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 | |
35 | example, The 88k bcs coff format is implemented in the file | |
36 | @file{coff-m88k.c}. This file @code{#include}s | |
37 | @file{coff/m88k.h} which defines the external structure of the | |
38 | coff format for the 88k, and @file{coff/internal.h} which | |
39 | defines the internal structure. @file{coff-m88k.c} also | |
40 | defines the relocations used by the 88k format | |
41 | @xref{Relocations}. | |
42 | ||
43 | The Intel i960 processor version of coff is implemented in | |
44 | @file{coff-i960.c}. This file has the same structure as | |
45 | @file{coff-m88k.c}, except that it includes @file{coff/i960.h} | |
46 | rather than @file{coff-m88k.h}. | |
47 | ||
48 | SUBSECTION | |
49 | Porting to a new version of coff | |
50 | ||
51 | The recommended method is to select from the existing | |
52 | implementations the version of coff which is most like the one | |
53 | you want to use. For example, we'll say that i386 coff is | |
54 | the one you select, and that your coff flavour is called foo. | |
55 | Copy @file{i386coff.c} to @file{foocoff.c}, copy | |
56 | @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, | |
57 | and add the lines to @file{targets.c} and @file{Makefile.in} | |
58 | so that your new back end is used. Alter the shapes of the | |
59 | structures in @file{../include/coff/foo.h} so that they match | |
60 | what you need. You will probably also have to add | |
61 | @code{#ifdef}s to the code in @file{coff/internal.h} and | |
62 | @file{coffcode.h} if your version of coff is too wild. | |
63 | ||
64 | You can verify that your new BFD backend works quite simply by | |
65 | building @file{objdump} from the @file{binutils} directory, | |
66 | and making sure that its version of what's going on and your | |
67 | host system's idea (assuming it has the pretty standard coff | |
68 | dump utility, usually called @code{att-dump} or just | |
69 | @code{dump}) are the same. Then clean up your code, and send | |
70 | what you've done to Cygnus. Then your stuff will be in the | |
71 | next release, and you won't have to keep integrating it. | |
72 | ||
73 | SUBSECTION | |
74 | How the coff backend works | |
75 | ||
76 | SUBSUBSECTION | |
77 | File layout | |
78 | ||
79 | The Coff backend is split into generic routines that are | |
80 | applicable to any Coff target and routines that are specific | |
81 | to a particular target. The target-specific routines are | |
82 | further split into ones which are basically the same for all | |
83 | Coff targets except that they use the external symbol format | |
84 | or use different values for certain constants. | |
85 | ||
86 | The generic routines are in @file{coffgen.c}. These routines | |
87 | work for any Coff target. They use some hooks into the target | |
88 | specific code; the hooks are in a @code{bfd_coff_backend_data} | |
89 | structure, one of which exists for each target. | |
90 | ||
91 | The essentially similar target-specific routines are in | |
92 | @file{coffcode.h}. This header file includes executable C code. | |
93 | The various Coff targets first include the appropriate Coff | |
94 | header file, make any special defines that are needed, and | |
95 | then include @file{coffcode.h}. | |
96 | ||
97 | Some of the Coff targets then also have additional routines in | |
98 | the target source file itself. | |
99 | ||
100 | For example, @file{coff-i960.c} includes | |
101 | @file{coff/internal.h} and @file{coff/i960.h}. It then | |
102 | defines a few constants, such as @code{I960}, and includes | |
103 | @file{coffcode.h}. Since the i960 has complex relocation | |
104 | types, @file{coff-i960.c} also includes some code to | |
105 | manipulate the i960 relocs. This code is not in | |
106 | @file{coffcode.h} because it would not be used by any other | |
107 | target. | |

109 | SUBSUBSECTION |
110 | Coff long section names | |
111 | ||
112 | In the standard Coff object format, section names are limited to | |
113 | the eight bytes available in the @code{s_name} field of the | |
114 | @code{SCNHDR} section header structure. The format requires the | |
115 | field to be NUL-padded, but not necessarily NUL-terminated, so | |
116 | the longest section names permitted are a full eight characters. | |
117 | ||
118 | The Microsoft PE variants of the Coff object file format add | |
119 | an extension to support the use of long section names. This | |
68ffbac6 | 120 | extension is defined in section 4 of the Microsoft PE/COFF |
88183869 DK |
121 | specification (rev 8.1). If a section name is too long to fit |
122 | into the section header's @code{s_name} field, it is instead | |
123 | placed into the string table, and the @code{s_name} field is | |
68ffbac6 | 124 | filled with a slash ("/") followed by the ASCII decimal |
88183869 DK |
125 | representation of the offset of the full name relative to the |
126 | string table base. | |
127 | ||
128 | Note that this implies that the extension can only be used in object | |
129 | files, as executables do not contain a string table. The standard | |
130 | specifies that long section names from objects emitted into executable | |
131 | images are to be truncated. | |
132 | ||
133 | However, as a GNU extension, BFD can generate executable images | |
134 | that contain a string table and long section names. This | |
135 | would appear to be technically valid, as the standard only says | |
136 | that Coff debugging information is deprecated, not forbidden, | |
137 | and in practice it works, although some tools that parse PE files | |
138 | expecting the MS standard format may become confused; @file{PEview} is | |
139 | one known example. | |
140 | ||
68ffbac6 | 141 | The functionality is supported in BFD by code implemented under |
88183869 DK |
142 | the control of the macro @code{COFF_LONG_SECTION_NAMES}. If not |
143 | defined, the format does not support long section names in any way. | |
68ffbac6 L |
144 | If defined, it is used to initialise a flag, |
145 | @code{_bfd_coff_long_section_names}, and a hook function pointer, | |
88183869 DK |
146 | @code{_bfd_coff_set_long_section_names}, in the Coff backend data |
147 | structure. The flag controls the generation of long section names | |
148 | in output BFDs at runtime; if it is false, as it will be by default | |
149 | when generating an executable image, long section names are truncated; | |
150 | if true, the long section names extension is employed. The hook | |
151 | points to a function that allows the value of the flag to be altered | |
152 | at runtime, on formats that support long section names at all; on | |
153 | other formats it points to a stub that returns an error indication. | |
68ffbac6 | 154 | |
0408dee6 DK |
155 | With input BFDs, the flag is set according to whether any long section |
156 | names are detected while reading the section headers. For a completely | |
157 | new BFD, the flag is set to the default for the target format. This | |
158 | information can be used by a client of the BFD library when deciding | |
159 | what output format to generate, and means that a BFD that is opened | |
160 | for read and subsequently converted to a writeable BFD and modified | |
161 | in-place will retain whatever format it had on input. | |
88183869 DK |
162 | |
163 | If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is | |
164 | defined to the value "1", then long section names are enabled by | |
165 | default; if it is defined to the value zero, they are disabled by | |
166 | default (but still accepted in input BFDs). The header @file{coffcode.h} | |
167 | defines a macro, @code{COFF_DEFAULT_LONG_SECTION_NAMES}, which is | |
168 | used in the backends to initialise the backend data structure fields | |
169 | appropriately; see the comments for further detail. | |

171 | SUBSUBSECTION |
172 | Bit twiddling | |
173 | ||
174 | Each flavour of coff supported in BFD has its own header file | |
175 | describing the external layout of the structures. There is also | |
176 | an internal description of the coff layout, in | |
177 | @file{coff/internal.h}. A major function of the | |
178 | coff backend is swapping the bytes and twiddling the bits to | |
179 | translate the external form of the structures into the normal | |
180 | internal form. This is all performed in the | |
181 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some | |
182 | elements are different sizes between different versions of | |
183 | coff; it is the duty of the coff version specific include file | |
184 | to override the definitions of various packing routines in | |
185 | @file{coffcode.h}. E.g., the size of line number entry in coff is | |
186 | sometimes 16 bits, and sometimes 32 bits. @code{#define}ing | |
187 | @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the | |
188 | correct one. No doubt, some day someone will find a version of | |
189 | coff which has a varying field size not catered to at the | |
190 | moment. To port BFD, that person will have to add more @code{#defines}. | |
191 | Three of the bit twiddling routines are exported to | |
192 | @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} | |
00692651 | 193 | and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol |
252b5132 RH |
194 | table on its own, but uses BFD to fix things up. More of the |
195 | bit twiddlers are exported for @code{gas}; | |
196 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, | |
197 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, | |
198 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, | |
199 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track | |
200 | of all the symbol table and reloc drudgery itself, thereby | |
201 | saving the internal BFD overhead, but uses BFD to swap things | |
202 | on the way out, making cross ports much safer. Doing so also | |
203 | allows BFD (and thus the linker) to use the same header files | |
204 | as @code{gas}, which makes one avenue to disaster disappear. | |
205 | ||
206 | SUBSUBSECTION | |
207 | Symbol reading | |
208 | ||
209 | The simple canonical form for symbols used by BFD is not rich | |
210 | enough to keep all the information available in a coff symbol | |
211 | table. The back end gets around this problem by keeping the original | |
212 | symbol table around, "behind the scenes". | |
213 | ||
214 | When a symbol table is requested (through a call to | |
215 | @code{bfd_canonicalize_symtab}), a request gets through to | |
216 | @code{coff_get_normalized_symtab}. This reads the symbol table from | |
217 | the coff file and swaps all the structures inside into the | |
218 | internal form. It also fixes up all the pointers in the table | |
219 | (represented in the file by offsets from the first symbol in | |
220 | the table) into physical pointers to elements in the new | |
221 | internal table. This involves some work since the meanings of | |
222 | fields change depending upon context: a field that is a | |
223 | pointer to another structure in the symbol table at one moment | |
224 | may be the size in bytes of a structure at the next. Another | |
225 | pass is made over the table. All symbols which mark file names | |
226 | (<<C_FILE>> symbols) are modified so that the internal | |
227 | string points to the value in the auxent (the real filename) | |
228 | rather than the normal text associated with the symbol | |
229 | (@code{".file"}). | |
230 | ||
231 | At this time the symbol names are moved around. Coff stores | |
232 | all symbols less than nine characters long physically | |
233 | within the symbol table; longer strings are kept at the end of | |
46f2f11d | 234 | the file in the string table. This pass moves all strings |
252b5132 RH |
235 | into memory and replaces them with pointers to the strings. |
236 | ||
252b5132 RH |
237 | The symbol table is massaged once again, this time to create |
238 | the canonical table used by the BFD application. Each symbol | |
239 | is inspected in turn, and a decision made (using the | |
240 | @code{sclass} field) about the various flags to set in the | |
241 | @code{asymbol}. @xref{Symbols}. The generated canonical table | |
242 | shares strings with the hidden internal symbol table. | |
243 | ||
244 | Any linenumbers are read from the coff file too, and attached | |
245 | to the symbols which own the functions the linenumbers belong to. | |
246 | ||
247 | SUBSUBSECTION | |
248 | Symbol writing | |
249 | ||
250 | Writing a symbol to a coff file which didn't come from a coff | |
251 | file will lose any debugging information. The @code{asymbol} | |
252 | structure remembers the BFD from which the symbol was taken, and on | |
253 | output the back end makes sure that the same destination target as | |
254 | source target is present. | |
255 | ||
256 | When the symbols have come from a coff file then all the | |
257 | debugging information is preserved. | |
258 | ||
259 | Symbol tables are provided for writing to the back end in a | |
260 | vector of pointers to pointers. This allows applications like | |
261 | the linker to accumulate and output large symbol tables | |
262 | without having to do too much byte copying. | |
263 | ||
264 | This function runs through the provided symbol table and | |
265 | patches each symbol marked as a file place holder | |
266 | (@code{C_FILE}) to point to the next file place holder in the | |
267 | list. It also marks each @code{offset} field in the list with | |
268 | the offset from the first symbol of the current symbol. | |
269 | ||
270 | Another function of this procedure is to turn the canonical | |
271 | value form of BFD into the form used by coff. Internally, BFD | |
272 | expects symbol values to be offsets from a section base; so a | |
273 | symbol physically at 0x120, but in a section starting at | |
274 | 0x100, would have the value 0x20. Coff expects symbols to | |
275 | contain their final value, so symbols have their values | |
276 | changed at this point to reflect their sum with their owning | |
277 | section. This transformation uses the | |
278 | <<output_section>> field of the @code{asymbol}'s | |
279 | @code{asection} @xref{Sections}. | |
280 | ||
281 | o <<coff_mangle_symbols>> | |
282 | ||
283 | This routine runs though the provided symbol table and uses | |
284 | the offsets generated by the previous pass and the pointers | |
285 | generated when the symbol table was read in to create the | |
ed781d5d | 286 | structured hierarchy required by coff. It changes each pointer |
252b5132 RH |
287 | to a symbol into the index into the symbol table of the asymbol. |
288 | ||
289 | o <<coff_write_symbols>> | |
290 | ||
291 | This routine runs through the symbol table and patches up the | |
292 | symbols from their internal form into the coff way, calls the | |
293 | bit twiddlers, and writes out the table to the file. | |

2611 | Writing relocations | |
2612 | ||
2613 | To write relocations, the back end steps though the | |
2614 | canonical relocation table and create an | |
2615 | @code{internal_reloc}. The symbol index to use is removed from | |
2616 | the @code{offset} field in the symbol table supplied. The | |
2617 | address comes directly from the sum of the section base | |
2618 | address and the relocation offset; the type is dug directly | |
2619 | from the howto field. Then the @code{internal_reloc} is | |
2620 | swapped into the shape of an @code{external_reloc} and written | |
2621 | out to disk. | |

5115 | Coff relocations are easily transformed into the internal BFD form | |
5116 | (@code{arelent}). | |
5117 | ||
5118 | Reading a coff relocation table is done in the following stages: | |
5119 | ||
5120 | o Read the entire coff relocation table into memory. | |
5121 | ||
5122 | o Process each relocation in turn; first swap it from the | |
5123 | external to the internal form. | |
5124 | ||
5125 | o Turn the symbol referenced in the relocation's symbol index | |
5126 | into a pointer into the canonical symbol table. | |
5127 | This table is the same as the one returned by a call to | |
5128 | @code{bfd_canonicalize_symtab}. The back end will call that | |
5129 | routine and save the result if a canonicalization hasn't been done. | |
5130 | ||
5131 | o The reloc index is turned into a pointer to a howto | |
5132 | structure, in a back end specific way. For instance, the 386 | |
5133 | and 960 use the @code{r_type} to directly produce an index | |
5134 | into a howto table vector; the 88k subtracts a number from the | |
5135 | @code{r_type} field and creates an addend field. | |
