For + example, The 88k bcs coff format is implemented in the file + @file{coff-m88k.c}. This file @code{#include}s + @file{coff/m88k.h} which defines the external structure of the + coff format for the 88k, and @file{coff/internal.h} which + defines the internal structure. @file{coff-m88k.c} also + defines the relocations used by the 88k format + @xref{Relocations}. + + The Intel i960 processor version of coff is implemented in + @file{coff-i960.c}. This file has the same structure as + @file{coff-m88k.c}, except that it includes @file{coff/i960.h} + rather than @file{coff-m88k.h}. + +SUBSECTION + Porting to a new version of coff + + The recommended method is to select from the existing + implementations the version of coff which is most like the one + you want to use. For example, we'll say that i386 coff is + the one you select, and that your coff flavour is called foo. + Copy @file{i386coff.c} to @file{foocoff.c}, copy + @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, + and add the lines to @file{targets.c} and @file{Makefile.in} + so that your new back end is used. Alter the shapes of the + structures in @file{../include/coff/foo.h} so that they match + what you need. You will probably also have to add + @code{#ifdef}s to the code in @file{coff/internal.h} and + @file{coffcode.h} if your version of coff is too wild. + + You can verify that your new BFD backend works quite simply by + building @file{objdump} from the @file{binutils} directory, + and making sure that its version of what's going on and your + host system's idea (assuming it has the pretty standard coff + dump utility, usually called @code{att-dump} or just + @code{dump}) are the same. Then clean up your code, and send + what you've done to Cygnus. Then your stuff will be in the + next release, and you won't have to keep integrating it. + +SUBSECTION + How the coff backend works + +SUBSUBSECTION + File layout + + The Coff backend is split into generic routines that are + applicable to any Coff target and routines that are specific + to a particular target. The target-specific routines are + further split into ones which are basically the same for all + Coff targets except that they use the external symbol format + or use different values for certain constants. + + The generic routines are in @file{coffgen.c}. These routines + work for any Coff target. They use some hooks into the target + specific code; the hooks are in a @code{bfd_coff_backend_data} + structure, one of which exists for each target. + + The essentially similar target-specific routines are in + @file{coffcode.h}. This header file includes executable C code. + The various Coff targets first include the appropriate Coff + header file, make any special defines that are needed, and + then include @file{coffcode.h}. + + Some of the Coff targets then also have additional routines in + the target source file itself. + + For example, @file{coff-i960.c} includes + @file{coff/internal.h} and @file{coff/i960.h}. It then + defines a few constants, such as @code{I960}, and includes + @file{coffcode.h}. Since the i960 has complex relocation + types, @file{coff-i960.c} also includes some code to + manipulate the i960 relocs. This code is not in + @file{coffcode.h} because it would not be used by any other + target. + +SUBSUBSECTION + Bit twiddling + + Each flavour of coff supported in BFD has its own header file + describing the external layout of the structures. There is also + an internal description of the coff layout, in + @file{coff/internal.h}. A major function of the + coff backend is swapping the bytes and twiddling the bits to + translate the external form of the structures into the normal + internal form. This is all performed in the + @code{bfd_swap}_@i{thing}_@i{direction} routines. Some + elements are different sizes between different versions of + coff; it is the duty of the coff version specific include file + to override the definitions of various packing routines in + @file{coffcode.h}. E.g., the size of line number entry in coff is + sometimes 16 bits, and sometimes 32 bits. @code{#define}ing + @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the + correct one. No doubt, some day someone will find a version of + coff which has a varying field size not catered to at the + moment. To port BFD, that person will have to add more @code{#defines}. + Three of the bit twiddling routines are exported to + @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} + and @code{coff_swap_linno_in}. @code{GDB} reads the symbol + table on its own, but uses BFD to fix things up. More of the + bit twiddlers are exported for @code{gas}; + @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, + @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, + @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, + @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track + of all the symbol table and reloc drudgery itself, thereby + saving the internal BFD overhead, but uses BFD to swap things + on the way out, making cross ports much safer. Doing so also + allows BFD (and thus the linker) to use the same header files + as @code{gas}, which makes one avenue to disaster disappear. + +SUBSUBSECTION + Symbol reading + + The simple canonical form for symbols used by BFD is not rich + enough to keep all the information available in a coff symbol + table. The back end gets around this problem by keeping the original + symbol table around, "behind the scenes". + + When a symbol table is requested (through a call to + @code{bfd_canonicalize_symtab}), a request gets through to + @code{coff_get_normalized_symtab}. This reads the symbol table from + the coff file and swaps all the structures inside into the + internal form. It also fixes up all the pointers in the table + (represented in the file by offsets from the first symbol in + the table) into physical pointers to elements in the new + internal table. This involves some work since the meanings of + fields change depending upon context: a field that is a + pointer to another structure in the symbol table at one moment + may be the size in bytes of a structure at the next. Another + pass is made over the table. All symbols which mark file names + (<<C_FILE>> symbols) are modified so that the internal + string points to the value in the auxent (the real filename) + rather than the normal text associated with the symbol + (@code{".file"}). + + At this time the symbol names are moved around. Coff stores + all symbols less than nine characters long physically + within the symbol table; longer strings are kept at the end of + the file in the string table. This pass moves all strings + into memory and replaces them with pointers to the strings. + + + The symbol table is massaged once again, this time to create + the canonical table used by the BFD application. Each symbol + is inspected in turn, and a decision made (using the + @code{sclass} field) about the various flags to set in the + @code{asymbol}. @xref{Symbols}. The generated canonical table + shares strings with the hidden internal symbol table. + + Any linenumbers are read from the coff file too, and attached + to the symbols which own the functions the linenumbers belong to. + +SUBSUBSECTION + Symbol writing + + Writing a symbol to a coff file which didn't come from a coff + file will lose any debugging information. The @code{asymbol} + structure remembers the BFD from which the symbol was taken, and on + output the back end makes sure that the same destination target as + source target is present. + + When the symbols have come from a coff file then all the + debugging information is preserved. + + Symbol tables are provided for writing to the back end in a + vector of pointers to pointers. This allows applications like + the linker to accumulate and output large symbol tables + without having to do too much byte copying. + + This function runs through the provided symbol table and + patches each symbol marked as a file place holder + (@code{C_FILE}) to point to the next file place holder in the + list. It also marks each @code{offset} field in the list with + the offset from the first symbol of the current symbol. + + Another function of this procedure is to turn the canonical + value form of BFD into the form used by coff. Internally, BFD + expects symbol values to be offsets from a section base; so a + symbol physically at 0x120, but in a section starting at + 0x100, would have the value 0x20. Coff expects symbols to + contain their final value, so symbols have their values + changed at this point to reflect their sum with their owning + section. This transformation uses the + <<output_section>> field of the @code{asymbol}'s + @code{asection} @xref{Sections}. + + o <<coff_mangle_symbols>> + + This routine runs though the provided symbol table and uses + the offsets generated by the previous pass and the pointers + generated when the symbol table was read in to create the + structured hierachy required by coff. It changes each pointer + to a symbol into the index into the symbol table of the asymbol. + + o <<coff_write_symbols>> + + This routine runs through the symbol table and patches up the + symbols from their internal form into the coff way, calls the + bit twiddlers, and writes out the table to the file. + +*/ + +/* +INTERNAL_DEFINITION + coff_symbol_type + +DESCRIPTION + The hidden information for an <<asymbol>> is described in a + <<combined_entry_type>>: + +CODE_FRAGMENT +. +.typedef struct coff_ptr_struct +.{ +. +. {* Remembers the offset from the first symbol in the file for +. this symbol.
