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}.

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.

How the coff backend works

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.

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}
|
134 |
|
|
and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
|
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.

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.

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.

precisely the second symbol for the comdat name.

I have found no documentation on the contents of this section.

Experimentation indicates that the section contains zero or more
|
3948 |
|
|
records, each of which has the following structure:
|
3949 |
|
|
|
3950 |
|
|
- a (four byte) word holding the length of this record, in words,
|
3951 |
|
|
- a word that always seems to be set to "2",
|
3952 |
|
|
- the path to a shared library, null-terminated and then padded
|
3953 |
|
|
to a whole word boundary.
|
3954 |
|
|
|
3955 |
|
|
bfd_assert calls have been added to alert if an attempt is made
|
3956 |
|
|
to write a section which doesn't follow these assumptions. The

|

Reading linenumbers
|
4039 |
|
|
|
4040 |
|
|
Creating the linenumber table is done by reading in the entire
|
4041 |
|
|
coff linenumber table, and creating another table for internal use.
|
4042 |
|
|
|
4043 |
|
|
A coff linenumber table is structured so that each function
|
4044 |
|
|
is marked as having a line number of 0. Each line within the
|
4045 |
|
|
function is an offset from the first line in the function. The
|
4046 |
|
|
base of the line number information for the table is stored in
|
4047 |
|
|
the symbol associated with the function.
|
4048 |
|
|
|
4049 |
|
|
Note: The PE format uses line number 0 for a flag indicating a
|
4050 |
|
|
new source file.
|
4051 |
|
|
|
4052 |
|
|
The information is copied from the external to the internal
|
4053 |
|
|
table, and each symbol which marks a function is marked by
|
4054 |
|
|
pointing its...
|
4055 |

Reading relocations
|
4619 |
|
|
|
4620 |
|
|
Coff relocations are easily transformed into the internal BFD form
|
4621 |
|
|
(@code{arelent}).
|
4622 |
|
|
|
4623 |
|
|
Reading a coff relocation table is done in the following stages:
|
4624 |
|
|
|
4625 |
|
|
o Read the entire coff relocation table into memory.
|
4626 |
|
|
|
4627 |
|
|
o Process each relocation in turn; first swap it from the
|
4628 |
|
|
external to the internal form.
|
4629 |
|
|
|
4630 |
|
|
o Turn the symbol referenced in the relocation's symbol index
|
4631 |
|
|
into a pointer into the canonical symbol table.
|
4632 |
|
|
This table is the same as the one returned by a call to
|
4633 |
|
|
@code{bfd_canonicalize_symtab}. The back end will call that
|
4634 |
|
|
routine and save the result if a canonicalization hasn't been done.
|
4635 |
|
|
|
4636 |
|
|
o The reloc index is turned into a pointer to a howto
|
4637 |
|
|
structure, in a back end specific way. For instance, the 386
|
4638 |
|
|
and 960 use the @code{r_type} to directly produce an index
|
4639 |
|
|
into a howto table vector; the 88k subtracts a number from the
|
4640 |
|
|
@code{r_type} field and creates an addend field.
