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 | ||
54 | SUBSECTION | |
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. | |
78 | ||
79 | SUBSECTION | |
80 | How The Coff Backend Works | |
81 | ||
82 | SUBSUBSECTION | |
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 | |
88 | @code{internalcoff.h}) file (@code{}). A major function of the | |
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 | ||
117 | SUBSUBSECTION | |
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 | ||
159 | SUBSUBSECTION | |
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. | |

9fda1a39 SC |
3212 | Coff relocations are easily transformed into the internal BFD form |
3213 | (@code{arelent}). | |
3214 | ||
3215 | Reading a coff relocation table is done in the following stages: | |
3216 | ||
3217 | o The entire coff relocation table is read into memory. | |
3218 | ||
3219 | o Each relocation is processed in turn, first it is swapped from the | |
3220 | external to the internal form. | |
3221 | ||
3222 | o The symbol referenced in the relocation's symbol index is | |
3223 | turned intoa pointer into the canonical symbol table. Note | |
3224 | that this table is the same as the one returned by a call to | |
3225 | @code{bfd_canonicalize_symtab}. The back end will call the | |
3226 | routine and save the result if a canonicalization hasn't been done. | |
3227 | ||
3228 | o The reloc index is turned into a pointer to a howto | |
3229 | structure, in a back end specific way. For instance, the 386 | |
3230 | and 960 use the @code{r_type} to directly produce an index | |
3231 | into a howto table vector; the 88k subtracts a number from the | |
3232 | @code{r_type} field and creates an addend field. | |
