26 | coff backends | |
27 | ||
28 | BFD supports a number of different flavours of coff format. | |
29 | The major differences between formats are the sizes and | |
30 | alignments of fields in structures on disk, and the occasional | |
31 | extra field. | |
32 | ||
33 | Coff in all its varieties is implemented with a few common | |
34 | files and a number of implementation specific files. For | |
c2bf1eec AM |
35 | example, the i386 coff format is implemented in the file |
36 | @file{coff-i386.c}. This file @code{#include}s | |
37 | @file{coff/i386.h} which defines the external structure of the | |
38 | coff format for the i386, and @file{coff/internal.h} which | |
39 | defines the internal structure. @file{coff-i386.c} also | |
40 | defines the relocations used by the i386 coff format | |
252b5132 RH |
41 | @xref{Relocations}. |

44 | Porting to a new version of coff | |
45 | ||
46 | The recommended method is to select from the existing | |
47 | implementations the version of coff which is most like the one | |
48 | you want to use. For example, we'll say that i386 coff is | |
49 | the one you select, and that your coff flavour is called foo. | |
50 | Copy @file{i386coff.c} to @file{foocoff.c}, copy | |
51 | @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, | |
52 | and add the lines to @file{targets.c} and @file{Makefile.in} | |
53 | so that your new back end is used. Alter the shapes of the | |
54 | structures in @file{../include/coff/foo.h} so that they match | |
55 | what you need. You will probably also have to add | |
56 | @code{#ifdef}s to the code in @file{coff/internal.h} and | |
57 | @file{coffcode.h} if your version of coff is too wild. | |
58 | ||
59 | You can verify that your new BFD backend works quite simply by | |
60 | building @file{objdump} from the @file{binutils} directory, | |
61 | and making sure that its version of what's going on and your | |
62 | host system's idea (assuming it has the pretty standard coff | |
63 | dump utility, usually called @code{att-dump} or just | |
64 | @code{dump}) are the same. Then clean up your code, and send | |
65 | what you've done to Cygnus. Then your stuff will be in the | |
66 | next release, and you won't have to keep integrating it. | |
67 | ||
68 | SUBSECTION | |
69 | How the coff backend works | |
70 | ||
71 | SUBSUBSECTION | |
72 | File layout | |
73 | ||
74 | The Coff backend is split into generic routines that are | |
75 | applicable to any Coff target and routines that are specific | |
76 | to a particular target. The target-specific routines are | |
77 | further split into ones which are basically the same for all | |
78 | Coff targets except that they use the external symbol format | |
79 | or use different values for certain constants. | |
80 | ||
81 | The generic routines are in @file{coffgen.c}. These routines | |
82 | work for any Coff target. They use some hooks into the target | |
83 | specific code; the hooks are in a @code{bfd_coff_backend_data} | |
84 | structure, one of which exists for each target. | |
85 | ||
86 | The essentially similar target-specific routines are in | |
87 | @file{coffcode.h}. This header file includes executable C code. | |
88 | The various Coff targets first include the appropriate Coff | |
89 | header file, make any special defines that are needed, and | |
90 | then include @file{coffcode.h}. | |
91 | ||
92 | Some of the Coff targets then also have additional routines in | |
93 | the target source file itself. | |
94 | ||

95 | SUBSUBSECTION |
96 | Coff long section names | |
97 | ||
98 | In the standard Coff object format, section names are limited to | |
99 | the eight bytes available in the @code{s_name} field of the | |
100 | @code{SCNHDR} section header structure. The format requires the | |
101 | field to be NUL-padded, but not necessarily NUL-terminated, so | |
102 | the longest section names permitted are a full eight characters. | |
103 | ||
104 | The Microsoft PE variants of the Coff object file format add | |
105 | an extension to support the use of long section names. This | |
68ffbac6 | 106 | extension is defined in section 4 of the Microsoft PE/COFF |
88183869 DK |
107 | specification (rev 8.1). If a section name is too long to fit |
108 | into the section header's @code{s_name} field, it is instead | |
109 | placed into the string table, and the @code{s_name} field is | |
68ffbac6 | 110 | filled with a slash ("/") followed by the ASCII decimal |
88183869 DK |
111 | representation of the offset of the full name relative to the |
112 | string table base. | |
113 | ||
114 | Note that this implies that the extension can only be used in object | |
115 | files, as executables do not contain a string table. The standard | |
116 | specifies that long section names from objects emitted into executable | |
117 | images are to be truncated. | |
118 | ||
119 | However, as a GNU extension, BFD can generate executable images | |
120 | that contain a string table and long section names. This | |
121 | would appear to be technically valid, as the standard only says | |
122 | that Coff debugging information is deprecated, not forbidden, | |
123 | and in practice it works, although some tools that parse PE files | |
124 | expecting the MS standard format may become confused; @file{PEview} is | |
125 | one known example. | |
126 | ||
68ffbac6 | 127 | The functionality is supported in BFD by code implemented under |
88183869 DK |
128 | the control of the macro @code{COFF_LONG_SECTION_NAMES}. If not |
129 | defined, the format does not support long section names in any way. | |
68ffbac6 L |
130 | If defined, it is used to initialise a flag, |
131 | @code{_bfd_coff_long_section_names}, and a hook function pointer, | |
88183869 DK |
132 | @code{_bfd_coff_set_long_section_names}, in the Coff backend data |
133 | structure. The flag controls the generation of long section names | |
134 | in output BFDs at runtime; if it is false, as it will be by default | |
135 | when generating an executable image, long section names are truncated; | |
136 | if true, the long section names extension is employed. The hook | |
137 | points to a function that allows the value of the flag to be altered | |
138 | at runtime, on formats that support long section names at all; on | |
139 | other formats it points to a stub that returns an error indication. | |
68ffbac6 | 140 | |
0408dee6 DK |
141 | With input BFDs, the flag is set according to whether any long section |
142 | names are detected while reading the section headers. For a completely | |
143 | new BFD, the flag is set to the default for the target format. This | |
144 | information can be used by a client of the BFD library when deciding | |
145 | what output format to generate, and means that a BFD that is opened | |
146 | for read and subsequently converted to a writeable BFD and modified | |
147 | in-place will retain whatever format it had on input. | |
88183869 DK |
148 | |
149 | If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is | |
150 | defined to the value "1", then long section names are enabled by | |
151 | default; if it is defined to the value zero, they are disabled by | |
152 | default (but still accepted in input BFDs). The header @file{coffcode.h} | |
153 | defines a macro, @code{COFF_DEFAULT_LONG_SECTION_NAMES}, which is | |
154 | used in the backends to initialise the backend data structure fields | |
155 | appropriately; see the comments for further detail. | |

157 | SUBSUBSECTION |
158 | Bit twiddling | |
159 | ||
160 | Each flavour of coff supported in BFD has its own header file | |
161 | describing the external layout of the structures. There is also | |
162 | an internal description of the coff layout, in | |
163 | @file{coff/internal.h}. A major function of the | |
164 | coff backend is swapping the bytes and twiddling the bits to | |
165 | translate the external form of the structures into the normal | |
166 | internal form. This is all performed in the | |
167 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some | |
168 | elements are different sizes between different versions of | |
169 | coff; it is the duty of the coff version specific include file | |
170 | to override the definitions of various packing routines in | |
171 | @file{coffcode.h}. E.g., the size of line number entry in coff is | |
172 | sometimes 16 bits, and sometimes 32 bits. @code{#define}ing | |
173 | @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the | |
174 | correct one. No doubt, some day someone will find a version of | |
175 | coff which has a varying field size not catered to at the | |
176 | moment. To port BFD, that person will have to add more @code{#defines}. | |
177 | Three of the bit twiddling routines are exported to | |
178 | @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} | |
00692651 | 179 | and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol |
252b5132 RH |
180 | table on its own, but uses BFD to fix things up. More of the |
181 | bit twiddlers are exported for @code{gas}; | |
182 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, | |
183 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, | |
184 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, | |
185 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track | |
186 | of all the symbol table and reloc drudgery itself, thereby | |
187 | saving the internal BFD overhead, but uses BFD to swap things | |
188 | on the way out, making cross ports much safer. Doing so also | |
189 | allows BFD (and thus the linker) to use the same header files | |
190 | as @code{gas}, which makes one avenue to disaster disappear. | |
191 | ||
192 | SUBSUBSECTION | |
193 | Symbol reading | |
194 | ||
195 | The simple canonical form for symbols used by BFD is not rich | |
196 | enough to keep all the information available in a coff symbol | |
197 | table. The back end gets around this problem by keeping the original | |
198 | symbol table around, "behind the scenes". | |
199 | ||
200 | When a symbol table is requested (through a call to | |
201 | @code{bfd_canonicalize_symtab}), a request gets through to | |
202 | @code{coff_get_normalized_symtab}. This reads the symbol table from | |
203 | the coff file and swaps all the structures inside into the | |
204 | internal form. It also fixes up all the pointers in the table | |
205 | (represented in the file by offsets from the first symbol in | |
206 | the table) into physical pointers to elements in the new | |
207 | internal table. This involves some work since the meanings of | |
208 | fields change depending upon context: a field that is a | |
209 | pointer to another structure in the symbol table at one moment | |
210 | may be the size in bytes of a structure at the next. Another | |
211 | pass is made over the table. All symbols which mark file names | |
212 | (<<C_FILE>> symbols) are modified so that the internal | |
213 | string points to the value in the auxent (the real filename) | |
214 | rather than the normal text associated with the symbol | |
215 | (@code{".file"}). | |
216 | ||
217 | At this time the symbol names are moved around. Coff stores | |
218 | all symbols less than nine characters long physically | |
219 | within the symbol table; longer strings are kept at the end of | |
46f2f11d | 220 | the file in the string table. This pass moves all strings |
252b5132 RH |
221 | into memory and replaces them with pointers to the strings. |
222 | ||
252b5132 RH |
223 | The symbol table is massaged once again, this time to create |
224 | the canonical table used by the BFD application. Each symbol | |
225 | is inspected in turn, and a decision made (using the | |
226 | @code{sclass} field) about the various flags to set in the | |
227 | @code{asymbol}. @xref{Symbols}. The generated canonical table | |
228 | shares strings with the hidden internal symbol table. | |
229 | ||
230 | Any linenumbers are read from the coff file too, and attached | |
231 | to the symbols which own the functions the linenumbers belong to. | |
232 | ||
233 | SUBSUBSECTION | |
234 | Symbol writing | |
235 | ||
236 | Writing a symbol to a coff file which didn't come from a coff | |
237 | file will lose any debugging information. The @code{asymbol} | |
238 | structure remembers the BFD from which the symbol was taken, and on | |
239 | output the back end makes sure that the same destination target as | |
240 | source target is present. | |
241 | ||
242 | When the symbols have come from a coff file then all the | |
243 | debugging information is preserved. | |
244 | ||
245 | Symbol tables are provided for writing to the back end in a | |
246 | vector of pointers to pointers. This allows applications like | |
247 | the linker to accumulate and output large symbol tables | |
248 | without having to do too much byte copying. | |
249 | ||
250 | This function runs through the provided symbol table and | |
251 | patches each symbol marked as a file place holder | |
252 | (@code{C_FILE}) to point to the next file place holder in the | |
253 | list. It also marks each @code{offset} field in the list with | |
254 | the offset from the first symbol of the current symbol. | |
255 | ||
256 | Another function of this procedure is to turn the canonical | |
257 | value form of BFD into the form used by coff. Internally, BFD | |
258 | expects symbol values to be offsets from a section base; so a | |
259 | symbol physically at 0x120, but in a section starting at | |
260 | 0x100, would have the value 0x20. Coff expects symbols to | |
261 | contain their final value, so symbols have their values | |
262 | changed at this point to reflect their sum with their owning | |
263 | section. This transformation uses the | |
264 | <<output_section>> field of the @code{asymbol}'s | |
265 | @code{asection} @xref{Sections}. | |
266 | ||
267 | o <<coff_mangle_symbols>> | |
268 | ||
269 | This routine runs though the provided symbol table and uses | |
270 | the offsets generated by the previous pass and the pointers | |
271 | generated when the symbol table was read in to create the | |
ed781d5d | 272 | structured hierarchy required by coff. It changes each pointer |
252b5132 RH |
273 | to a symbol into the index into the symbol table of the asymbol. |
274 | ||
275 | o <<coff_write_symbols>> | |
276 | ||
277 | This routine runs through the symbol table and patches up the | |
278 | symbols from their internal form into the coff way, calls the | |
279 | bit twiddlers, and writes out the table to the file. | |

5069 | Coff relocations are easily transformed into the internal BFD form | |
5070 | (@code{arelent}). | |
5071 | ||
5072 | Reading a coff relocation table is done in the following stages: | |
5073 | ||
5074 | o Read the entire coff relocation table into memory. | |
5075 | ||
5076 | o Process each relocation in turn; first swap it from the | |
5077 | external to the internal form. | |
5078 | ||
5079 | o Turn the symbol referenced in the relocation's symbol index | |
5080 | into a pointer into the canonical symbol table. | |
5081 | This table is the same as the one returned by a call to | |
5082 | @code{bfd_canonicalize_symtab}. The back end will call that | |
5083 | routine and save the result if a canonicalization hasn't been done. | |
5084 | ||
5085 | o The reloc index is turned into a pointer to a howto | |
5086 | structure, in a back end specific way. For instance, the 386 | |
a8eb42a8 | 5087 | uses the @code{r_type} to directly produce an index |
c2bf1eec | 5088 | into a howto table vector. |
