29 coff backends
30
31 BFD supports a number of different flavours of coff format.
32 The major differences between formats are the sizes and
33 alignments of fields in structures on disk, and the occasional
34 extra field.
35
36 Coff in all its varieties is implemented with a few common
37 files and a number of implementation specific files. For
38 example, The 88k bcs coff format is implemented in the file
39 @file{coff-m88k.c}. This file @code{#include}s
40 @file{coff/m88k.h} which defines the external structure of the
41 coff format for the 88k, and @file{coff/internal.h} which
42 defines the internal structure. @file{coff-m88k.c} also
43 defines the relocations used by the 88k format
44 @xref{Relocations}.
45
46 The Intel i960 processor version of coff is implemented in
47 @file{coff-i960.c}. This file has the same structure as
48 @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
49 rather than @file{coff-m88k.h}.
50
51SUBSECTION
52 Porting to a new version of coff
53
54 The recommended method is to select from the existing
55 implementations the version of coff which is most like the one
56 you want to use. For example, we'll say that i386 coff is
57 the one you select, and that your coff flavour is called foo.
58 Copy @file{i386coff.c} to @file{foocoff.c}, copy
59 @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
60 and add the lines to @file{targets.c} and @file{Makefile.in}
61 so that your new back end is used. Alter the shapes of the
62 structures in @file{../include/coff/foo.h} so that they match
63 what you need. You will probably also have to add
64 @code{#ifdef}s to the code in @file{coff/internal.h} and
65 @file{coffcode.h} if your version of coff is too wild.
66
67 You can verify that your new BFD backend works quite simply by
68 building @file{objdump} from the @file{binutils} directory,
69 and making sure that its version of what's going on and your
70 host system's idea (assuming it has the pretty standard coff
71 dump utility, usually called @code{att-dump} or just
72 @code{dump}) are the same. Then clean up your code, and send
73 what you've done to Cygnus. Then your stuff will be in the
74 next release, and you won't have to keep integrating it.
75
76SUBSECTION
77 How the coff backend works
78
79SUBSUBSECTION
80 File layout
81
82 The Coff backend is split into generic routines that are
83 applicable to any Coff target and routines that are specific
84 to a particular target. The target-specific routines are
85 further split into ones which are basically the same for all
86 Coff targets except that they use the external symbol format
87 or use different values for certain constants.
88
89 The generic routines are in @file{coffgen.c}. These routines
90 work for any Coff target. They use some hooks into the target
91 specific code; the hooks are in a @code{bfd_coff_backend_data}
92 structure, one of which exists for each target.
93
94 The essentially similar target-specific routines are in
95 @file{coffcode.h}. This header file includes executable C code.
96 The various Coff targets first include the appropriate Coff
97 header file, make any special defines that are needed, and
98 then include @file{coffcode.h}.
99
100 Some of the Coff targets then also have additional routines in
101 the target source file itself.
102
103 For example, @file{coff-i960.c} includes
104 @file{coff/internal.h} and @file{coff/i960.h}. It then
105 defines a few constants, such as @code{I960}, and includes
106 @file{coffcode.h}. Since the i960 has complex relocation
107 types, @file{coff-i960.c} also includes some code to
108 manipulate the i960 relocs. This code is not in
109 @file{coffcode.h} because it would not be used by any other
110 target.
111
112SUBSUBSECTION
113 Bit twiddling
114
115 Each flavour of coff supported in BFD has its own header file
116 describing the external layout of the structures. There is also
117 an internal description of the coff layout, in
118 @file{coff/internal.h}. A major function of the
119 coff backend is swapping the bytes and twiddling the bits to
120 translate the external form of the structures into the normal
121 internal form. This is all performed in the
122 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
123 elements are different sizes between different versions of
124 coff; it is the duty of the coff version specific include file
125 to override the definitions of various packing routines in
126 @file{coffcode.h}. E.g., the size of line number entry in coff is
127 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
128 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
129 correct one. No doubt, some day someone will find a version of
130 coff which has a varying field size not catered to at the
131 moment. To port BFD, that person will have to add more @code{#defines}.
132 Three of the bit twiddling routines are exported to
133 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
00692651 134 and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
252b5132
RH
135 table on its own, but uses BFD to fix things up. More of the
136 bit twiddlers are exported for @code{gas};
137 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
138 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
139 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
140 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
141 of all the symbol table and reloc drudgery itself, thereby
142 saving the internal BFD overhead, but uses BFD to swap things
143 on the way out, making cross ports much safer. Doing so also
144 allows BFD (and thus the linker) to use the same header files
145 as @code{gas}, which makes one avenue to disaster disappear.
146
147SUBSUBSECTION
148 Symbol reading
149
150 The simple canonical form for symbols used by BFD is not rich
151 enough to keep all the information available in a coff symbol
152 table. The back end gets around this problem by keeping the original
153 symbol table around, "behind the scenes".
154
155 When a symbol table is requested (through a call to
156 @code{bfd_canonicalize_symtab}), a request gets through to
157 @code{coff_get_normalized_symtab}. This reads the symbol table from
158 the coff file and swaps all the structures inside into the
159 internal form. It also fixes up all the pointers in the table
160 (represented in the file by offsets from the first symbol in
161 the table) into physical pointers to elements in the new
162 internal table. This involves some work since the meanings of
163 fields change depending upon context: a field that is a
164 pointer to another structure in the symbol table at one moment
165 may be the size in bytes of a structure at the next. Another
166 pass is made over the table. All symbols which mark file names
167 (<<C_FILE>> symbols) are modified so that the internal
168 string points to the value in the auxent (the real filename)
169 rather than the normal text associated with the symbol
170 (@code{".file"}).
171
172 At this time the symbol names are moved around. Coff stores
173 all symbols less than nine characters long physically
174 within the symbol table; longer strings are kept at the end of
175 the file in the string table. This pass moves all strings
176 into memory and replaces them with pointers to the strings.
177
178
179 The symbol table is massaged once again, this time to create
180 the canonical table used by the BFD application. Each symbol
181 is inspected in turn, and a decision made (using the
182 @code{sclass} field) about the various flags to set in the
183 @code{asymbol}. @xref{Symbols}. The generated canonical table
184 shares strings with the hidden internal symbol table.
185
186 Any linenumbers are read from the coff file too, and attached
187 to the symbols which own the functions the linenumbers belong to.
188
189SUBSUBSECTION
190 Symbol writing
191
192 Writing a symbol to a coff file which didn't come from a coff
193 file will lose any debugging information. The @code{asymbol}
194 structure remembers the BFD from which the symbol was taken, and on
195 output the back end makes sure that the same destination target as
196 source target is present.
197
198 When the symbols have come from a coff file then all the
199 debugging information is preserved.
200
201 Symbol tables are provided for writing to the back end in a
202 vector of pointers to pointers. This allows applications like
203 the linker to accumulate and output large symbol tables
204 without having to do too much byte copying.
205
206 This function runs through the provided symbol table and
207 patches each symbol marked as a file place holder
208 (@code{C_FILE}) to point to the next file place holder in the
209 list. It also marks each @code{offset} field in the list with
210 the offset from the first symbol of the current symbol.
211
212 Another function of this procedure is to turn the canonical
213 value form of BFD into the form used by coff. Internally, BFD
214 expects symbol values to be offsets from a section base; so a
215 symbol physically at 0x120, but in a section starting at
216 0x100, would have the value 0x20. Coff expects symbols to
217 contain their final value, so symbols have their values
218 changed at this point to reflect their sum with their owning
219 section. This transformation uses the
220 <<output_section>> field of the @code{asymbol}'s
221 @code{asection} @xref{Sections}.
222
223 o <<coff_mangle_symbols>>
224
225 This routine runs though the provided symbol table and uses
226 the offsets generated by the previous pass and the pointers
227 generated when the symbol table was read in to create the
228 structured hierachy required by coff. It changes each pointer
229 to a symbol into the index into the symbol table of the asymbol.
230
231 o <<coff_write_symbols>>
232
233 This routine runs through the symbol table and patches up the
234 symbols from their internal form into the coff way, calls the
235 bit twiddlers, and writes out the table to the file.

4584 Reading relocations
4585
4586 Coff relocations are easily transformed into the internal BFD form
4587 (@code{arelent}).
4588
4589 Reading a coff relocation table is done in the following stages:
4590
4591 o Read the entire coff relocation table into memory.
4592
4593 o Process each relocation in turn; first swap it from the
4594 external to the internal form.
4595
4596 o Turn the symbol referenced in the relocation's symbol index
4597 into a pointer into the canonical symbol table.
4598 This table is the same as the one returned by a call to
4599 @code{bfd_canonicalize_symtab}. The back end will call that
4600 routine and save the result if a canonicalization hasn't been done.
4601
4602 o The reloc index is turned into a pointer to a howto
4603 structure, in a back end specific way. For instance, the 386
4604 and 960 use the @code{r_type} to directly produce an index
4605 into a howto table vector; the 88k subtracts a number from the
4606 @code{r_type} field and creates an addend field.
