29 | SECTION | |
30 | coff backends | |
31 | ||
32 | BFD supports a number of different flavours of coff format. | |
33 | The major differences between formats are the sizes and | |
34 | alignments of fields in structures on disk, and the occasional | |
35 | extra field. | |
36 | ||
37 | Coff in all its varieties is implemented with a few common | |
38 | files and a number of implementation specific files. For | |
39 | example, The 88k bcs coff format is implemented in the file | |
40 | @file{coff-m88k.c}. This file @code{#include}s | |
41 | @file{coff/m88k.h} which defines the external structure of the | |
42 | coff format for the 88k, and @file{coff/internal.h} which | |
43 | defines the internal structure. @file{coff-m88k.c} also | |
44 | defines the relocations used by the 88k format | |
45 | @xref{Relocations}. | |
46 | ||
47 | The Intel i960 processor version of coff is implemented in | |
48 | @file{coff-i960.c}. This file has the same structure as | |
49 | @file{coff-m88k.c}, except that it includes @file{coff/i960.h} | |
50 | rather than @file{coff-m88k.h}. | |
51 | ||
52 | SUBSECTION | |
53 | Porting to a new version of coff | |
54 | ||
55 | The recommended method is to select from the existing | |
56 | implementations the version of coff which is most like the one | |
57 | you want to use. For example, we'll say that i386 coff is | |
58 | the one you select, and that your coff flavour is called foo. | |
59 | Copy @file{i386coff.c} to @file{foocoff.c}, copy | |
60 | @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, | |
61 | and add the lines to @file{targets.c} and @file{Makefile.in} | |
62 | so that your new back end is used. Alter the shapes of the | |
63 | structures in @file{../include/coff/foo.h} so that they match | |
64 | what you need. You will probably also have to add | |
65 | @code{#ifdef}s to the code in @file{coff/internal.h} and | |
66 | @file{coffcode.h} if your version of coff is too wild. | |
67 | ||
68 | You can verify that your new BFD backend works quite simply by | |
69 | building @file{objdump} from the @file{binutils} directory, | |
70 | and making sure that its version of what's going on and your | |
71 | host system's idea (assuming it has the pretty standard coff | |
72 | dump utility, usually called @code{att-dump} or just | |
73 | @code{dump}) are the same. Then clean up your code, and send | |
74 | what you've done to Cygnus. Then your stuff will be in the | |
75 | next release, and you won't have to keep integrating it. | |
76 | ||
77 | SUBSECTION | |
78 | How the coff backend works | |
79 | ||
80 | SUBSUBSECTION | |
81 | File layout | |
82 | ||
83 | The Coff backend is split into generic routines that are | |
84 | applicable to any Coff target and routines that are specific | |
85 | to a particular target. The target-specific routines are | |
86 | further split into ones which are basically the same for all | |
87 | Coff targets except that they use the external symbol format | |
88 | or use different values for certain constants. | |
89 | ||
90 | The generic routines are in @file{coffgen.c}. These routines | |
91 | work for any Coff target. They use some hooks into the target | |
92 | specific code; the hooks are in a @code{bfd_coff_backend_data} | |
93 | structure, one of which exists for each target. | |
94 | ||
95 | The essentially similar target-specific routines are in | |
96 | @file{coffcode.h}. This header file includes executable C code. | |
97 | The various Coff targets first include the appropriate Coff | |
98 | header file, make any special defines that are needed, and | |
99 | then include @file{coffcode.h}. | |
100 | ||
101 | Some of the Coff targets then also have additional routines in | |
102 | the target source file itself. | |
103 | ||
104 | For example, @file{coff-i960.c} includes | |
105 | @file{coff/internal.h} and @file{coff/i960.h}. It then | |
106 | defines a few constants, such as @code{I960}, and includes | |
107 | @file{coffcode.h}. Since the i960 has complex relocation | |
108 | types, @file{coff-i960.c} also includes some code to | |
109 | manipulate the i960 relocs. This code is not in | |
110 | @file{coffcode.h} because it would not be used by any other | |
111 | target. | |
112 | ||
113 | SUBSUBSECTION | |
114 | Bit twiddling | |
115 | ||
116 | Each flavour of coff supported in BFD has its own header file | |
117 | describing the external layout of the structures. There is also | |
118 | an internal description of the coff layout, in | |
119 | @file{coff/internal.h}. A major function of the | |
120 | coff backend is swapping the bytes and twiddling the bits to | |
121 | translate the external form of the structures into the normal | |
122 | internal form. This is all performed in the | |
123 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some | |
124 | elements are different sizes between different versions of | |
125 | coff; it is the duty of the coff version specific include file | |
126 | to override the definitions of various packing routines in | |
127 | @file{coffcode.h}. E.g., the size of line number entry in coff is | |
128 | sometimes 16 bits, and sometimes 32 bits. @code{#define}ing | |
129 | @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the | |
130 | correct one. No doubt, some day someone will find a version of | |
131 | coff which has a varying field size not catered to at the | |
132 | moment. To port BFD, that person will have to add more @code{#defines}. | |
133 | Three of the bit twiddling routines are exported to | |
134 | @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} | |
00692651 | 135 | and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol |
252b5132 RH |
136 | table on its own, but uses BFD to fix things up. More of the |
137 | bit twiddlers are exported for @code{gas}; | |
138 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, | |
139 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, | |
140 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, | |
141 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track | |
142 | of all the symbol table and reloc drudgery itself, thereby | |
143 | saving the internal BFD overhead, but uses BFD to swap things | |
144 | on the way out, making cross ports much safer. Doing so also | |
145 | allows BFD (and thus the linker) to use the same header files | |
146 | as @code{gas}, which makes one avenue to disaster disappear. | |
147 | ||
148 | SUBSUBSECTION | |
149 | Symbol reading | |
150 | ||
151 | The simple canonical form for symbols used by BFD is not rich | |
152 | enough to keep all the information available in a coff symbol | |
153 | table. The back end gets around this problem by keeping the original | |
154 | symbol table around, "behind the scenes". | |
155 | ||
156 | When a symbol table is requested (through a call to | |
157 | @code{bfd_canonicalize_symtab}), a request gets through to | |
158 | @code{coff_get_normalized_symtab}. This reads the symbol table from | |
159 | the coff file and swaps all the structures inside into the | |
160 | internal form. It also fixes up all the pointers in the table | |
161 | (represented in the file by offsets from the first symbol in | |
162 | the table) into physical pointers to elements in the new | |
163 | internal table. This involves some work since the meanings of | |
164 | fields change depending upon context: a field that is a | |
165 | pointer to another structure in the symbol table at one moment | |
166 | may be the size in bytes of a structure at the next. Another | |
167 | pass is made over the table. All symbols which mark file names | |
168 | (<<C_FILE>> symbols) are modified so that the internal | |
169 | string points to the value in the auxent (the real filename) | |
170 | rather than the normal text associated with the symbol | |
171 | (@code{".file"}). | |
172 | ||
173 | At this time the symbol names are moved around. Coff stores | |
174 | all symbols less than nine characters long physically | |
175 | within the symbol table; longer strings are kept at the end of | |
176 | the file in the string table. This pass moves all strings | |
177 | into memory and replaces them with pointers to the strings. | |
178 | ||
252b5132 RH |
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. | |
188 | ||
189 | SUBSUBSECTION | |
190 | 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 | |
ed781d5d | 228 | structured hierarchy required by coff. It changes each pointer |
252b5132 RH |
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. | |

4271 | with the number. | |

4273 | I have found no documentation on the contents of this section. | |
4274 | Experimentation indicates that the section contains zero or more | |
4275 | records, each of which has the following structure: | |
4276 | ||
4277 | - a (four byte) word holding the length of this record, in words, | |
4278 | - a word that always seems to be set to "2", | |
4279 | - the path to a shared library, null-terminated and then padded | |
4280 | to a whole word boundary. | |
4281 | ||
4282 | bfd_assert calls have been added to alert if an attempt is made | |
4283 | to write a section which doesn't follow these assumptions. The | |
4284 | code has been tested on ISC 4.1 by me, and on SCO by Robert Lipe | |

4913 | Reading relocations | |

4915 | Coff relocations are easily transformed into the internal BFD form | |
4916 | (@code{arelent}). | |
4917 | ||
4918 | Reading a coff relocation table is done in the following stages: | |
4919 | ||
4920 | o Read the entire coff relocation table into memory. | |
4921 | ||
4922 | o Process each relocation in turn; first swap it from the | |
4923 | external to the internal form. | |
4924 | ||
4925 | o Turn the symbol referenced in the relocation's symbol index | |
4926 | into a pointer into the canonical symbol table. | |
4927 | This table is the same as the one returned by a call to | |
4928 | @code{bfd_canonicalize_symtab}. The back end will call that | |
4929 | routine and save the result if a canonicalization hasn't been done. | |
4930 | ||
4931 | o The reloc index is turned into a pointer to a howto | |
4932 | structure, in a back end specific way. For instance, the 386 | |
4933 | and 960 use the @code{r_type} to directly produce an index | |
4934 | into a howto table vector; the 88k subtracts a number from the | |
4935 | @code{r_type} field and creates an addend field. | |
