24 coff backends
25
9fda1a39
SC		 26 BFD supports a number of different flavours of coff format.
27 The major difference between formats are the sizes and
28 alignments of fields in structures on disk, and the occasional
29 extra field.
30
31 Coff in all its varieties is implimented with a few common
32 files and a number of implementation specific files. For
33 example, The 88k bcs coff format is implemented in the file
34 @code{coff-m88k.c}. This file @code{#include}s
35 @code{coff-m88k.h} which defines the external structure of the
36 coff format for the 88k, and @code{internalcoff.h} which
37 defines the internal structure. @code{coff-m88k.c} also
38 defines pthe relocations used by the 88k format
39 @xref{Relocations}. Then the major portion of coff code is
40 included (@code{coffcode.h}) which defines the methods used to
41 act upon the types defined in @code{coff-m88k.h} and
42 @code{internalcoff.h}.
43
44
45 The Intel i960 processor version of coff is implemented in
46 @code{coff-i960.c}. This file has the same structure as
47 @code{coff-m88k.c}, except that it includes @code{coff-i960.h}
48 rather than @code{coff-m88k.h}.
49
50SUBSECTION
51 Porting To A New Version of Coff
52
9fda1a39
SC		 53 The recommended method is to select from the existing
54 implimentations the version of coff which is most like the one
55 you want to use, for our purposes, we'll say that i386 coff is
56 the one you select, and that your coff flavour is called foo.
57 Copy the @code{i386coff.c} to @code{foocoff.c}, copy
58 @code{../include/i386coff.h} to @code{../include/foocoff.h}
59 and add the lines to @code{targets.c} and @code{Makefile.in}
60 so that your new back end is used. Alter the shapes of the
61 structures in @code{../include/foocoff.h} so that they match
62 what you need. You will probably also have to add
63 @code{#ifdef}s to the code in @code{internalcoff.h} and
64 @code{coffcode.h} if your version of coff is too wild.
65
66 You can verify that your new BFD backend works quite simply by
67 building @code{objdump} from the @code{binutils} directory,
68 and making sure that its version of what's going on at your
69 host systems 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
77
78SUBSUBSECTION
79 Bit Twiddling
80
9fda1a39
SC		 81 Each flavour of coff supported in BFD has its own header file
82 descibing the external layout of the structures. There is also
83 an internal description of the coff layout (in
84 @code{internalcoff.h}) file (@code{}). A major function of the
85 coff backend is swapping the bytes and twiddling the bits to
86 translate the external form of the structures into the normal
87 internal form. This is all performed in the
88 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
89 elements are different sizes between different versions of
90 coff, it is the duty of the coff version specific include file
91 to override the definitions of various packing routines in
92 @code{coffcode.h}. Eg the size of line number entry in coff is
93 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
94 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
95 correct one. No doubt, some day someone will find a version of
96 coff which has a varying field size not catered for at the
97 moment. To port BFD, that person will have to add more @code{#defines}.
98 Three of the bit twiddling routines are exported to
99 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
100 and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
101 table on its own, but uses BFD to fix things up. More of the
102 bit twiddlers are exported for @code{gas};
103 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
104 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
105 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
106 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
107 of all the symbol table and reloc drudgery itself, thereby
108 saving the internal BFD overhead, but uses BFD to swap things
109 on the way out, making cross ports much safer. This also
110 allows BFD (and thus the linker) to use the same header files
111 as @code{gas}, which makes one avenue to disaster disappear.
112
113SUBSUBSECTION
114 Symbol Reading
115
9fda1a39
SC		 116 The simple canonical form for symbols used by BFD is not rich
117 enough to keep all the information available in a coff symbol
118 table. The back end gets around this by keeping the original
119 symbol table around, "behind the scenes".
120
121 When a symbol table is requested (through a call to
122 @code{bfd_canonicalize_symtab}, a request gets through to
123 @code{get_normalized_symtab}. This reads the symbol table from
124 the coff file and swaps all the structures inside into the
125 internal form. It also fixes up all the pointers in the table
126 (represented in the file by offsets from the first symbol in
127 the table) into physical pointers to elements in the new
128 internal table. This involves some work since the meanings of
129 fields changes depending upon context; a field that is a
130 pointer to another structure in the symbol table at one moment
131 may be the size in bytes of a structure in the next. Another
132 pass is made over the table. All symbols which mark file names
616ebcfd 133 (<<C_FILE>> symbols) are modified so that the internal
9fda1a39
SC		 134 string points to the value in the auxent (the real filename)
135 rather than the normal text associated with the symbol
136 (@code{".file"}).
137
138 At this time the symbol names are moved around. Coff stores
139 all symbols less than nine characters long physically
140 within the symbol table, longer strings are kept at the end of
141 the file in the string table. This pass moves all strings
142 into memory, and replaces them with pointers to the strings.
143
144
145 The symbol table is massaged once again, this time to create
146 the canonical table used by the BFD application. Each symbol
147 is inspected in turn, and a decision made (using the
148 @code{sclass} field) about the various flags to set in the
149 @code{asymbol} @xref{Symbols}. The generated canonical table
150 shares strings with the hidden internal symbol table.
151
152 Any linenumbers are read from the coff file too, and attached
153 to the symbols which own the functions the linenumbers belong to.
154
155SUBSUBSECTION
156 Symbol Writing
157
9fda1a39
SC		 158 Writing a symbol to a coff file which didn't come from a coff
159 file will lose any debugging information. The @code{asymbol}
160 structure remembers the BFD from which was born, and on output
161 the back end makes sure that the same destination target as
162 source target is present.
163
164 When the symbols have come from a coff file then all the
165 debugging information is preserved.
166
167 Symbol tables are provided for writing to the back end in a
168 vector of pointers to pointers. This allows applications like
169 the linker to accumulate and output large symbol tables
170 without having to do too much byte copying.
171
9fda1a39
SC		 172 This function runs through the provided symbol table and
173 patches each symbol marked as a file place holder
174 (@code{C_FILE}) to point to the next file place holder in the
175 list. It also marks each @code{offset} field in the list with
176 the offset from the first symbol of the current symbol.
177
178 Another function of this procedure is to turn the canonical
179 value form of BFD into the form used by coff. Internally, BFD
180 expects symbol values to be offsets from a section base; so a
181 symbol physically at 0x120, but in a section starting at
182 0x100, would have the value 0x20. Coff expects symbols to
183 contain their final value, so symbols have their values
184 changed at this point to reflect their sum with their owning
185 section. Note that this transformation uses the
186 <<output_section>> field of the @code{asymbol}'s
187 @code{asection} @xref{Sections}.
188
189 o coff_mangle_symbols
616ebcfd 190
9fda1a39
SC		 191 This routine runs though the provided symbol table and uses
192 the offsets generated by the previous pass and the pointers
193 generated when the symbol table was read in to create the
194 structured hierachy required by coff. It changes each pointer
195 to a symbol to an index into the symbol table of the symbol
196 being referenced.
197
198 o coff_write_symbols
616ebcfd 199
9fda1a39
SC		 200 This routine runs through the symbol table and patches up the
201 symbols from their internal form into the coff way, calls the
202 bit twiddlers and writes out the tabel to the file.

3125 Reading Relocations

9fda1a39
SC		 3127 Coff relocations are easily transformed into the internal BFD form
3128 (@code{arelent}).
3129
3130 Reading a coff relocation table is done in the following stages:
3131
3132 o The entire coff relocation table is read into memory.
3133
3134 o Each relocation is processed in turn, first it is swapped from the
3135 external to the internal form.
3136
3137 o The symbol referenced in the relocation's symbol index is
3138 turned intoa pointer into the canonical symbol table. Note
3139 that this table is the same as the one returned by a call to
3140 @code{bfd_canonicalize_symtab}. The back end will call the
3141 routine and save the result if a canonicalization hasn't been done.
3142
3143 o The reloc index is turned into a pointer to a howto
3144 structure, in a back end specific way. For instance, the 386
3145 and 960 use the @code{r_type} to directly produce an index
3146 into a howto table vector; the 88k subtracts a number from the
3147 @code{r_type} field and creates an addend field.
