You +may copy, distribute, and modify it freely as long as you preserve this +copyright notice and permission notice. + +Installing GNU CC +***************** + + Here is the procedure for installing GNU CC on a Unix system. See +*Note VMS Install::, for VMS systems. In this section we assume you +compile in the same directory that contains the source files; see *Note +Other Dir::, to find out how to compile in a separate directory on Unix +systems. + + You cannot install GNU C by itself on MSDOS; it will not compile +under any MSDOS compiler except itself. You need to get the complete +compilation package DJGPP, which includes binaries as well as sources, +and includes all the necessary compilation tools and libraries. + + 1. If you have built GNU CC previously in the same directory for a + different target machine, do `make distclean' to delete all files + that might be invalid. One of the files this deletes is + `Makefile'; if `make distclean' complains that `Makefile' does not + exist, it probably means that the directory is already suitably + clean. + + 2. On a System V release 4 system, make sure `/usr/bin' precedes + `/usr/ucb' in `PATH'. The `cc' command in `/usr/ucb' uses + libraries which have bugs. + + 3. Specify the host, build and target machine configurations. You do + this by running the file `configure'. + + The "build" machine is the system which you are using, the "host" + machine is the system where you want to run the resulting compiler + (normally the build machine), and the "target" machine is the + system for which you want the compiler to generate code. + + If you are building a compiler to produce code for the machine it + runs on (a native compiler), you normally do not need to specify + any operands to `configure'; it will try to guess the type of + machine you are on and use that as the build, host and target + machines. So you don't need to specify a configuration when + building a native compiler unless `configure' cannot figure out + what your configuration is or guesses wrong. + + In those cases, specify the build machine's "configuration name" + with the `--build' option; the host and target will default to be + the same as the build machine. (If you are building a + cross-compiler, see *Note Cross-Compiler::.) + + Here is an example: + + ./configure --build=sparc-sun-sunos4.1 + + A configuration name may be canonical or it may be more or less + abbreviated. + + A canonical configuration name has three parts, separated by + dashes. It looks like this: `CPU-COMPANY-SYSTEM'. (The three + parts may themselves contain dashes; `configure' can figure out + which dashes serve which purpose.) For example, + `m68k-sun-sunos4.1' specifies a Sun 3. + + You can also replace parts of the configuration by nicknames or + aliases. For example, `sun3' stands for `m68k-sun', so + `sun3-sunos4.1' is another way to specify a Sun 3. You can also + use simply `sun3-sunos', since the version of SunOS is assumed by + default to be version 4. `sun3-bsd' also works, since `configure' + knows that the only BSD variant on a Sun 3 is SunOS. + + You can specify a version number after any of the system types, + and some of the CPU types. In most cases, the version is + irrelevant, and will be ignored. So you might as well specify the + version if you know it. + + See *Note Configurations::, for a list of supported configuration + names and notes on many of the configurations. You should check + the notes in that section before proceeding any further with the + installation of GNU CC. + + There are four additional options you can specify independently to + describe variant hardware and software configurations. These are + `--with-gnu-as', `--with-gnu-ld', `--with-stabs' and `--nfp'. + + `--with-gnu-as' + If you will use GNU CC with the GNU assembler (GAS), you + should declare this by using the `--with-gnu-as' option when + you run `configure'. + + Using this option does not install GAS. It only modifies the + output of GNU CC to work with GAS. Building and installing + GAS is up to you. + + Conversely, if you *do not* wish to use GAS and do not specify + `--with-gnu-as' when building GNU CC, it is up to you to make + sure that GAS is not installed. GNU CC searches for a + program named `as' in various directories; if the program it + finds is GAS, then it runs GAS. If you are not sure where + GNU CC finds the assembler it is using, try specifying `-v' + when you run it. + + The systems where it makes a difference whether you use GAS + are + `hppa1.0-ANY-ANY', `hppa1.1-ANY-ANY', `i386-ANY-sysv', + `i386-ANY-isc', + `i860-ANY-bsd', `m68k-bull-sysv', `m68k-hp-hpux', + `m68k-sony-bsd', + `m68k-altos-sysv', `m68000-hp-hpux', `m68000-att-sysv', + `ANY-lynx-lynxos', and `mips-ANY'). On any other system, + `--with-gnu-as' has no effect. + + On the systems listed above (except for the HP-PA, for ISC on + the 386, and for `mips-sgi-irix5.*'), if you use GAS, you + should also use the GNU linker (and specify `--with-gnu-ld'). + + `--with-gnu-ld' + Specify the option `--with-gnu-ld' if you plan to use the GNU + linker with GNU CC. + + This option does not cause the GNU linker to be installed; it + just modifies the behavior of GNU CC to work with the GNU + linker. Specifically, it inhibits the installation of + `collect2', a program which otherwise serves as a front-end + for the system's linker on most configurations. + + `--with-stabs' + On MIPS based systems and on Alphas, you must specify whether + you want GNU CC to create the normal ECOFF debugging format, + or to use BSD-style stabs passed through the ECOFF symbol + table. The normal ECOFF debug format cannot fully handle + languages other than C. BSD stabs format can handle other + languages, but it only works with the GNU debugger GDB. + + Normally, GNU CC uses the ECOFF debugging format by default; + if you prefer BSD stabs, specify `--with-stabs' when you + configure GNU CC. + + No matter which default you choose when you configure GNU CC, + the user can use the `-gcoff' and `-gstabs+' options to + specify explicitly the debug format for a particular + compilation. + + `--with-stabs' is meaningful on the ISC system on the 386, + also, if `--with-gas' is used. It selects use of stabs + debugging information embedded in COFF output. This kind of + debugging information supports C++ well; ordinary COFF + debugging information does not. + + `--with-stabs' is also meaningful on 386 systems running + SVR4. It selects use of stabs debugging information embedded + in ELF output. The C++ compiler currently (2.6.0) does not + support the DWARF debugging information normally used on 386 + SVR4 platforms; stabs provide a workable alternative. This + requires gas and gdb, as the normal SVR4 tools can not + generate or interpret stabs. + + `--nfp' + On certain systems, you must specify whether the machine has + a floating point unit. These systems include + `m68k-sun-sunosN' and `m68k-isi-bsd'. On any other system, + `--nfp' currently has no effect, though perhaps there are + other systems where it could usefully make a difference. + + The `configure' script searches subdirectories of the source + directory for other compilers that are to be integrated into GNU + CC. The GNU compiler for C++, called G++ is in a subdirectory + named `cp'. `configure' inserts rules into `Makefile' to build + all of those compilers. + + Here we spell out what files will be set up by `configure'. + Normally you need not be concerned with these files. + + * A file named `config.h' is created that contains a `#include' + of the top-level config file for the machine you will run the + compiler on (*note The Configuration File: + (gcc.info)Config.). This file is responsible for defining + information about the host machine. It includes `tm.h'. + + The top-level config file is located in the subdirectory + `config'. Its name is always `xm-SOMETHING.h'; usually + `xm-MACHINE.h', but there are some exceptions. + + If your system does not support symbolic links, you might + want to set up `config.h' to contain a `#include' command + which refers to the appropriate file. + + * A file named `tconfig.h' is created which includes the + top-level config file for your target machine. This is used + for compiling certain programs to run on that machine. + + * A file named `tm.h' is created which includes the + machine-description macro file for your target machine. It + should be in the subdirectory `config' and its name is often + `MACHINE.h'. + + * The command file `configure' also constructs the file + `Makefile' by adding some text to the template file + `Makefile.in'. The additional text comes from files in the + `config' directory, named `t-TARGET' and `x-HOST'. If these + files do not exist, it means nothing needs to be added for a + given target or host. + + 4. The standard directory for installing GNU CC is `/usr/local/lib'. + If you want to install its files somewhere else, specify + `--prefix=DIR' when you run `configure'. Here DIR is a directory + name to use instead of `/usr/local' for all purposes with one + exception: the directory `/usr/local/include' is searched for + header files no matter where you install the compiler. To override + this name, use the `--local-prefix' option below. + + 5. Specify `--local-prefix=DIR' if you want the compiler to search + directory `DIR/include' for locally installed header files + *instead* of `/usr/local/include'. + + You should specify `--local-prefix' *only* if your site has a + different convention (not `/usr/local') for where to put + site-specific files. + + *Do not* specify `/usr' as the `--local-prefix'! The directory + you use for `--local-prefix' *must not* contain any of the + system's standard header files. If it did contain them, certain + programs would be miscompiled (including GNU Emacs, on certain + targets), because this would override and nullify the header file + corrections made by the `fixincludes' script. + + 6. Make sure the Bison parser generator is installed. (This is + unnecessary if the Bison output files `c-parse.c' and `cexp.c' are + more recent than `c-parse.y' and `cexp.y' and you do not plan to + change the `.y' files.) + + Bison versions older than Sept 8, 1988 will produce incorrect + output for `c-parse.c'. + + 7. If you have chosen a configuration for GNU CC which requires other + GNU tools (such as GAS or the GNU linker) instead of the standard + system tools, install the required tools in the build directory + under the names `as', `ld' or whatever is appropriate. This will + enable the compiler to find the proper tools for compilation of + the program `enquire'. + + Alternatively, you can do subsequent compilation using a value of + the `PATH' environment variable such that the necessary GNU tools + come before the standard system tools. + + 8. Build the compiler. Just type `make LANGUAGES=c' in the compiler + directory. + + `LANGUAGES=c' specifies that only the C compiler should be + compiled. The makefile normally builds compilers for all the + supported languages; currently, C, C++ and Objective C. However, + C is the only language that is sure to work when you build with + other non-GNU C compilers. In addition, building anything but C + at this stage is a waste of time. + + In general, you can specify the languages to build by typing the + argument `LANGUAGES="LIST"', where LIST is one or more words from + the list `c', `c++', and `objective-c'. If you have any + additional GNU compilers as subdirectories of the GNU CC source + directory, you may also specify their names in this list. + + Ignore any warnings you may see about "statement not reached" in + `insn-emit.c'; they are normal. Also, warnings about "unknown + escape sequence" are normal in `genopinit.c' and perhaps some + other files. Likewise, you should ignore warnings about "constant + is so large that it is unsigned" in `insn-emit.c' and + `insn-recog.c' and a warning about a comparison always being zero + in `enquire.o'. Any other compilation errors may represent bugs in + the port to your machine or operating system, and should be + investigated and reported. + + Some commercial compilers fail to compile GNU CC because they have + bugs or limitations. For example, the Microsoft compiler is said + to run out of macro space. Some Ultrix compilers run out of + expression space; then you need to break up the statement where + the problem happens. + + 9. If you are building a cross-compiler, stop here. *Note + Cross-Compiler::. + + 10. Move the first-stage object files and executables into a + subdirectory with this command: + + make stage1 + + The files are moved into a subdirectory named `stage1'. Once + installation is complete, you may wish to delete these files with + `rm -r stage1'. + + 11. If you have chosen a configuration for GNU CC which requires other + GNU tools (such as GAS or the GNU linker) instead of the standard + system tools, install the required tools in the `stage1' + subdirectory under the names `as', `ld' or whatever is + appropriate. This will enable the stage 1 compiler to find the + proper tools in the following stage. + + Alternatively, you can do subsequent compilation using a value of + the `PATH' environment variable such that the necessary GNU tools + come before the standard system tools. + + 12. Recompile the compiler with itself, with this command: + + make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2" + + This is called making the stage 2 compiler. + + The command shown above builds compilers for all the supported + languages. If you don't want them all, you can specify the + languages to build by typing the argument `LANGUAGES="LIST"'. LIST + should contain one or more words from the list `c', `c++', + `objective-c', and `proto'. Separate the words with spaces. + `proto' stands for the programs `protoize' and `unprotoize'; they + are not a separate language, but you use `LANGUAGES' to enable or + disable their installation. + + If you are going to build the stage 3 compiler, then you might + want to build only the C language in stage 2. + + Once you have built the stage 2 compiler, if you are short of disk + space, you can delete the subdirectory `stage1'. + + On a 68000 or 68020 system lacking floating point hardware, unless + you have selected a `tm.h' file that expects by default that there + is no such hardware, do this instead: + + make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2 -msoft-float" + + 13. If you wish to test the compiler by compiling it with itself one + more time, install any other necessary GNU tools (such as GAS or + the GNU linker) in the `stage2' subdirectory as you did in the + `stage1' subdirectory, then do this: + + make stage2 + make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2" + + This is called making the stage 3 compiler. Aside from the `-B' + option, the compiler options should be the same as when you made + the stage 2 compiler. But the `LANGUAGES' option need not be the + same. The command shown above builds compilers for all the + supported languages; if you don't want them all, you can specify + the languages to build by typing the argument `LANGUAGES="LIST"', + as described above. + + If you do not have to install any additional GNU tools, you may + use the command + + make bootstrap LANGUAGES=LANGUAGE-LIST BOOT_CFLAGS=OPTION-LIST + + instead of making `stage1', `stage2', and performing the two + compiler builds. + + 14. Then compare the latest object files with the stage 2 object + files--they ought to be identical, aside from time stamps (if any). + + On some systems, meaningful comparison of object files is + impossible; they always appear "different." This is currently + true on Solaris and some systems that use ELF object file format. + On some versions of Irix on SGI machines and DEC Unix (OSF/1) on + Alpha systems, you will not be able to compare the files without + specifying `-save-temps'; see the description of individual + systems above to see if you get comparison failures. You may have + similar problems on other systems. + + Use this command to compare the files: + + make compare + + This will mention any object files that differ between stage 2 and + stage 3. Any difference, no matter how innocuous, indicates that + the stage 2 compiler has compiled GNU CC incorrectly, and is + therefore a potentially serious bug which you should investigate + and report. + + If your system does not put time stamps in the object files, then + this is a faster way to compare them (using the Bourne shell): + + for file in *.o; do + cmp $file stage2/$file + done + + If you have built the compiler with the `-mno-mips-tfile' option on + MIPS machines, you will not be able to compare the files. + + 15. Install the compiler driver, the compiler's passes and run-time + support with `make install'. Use the same value for `CC', + `CFLAGS' and `LANGUAGES' that you used when compiling the files + that are being installed. One reason this is necessary is that + some versions of Make have bugs and recompile files gratuitously + when you do this step. If you use the same variable values, those + files will be recompiled properly. + + For example, if you have built the stage 2 compiler, you can use + the following command: + + make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES="LIST" + + This copies the files `cc1', `cpp' and `libgcc.a' to files `cc1', + `cpp' and `libgcc.a' in the directory + `/usr/local/lib/gcc-lib/TARGET/VERSION', which is where the + compiler driver program looks for them. Here TARGET is the target + machine type specified when you ran `configure', and VERSION is + the version number of GNU CC. This naming scheme permits various + versions and/or cross-compilers to coexist. + + This also copies the driver program `xgcc' into + `/usr/local/bin/gcc', so that it appears in typical execution + search paths. + + On some systems, this command causes recompilation of some files. + This is usually due to bugs in `make'. You should either ignore + this problem, or use GNU Make. + + *Warning: there is a bug in `alloca' in the Sun library. To avoid + this bug, be sure to install the executables of GNU CC that were + compiled by GNU CC. (That is, the executables from stage 2 or 3, + not stage 1.) They use `alloca' as a built-in function and never + the one in the library.* + + (It is usually better to install GNU CC executables from stage 2 + or 3, since they usually run faster than the ones compiled with + some other compiler.) + + 16. If you're going to use C++, it's likely that you need to also + install the libg++ distribution. It should be available from the + same place where you got the GNU C distribution. Just as GNU C + does not distribute a C runtime library, it also does not include + a C++ run-time library. All I/O functionality, special class + libraries, etc., are available in the libg++ distribution. + +Configurations Supported by GNU CC +================================== + + Here are the possible CPU types: + + 1750a, a29k, alpha, arm, cN, clipper, dsp16xx, elxsi, h8300, + hppa1.0, hppa1.1, i370, i386, i486, i586, i860, i960, m68000, m68k, + m88k, mips, mipsel, mips64, mips64el, ns32k, powerpc, powerpcle, + pyramid, romp, rs6000, sh, sparc, sparclite, sparc64, vax, we32k. + + Here are the recognized company names. As you can see, customary +abbreviations are used rather than the longer official names. + + acorn, alliant, altos, apollo, att, bull, cbm, convergent, convex, + crds, dec, dg, dolphin, elxsi, encore, harris, hitachi, hp, ibm, + intergraph, isi, mips, motorola, ncr, next, ns, omron, plexus, + sequent, sgi, sony, sun, tti, unicom, wrs. + + The company name is meaningful only to disambiguate when the rest of +the information supplied is insufficient. You can omit it, writing +just `CPU-SYSTEM', if it is not needed. For example, `vax-ultrix4.2' +is equivalent to `vax-dec-ultrix4.2'. + + Here is a list of system types: + + 386bsd, aix, acis, amigados, aos, aout, bosx, bsd, clix, coff, + ctix, cxux, dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms, + genix, gnu, gnu/linux, hiux, hpux, iris, irix, isc, luna, lynxos, + mach, minix, msdos, mvs, netbsd, newsos, nindy, ns, osf, osfrose, + ptx, riscix, riscos, rtu, sco, sim, solaris, sunos, sym, sysv, + udi, ultrix, unicos, uniplus, unos, vms, vsta, vxworks, winnt, + xenix. + +You can omit the system type; then `configure' guesses the operating +system from the CPU and company. + + You can add a version number to the system type; this may or may not +make a difference. For example, you can write `bsd4.3' or `bsd4.4' to +distinguish versions of BSD. In practice, the version number is most +needed for `sysv3' and `sysv4', which are often treated differently. + + If you specify an impossible combination such as `i860-dg-vms', then +you may get an error message from `configure', or it may ignore part of +the information and do the best it can with the rest. `configure' +always prints the canonical name for the alternative that it used. GNU +CC does not support all possible alternatives. + + Often a particular model of machine has a name. Many machine names +are recognized as aliases for CPU/company combinations. Thus, the +machine name `sun3', mentioned above, is an alias for `m68k-sun'. +Sometimes we accept a company name as a machine name, when the name is +popularly used for a particular machine. Here is a table of the known +machine names: + + 3300, 3b1, 3bN, 7300, altos3068, altos, apollo68, att-7300, + balance, convex-cN, crds, decstation-3100, decstation, delta, + encore, fx2800, gmicro, hp7NN, hp8NN, hp9k2NN, hp9k3NN, hp9k7NN, + hp9k8NN, iris4d, iris, isi68, m3230, magnum, merlin, miniframe, + mmax, news-3600, news800, news, next, pbd, pc532, pmax, powerpc, + powerpcle, ps2, risc-news, rtpc, sun2, sun386i, sun386, sun3, + sun4, symmetry, tower-32, tower. + +Remember that a machine name specifies both the cpu type and the company +name. If you want to install your own homemade configuration files, +you can use `local' as the company name to access them. If you use +configuration `CPU-local', the configuration name without the cpu prefix +is used to form the configuration file names. + + Thus, if you specify `m68k-local', configuration uses files +`m68k.md', `local.h', `m68k.c', `xm-local.h', `t-local', and `x-local', +all in the directory `config/m68k'. + + Here is a list of configurations that have special treatment or +special things you must know: + +`1750a-*-*' + MIL-STD-1750A processors. + + Starting with GCC 2.6.1, the MIL-STD-1750A cross configuration no + longer supports the Tektronix Assembler, but instead produces + output for `as1750', an assembler/linker available under the GNU + Public License for the 1750A. Contact *kellogg@space.otn.dasa.de* + for more details on obtaining `as1750'. A similarly licensed + simulator for the 1750A is available from same address. + + You should ignore a fatal error during the building of libgcc + (libgcc is not yet implemented for the 1750A.) + + The `as1750' assembler requires the file `ms1750.inc', which is + found in the directory `config/1750a'. + + GNU CC produced the same sections as the Fairchild F9450 C + Compiler, namely: + + `Normal' + The program code section. + + `Static' + The read/write (RAM) data section. + + `Konst' + The read-only (ROM) constants section. + + `Init' + Initialization section (code to copy KREL to SREL). + + The smallest addressable unit is 16 bits (BITS_PER_UNIT is 16). + This means that type `char' is represented with a 16-bit word per + character. The 1750A's "Load/Store Upper/Lower Byte" instructions + are not used by GNU CC. + +`alpha-*-osf1' + Systems using processors that implement the DEC Alpha architecture + and are running the DEC Unix (OSF/1) operating system, for example + the DEC Alpha AXP systems. (VMS on the Alpha is not currently + supported by GNU CC.) + + GNU CC writes a `.verstamp' directive to the assembler output file + unless it is built as a cross-compiler. It gets the version to + use from the system header file `/usr/include/stamp.h'. If you + install a new version of DEC Unix, you should rebuild GCC to pick + up the new version stamp. + + Note that since the Alpha is a 64-bit architecture, + cross-compilers from 32-bit machines will not generate code as + efficient as that generated when the compiler is running on a + 64-bit machine because many optimizations that depend on being + able to represent a word on the target in an integral value on the + host cannot be performed. Building cross-compilers on the Alpha + for 32-bit machines has only been tested in a few cases and may + not work properly. + + `make compare' may fail on old versions of DEC Unix unless you add + `-save-temps' to `CFLAGS'. On these systems, the name of the + assembler input file is stored in the object file, and that makes + comparison fail if it differs between the `stage1' and `stage2' + compilations. The option `-save-temps' forces a fixed name to be + used for the assembler input file, instead of a randomly chosen + name in `/tmp'. Do not add `-save-temps' unless the comparisons + fail without that option. If you add `-save-temps', you will have + to manually delete the `.i' and `.s' files after each series of + compilations. + + GNU CC now supports both the native (ECOFF) debugging format used + by DBX and GDB and an encapsulated STABS format for use only with + GDB. See the discussion of the `--with-stabs' option of + `configure' above for more information on these formats and how to + select them. + + There is a bug in DEC's assembler that produces incorrect line + numbers for ECOFF format when the `.align' directive is used. To + work around this problem, GNU CC will not emit such alignment + directives while writing ECOFF format debugging information even + if optimization is being performed. Unfortunately, this has the + very undesirable side-effect that code addresses when `-O' is + specified are different depending on whether or not `-g' is also + specified. + + To avoid this behavior, specify `-gstabs+' and use GDB instead of + DBX. DEC is now aware of this problem with the assembler and + hopes to provide a fix shortly. + +`arm' + Advanced RISC Machines ARM-family processors. These are often + used in embedded applications.

Normally, + you would not select this configuration. + + The MIPS C compiler needs to be told to increase its table size + for switch statements with the `-Wf,-XNg1500' option in order to + compile `cp/parse.c'. If you use the `-O2' optimization option, + you also need to use `-Olimit 3000'. Both of these options are + automatically generated in the `Makefile' that the shell script + `configure' builds.

The easiest way to handle this problem is + to *not* specify a target when configuring GNU CC, the `configure' + script will try to automatically determine the right processor + type and operating system. + + `-g' does not work on HP-UX, since that system uses a peculiar + debugging format which GNU CC does not know about. However, `-g' + will work if you also use GAS and GDB in conjunction with GCC.

GNU CC version 2 compiled with GNU CC (any + version) seems not to have this problem. + + See *Note Sun Install::, for information on installing GNU CC on + Sun systems. + +`i[345]86-*-winnt3.5' + This version requires a GAS that has not let been released. Until + it is, you can get a prebuilt binary version via anonymous ftp from + `cs.washington.edu:pub/gnat' or `cs.nyu.edu:pub/gnat'. You must + also use the Microsoft header files from the Windows NT 3.5 SDK. + Find these on the CDROM in the `/mstools/h' directory dated + 9/4/94. You must use a fixed version of Microsoft linker made + especially for NT 3.5, which is also is available on the NT 3.5 + SDK CDROM. If you do not have this linker, can you also use the + linker from Visual C/C++ 1.0 or 2.0. + + Installing GNU CC for NT builds a wrapper linker, called `ld.exe', + which mimics the behaviour of Unix `ld' in the specification of + libraries (`-L' and `-l'). `ld.exe' looks for both Unix and + Microsoft named libraries. For example, if you specify `-lfoo', + `ld.exe' will look first for `libfoo.a' and then for `foo.lib'. + + You may install GNU CC for Windows NT in one of two ways, + depending on whether or not you have a Unix-like shell and various + Unix-like utilities. + + 1. If you do not have a Unix-like shell and few Unix-like + utilities, you will use a DOS style batch script called + `configure.bat'. Invoke it as `configure winnt' from an + MSDOS console window or from the program manager dialog box. + `configure.bat' assumes you have already installed and have + in your path a Unix-like `sed' program which is used to + create a working `Makefile' from `Makefile.in'. + + `Makefile' uses the Microsoft Nmake program maintenance + utility and the Visual C/C++ V8.00 compiler to build GNU CC. + You need only have the utilities `sed' and `touch' to use + this installation method, which only automatically builds the + compiler itself. You must then examine what `fixinc.winnt' + does, edit the header files by hand and build `libgcc.a' + manually. + + 2. The second type of installation assumes you are running a + Unix-like shell, have a complete suite of Unix-like utilities + in your path, and have a previous version of GNU CC already + installed, either through building it via the above + installation method or acquiring a pre-built binary. In this + case, use the `configure' script in the normal fashion. + +`i860-intel-osf1' + This is the Paragon. If you have version 1.0 of the operating + system, you need to take special steps to build GNU CC due to + peculiarities of the system. Newer system versions have no + problem. See the section `Installation Problems' in the GNU CC + Manual. + +`*-lynx-lynxos' + LynxOS 2.2 and earlier comes with GNU CC 1.x already installed as + `/bin/gcc'. You should compile with this instead of `/bin/cc'. + You can tell GNU CC to use the GNU assembler and linker, by + specifying `--with-gnu-as --with-gnu-ld' when configuring. These + will produce COFF format object files and executables; otherwise + GNU CC will use the installed tools, which produce a.out format + executables. + +`m68000-hp-bsd' + HP 9000 series 200 running BSD.

Details in the file + `README.ALTOS'. + +`m68k-att-sysv' + AT&T 3b1, a.k.a. 7300 PC. Special procedures are needed to + compile GNU CC with this machine's standard C compiler, due to + bugs in that compiler. You can bootstrap it more easily with + previous versions of GNU CC if you have them. + + Installing GNU CC on the 3b1 is difficult if you do not already + have GNU CC running, due to bugs in the installed C compiler. + However, the following procedure might work. We are unable to + test it. + + 1. Comment out the `#include "config.h"' line on line 37 of + `cccp.c' and do `make cpp'. This makes a preliminary version + of GNU cpp. + + 2. Save the old `/lib/cpp' and copy the preliminary GNU cpp to + that file name. + + 3. Undo your change in `cccp.c', or reinstall the original + version, and do `make cpp' again. + + 4. Copy this final version of GNU cpp into `/lib/cpp'. + + 5. Replace every occurrence of `obstack_free' in the file + `tree.c' with `_obstack_free'. + + 6. Run `make' to get the first-stage GNU CC. + + 7. Reinstall the original version of `/lib/cpp'. + + 8. Now you can compile GNU CC with itself and install it in the + normal fashion. + +`m68k-bull-sysv' + Bull DPX/2 series 200 and 300 with BOS-2.00.45 up to BOS-2.01. GNU + CC works either with native assembler or GNU assembler.

For some + strange reason linking `/bin/as' to `/bin/casm' changes the + behavior, and does not work. So, when installing GNU CC, you + should install the following script as `as' in the subdirectory + where the passes of GCC are installed: + + #!/bin/sh + casm $* + + The default Unos library is named `libunos.a' instead of `libc.a'. + To allow GNU CC to function, either change all references to + `-lc' in `gcc.c' to `-lunos' or link `/lib/libc.a' to + `/lib/libunos.a'. + + When compiling GNU CC with the standard compiler, to overcome bugs + in the support of `alloca', do not use `-O' when making stage 2. + Then use the stage 2 compiler with `-O' to make the stage 3 + compiler. This compiler will have the same characteristics as the + usual stage 2 compiler on other systems. Use it to make a stage 4 + compiler and compare that with stage 3 to verify proper + compilation. + + (Perhaps simply defining `ALLOCA' in `x-crds' as described in the + comments there will make the above paragraph superfluous. Please + inform us of whether this works.) + + Unos uses memory segmentation instead of demand paging, so you + will need a lot of memory. 5 Mb is barely enough if no other + tasks are running. If linking `cc1' fails, try putting the object + files into a library and linking from that library. + +`m68k-hp-hpux' + HP 9000 series 300 or 400 running HP-UX. HP-UX version 8.0 has a + bug in the assembler that prevents compilation of GNU CC.

Earlier versions of gas relied upon a program which + converted the gas output into the native HP/UX format, but that + program has not been kept up to date. gdb does not understand + that native HP/UX format, so you must use gas if you wish to use + gdb. + +`m68k-sun' + Sun 3.

There are apparently bugs in this compiler + that result in object files differences between stage 2 and stage + 3. If this happens, make the stage 4 compiler and compare it to + the stage 3 compiler. If the stage 3 and stage 4 object files are + identical, this suggests you encountered a problem with the + standard C compiler; the stage 3 and 4 compilers may be usable. + + It is best, however, to use an older version of GNU CC for + bootstrapping if you have one. + +`m88k-*-dgux' + Motorola m88k running DG/UX.

GNU CC does not support AIX running on the RT. We + recommend you compile GNU CC with an earlier version of itself; if + you compile GNU CC with `hc', the Metaware compiler, it will work, + but you will get mismatches between the stage 2 and stage 3 + compilers in various files. These errors are minor differences in + some floating-point constants and can be safely ignored; the stage + 3 compiler is correct. + +`rs6000-*-aix' +`powerpc-*-aix' + Various early versions of each release of the IBM XLC compiler + will not bootstrap GNU CC.

Known problematic releases include: + xlc-1.2.1.8, xlc-1.3.0.0 (distributed with AIX 3.2.5), and + xlc-1.3.0.19. Both xlc-1.2.1.28 and xlc-1.3.0.24 (PTF 432238) are + known to produce working versions of GNU CC, but most other recent + releases correctly bootstrap GNU CC.

Also, if you are using AIX 3.2.5 or greater and the GNU + assembler, you must have a version modified after October 16th, + 1995 in order for the GNU C compiler to build.

There have been problems reported where the library + linked with GNU CC does not produce the same floating-point + formats that the assembler accepts. If you have this problem, set + the LANG environment variable to "C" or "En_US". + + Due to changes in the way that GNU CC invokes the binder (linker) + for AIX 4.1, you may now receive warnings of duplicate symbols + from the link step that were not reported before.

Make sure you have a version of Make that supports the `VPATH' + feature. (GNU Make supports it, as do Make versions on most BSD + systems.) + + 2. If you have ever run `configure' in the source directory, you must + undo the configuration. Do this by running: + + make distclean + + 3. Go to the directory in which you want to build the compiler before + running `configure': + + mkdir gcc-sun3 + cd gcc-sun3 + + On systems that do not support symbolic links, this directory must + be on the same file system as the source code directory. + + 4. Specify where to find `configure' when you run it: + + ../gcc/configure ... + + This also tells `configure' where to find the compiler sources; + `configure' takes the directory from the file name that was used to + invoke it. But if you want to be sure, you can specify the source + directory with the `--srcdir' option, like this: + + ../gcc/configure --srcdir=../gcc OTHER OPTIONS + + The directory you specify with `--srcdir' need not be the same as + the one that `configure' is found in. + + Now, you can run `make' in that directory. You need not repeat the +configuration steps shown above, when ordinary source files change. You +must, however, run `configure' again when the configuration files +change, if your system does not support symbolic links. + +Building and Installing a Cross-Compiler +======================================== + + GNU CC can function as a cross-compiler for many machines, but not +all. + + * Cross-compilers for the Mips as target using the Mips assembler + currently do not work, because the auxiliary programs + `mips-tdump.c' and `mips-tfile.c' can't be compiled on anything + but a Mips. It does work to cross compile for a Mips if you use + the GNU assembler and linker. + + * Cross-compilers between machines with different floating point + formats have not all been made to work. GNU CC now has a floating + point emulator with which these can work, but each target machine + description needs to be updated to take advantage of it. + + * Cross-compilation between machines of different word sizes is + somewhat problematic and sometimes does not work. + + Since GNU CC generates assembler code, you probably need a +cross-assembler that GNU CC can run, in order to produce object files. +If you want to link on other than the target machine, you need a +cross-linker as well. You also need header files and libraries suitable +for the target machine that you can install on the host machine. + +Steps of Cross-Compilation +-------------------------- + + To compile and run a program using a cross-compiler involves several +steps: + + * Run the cross-compiler on the host machine to produce assembler + files for the target machine. This requires header files for the + target machine. + + * Assemble the files produced by the cross-compiler. You can do this + either with an assembler on the target machine, or with a + cross-assembler on the host machine. + + * Link those files to make an executable. You can do this either + with a linker on the target machine, or with a cross-linker on the + host machine. Whichever machine you use, you need libraries and + certain startup files (typically `crt....o') for the target + machine. + + It is most convenient to do all of these steps on the same host +machine, since then you can do it all with a single invocation of GNU +CC. This requires a suitable cross-assembler and cross-linker. For +some targets, the GNU assembler and linker are available. + +Configuring a Cross-Compiler +---------------------------- + + To build GNU CC as a cross-compiler, you start out by running +`configure'. Use the `--target=TARGET' to specify the target type. If +`configure' was unable to correctly identify the system you are running +on, also specify the `--build=BUILD' option. For example, here is how +to configure for a cross-compiler that produces code for an HP 68030 +system running BSD on a system that `configure' can correctly identify: + + ./configure --target=m68k-hp-bsd4.3 + +Tools and Libraries for a Cross-Compiler +---------------------------------------- + + If you have a cross-assembler and cross-linker available, you should +install them now. Put them in the directory `/usr/local/TARGET/bin'. +Here is a table of the tools you should put in this directory: + +`as' + This should be the cross-assembler. + +`ld' + This should be the cross-linker. + +`ar' + This should be the cross-archiver: a program which can manipulate + archive files (linker libraries) in the target machine's format. + +`ranlib' + This should be a program to construct a symbol table in an archive + file. + + The installation of GNU CC will find these programs in that +directory, and copy or link them to the proper place to for the +cross-compiler to find them when run later. + + The easiest way to provide these files is to build the Binutils +package and GAS. Configure them with the same `--host' and `--target' +options that you use for configuring GNU CC, then build and install +them. They install their executables automatically into the proper +directory. Alas, they do not support all the targets that GNU CC +supports. + + If you want to install libraries to use with the cross-compiler, +such as a standard C library, put them in the directory +`/usr/local/TARGET/lib'; installation of GNU CC copies all all the +files in that subdirectory into the proper place for GNU CC to find +them and link with them. Here's an example of copying some libraries +from a target machine: + + ftp TARGET-MACHINE + lcd /usr/local/TARGET/lib + cd /lib + get libc.a + cd /usr/lib + get libg.a + get libm.a + quit + +The precise set of libraries you'll need, and their locations on the +target machine, vary depending on its operating system. + + Many targets require "start files" such as `crt0.o' and `crtn.o' +which are linked into each executable; these too should be placed in +`/usr/local/TARGET/lib'. There may be several alternatives for +`crt0.o', for use with profiling or other compilation options. Check +your target's definition of `STARTFILE_SPEC' to find out what start +files it uses. Here's an example of copying these files from a target +machine: + + ftp TARGET-MACHINE + lcd /usr/local/TARGET/lib + prompt + cd /lib + mget *crt*.o + cd /usr/lib + mget *crt*.o + quit + +`libgcc.a' and Cross-Compilers +------------------------------ + + Code compiled by GNU CC uses certain runtime support functions +implicitly. Some of these functions can be compiled successfully with +GNU CC itself, but a few cannot be. These problem functions are in the +source file `libgcc1.c'; the library made from them is called +`libgcc1.a'. + + When you build a native compiler, these functions are compiled with +some other compiler-the one that you use for bootstrapping GNU CC. +Presumably it knows how to open code these operations, or else knows how +to call the run-time emulation facilities that the machine comes with. +But this approach doesn't work for building a cross-compiler. The +compiler that you use for building knows about the host system, not the +target system. + + So, when you build a cross-compiler you have to supply a suitable +library `libgcc1.a' that does the job it is expected to do. + + To compile `libgcc1.c' with the cross-compiler itself does not work. +The functions in this file are supposed to implement arithmetic +operations that GNU CC does not know how to open code for your target +machine. If these functions are compiled with GNU CC itself, they will +compile into infinite recursion. + + On any given target, most of these functions are not needed. If GNU +CC can open code an arithmetic operation, it will not call these +functions to perform the operation. It is possible that on your target +machine, none of these functions is needed. If so, you can supply an +empty library as `libgcc1.a'. + + Many targets need library support only for multiplication and +division. If you are linking with a library that contains functions for +multiplication and division, you can tell GNU CC to call them directly +by defining the macros `MULSI3_LIBCALL', and the like. These macros +need to be defined in the target description macro file. For some +targets, they are defined already. This may be sufficient to avoid the +need for libgcc1.a; if so, you can supply an empty library. + + Some targets do not have floating point instructions; they need other +functions in `libgcc1.a', which do floating arithmetic. Recent +versions of GNU CC have a file which emulates floating point. With a +certain amount of work, you should be able to construct a floating +point emulator that can be used as `libgcc1.a'. Perhaps future +versions will contain code to do this automatically and conveniently. +That depends on whether someone wants to implement it. + + Some embedded targets come with all the necessary `libgcc1.a' +routines written in C or assembler. These targets build `libgcc1.a' +automatically and you do not need to do anything special for them. +Other embedded targets do not need any `libgcc1.a' routines since all +the necessary operations are supported by the hardware. + + If your target system has another C compiler, you can configure GNU +CC as a native compiler on that machine, build just `libgcc1.a' with +`make libgcc1.a' on that machine, and use the resulting file with the +cross-compiler. To do this, execute the following on the target +machine: + + cd TARGET-BUILD-DIR + ./configure --host=sparc --target=sun3 + make libgcc1.a + +And then this on the host machine: + + ftp TARGET-MACHINE + binary + cd TARGET-BUILD-DIR + get libgcc1.a + quit + + Another way to provide the functions you need in `libgcc1.a' is to +define the appropriate `perform_...' macros for those functions. If +these definitions do not use the C arithmetic operators that they are +meant to implement, you should be able to compile them with the +cross-compiler you are building. (If these definitions already exist +for your target file, then you are all set.) + + To build `libgcc1.a' using the perform macros, use +`LIBGCC1=libgcc1.a OLDCC=./xgcc' when building the compiler. +Otherwise, you should place your replacement library under the name +`libgcc1.a' in the directory in which you will build the +cross-compiler, before you run `make'. + +Cross-Compilers and Header Files +-------------------------------- + + If you are cross-compiling a standalone program or a program for an +embedded system, then you may not need any header files except the few +that are part of GNU CC (and those of your program). However, if you +intend to link your program with a standard C library such as `libc.a', +then you probably need to compile with the header files that go with +the library you use. + + The GNU C compiler does not come with these files, because (1) they +are system-specific, and (2) they belong in a C library, not in a +compiler. + + If the GNU C library supports your target machine, then you can get +the header files from there (assuming you actually use the GNU library +when you link your program). + + If your target machine comes with a C compiler, it probably comes +with suitable header files also. If you make these files accessible +from the host machine, the cross-compiler can use them also. + + Otherwise, you're on your own in finding header files to use when +cross-compiling. + + When you have found suitable header files, put them in +`/usr/local/TARGET/include', before building the cross compiler. Then +installation will run fixincludes properly and install the corrected +versions of the header files where the compiler will use them. + + Provide the header files before you build the cross-compiler, because +the build stage actually runs the cross-compiler to produce parts of +`libgcc.a'. (These are the parts that *can* be compiled with GNU CC.) +Some of them need suitable header files. + + Here's an example showing how to copy the header files from a target +machine. On the target machine, do this: + + (cd /usr/include; tar cf - .) > tarfile + + Then, on the host machine, do this: + + ftp TARGET-MACHINE + lcd /usr/local/TARGET/include + get tarfile + quit + tar xf tarfile + +Actually Building the Cross-Compiler +------------------------------------ + + Now you can proceed just as for compiling a single-machine compiler +through the step of building stage 1. If you have not provided some +sort of `libgcc1.a', then compilation will give up at the point where +it needs that file, printing a suitable error message. If you do +provide `libgcc1.a', then building the compiler will automatically +compile and link a test program called `libgcc1-test'; if you get +errors in the linking, it means that not all of the necessary routines +in `libgcc1.a' are available. + + You must provide the header file `float.h'. One way to do this is +to compile `enquire' and run it on your target machine. The job of +`enquire' is to run on the target machine and figure out by experiment +the nature of its floating point representation. `enquire' records its +findings in the header file `float.h'. If you can't produce this file +by running `enquire' on the target machine, then you will need to come +up with a suitable `float.h' in some other way (or else, avoid using it +in your programs). + + Do not try to build stage 2 for a cross-compiler. It doesn't work to +rebuild GNU CC as a cross-compiler using the cross-compiler, because +that would produce a program that runs on the target machine, not on the +host. For example, if you compile a 386-to-68030 cross-compiler with +itself, the result will not be right either for the 386 (because it was +compiled into 68030 code) or for the 68030 (because it was configured +for a 386 as the host). If you want to compile GNU CC into 68030 code, +whether you compile it on a 68030 or with a cross-compiler on a 386, you +must specify a 68030 as the host when you configure it. + + To install the cross-compiler, use `make install', as usual. + +Installing GNU CC on the Sun +============================ + + On Solaris (version 2.1), do not use the linker or other tools in +`/usr/ucb' to build GNU CC. Use `/usr/ccs/bin'. + + Make sure the environment variable `FLOAT_OPTION' is not set when +you compile `libgcc.a'. If this option were set to `f68881' when +`libgcc.a' is compiled, the resulting code would demand to be linked +with a special startup file and would not link properly without special +pains. + + There is a bug in `alloca' in certain versions of the Sun library. +To avoid this bug, install the binaries of GNU CC that were compiled by +GNU CC. They use `alloca' as a built-in function and never the one in +the library. + + Some versions of the Sun compiler crash when compiling GNU CC. The +problem is a segmentation fault in cpp. This problem seems to be due to +the bulk of data in the environment variables. You may be able to avoid +it by using the following command to compile GNU CC with Sun CC: + + make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc" + +Installing GNU CC on VMS +======================== + + The VMS version of GNU CC is distributed in a backup saveset +containing both source code and precompiled binaries. + + To install the `gcc' command so you can use the compiler easily, in +the same manner as you use the VMS C compiler, you must install the VMS +CLD file for GNU CC as follows: + + 1. Define the VMS logical names `GNU_CC' and `GNU_CC_INCLUDE' to + point to the directories where the GNU CC executables + (`gcc-cpp.exe', `gcc-cc1.exe', etc.) and the C include files are + kept respectively. This should be done with the commands: + + $ assign /system /translation=concealed - + disk:[gcc.] gnu_cc + $ assign /system /translation=concealed - + disk:[gcc.include.] gnu_cc_include + + with the appropriate disk and directory names. These commands can + be placed in your system startup file so they will be executed + whenever the machine is rebooted. You may, if you choose, do this + via the `GCC_INSTALL.COM' script in the `[GCC]' directory. + + 2. Install the `GCC' command with the command line: + + $ set command /table=sys$common:[syslib]dcltables - + /output=sys$common:[syslib]dcltables gnu_cc:[000000]gcc + $ install replace sys$common:[syslib]dcltables + + 3. To install the help file, do the following: + + $ library/help sys$library:helplib.hlb gcc.hlp + + Now you can invoke the compiler with a command like `gcc /verbose + file.c', which is equivalent to the command `gcc -v -c file.c' in + Unix. + + If you wish to use GNU C++ you must first install GNU CC, and then +perform the following steps: + + 1. Define the VMS logical name `GNU_GXX_INCLUDE' to point to the + directory where the preprocessor will search for the C++ header + files. This can be done with the command: + + $ assign /system /translation=concealed - + disk:[gcc.gxx_include.] gnu_gxx_include + + with the appropriate disk and directory name. If you are going to + be using libg++, this is where the libg++ install procedure will + install the libg++ header files. + + 2. Obtain the file `gcc-cc1plus.exe', and place this in the same + directory that `gcc-cc1.exe' is kept. + + The GNU C++ compiler can be invoked with a command like `gcc /plus + /verbose file.cc', which is equivalent to the command `g++ -v -c + file.cc' in Unix. + + We try to put corresponding binaries and sources on the VMS +distribution tape. But sometimes the binaries will be from an older +version than the sources, because we don't always have time to update +them. (Use the `/version' option to determine the version number of +the binaries and compare it with the source file `version.c' to tell +whether this is so.) In this case, you should use the binaries you get +to recompile the sources. If you must recompile, here is how: + + 1. Execute the command procedure `vmsconfig.com' to set up the files + `tm.h', `config.h', `aux-output.c', and `md.', and to create files + `tconfig.h' and `hconfig.h'. This procedure also creates several + linker option files used by `make-cc1.com' and a data file used by + `make-l2.com'. + + $ @vmsconfig.com + + 2. Setup the logical names and command tables as defined above. In + addition, define the VMS logical name `GNU_BISON' to point at the + to the directories where the Bison executable is kept. This + should be done with the command: + + $ assign /system /translation=concealed - + disk:[bison.] gnu_bison + + You may, if you choose, use the `INSTALL_BISON.COM' script in the + `[BISON]' directory. + + 3. Install the `BISON' command with the command line: + + $ set command /table=sys$common:[syslib]dcltables - + /output=sys$common:[syslib]dcltables - + gnu_bison:[000000]bison + $ install replace sys$common:[syslib]dcltables + + 4. Type `@make-gcc' to recompile everything (alternatively, submit + the file `make-gcc.com' to a batch queue). If you wish to build + the GNU C++ compiler as well as the GNU CC compiler, you must + first edit `make-gcc.com' and follow the instructions that appear + in the comments. + + 5. In order to use GCC, you need a library of functions which GCC + compiled code will call to perform certain tasks, and these + functions are defined in the file `libgcc2.c'. To compile this + you should use the command procedure `make-l2.com', which will + generate the library `libgcc2.olb'. `libgcc2.olb' should be built + using the compiler built from the same distribution that + `libgcc2.c' came from, and `make-gcc.com' will automatically do + all of this for you. + + To install the library, use the following commands: + + $ library gnu_cc:[000000]gcclib/delete=(new,eprintf) + $ library gnu_cc:[000000]gcclib/delete=L_* + $ library libgcc2/extract=*/output=libgcc2.obj + $ library gnu_cc:[000000]gcclib libgcc2.obj + + The first command simply removes old modules that will be replaced + with modules from `libgcc2' under different module names. The + modules `new' and `eprintf' may not actually be present in your + `gcclib.olb'--if the VMS librarian complains about those modules + not being present, simply ignore the message and continue on with + the next command. The second command removes the modules that + came from the previous version of the library `libgcc2.c'. + + Whenever you update the compiler on your system, you should also + update the library with the above procedure. + + 6. You may wish to build GCC in such a way that no files are written + to the directory where the source files reside. An example would + be the when the source files are on a read-only disk. In these + cases, execute the following DCL commands (substituting your + actual path names): + + $ assign dua0:[gcc.build_dir.]/translation=concealed, - + dua1:[gcc.source_dir.]/translation=concealed gcc_build + $ set default gcc_build:[000000] + + where the directory `dua1:[gcc.source_dir]' contains the source + code, and the directory `dua0:[gcc.build_dir]' is meant to contain + all of the generated object files and executables. Once you have + done this, you can proceed building GCC as described above. (Keep + in mind that `gcc_build' is a rooted logical name, and thus the + device names in each element of the search list must be an actual + physical device name rather than another rooted logical name). + + 7. *If you are building GNU CC with a previous version of GNU CC, you + also should check to see that you have the newest version of the + assembler*. In particular, GNU CC version 2 treats global constant + variables slightly differently from GNU CC version 1, and GAS + version 1.38.1 does not have the patches required to work with GCC + version 2. If you use GAS 1.38.1, then `extern const' variables + will not have the read-only bit set, and the linker will generate + warning messages about mismatched psect attributes for these + variables. These warning messages are merely a nuisance, and can + safely be ignored. + + If you are compiling with a version of GNU CC older than 1.33, + specify `/DEFINE=("inline=")' as an option in all the + compilations. This requires editing all the `gcc' commands in + `make-cc1.com'. (The older versions had problems supporting + `inline'.) Once you have a working 1.33 or newer GNU CC, you can + change this file back. + + 8. If you want to build GNU CC with the VAX C compiler, you will need + to make minor changes in `make-cccp.com' and `make-cc1.com' to + choose alternate definitions of `CC', `CFLAGS', and `LIBS'. See + comments in those files. However, you must also have a working + version of the GNU assembler (GNU as, aka GAS) as it is used as + the back-end for GNU CC to produce binary object modules and is + not included in the GNU CC sources. GAS is also needed to compile + `libgcc2' in order to build `gcclib' (see above); `make-l2.com' + expects to be able to find it operational in + `gnu_cc:[000000]gnu-as.exe'. + + To use GNU CC on VMS, you need the VMS driver programs `gcc.exe', + `gcc.com', and `gcc.cld'. They are distributed with the VMS + binaries (`gcc-vms') rather than the GNU CC sources. GAS is also + included in `gcc-vms', as is Bison. + + Once you have successfully built GNU CC with VAX C, you should use + the resulting compiler to rebuild itself. Before doing this, be + sure to restore the `CC', `CFLAGS', and `LIBS' definitions in + `make-cccp.com' and `make-cc1.com'. The second generation + compiler will be able to take advantage of many optimizations that + must be suppressed when building with other compilers. + + Under previous versions of GNU CC, the generated code would +occasionally give strange results when linked with the sharable +`VAXCRTL' library. Now this should work. + + Even with this version, however, GNU CC itself should not be linked +with the sharable `VAXCRTL'. The version of `qsort' in `VAXCRTL' has a +bug (known to be present in VMS versions V4.6 through V5.5) which +causes the compiler to fail. + + The executables are generated by `make-cc1.com' and `make-cccp.com' +use the object library version of `VAXCRTL' in order to make use of the +`qsort' routine in `gcclib.olb'. If you wish to link the compiler +executables with the shareable image version of `VAXCRTL', you should +edit the file `tm.h' (created by `vmsconfig.com') to define the macro +`QSORT_WORKAROUND'. + + `QSORT_WORKAROUND' is always defined when GNU CC is compiled with +VAX C, to avoid a problem in case `gcclib.olb' is not yet available. + +`collect2' +========== + + Many target systems do not have support in the assembler and linker +for "constructors"--initialization functions to be called before the +official "start" of `main'. On such systems, GNU CC uses a utility +called `collect2' to arrange to call these functions at start time. + + The program `collect2' works by linking the program once and looking +through the linker output file for symbols with particular names +indicating they are constructor functions. If it finds any, it creates +a new temporary `.c' file containing a table of them, compiles it, and +links the program a second time including that file. + + The actual calls to the constructors are carried out by a subroutine +called `__main', which is called (automatically) at the beginning of +the body of `main' (provided `main' was compiled with GNU CC). Calling +`__main' is necessary, even when compiling C code, to allow linking C +and C++ object code together. (If you use `-nostdlib', you get an +unresolved reference to `__main', since it's defined in the standard +GCC library. Include `-lgcc' at the end of your compiler command line +to resolve this reference.) + + The program `collect2' is installed as `ld' in the directory where +the passes of the compiler are installed. When `collect2' needs to +find the *real* `ld', it tries the following file names: + + * `real-ld' in the directories listed in the compiler's search + directories. + + * `real-ld' in the directories listed in the environment variable + `PATH'. + + * The file specified in the `REAL_LD_FILE_NAME' configuration macro, + if specified. + + * `ld' in the compiler's search directories, except that `collect2' + will not execute itself recursively. + + * `ld' in `PATH'. + + "The compiler's search directories" means all the directories where +`gcc' searches for passes of the compiler. This includes directories +that you specify with `-B'. + + Cross-compilers search a little differently: + + * `real-ld' in the compiler's search directories. + + * `TARGET-real-ld' in `PATH'. + + * The file specified in the `REAL_LD_FILE_NAME' configuration macro, + if specified. + + * `ld' in the compiler's search directories. + + * `TARGET-ld' in `PATH'. + + `collect2' explicitly avoids running `ld' using the file name under +which `collect2' itself was invoked. In fact, it remembers up a list +of such names--in case one copy of `collect2' finds another copy (or +version) of `collect2' installed as `ld' in a second place in the +search path. + + `collect2' searches for the utilities `nm' and `strip' using the +same algorithm as above for `ld'. + +Standard Header File Directories +================================ + + `GCC_INCLUDE_DIR' means the same thing for native and cross. It is +where GNU CC stores its private include files, and also where GNU CC +stores the fixed include files. A cross compiled GNU CC runs +`fixincludes' on the header files in `$(tooldir)/include'. (If the +cross compilation header files need to be fixed, they must be installed +before GNU CC is built. If the cross compilation header files are +already suitable for ANSI C and GNU CC, nothing special need be done). + + `GPLUS_INCLUDE_DIR' means the same thing for native and cross. It +is where `g++' looks first for header files. `libg++' installs only +target independent header files in that directory. + + `LOCAL_INCLUDE_DIR' is used only for a native compiler. It is +normally `/usr/local/include'. GNU CC searches this directory so that +users can install header files in `/usr/local/include'. + + `CROSS_INCLUDE_DIR' is used only for a cross compiler. GNU CC +doesn't install anything there. + + `TOOL_INCLUDE_DIR' is used for both native and cross compilers. It +is the place for other packages to install header files that GNU CC will +use. For a cross-compiler, this is the equivalent of `/usr/include'. +When you build a cross-compiler, `fixincludes' processes any header +files in this directory. + diff --git a/contrib/gcc/config/alpha/config-nt.sed b/contrib/gcc/config/alpha/config-nt.sed new file mode 100644 index 000000000000..a5027bc1882a --- /dev/null +++ b/contrib/gcc/config/alpha/config-nt.sed @@ -0,0 +1,33 @@ +/^Makefile/,/^ rm -f config.run/d +s/rm -f/del/ +s/|| cp/|| copy/ +/^config.status/,/ fi/d +s/config.status//g +s/\/dev\/null/NUL/g +s/$(srcdir)\/c-parse/c-parse/g +s/$(srcdir)\/c-gperf/c-gperf/g +/^multilib.h/ s/multilib/not-multilib/ +/^target=/ c\ +target=winnt3.5 +/^xmake_file=/ d +/^tmake_file=/ d +/^out_file/ c\ +out_file=config/alpha/alpha.c +/^out_object_file/ c\ +out_object_file=alpha.obj +/^md_file/ c\ +md_file=config/alpha/alpha.md +/^tm_file/ c\ +tm_file=config/alpha/winnt.h +/^build_xm_file/ c\ +build_xm_file=config/alpha/xm-winnt.h +/^host_xm_file/ c\ +host_xm_file=config/alpha/xm-winnt.h +/^####target/ i\ +CC = cl \ +CLIB = libc.lib kernel32.lib \ +CFLAGS = -Dalpha -DWIN32 -D_WIN32 -D_ALPHA_ -D_M_ALPHA \\\ + -DALMOST_STDC \ +LDFLAGS = -subsystem:console -entry:mainCRTStartup \\\ + -stack:1000000,1000 \ + diff --git a/contrib/gcc/config/alpha/win-nt.h b/contrib/gcc/config/alpha/win-nt.h new file mode 100644 index 000000000000..cb3d9eb2bd95 --- /dev/null +++ b/contrib/gcc/config/alpha/win-nt.h @@ -0,0 +1,72 @@ +/* Definitions of target machine for GNU compiler, for DEC Alpha + running Windows/NT. + Copyright (C) 1995 Free Software Foundation, Inc. + Contributed by Richard Kenner (kenner@vlsi1.ultra.nyu.edu) + +This file is part of GNU CC. + +GNU CC is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2, or (at your option) +any later version. + +GNU CC is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
