22 Most of this hacked by Steve Chamberlain,
30 BFD supports a number of different flavours of coff format.
31 The major differences between formats are the sizes and
32 alignments of fields in structures on disk, and the occasional
35 Coff in all its varieties is implemented with a few common
36 files and a number of implementation specific files. For
37 example, The 88k bcs coff format is implemented in the file
38 @file{coff-m88k.c}. This file @code{#include}s
39 @file{coff/m88k.h} which defines the external structure of the
40 coff format for the 88k, and @file{coff/internal.h} which
41 defines the internal structure. @file{coff-m88k.c} also
42 defines the relocations used by the 88k format
45 The Intel i960 processor version of coff is implemented in
46 @file{coff-i960.c}. This file has the same structure as
47 @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
48 rather than @file{coff-m88k.h}.
51 Porting to a new version of coff
53 The recommended method is to select from the existing
54 implementations the version of coff which is most like the one
55 you want to use. For example, we'll say that i386 coff is
56 the one you select, and that your coff flavour is called foo.
57 Copy @file{i386coff.c} to @file{foocoff.c}, copy
58 @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
59 and add the lines to @file{targets.c} and @file{Makefile.in}
60 so that your new back end is used. Alter the shapes of the
61 structures in @file{../include/coff/foo.h} so that they match
62 what you need. You will probably also have to add
63 @code{#ifdef}s to the code in @file{coff/internal.h} and
64 @file{coffcode.h} if your version of coff is too wild.
66 You can verify that your new BFD backend works quite simply by
67 building @file{objdump} from the @file{binutils} directory,
68 and making sure that its version of what's going on and your
69 host system's idea (assuming it has the pretty standard coff
70 dump utility, usually called @code{att-dump} or just
71 @code{dump}) are the same. Then clean up your code, and send
72 what you've done to Cygnus. Then your stuff will be in the
73 next release, and you won't have to keep integrating it.
76 How the coff backend works
81 The Coff backend is split into generic routines that are
82 applicable to any Coff target and routines that are specific
83 to a particular target. The target-specific routines are
84 further split into ones which are basically the same for all
85 Coff targets except that they use the external symbol format
86 or use different values for certain constants.
88 The generic routines are in @file{coffgen.c}. These routines
89 work for any Coff target. They use some hooks into the target
90 specific code; the hooks are in a @code{bfd_coff_backend_data}
91 structure, one of which exists for each target.
93 The essentially similar target-specific routines are in
94 @file{coffcode.h}. This header file includes executable C code.
95 The various Coff targets first include the appropriate Coff
96 header file, make any special defines that are needed, and
97 then include @file{coffcode.h}.
99 Some of the Coff targets then also have additional routines in
100 the target source file itself.
102 For example, @file{coff-i960.c} includes
103 @file{coff/internal.h} and @file{coff/i960.h}. It then
104 defines a few constants, such as @code{I960}, and includes
105 @file{coffcode.h}. Since the i960 has complex relocation
106 types, @file{coff-i960.c} also includes some code to
107 manipulate the i960 relocs. This code is not in
108 @file{coffcode.h} because it would not be used by any other
114 Each flavour of coff supported in BFD has its own header file
115 describing the external layout of the structures. There is also
116 an internal description of the coff layout, in
117 @file{coff/internal.h}. A major function of the
118 coff backend is swapping the bytes and twiddling the bits to
119 translate the external form of the structures into the normal
120 internal form. This is all performed in the
121 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
122 elements are different sizes between different versions of
123 coff; it is the duty of the coff version specific include file
124 to override the definitions of various packing routines in
125 @file{coffcode.h}. E.g., the size of line number entry in coff is
126 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
127 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
128 correct one. No doubt, some day someone will find a version of
129 coff which has a varying field size not catered to at the
130 moment. To port BFD, that person will have to add more @code{#defines}.
131 Three of the bit twiddling routines are exported to
132 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
133 and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
134 table on its own, but uses BFD to fix things up. More of the
135 bit twiddlers are exported for @code{gas};
136 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
137 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
138 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
139 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
140 of all the symbol table and reloc drudgery itself, thereby
141 saving the internal BFD overhead, but uses BFD to swap things
142 on the way out, making cross ports much safer. Doing so also
143 allows BFD (and thus the linker) to use the same header files
144 as @code{gas}, which makes one avenue to disaster disappear.
149 The simple canonical form for symbols used by BFD is not rich
150 enough to keep all the information available in a coff symbol
151 table. The back end gets around this problem by keeping the original
152 symbol table around, "behind the scenes".
154 When a symbol table is requested (through a call to
155 @code{bfd_canonicalize_symtab}), a request gets through to
156 @code{coff_get_normalized_symtab}. This reads the symbol table from
157 the coff file and swaps all the structures inside into the
158 internal form. It also fixes up all the pointers in the table
159 (represented in the file by offsets from the first symbol in
160 the table) into physical pointers to elements in the new
161 internal table. This involves some work since the meanings of
162 fields change depending upon context: a field that is a
163 pointer to another structure in the symbol table at one moment
164 may be the size in bytes of a structure at the next. Another
165 pass is made over the table. All symbols which mark file names
166 (<<C_FILE>> symbols) are modified so that the internal
167 string points to the value in the auxent (the real filename)
168 rather than the normal text associated with the symbol
171 At this time the symbol names are moved around. Coff stores
172 all symbols less than nine characters long physically
173 within the symbol table; longer strings are kept at the end of
174 the file in the string table. This pass moves all strings
175 into memory and replaces them with pointers to the strings.
178 The symbol table is massaged once again, this time to create
179 the canonical table used by the BFD application. Each symbol
180 is inspected in turn, and a decision made (using the
181 @code{sclass} field) about the various flags to set in the
182 @code{asymbol}. @xref{Symbols}. The generated canonical table
183 shares strings with the hidden internal symbol table.
185 Any linenumbers are read from the coff file too, and attached
186 to the symbols which own the functions the linenumbers belong to.
191 Writing a symbol to a coff file which didn't come from a coff
192 file will lose any debugging information. The @code{asymbol}
193 structure remembers the BFD from which the symbol was taken, and on
194 output the back end makes sure that the same destination target as
195 source target is present.
197 When the symbols have come from a coff file then all the
198 debugging information is preserved.
200 Symbol tables are provided for writing to the back end in a
201 vector of pointers to pointers. This allows applications like
202 the linker to accumulate and output large symbol tables
203 without having to do too much byte copying.
205 This function runs through the provided symbol table and
206 patches each symbol marked as a file place holder
207 (@code{C_FILE}) to point to the next file place holder in the
208 list. It also marks each @code{offset} field in the list with
209 the offset from the first symbol of the current symbol.
211 Another function of this procedure is to turn the canonical
212 value form of BFD into the form used by coff. Internally, BFD
213 expects symbol values to be offsets from a section base; so a
214 symbol physically at 0x120, but in a section starting at
215 0x100, would have the value 0x20. Coff expects symbols to
216 contain their final value, so symbols have their values
217 changed at this point to reflect their sum with their owning
218 section. This transformation uses the
219 <<output_section>> field of the @code{asymbol}'s
220 @code{asection} @xref{Sections}.
222 o <<coff_mangle_symbols>>
224 This routine runs though the provided symbol table and uses
225 the offsets generated by the previous pass and the pointers
226 generated when the symbol table was read in to create the
227 structured hierachy required by coff. It changes each pointer
228 to a symbol into the index into the symbol table of the asymbol.
230 o <<coff_write_symbols>>
232 This routine runs through the symbol table and patches up the
233 symbols from their internal form into the coff way, calls the
234 bit twiddlers, and writes out the table to the file.
243 The hidden information for an <<asymbol>> is described in a
244 <<combined_entry_type>>:
248 .typedef struct coff_ptr_struct
251 . {* Remembers the offset from the first symbol in the file for
252 . this symbol. Generated by coff_renumber_symbols. *}

3087 Coff relocations are easily transformed into the internal BFD form
3090 Reading a coff relocation table is done in the following stages:
3092 o Read the entire coff relocation table into memory.
3094 o Process each relocation in turn; first swap it from the
3095 external to the internal form.
3097 o Turn the symbol referenced in the relocation's symbol index
3098 into a pointer into the canonical symbol table.
3099 This table is the same as the one returned by a call to
3100 @code{bfd_canonicalize_symtab}. The back end will call that
3101 routine and save the result if a canonicalization hasn't been done.
3103 o The reloc index is turned into a pointer to a howto
3104 structure, in a back end specific way. For instance, the 386
3105 and 960 use the @code{r_type} to directly produce an index
3106 into a howto table vector; the 88k subtracts a number from the
3107 @code{r_type} field and creates an addend field.
