28 coff backends
29
9fda1a39
SC		 30 BFD supports a number of different flavours of coff format.
31 The major difference between formats are the sizes and
32 alignments of fields in structures on disk, and the occasional
33 extra field.
34
35 Coff in all its varieties is implimented 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 @code{coff-m88k.c}. This file @code{#include}s
39 @code{coff-m88k.h} which defines the external structure of the
40 coff format for the 88k, and @code{internalcoff.h} which
41 defines the internal structure. @code{coff-m88k.c} also
42 defines pthe relocations used by the 88k format
43 @xref{Relocations}. Then the major portion of coff code is
44 included (@code{coffcode.h}) which defines the methods used to
45 act upon the types defined in @code{coff-m88k.h} and
46 @code{internalcoff.h}.
47
48
49 The Intel i960 processor version of coff is implemented in
50 @code{coff-i960.c}. This file has the same structure as
51 @code{coff-m88k.c}, except that it includes @code{coff-i960.h}
52 rather than @code{coff-m88k.h}.
53
54SUBSECTION
55 Porting To A New Version of Coff
56
9fda1a39
SC		 57 The recommended method is to select from the existing
58 implimentations the version of coff which is most like the one
59 you want to use, for our purposes, we'll say that i386 coff is
60 the one you select, and that your coff flavour is called foo.
61 Copy the @code{i386coff.c} to @code{foocoff.c}, copy
62 @code{../include/i386coff.h} to @code{../include/foocoff.h}
63 and add the lines to @code{targets.c} and @code{Makefile.in}
64 so that your new back end is used. Alter the shapes of the
65 structures in @code{../include/foocoff.h} so that they match
66 what you need. You will probably also have to add
67 @code{#ifdef}s to the code in @code{internalcoff.h} and
68 @code{coffcode.h} if your version of coff is too wild.
69
70 You can verify that your new BFD backend works quite simply by
71 building @code{objdump} from the @code{binutils} directory,
72 and making sure that its version of what's going on at your
73 host systems idea (assuming it has the pretty standard coff
74 dump utility (usually called @code{att-dump} or just
75 @code{dump})) are the same. Then clean up your code, and send
76 what you've done to Cygnus. Then your stuff will be in the
77 next release, and you won't have to keep integrating it.

80 How The Coff Backend Works
81
82SUBSUBSECTION
83 Bit Twiddling
84
9fda1a39
SC		 85 Each flavour of coff supported in BFD has its own header file
86 descibing the external layout of the structures. There is also
87 an internal description of the coff layout (in
07de8e96 88 @code{internalcoff.h}). A major function of the
9fda1a39
SC		 89 coff backend is swapping the bytes and twiddling the bits to
90 translate the external form of the structures into the normal
91 internal form. This is all performed in the
92 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
93 elements are different sizes between different versions of
94 coff, it is the duty of the coff version specific include file
95 to override the definitions of various packing routines in
96 @code{coffcode.h}. Eg the size of line number entry in coff is
97 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
98 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
99 correct one. No doubt, some day someone will find a version of
100 coff which has a varying field size not catered for at the
101 moment. To port BFD, that person will have to add more @code{#defines}.
102 Three of the bit twiddling routines are exported to
103 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
104 and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
105 table on its own, but uses BFD to fix things up. More of the
106 bit twiddlers are exported for @code{gas};
107 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
108 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
109 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
110 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
111 of all the symbol table and reloc drudgery itself, thereby
112 saving the internal BFD overhead, but uses BFD to swap things
113 on the way out, making cross ports much safer. This also
114 allows BFD (and thus the linker) to use the same header files
115 as @code{gas}, which makes one avenue to disaster disappear.
116
117SUBSUBSECTION
118 Symbol Reading
119
9fda1a39
SC		 120 The simple canonical form for symbols used by BFD is not rich
121 enough to keep all the information available in a coff symbol
122 table. The back end gets around this by keeping the original
123 symbol table around, "behind the scenes".
124
125 When a symbol table is requested (through a call to
126 @code{bfd_canonicalize_symtab}, a request gets through to
127 @code{get_normalized_symtab}. This reads the symbol table from
128 the coff file and swaps all the structures inside into the
129 internal form. It also fixes up all the pointers in the table
130 (represented in the file by offsets from the first symbol in
131 the table) into physical pointers to elements in the new
132 internal table. This involves some work since the meanings of
133 fields changes depending upon context; a field that is a
134 pointer to another structure in the symbol table at one moment
135 may be the size in bytes of a structure in the next. Another
136 pass is made over the table. All symbols which mark file names
616ebcfd 137 (<<C_FILE>> symbols) are modified so that the internal
9fda1a39
SC		 138 string points to the value in the auxent (the real filename)
139 rather than the normal text associated with the symbol
140 (@code{".file"}).
141
142 At this time the symbol names are moved around. Coff stores
143 all symbols less than nine characters long physically
144 within the symbol table, longer strings are kept at the end of
145 the file in the string table. This pass moves all strings
146 into memory, and replaces them with pointers to the strings.
147
148
149 The symbol table is massaged once again, this time to create
150 the canonical table used by the BFD application. Each symbol
151 is inspected in turn, and a decision made (using the
152 @code{sclass} field) about the various flags to set in the
153 @code{asymbol} @xref{Symbols}. The generated canonical table
154 shares strings with the hidden internal symbol table.
155
156 Any linenumbers are read from the coff file too, and attached
157 to the symbols which own the functions the linenumbers belong to.
158
159SUBSUBSECTION
160 Symbol Writing
161
9fda1a39
SC		 162 Writing a symbol to a coff file which didn't come from a coff
163 file will lose any debugging information. The @code{asymbol}
164 structure remembers the BFD from which was born, and on output
165 the back end makes sure that the same destination target as
166 source target is present.
167
168 When the symbols have come from a coff file then all the
169 debugging information is preserved.
170
171 Symbol tables are provided for writing to the back end in a
172 vector of pointers to pointers. This allows applications like
173 the linker to accumulate and output large symbol tables
174 without having to do too much byte copying.
175
9fda1a39
SC		 176 This function runs through the provided symbol table and
177 patches each symbol marked as a file place holder
178 (@code{C_FILE}) to point to the next file place holder in the
179 list. It also marks each @code{offset} field in the list with
180 the offset from the first symbol of the current symbol.
181
182 Another function of this procedure is to turn the canonical
183 value form of BFD into the form used by coff. Internally, BFD
184 expects symbol values to be offsets from a section base; so a
185 symbol physically at 0x120, but in a section starting at
186 0x100, would have the value 0x20. Coff expects symbols to
187 contain their final value, so symbols have their values
188 changed at this point to reflect their sum with their owning
189 section. Note that this transformation uses the
190 <<output_section>> field of the @code{asymbol}'s
191 @code{asection} @xref{Sections}.
192
193 o coff_mangle_symbols
616ebcfd 194
9fda1a39
SC		 195 This routine runs though the provided symbol table and uses
196 the offsets generated by the previous pass and the pointers
197 generated when the symbol table was read in to create the
198 structured hierachy required by coff. It changes each pointer
199 to a symbol to an index into the symbol table of the symbol
200 being referenced.
201
202 o coff_write_symbols
616ebcfd 203
9fda1a39
SC		 204 This routine runs through the symbol table and patches up the
205 symbols from their internal form into the coff way, calls the
206 bit twiddlers and writes out the tabel to the file.

3632 Reading Relocations

9fda1a39
SC		 3634 Coff relocations are easily transformed into the internal BFD form
3635 (@code{arelent}).
3636
3637 Reading a coff relocation table is done in the following stages:
3638
3639 o The entire coff relocation table is read into memory.
3640
3641 o Each relocation is processed in turn, first it is swapped from the
3642 external to the internal form.
3643
3644 o The symbol referenced in the relocation's symbol index is
3645 turned intoa pointer into the canonical symbol table. Note
3646 that this table is the same as the one returned by a call to
3647 @code{bfd_canonicalize_symtab}. The back end will call the
3648 routine and save the result if a canonicalization hasn't been done.
3649
3650 o The reloc index is turned into a pointer to a howto
3651 structure, in a back end specific way. For instance, the 386
3652 and 960 use the @code{r_type} to directly produce an index
3653 into a howto table vector; the 88k subtracts a number from the
3654 @code{r_type} field and creates an addend field.
