignored once this -is seen, and the program should not perform its normal function. - -The first line is meant to be easy for a program to parse; the version -number proper starts after the last space. In addition, it contains -the canonical name for this program, in this format: - -@example -GNU Emacs 19.30 -@end example - -@noindent -The program's name should be a constant string; @emph{don't} compute it -from @code{argv[0]}. The idea is to state the standard or canonical -name for the program, not its file name.

Use the same format for these lines as for -the first line. - -Please do not mention all of the libraries that the program uses ``just -for completeness''---that would produce a lot of unhelpful clutter. -Please mention library version numbers only if you find in practice that -they are very important to you in debugging. - -The following line, after the version number line or lines, should be a -copyright notice.

If -the program is covered by the GNU GPL, say so here. Also mention that -there is no warranty, to the extent permitted by law. - -It is ok to finish the output with a list of the major authors of the -program, as a way of giving credit. - -Here's an example of output that follows these rules: - -@smallexample -GNU Emacs 19.34.5 -Copyright (C) 1996 Free Software Foundation, Inc. -GNU Emacs comes with NO WARRANTY, -to the extent permitted by law. -You may redistribute copies of GNU Emacs -under the terms of the GNU General Public License. -For more information about these matters, -see the files named COPYING. -@end smallexample - -You should adapt this to your program, of course, filling in the proper -year, copyright holder, name of program, and the references to -distribution terms, and changing the rest of the wording as necessary. - -This copyright notice only needs to mention the most recent year in -which changes were made---there's no need to list the years for previous -versions' changes.

Other options and -arguments should be ignored once this is seen, and the program should -not perform its normal function. - -Near the end of the @samp{--help} option's output there should be a line -that says where to mail bug reports.

Several tools look -for open-braces in column zero to find the beginnings of C functions. -These tools will not work on code not formatted that way. - -It is also important for function definitions to start the name of the -function in column zero. This helps people to search for function -definitions, and may also help certain tools recognize them. Thus, -the proper format is this: - -@example -static char * -concat (s1, s2) /* Name starts in column zero here */ - char *s1, *s2; -@{ /* Open brace in column zero here */ - @dots{} -@} -@end example - -@noindent -or, if you want to use @sc{ansi} C, format the definition like this: - -@example -static char * -concat (char *s1, char *s2) -@{ - @dots{} -@} -@end example - -In @sc{ansi} C, if the arguments don't fit nicely on one line, -split it like this: - -@example -int -lots_of_args (int an_integer, long a_long, short a_short, - double a_double, float a_float) -@dots{} -@end example - -For the body of the function, we prefer code formatted like this: - -@example -if (x < foo (y, z)) - haha = bar[4] + 5; -else - @{ - while (z) - @{ - haha += foo (z, z); - z--; - @} - return ++x + bar (); - @} -@end example - -We find it easier to read a program when it has spaces before the -open-parentheses and after the commas. Especially after the commas. - -When you split an expression into multiple lines, split it -before an operator, not after one. Here is the right way: - -@example -if (foo_this_is_long && bar > win (x, y, z) - && remaining_condition) -@end example - -Try to avoid having two operators of different precedence at the same -level of indentation. For example, don't write this: - -@example -mode = (inmode[j] == VOIDmode - || GET_MODE_SIZE (outmode[j]) > GET_MODE_SIZE (inmode[j]) - ? outmode[j] : inmode[j]); -@end example - -Instead, use extra parentheses so that the indentation shows the nesting: - -@example -mode = ((inmode[j] == VOIDmode - || (GET_MODE_SIZE (outmode[j]) > GET_MODE_SIZE (inmode[j]))) - ? outmode[j] : inmode[j]); -@end example - -Insert extra parentheses so that Emacs will indent the code properly. -For example, the following indentation looks nice if you do it by hand, -but Emacs would mess it up: - -@example -v = rup->ru_utime.tv_sec*1000 + rup->ru_utime.tv_usec/1000 - + rup->ru_stime.tv_sec*1000 + rup->ru_stime.tv_usec/1000; -@end example - -But adding a set of parentheses solves the problem: - -@example -v = (rup->ru_utime.tv_sec*1000 + rup->ru_utime.tv_usec/1000 - + rup->ru_stime.tv_sec*1000 + rup->ru_stime.tv_usec/1000); -@end example - -Format do-while statements like this: - -@example -do - @{ - a = foo (a); - @} -while (a > 0); -@end example - -Please use formfeed characters (control-L) to divide the program into -pages at logical places (but not within a function). It does not matter -just how long the pages are, since they do not have to fit on a printed -page. The formfeeds should appear alone on lines by themselves. - - -@node Comments -@section Commenting Your Work - -Every program should start with a comment saying briefly what it is for. -Example: @samp{fmt - filter for simple filling of text}. - -Please write the comments in a GNU program in English, because English -is the one language that nearly all programmers in all countries can -read. If you do not write English well, please write comments in -English as well as you can, then ask other people to help rewrite them. -If you can't write comments in English, please find someone to work with -you and translate your comments into English. - -Please put a comment on each function saying what the function does, -what sorts of arguments it gets, and what the possible values of -arguments mean and are used for. It is not necessary to duplicate in -words the meaning of the C argument declarations, if a C type is being -used in its customary fashion. If there is anything nonstandard about -its use (such as an argument of type @code{char *} which is really the -address of the second character of a string, not the first), or any -possible values that would not work the way one would expect (such as, -that strings containing newlines are not guaranteed to work), be sure -to say so. - -Also explain the significance of the return value, if there is one. - -Please put two spaces after the end of a sentence in your comments, so -that the Emacs sentence commands will work. Also, please write -complete sentences and capitalize the first word. If a lower-case -identifier comes at the beginning of a sentence, don't capitalize it! -Changing the spelling makes it a different identifier. If you don't -like starting a sentence with a lower case letter, write the sentence -differently (e.g., ``The identifier lower-case is @dots{}''). - -The comment on a function is much clearer if you use the argument -names to speak about the argument values. The variable name itself -should be lower case, but write it in upper case when you are speaking -about the value rather than the variable itself. Thus, ``the inode -number NODE_NUM'' rather than ``an inode''. - -There is usually no purpose in restating the name of the function in -the comment before it, because the reader can see that for himself. -There might be an exception when the comment is so long that the function -itself would be off the bottom of the screen. - -There should be a comment on each static variable as well, like this: - -@example -/* Nonzero means truncate lines in the display; - zero means continue them. */ -int truncate_lines; -@end example - -Every @samp{#endif} should have a comment, except in the case of short -conditionals (just a few lines) that are not nested. The comment should -state the condition of the conditional that is ending, @emph{including -its sense}. @samp{#else} should have a comment describing the condition -@emph{and sense} of the code that follows. For example: - -@example -@group -#ifdef foo - @dots{} -#else /* not foo */ - @dots{} -#endif /* not foo */ -@end group -@group -#ifdef foo - @dots{} -#endif /* foo */ -@end group -@end example - -@noindent -but, by contrast, write the comments this way for a @samp{#ifndef}: - -@example -@group -#ifndef foo - @dots{} -#else /* foo */ - @dots{} -#endif /* foo */ -@end group -@group -#ifndef foo - @dots{} -#endif /* not foo */ -@end group -@end example - -@node Syntactic Conventions -@section Clean Use of C Constructs - -Please explicitly declare all arguments to functions. -Don't omit them just because they are @code{int}s. - -Declarations of external functions and functions to appear later in the -source file should all go in one place near the beginning of the file -(somewhere before the first function definition in the file), or else -should go in a header file. Don't put @code{extern} declarations inside -functions. - -It used to be common practice to use the same local variables (with -names like @code{tem}) over and over for different values within one -function. Instead of doing this, it is better declare a separate local -variable for each distinct purpose, and give it a name which is -meaningful. This not only makes programs easier to understand, it also -facilitates optimization by good compilers. You can also move the -declaration of each local variable into the smallest scope that includes -all its uses. This makes the program even cleaner. - -Don't use local variables or parameters that shadow global identifiers. - -Don't declare multiple variables in one declaration that spans lines. -Start a new declaration on each line, instead. For example, instead -of this: - -@example -@group -int foo, - bar; -@end group -@end example - -@noindent -write either this: - -@example -int foo, bar; -@end example - -@noindent -or this: - -@example -int foo; -int bar; -@end example - -@noindent -(If they are global variables, each should have a comment preceding it -anyway.) - -When you have an @code{if}-@code{else} statement nested in another -@code{if} statement, always put braces around the @code{if}-@code{else}. -Thus, never write like this: - -@example -if (foo) - if (bar) - win (); - else - lose (); -@end example - -@noindent -always like this: - -@example -if (foo) - @{ - if (bar) - win (); - else - lose (); - @} -@end example - -If you have an @code{if} statement nested inside of an @code{else} -statement, either write @code{else if} on one line, like this, - -@example -if (foo) - @dots{} -else if (bar) - @dots{} -@end example - -@noindent -with its @code{then}-part indented like the preceding @code{then}-part, -or write the nested @code{if} within braces like this: - -@example -if (foo) - @dots{} -else - @{ - if (bar) - @dots{} - @} -@end example - -Don't declare both a structure tag and variables or typedefs in the -same declaration. Instead, declare the structure tag separately -and then use it to declare the variables or typedefs. - -Try to avoid assignments inside @code{if}-conditions. For example, -don't write this: - -@example -if ((foo = (char *) malloc (sizeof *foo)) == 0) - fatal ("virtual memory exhausted"); -@end example - -@noindent -instead, write this: - -@example -foo = (char *) malloc (sizeof *foo); -if (foo == 0) - fatal ("virtual memory exhausted"); -@end example - -Don't make the program ugly to placate @code{lint}. Please don't insert any -casts to @code{void}. Zero without a cast is perfectly fine as a null -pointer constant, except when calling a varargs function. - -@node Names -@section Naming Variables and Functions - -The names of global variables and functions in a program serve as -comments of a sort. So don't choose terse names---instead, look for -names that give useful information about the meaning of the variable or -function. In a GNU program, names should be English, like other -comments. - -Local variable names can be shorter, because they are used only within -one context, where (presumably) comments explain their purpose. - -Please use underscores to separate words in a name, so that the Emacs -word commands can be useful within them. Stick to lower case; reserve -upper case for macros and @code{enum} constants, and for name-prefixes -that follow a uniform convention. - -For example, you should use names like @code{ignore_space_change_flag}; -don't use names like @code{iCantReadThis}. - -Variables that indicate whether command-line options have been -specified should be named after the meaning of the option, not after -the option-letter. A comment should state both the exact meaning of -the option and its letter. For example, - -@example -@group -/* Ignore changes in horizontal whitespace (-b). */ -int ignore_space_change_flag; -@end group -@end example - -When you want to define names with constant integer values, use -@code{enum} rather than @samp{#define}. GDB knows about enumeration -constants. - -Use file names of 14 characters or less, to avoid creating gratuitous -problems on older System V systems. You can use the program -@code{doschk} to test for this. @code{doschk} also tests for potential -name conflicts if the files were loaded onto an MS-DOS file -system---something you may or may not care about. - -@node System Portability -@section Portability between System Types - -In the Unix world, ``portability'' refers to porting to different Unix -versions. For a GNU program, this kind of portability is desirable, but -not paramount. - -The primary purpose of GNU software is to run on top of the GNU kernel, -compiled with the GNU C compiler, on various types of @sc{cpu}. The -amount and kinds of variation among GNU systems on different @sc{cpu}s -will be comparable to the variation among Linux-based GNU systems or -among BSD systems today. So the kinds of portability that are absolutely -necessary are quite limited. - -But many users do run GNU software on non-GNU Unix or Unix-like systems. -So supporting a variety of Unix-like systems is desirable, although not -paramount. - -The easiest way to achieve portability to most Unix-like systems is to -use Autoconf. It's unlikely that your program needs to know more -information about the host platform than Autoconf can provide, simply -because most of the programs that need such knowledge have already been -written. - -Avoid using the format of semi-internal data bases (e.g., directories) -when there is a higher-level alternative (@code{readdir}). - -As for systems that are not like Unix, such as MSDOS, Windows, the -Macintosh, VMS, and MVS, supporting them is usually so much work that it -is better if you don't. - -The planned GNU kernel is not finished yet, but you can tell which -facilities it will provide by looking at the GNU C Library Manual. The -GNU kernel is based on Mach, so the features of Mach will also be -available. However, if you use Mach features, you'll probably have -trouble debugging your program today. - -@node CPU Portability -@section Portability between @sc{cpu}s - -Even GNU systems will differ because of differences among @sc{cpu} -types---for example, difference in byte ordering and alignment -requirements. It is absolutely essential to handle these differences. -However, don't make any effort to cater to the possibility that an -@code{int} will be less than 32 bits. We don't support 16-bit machines -in GNU. - -Don't assume that the address of an @code{int} object is also the -address of its least-significant byte. This is false on big-endian -machines. Thus, don't make the following mistake: - -@example -int c; -@dots{} -while ((c = getchar()) != EOF) - write(file_descriptor, &c, 1); -@end example - -When calling functions, you need not worry about the difference between -pointers of various types, or between pointers and integers. On most -machines, there's no difference anyway. As for the few machines where -there is a difference, all of them support @sc{ansi} C, so you can use -prototypes (conditionalized to be active only in @sc{ansi} C) to make -the code work on those systems. - -In certain cases, it is ok to pass integer and pointer arguments -indiscriminately to the same function, and use no prototype on any -system. For example, many GNU programs have error-reporting functions -that pass their arguments along to @code{printf} and friends: - -@example -error (s, a1, a2, a3) - char *s; - int a1, a2, a3; -@{ - fprintf (stderr, "error: "); - fprintf (stderr, s, a1, a2, a3); -@} -@end example - -@noindent -In practice, this works on all machines, and it is much simpler than any -``correct'' alternative. Be sure @emph{not} to use a prototype -for such functions. - -However, avoid casting pointers to integers unless you really need to. -These assumptions really reduce portability, and in most programs they -are easy to avoid. In the cases where casting pointers to integers is -essential---such as, a Lisp interpreter which stores type information as -well as an address in one word---it is ok to do so, but you'll have to -make explicit provisions to handle different word sizes. - -@node System Functions -@section Calling System Functions - -C implementations differ substantially. @sc{ansi} C reduces but does not -eliminate the incompatibilities; meanwhile, many users wish to compile -GNU software with pre-@sc{ansi} compilers. This chapter gives -recommendations for how to use the more or less standard C library -functions to avoid unnecessary loss of portability. - -@itemize @bullet -@item -Don't use the value of @code{sprintf}. It returns the number of -characters written on some systems, but not on all systems. - -@item -@code{main} should be declared to return type @code{int}. It should -terminate either by calling @code{exit} or by returning the integer -status code; make sure it cannot ever return an undefined value. - -@item -Don't declare system functions explicitly. - -Almost any declaration for a system function is wrong on some system. -To minimize conflicts, leave it to the system header files to declare -system functions. If the headers don't declare a function, let it -remain undeclared. - -While it may seem unclean to use a function without declaring it, in -practice this works fine for most system library functions on the -systems where this really happens; thus, the disadvantage is only -theoretical. By contrast, actual declarations have frequently caused -actual conflicts. - -@item -If you must declare a system function, don't specify the argument types. -Use an old-style declaration, not an @sc{ansi} prototype. The more you -specify about the function, the more likely a conflict. - -@item -In particular, don't unconditionally declare @code{malloc} or -@code{realloc}. - -Most GNU programs use those functions just once, in functions -conventionally named @code{xmalloc} and @code{xrealloc}. These -functions call @code{malloc} and @code{realloc}, respectively, and -check the results. - -Because @code{xmalloc} and @code{xrealloc} are defined in your program, -you can declare them in other files without any risk of type conflict. - -On most systems, @code{int} is the same length as a pointer; thus, the -calls to @code{malloc} and @code{realloc} work fine. For the few -exceptional systems (mostly 64-bit machines), you can use -@strong{conditionalized} declarations of @code{malloc} and -@code{realloc}---or put these declarations in configuration files -specific to those systems. - -@item -The string functions require special treatment. Some Unix systems have -a header file @file{string.h}; others have @file{strings.h}. Neither -file name is portable. There are two things you can do: use Autoconf to -figure out which file to include, or don't include either file. - -@item -If you don't include either strings file, you can't get declarations for -the string functions from the header file in the usual way. - -That causes less of a problem than you might think. The newer @sc{ansi} -string functions should be avoided anyway because many systems still -don't support them. The string functions you can use are these: - -@example -strcpy strncpy strcat strncat -strlen strcmp strncmp -strchr strrchr -@end example - -The copy and concatenate functions work fine without a declaration as -long as you don't use their values. Using their values without a -declaration fails on systems where the width of a pointer differs from -the width of @code{int}, and perhaps in other cases. It is trivial to -avoid using their values, so do that. - -The compare functions and @code{strlen} work fine without a declaration -on most systems, possibly all the ones that GNU software runs on. -You may find it necessary to declare them @strong{conditionally} on a -few systems. - -The search functions must be declared to return @code{char *}. Luckily, -there is no variation in the data type they return. But there is -variation in their names. Some systems give these functions the names -@code{index} and @code{rindex}; other systems use the names -@code{strchr} and @code{strrchr}. Some systems support both pairs of -names, but neither pair works on all systems. - -You should pick a single pair of names and use it throughout your -program. (Nowadays, it is better to choose @code{strchr} and -@code{strrchr} for new programs, since those are the standard @sc{ansi} -names.) Declare both of those names as functions returning @code{char -*}. On systems which don't support those names, define them as macros -in terms of the other pair. For example, here is what to put at the -beginning of your file (or in a header) if you want to use the names -@code{strchr} and @code{strrchr} throughout: - -@example -#ifndef HAVE_STRCHR -#define strchr index -#endif -#ifndef HAVE_STRRCHR -#define strrchr rindex -#endif - -char *strchr (); -char *strrchr (); -@end example -@end itemize - -Here we assume that @code{HAVE_STRCHR} and @code{HAVE_STRRCHR} are -macros defined in systems where the corresponding functions exist. -One way to get them properly defined is to use Autoconf. - -@node Internationalization -@section Internationalization - -GNU has a library called GNU gettext that makes it easy to translate the -messages in a program into various languages. You should use this -library in every program. Use English for the messages as they appear -in the program, and let gettext provide the way to translate them into -other languages. - -Using GNU gettext involves putting a call to the @code{gettext} macro -around each string that might need translation---like this: - -@example -printf (gettext ("Processing file `%s'...")); -@end example - -@noindent -This permits GNU gettext to replace the string @code{"Processing file -`%s'..."} with a translated version. - -Once a program uses gettext, please make a point of writing calls to -@code{gettext} when you add new strings that call for translation. - -Using GNU gettext in a package involves specifying a @dfn{text domain -name} for the package. The text domain name is used to separate the -translations for this package from the translations for other packages. -Normally, the text domain name should be the same as the name of the -package---for example, @samp{fileutils} for the GNU file utilities. - -To enable gettext to work well, avoid writing code that makes -assumptions about the structure of words or sentences. When you want -the precise text of a sentence to vary depending on the data, use two or -more alternative string constants each containing a complete sentences, -rather than inserting conditionalized words or phrases into a single -sentence framework. - -Here is an example of what not to do: - -@example -printf ("%d file%s processed", nfiles, - nfiles != 1 ? "s" : ""); -@end example - -@noindent -The problem with that example is that it assumes that plurals are made -by adding `s'. If you apply gettext to the format string, like this, - -@example -printf (gettext ("%d file%s processed"), nfiles, - nfiles != 1 ? "s" : ""); -@end example - -@noindent -the message can use different words, but it will still be forced to use -`s' for the plural. Here is a better way: - -@example -printf ((nfiles != 1 ? "%d files processed" - : "%d file processed"), - nfiles); -@end example - -@noindent -This way, you can apply gettext to each of the two strings -independently: - -@example -printf ((nfiles != 1 ? gettext ("%d files processed") - : gettext ("%d file processed")), - nfiles); -@end example - -@noindent -This can be any method of forming the plural of the word for ``file'', and -also handles languages that require agreement in the word for -``processed''. - -A similar problem appears at the level of sentence structure with this -code: - -@example -printf ("# Implicit rule search has%s been done.\n", - f->tried_implicit ? "" : " not"); -@end example - -@noindent -Adding @code{gettext} calls to this code cannot give correct results for -all languages, because negation in some languages requires adding words -at more than one place in the sentence. By contrast, adding -@code{gettext} calls does the job straightfowardly if the code starts -out like this: - -@example -printf (f->tried_implicit - ? "# Implicit rule search has been done.\n", - : "# Implicit rule search has not been done.\n"); -@end example - -@node Mmap -@section Mmap - -Don't assume that @code{mmap} either works on all files or fails -for all files. It may work on some files and fail on others. - -The proper way to use @code{mmap} is to try it on the specific file for -which you want to use it---and if @code{mmap} doesn't work, fall back on -doing the job in another way using @code{read} and @code{write}. - -The reason this precaution is needed is that the GNU kernel (the HURD) -provides a user-extensible file system, in which there can be many -different kinds of ``ordinary files.'' Many of them support -@code{mmap}, but some do not. It is important to make programs handle -all these kinds of files. - -@node Documentation -@chapter Documenting Programs - -@menu -* GNU Manuals:: Writing proper manuals. -* Manual Structure Details:: Specific structure conventions. -* NEWS File:: NEWS files supplement manuals. -* Change Logs:: Recording Changes -* Man Pages:: Man pages are secondary. -* Reading other Manuals:: How far you can go in learning - from other manuals. -@end menu - -@node GNU Manuals -@section GNU Manuals - -The preferred way to document part of the GNU system is to write a -manual in the Texinfo formatting language. See the Texinfo manual, -either the hardcopy, or the on-line version available through -@code{info} or the Emacs Info subsystem (@kbd{C-h i}). - -Programmers often find it most natural to structure the documentation -following the structure of the implementation, which they know. But -this structure is not necessarily good for explaining how to use the -program; it may be irrelevant and confusing for a user. - -At every level, from the sentences in a paragraph to the grouping of -topics into separate manuals, the right way to structure documentation -is according to the concepts and questions that a user will have in mind -when reading it. Sometimes this structure of ideas matches the -structure of the implementation of the software being documented---but -often they are different. Often the most important part of learning to -write good documentation is learning to notice when you are structuring -the documentation like the implementation, and think about better -alternatives. - -For example, each program in the GNU system probably ought to be -documented in one manual; but this does not mean each program should -have its own manual. That would be following the structure of the -implementation, rather than the structure that helps the user -understand. - -Instead, each manual should cover a coherent @emph{topic}. For example, -instead of a manual for @code{diff} and a manual for @code{diff3}, we -have one manual for ``comparison of files'' which covers both of those -programs, as well as @code{cmp}. By documenting these programs -together, we can make the whole subject clearer. - -The manual which discusses a program should document all of the -program's command-line options and all of its commands. It should give -examples of their use. But don't organize the manual as a list of -features. Instead, organize it logically, by subtopics. Address the -questions that a user will ask when thinking about the job that the -program does. - -In general, a GNU manual should serve both as tutorial and reference. -It should be set up for convenient access to each topic through Info, -and for reading straight through (appendixes aside). A GNU manual -should give a good introduction to a beginner reading through from the -start, and should also provide all the details that hackers want. - -That is not as hard as it first sounds. Arrange each chapter as a -logical breakdown of its topic, but order the sections, and write their -text, so that reading the chapter straight through makes sense. Do -likewise when structuring the book into chapters, and when structuring a -section into paragraphs. The watchword is, @emph{at each point, address -the most fundamental and important issue raised by the preceding text.} - -If necessary, add extra chapters at the beginning of the manual which -are purely tutorial and cover the basics of the subject. These provide -the framework for a beginner to understand the rest of the manual. The -Bison manual provides a good example of how to do this. - -Don't use Unix man pages as a model for how to write GNU documentation; -most of them are terse, badly structured, and give inadequate -explanation of the underlying concepts. (There are, of course -exceptions.) Also Unix man pages use a particular format which is -different from what we use in GNU manuals. - -Please do not use the term ``pathname'' that is used in Unix -documentation; use ``file name'' (two words) instead.

Please use ``invalid'' for this, and reserve the term -``illegal'' for violations of law. - -@node Manual Structure Details -@section Manual Structure Details - -The title page of the manual should state the version of the programs or -packages documented in the manual. The Top node of the manual should -also contain this information. If the manual is changing more -frequently than or independent of the program, also state a version -number for the manual in both of these places. - -Each program documented in the manual should should have a node named -@samp{@var{program} Invocation} or @samp{Invoking @var{program}}. This -node (together with its subnodes, if any) should describe the program's -command line arguments and how to run it (the sort of information people -would look in a man page for). Start with an @samp{@@example} -containing a template for all the options and arguments that the program -uses. - -Alternatively, put a menu item in some menu whose item name fits one of -the above patterns.

In each new release, add items to the front of the file and -identify the version they pertain to. Don't discard old items; leave -them in the file after the newer items. This way, a user upgrading from -any previous version can see what is new. - -If the @file{NEWS} file gets very long, move some of the older items -into a file named @file{ONEWS} and put a note at the end referring the -user to that file. - -@node Change Logs -@section Change Logs - -Keep a change log to describe all the changes made to program source -files. The purpose of this is so that people investigating bugs in the -future will know about the changes that might have introduced the bug. -Often a new bug can be found by looking at what was recently changed. -More importantly, change logs can help you eliminate conceptual -inconsistencies between different parts of a program, by giving you a -history of how the conflicting concepts arose and who they came from. - -@menu -* Change Log Concepts:: -* Style of Change Logs:: -* Simple Changes:: -* Conditional Changes:: -@end menu - -@node Change Log Concepts -@subsection Change Log Concepts - -You can think of the change log as a conceptual ``undo list'' which -explains how earlier versions were different from the current version. -People can see the current version; they don't need the change log -to tell them what is in it. What they want from a change log is a -clear explanation of how the earlier version differed. - -The change log file is normally called @file{ChangeLog} and covers an -entire directory. Each directory can have its own change log, or a -directory can use the change log of its parent directory--it's up to -you. - -Another alternative is to record change log information with a version -control system such as RCS or CVS. This can be converted automatically -to a @file{ChangeLog} file. - -There's no need to describe the full purpose of the changes or how they -work together. If you think that a change calls for explanation, you're -probably right. Please do explain it---but please put the explanation -in comments in the code, where people will see it whenever they see the -code. For example, ``New function'' is enough for the change log when -you add a function, because there should be a comment before the -function definition to explain what it does. - -However, sometimes it is useful to write one line to describe the -overall purpose of a batch of changes. - -The easiest way to add an entry to @file{ChangeLog} is with the Emacs -command @kbd{M-x add-change-log-entry}. An entry should have an -asterisk, the name of the changed file, and then in parentheses the name -of the changed functions, variables or whatever, followed by a colon. -Then describe the changes you made to that function or variable. - -@node Style of Change Logs -@subsection Style of Change Logs - -Here are some examples of change log entries: - -@example -* register.el (insert-register): Return nil. -(jump-to-register): Likewise. - -* sort.el (sort-subr): Return nil. - -* tex-mode.el (tex-bibtex-file, tex-file, tex-region): -Restart the tex shell if process is gone or stopped. -(tex-shell-running): New function. - -* expr.c (store_one_arg): Round size up for move_block_to_reg. -(expand_call): Round up when emitting USE insns. -* stmt.c (assign_parms): Round size up for move_block_from_reg. -@end example - -It's important to name the changed function or variable in full. Don't -abbreviate function or variable names, and don't combine them. -Subsequent maintainers will often search for a function name to find all -the change log entries that pertain to it; if you abbreviate the name, -they won't find it when they search. - -For example, some people are tempted to abbreviate groups of function -names by writing @samp{* register.el (@{insert,jump-to@}-register)}; -this is not a good idea, since searching for @code{jump-to-register} or -@code{insert-register} would not find that entry. - -Separate unrelated change log entries with blank lines. When two -entries represent parts of the same change, so that they work together, -then don't put blank lines between them. Then you can omit the file -name and the asterisk when successive entries are in the same file. - -@node Simple Changes -@subsection Simple Changes - -Certain simple kinds of changes don't need much detail in the change -log. - -When you change the calling sequence of a function in a simple fashion, -and you change all the callers of the function, there is no need to make -individual entries for all the callers that you changed. Just write in -the entry for the function being called, ``All callers changed.'' - -@example -* keyboard.c (Fcommand_execute): New arg SPECIAL. -All callers changed. -@end example - -When you change just comments or doc strings, it is enough to write an -entry for the file, without mentioning the functions. Just ``Doc -fixes'' is enough for the change log. - -There's no need to make change log entries for documentation files. -This is because documentation is not susceptible to bugs that are hard -to fix. Documentation does not consist of parts that must interact in a -precisely engineered fashion. To correct an error, you need not know -the history of the erroneous passage; it is enough to compare what the -documentation says with the way the program actually works. - -@node Conditional Changes -@subsection Conditional Changes - -C programs often contain compile-time @code{#if} conditionals. Many -changes are conditional; sometimes you add a new definition which is -entirely contained in a conditional. It is very useful to indicate in -the change log the conditions for which the change applies. - -Our convention for indicating conditional changes is to use square -brackets around the name of the condition. - -Here is a simple example, describing a change which is conditional but -does not have a function or entity name associated with it: - -@example -* xterm.c [SOLARIS2]: Include string.h. -@end example - -Here is an entry describing a new definition which is entirely -conditional. This new definition for the macro @code{FRAME_WINDOW_P} is -used only when @code{HAVE_X_WINDOWS} is defined: - -@example -* frame.h [HAVE_X_WINDOWS] (FRAME_WINDOW_P): Macro defined. -@end example - -Here is an entry for a change within the function @code{init_display}, -whose definition as a whole is unconditional, but the changes themselves -are contained in a @samp{#ifdef HAVE_LIBNCURSES} conditional: - -@example -* dispnew.c (init_display) [HAVE_LIBNCURSES]: If X, call tgetent. -@end example - -Here is an entry for a change that takes affect only when -a certain macro is @emph{not} defined: - -@example -(gethostname) [!HAVE_SOCKETS]: Replace with winsock version. -@end example - -@node Man Pages -@section Man Pages - -In the GNU project, man pages are secondary. It is not necessary or -expected for every GNU program to have a man page, but some of them do. -It's your choice whether to include a man page in your program. - -When you make this decision, consider that supporting a man page -requires continual effort each time the program is changed. The time -you spend on the man page is time taken away from more useful work. - -For a simple program which changes little, updating the man page may be -a small job. Then there is little reason not to include a man page, if -you have one. - -For a large program that changes a great deal, updating a man page may -be a substantial burden. If a user offers to donate a man page, you may -find this gift costly to accept. It may be better to refuse the man -page unless the same person agrees to take full responsibility for -maintaining it---so that you can wash your hands of it entirely. If -this volunteer later ceases to do the job, then don't feel obliged to -pick it up yourself; it may be better to withdraw the man page from the -distribution until someone else agrees to update it. - -When a program changes only a little, you may feel that the -discrepancies are small enough that the man page remains useful without -updating. If so, put a prominent note near the beginning of the man -page explaining that you don't maintain it and that the Texinfo manual -is more authoritative. The note should say how to access the Texinfo -documentation. - -@node Reading other Manuals -@section Reading other Manuals - -There may be non-free books or documentation files that describe the -program you are documenting. - -It is ok to use these documents for reference, just as the author of a -new algebra textbook can read other books on algebra. A large portion -of any non-fiction book consists of facts, in this case facts about how -a certain program works, and these facts are necessarily the same for -everyone who writes about the subject. But be careful not to copy your -outline structure, wording, tables or examples from preexisting non-free -documentation. Copying from free documentation may be ok; please check -with the FSF about the individual case. - -@node Managing Releases -@chapter The Release Process - -Making a release is more than just bundling up your source files in a -tar file and putting it up for FTP. You should set up your software so -that it can be configured to run on a variety of systems. Your Makefile -should conform to the GNU standards described below, and your directory -layout should also conform to the standards discussed below. Doing so -makes it easy to include your package into the larger framework of -all GNU software. - -@menu -* Configuration:: How Configuration Should Work -* Makefile Conventions:: Makefile Conventions -* Releases:: Making Releases -@end menu - -@node Configuration -@section How Configuration Should Work - -Each GNU distribution should come with a shell script named -@code{configure}. This script is given arguments which describe the -kind of machine and system you want to compile the program for. - -The @code{configure} script must record the configuration options so -that they affect compilation. - -One way to do this is to make a link from a standard name such as -@file{config.h} to the proper configuration file for the chosen system. -If you use this technique, the distribution should @emph{not} contain a -file named @file{config.h}. This is so that people won't be able to -build the program without configuring it first. - -Another thing that @code{configure} can do is to edit the Makefile. If -you do this, the distribution should @emph{not} contain a file named -@file{Makefile}. Instead, it should include a file @file{Makefile.in} which -contains the input used for editing. Once again, this is so that people -won't be able to build the program without configuring it first. - -If @code{configure} does write the @file{Makefile}, then @file{Makefile} -should have a target named @file{Makefile} which causes @code{configure} -to be rerun, setting up the same configuration that was set up last -time. The files that @code{configure} reads should be listed as -dependencies of @file{Makefile}. - -All the files which are output from the @code{configure} script should -have comments at the beginning explaining that they were generated -automatically using @code{configure}. This is so that users won't think -of trying to edit them by hand. - -The @code{configure} script should write a file named @file{config.status} -which describes which configuration options were specified when the -program was last configured. This file should be a shell script which, -if run, will recreate the same configuration. - -The @code{configure} script should accept an option of the form -@samp{--srcdir=@var{dirname}} to specify the directory where sources are found -(if it is not the current directory). This makes it possible to build -the program in a separate directory, so that the actual source directory -is not modified. - -If the user does not specify @samp{--srcdir}, then @code{configure} should -check both @file{.} and @file{..} to see if it can find the sources. If -it finds the sources in one of these places, it should use them from -there. Otherwise, it should report that it cannot find the sources, and -should exit with nonzero status. - -Usually the easy way to support @samp{--srcdir} is by editing a -definition of @code{VPATH} into the Makefile. Some rules may need to -refer explicitly to the specified source directory. To make this -possible, @code{configure} can add to the Makefile a variable named -@code{srcdir} whose value is precisely the specified directory. - -The @code{configure} script should also take an argument which specifies the -type of system to build the program for. This argument should look like -this: - -@example -@var{cpu}-@var{company}-@var{system} -@end example - -For example, a Sun 3 might be @samp{m68k-sun-sunos4.1}. - -The @code{configure} script needs to be able to decode all plausible -alternatives for how to describe a machine. Thus, @samp{sun3-sunos4.1} -would be a valid alias. For many programs, @samp{vax-dec-ultrix} would -be an alias for @samp{vax-dec-bsd}, simply because the differences -between Ultrix and @sc{BSD} are rarely noticeable, but a few programs -might need to distinguish them. -@c Real 4.4BSD now runs on some Suns. - -There is a shell script called @file{config.sub} that you can use -as a subroutine to validate system types and canonicalize aliases. - -Other options are permitted to specify in more detail the software -or hardware present on the machine, and include or exclude optional -parts of the package: - -@table @samp -@item --enable-@var{feature}@r{[}=@var{parameter}@r{]} -Configure the package to build and install an optional user-level -facility called @var{feature}. This allows users to choose which -optional features to include. Giving an optional @var{parameter} of -@samp{no} should omit @var{feature}, if it is built by default. - -No @samp{--enable} option should @strong{ever} cause one feature to -replace another. No @samp{--enable} option should ever substitute one -useful behavior for another useful behavior. The only proper use for -@samp{--enable} is for questions of whether to build part of the program -or exclude it. - -@item --with-@var{package} -@c @r{[}=@var{parameter}@r{]} -The package @var{package} will be installed, so configure this package -to work with @var{package}. - -@c Giving an optional @var{parameter} of -@c @samp{no} should omit @var{package}, if it is used by default. - -Possible values of @var{package} include -@samp{gnu-as} (or @samp{gas}), @samp{gnu-ld}, @samp{gnu-libc}, -@samp{gdb}, -@samp{x}, -and -@samp{x-toolkit}. - -Do not use a @samp{--with} option to specify the file name to use to -find certain files. That is outside the scope of what @samp{--with} -options are for. - -@item --nfp -The target machine has no floating point processor. - -@item --gas -The target machine assembler is GAS, the GNU assembler. -This is obsolete; users should use @samp{--with-gnu-as} instead. - -@item --x -The target machine has the X Window System installed. -This is obsolete; users should use @samp{--with-x} instead. -@end table - -All @code{configure} scripts should accept all of these ``detail'' -options, whether or not they make any difference to the particular -package at hand. In particular, they should accept any option that -starts with @samp{--with-} or @samp{--enable-}. This is so users will -be able to configure an entire GNU source tree at once with a single set -of options. - -You will note that the categories @samp{--with-} and @samp{--enable-} -are narrow: they @strong{do not} provide a place for any sort of option -you might think of. That is deliberate. We want to limit the possible -configuration options in GNU software. We do not want GNU programs to -have idiosyncratic configuration options. - -Packages that perform part of the compilation process may support cross-compilation. -In such a case, the host and target machines for the program may be -different. The @code{configure} script should normally treat the -specified type of system as both the host and the target, thus producing -a program which works for the same type of machine that it runs on. - -The way to build a cross-compiler, cross-assembler, or what have you, is -to specify the option @samp{--host=@var{hosttype}} when running -@code{configure}. This specifies the host system without changing the -type of target system. The syntax for @var{hosttype} is the same as -described above. - -Bootstrapping a cross-compiler requires compiling it on a machine other -than the host it will run on. Compilation packages accept a -configuration option @samp{--build=@var{hosttype}} for specifying the -configuration on which you will compile them, in case that is different -from the host. - -Programs for which cross-operation is not meaningful need not accept the -@samp{--host} option, because configuring an entire operating system for -cross-operation is not a meaningful thing. - -Some programs have ways of configuring themselves automatically. If -your program is set up to do this, your @code{configure} script can simply -ignore most of its arguments. - -@comment The makefile standards are in a separate file that is also -@comment included by make.texinfo.

It should unpack into a -subdirectory named @file{foo-69.96}. - -Building and installing the program should never modify any of the files -contained in the distribution. This means that all the files that form -part of the program in any way must be classified into @dfn{source -files} and @dfn{non-source files}. Source files are written by humans -and never changed automatically; non-source files are produced from -source files by programs under the control of the Makefile. - -Naturally, all the source files must be in the distribution. It is okay -to include non-source files in the distribution, provided they are -up-to-date and machine-independent, so that building the distribution -normally will never modify them. We commonly include non-source files -produced by Bison, @code{lex}, @TeX{}, and @code{makeinfo}; this helps avoid -unnecessary dependencies between our distributions, so that users can -install whichever packages they want to install. - -Non-source files that might actually be modified by building and -installing the program should @strong{never} be included in the -distribution. So if you do distribute non-source files, always make -sure they are up to date when you make a new distribution. - -Make sure that the directory into which the distribution unpacks (as -well as any subdirectories) are all world-writable (octal mode 777). -This is so that old versions of @code{tar} which preserve the -ownership and permissions of the files from the tar archive will be -able to extract all the files even if the user is unprivileged. - -Make sure that all the files in the distribution are world-readable. - -Make sure that no file name in the distribution is more than 14 -characters long. Likewise, no file created by building the program -should have a name longer than 14 characters. The reason for this is -that some systems adhere to a foolish interpretation of the POSIX -standard, and refuse to open a longer name, rather than truncating as -they did in the past. - -Don't include any symbolic links in the distribution itself. If the tar -file contains symbolic links, then people cannot even unpack it on -systems that don't support symbolic links. Also, don't use multiple -names for one file in different directories, because certain file -systems cannot handle this and that prevents unpacking the -distribution. - -Try to make sure that all the file names will be unique on MS-DOS. A -name on MS-DOS consists of up to 8 characters, optionally followed by a -period and up to three characters. MS-DOS will truncate extra -characters both before and after the period. Thus, -@file{foobarhacker.c} and @file{foobarhacker.o} are not ambiguous; they -are truncated to @file{foobarha.c} and @file{foobarha.o}, which are -distinct. - -Include in your distribution a copy of the @file{texinfo.tex} you used -to test print any @file{*.texinfo} or @file{*.texi} files. - -Likewise, if your program uses small GNU software packages like regex, -getopt, obstack, or termcap, include them in the distribution file. -Leaving them out would make the distribution file a little smaller at -the expense of possible inconvenience to a user who doesn't know what -other files to get. - -@contents - -@bye -Local variables: -update-date-leading-regexp: "@c This date is automagically updated when you save this file:\n@set lastupdate " -update-date-trailing-regexp: "" -eval: (load "/gd/gnuorg/update-date.el") -eval: (add-hook 'write-file-hooks 'update-date) -End: diff --git a/contrib/binutils/gas/acconfig.h b/contrib/binutils/gas/acconfig.h deleted file mode 100644 index c9c60025c7574..0000000000000 --- a/contrib/binutils/gas/acconfig.h +++ /dev/null @@ -1,79 +0,0 @@ -/* Name of package. */ -#undef PACKAGE - -/* Version of package. */ -#undef VERSION - -/* Should gas use high-level BFD interfaces? */ -#undef BFD_ASSEMBLER - -/* Some assert/preprocessor combinations are incapable of handling - certain kinds of constructs in the argument of assert.

So for example if the address of -'here' was 0xFFFFFFFF then without the special behaviour of the hi() -pseudo-op the movhi instruction would put 0xFFFF0000 into r6, then the -movea instruction would takes its immediate operand, 0xFFFF, sign extend -it to 32 bits, 0xFFFFFFFF, and then add it into r6 giving 0xFFFEFFFF -which is wrong (the fifth nibble is E).
