30 coff backends
31
32 BFD supports a number of different flavours of coff format.
33 The major differences between formats are the sizes and
34 alignments of fields in structures on disk, and the occasional
35 extra field.
36
37 Coff in all its varieties is implemented with a few common
38 files and a number of implementation specific files. For
39 example, The 88k bcs coff format is implemented in the file
40 @file{coff-m88k.c}. This file @code{#include}s
41 @file{coff/m88k.h} which defines the external structure of the
42 coff format for the 88k, and @file{coff/internal.h} which
43 defines the internal structure. @file{coff-m88k.c} also
44 defines the relocations used by the 88k format
45 @xref{Relocations}.
46
47 The Intel i960 processor version of coff is implemented in
48 @file{coff-i960.c}. This file has the same structure as
49 @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
50 rather than @file{coff-m88k.h}.
51
52SUBSECTION
53 Porting to a new version of coff
54
55 The recommended method is to select from the existing
56 implementations the version of coff which is most like the one
57 you want to use. For example, we'll say that i386 coff is
58 the one you select, and that your coff flavour is called foo.
59 Copy @file{i386coff.c} to @file{foocoff.c}, copy
60 @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
61 and add the lines to @file{targets.c} and @file{Makefile.in}
62 so that your new back end is used. Alter the shapes of the
63 structures in @file{../include/coff/foo.h} so that they match
64 what you need. You will probably also have to add
65 @code{#ifdef}s to the code in @file{coff/internal.h} and
66 @file{coffcode.h} if your version of coff is too wild.
67
68 You can verify that your new BFD backend works quite simply by
69 building @file{objdump} from the @file{binutils} directory,
70 and making sure that its version of what's going on and your
71 host system's idea (assuming it has the pretty standard coff
72 dump utility, usually called @code{att-dump} or just
73 @code{dump}) are the same. Then clean up your code, and send
74 what you've done to Cygnus. Then your stuff will be in the
75 next release, and you won't have to keep integrating it.
76
77SUBSECTION
78 How the coff backend works
79
80SUBSUBSECTION
81 File layout
82
83 The Coff backend is split into generic routines that are
84 applicable to any Coff target and routines that are specific
85 to a particular target. The target-specific routines are
86 further split into ones which are basically the same for all
87 Coff targets except that they use the external symbol format
88 or use different values for certain constants.
89
90 The generic routines are in @file{coffgen.c}. These routines
91 work for any Coff target. They use some hooks into the target
92 specific code; the hooks are in a @code{bfd_coff_backend_data}
93 structure, one of which exists for each target.
94
95 The essentially similar target-specific routines are in
96 @file{coffcode.h}. This header file includes executable C code.
97 The various Coff targets first include the appropriate Coff
98 header file, make any special defines that are needed, and
99 then include @file{coffcode.h}.
100
101 Some of the Coff targets then also have additional routines in
102 the target source file itself.
103
104 For example, @file{coff-i960.c} includes
105 @file{coff/internal.h} and @file{coff/i960.h}. It then
106 defines a few constants, such as @code{I960}, and includes
107 @file{coffcode.h}. Since the i960 has complex relocation
108 types, @file{coff-i960.c} also includes some code to
109 manipulate the i960 relocs. This code is not in
110 @file{coffcode.h} because it would not be used by any other
111 target.
112
113SUBSUBSECTION
114 Bit twiddling
115
116 Each flavour of coff supported in BFD has its own header file
117 describing the external layout of the structures. There is also
118 an internal description of the coff layout, in
119 @file{coff/internal.h}. A major function of the
120 coff backend is swapping the bytes and twiddling the bits to
121 translate the external form of the structures into the normal
122 internal form. This is all performed in the
123 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
124 elements are different sizes between different versions of
125 coff; it is the duty of the coff version specific include file
126 to override the definitions of various packing routines in
127 @file{coffcode.h}. E.g., the size of line number entry in coff is
128 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
129 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
130 correct one. No doubt, some day someone will find a version of
131 coff which has a varying field size not catered to at the
132 moment. To port BFD, that person will have to add more @code{#defines}.
133 Three of the bit twiddling routines are exported to
134 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
00692651 135 and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
252b5132
RH
136 table on its own, but uses BFD to fix things up. More of the
137 bit twiddlers are exported for @code{gas};
138 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
139 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
140 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
141 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
142 of all the symbol table and reloc drudgery itself, thereby
143 saving the internal BFD overhead, but uses BFD to swap things
144 on the way out, making cross ports much safer. Doing so also
145 allows BFD (and thus the linker) to use the same header files
146 as @code{gas}, which makes one avenue to disaster disappear.
147
148SUBSUBSECTION
149 Symbol reading
150
151 The simple canonical form for symbols used by BFD is not rich
152 enough to keep all the information available in a coff symbol
153 table. The back end gets around this problem by keeping the original
154 symbol table around, "behind the scenes".
155
156 When a symbol table is requested (through a call to
157 @code{bfd_canonicalize_symtab}), a request gets through to
158 @code{coff_get_normalized_symtab}. This reads the symbol table from
159 the coff file and swaps all the structures inside into the
160 internal form. It also fixes up all the pointers in the table
161 (represented in the file by offsets from the first symbol in
162 the table) into physical pointers to elements in the new
163 internal table. This involves some work since the meanings of
164 fields change depending upon context: a field that is a
165 pointer to another structure in the symbol table at one moment
166 may be the size in bytes of a structure at the next. Another
167 pass is made over the table. All symbols which mark file names
168 (<<C_FILE>> symbols) are modified so that the internal
169 string points to the value in the auxent (the real filename)
170 rather than the normal text associated with the symbol
171 (@code{".file"}).
172
173 At this time the symbol names are moved around. Coff stores
174 all symbols less than nine characters long physically
175 within the symbol table; longer strings are kept at the end of
176 the file in the string table. This pass moves all strings
177 into memory and replaces them with pointers to the strings.
178
252b5132
RH
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
ed781d5d 228 structured hierarchy required by coff. It changes each pointer
252b5132
RH
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.

4992 Reading relocations
4993
4994 Coff relocations are easily transformed into the internal BFD form
4995 (@code{arelent}).
4996
4997 Reading a coff relocation table is done in the following stages:
4998
4999 o Read the entire coff relocation table into memory.
5000
5001 o Process each relocation in turn; first swap it from the
5002 external to the internal form.
5003
5004 o Turn the symbol referenced in the relocation's symbol index
5005 into a pointer into the canonical symbol table.
5006 This table is the same as the one returned by a call to
5007 @code{bfd_canonicalize_symtab}. The back end will call that
5008 routine and save the result if a canonicalization hasn't been done.
5009
5010 o The reloc index is turned into a pointer to a howto
5011 structure, in a back end specific way. For instance, the 386
5012 and 960 use the @code{r_type} to directly produce an index
5013 into a howto table vector; the 88k subtracts a number from the
5014 @code{r_type} field and creates an addend field.
