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} |
135 | and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol |
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 | |
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 |
228 | structured hierarchy 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. |

4991 | Coff relocations are easily transformed into the internal BFD form |
4992 | (@code{arelent}). |
4993 | |
4994 | Reading a coff relocation table is done in the following stages: |
4995 | |
4996 | o Read the entire coff relocation table into memory. |
4997 | |
4998 | o Process each relocation in turn; first swap it from the |
4999 | external to the internal form. |
5000 | |
5001 | o Turn the symbol referenced in the relocation's symbol index |
5002 | into a pointer into the canonical symbol table. |
5003 | This table is the same as the one returned by a call to |
5004 | @code{bfd_canonicalize_symtab}. The back end will call that |
5005 | routine and save the result if a canonicalization hasn't been done. |
5006 | |
5007 | o The reloc index is turned into a pointer to a howto |
5008 | structure, in a back end specific way. For instance, the 386 |
5009 | and 960 use the @code{r_type} to directly produce an index |
5010 | into a howto table vector; the 88k subtracts a number from the |
5011 | @code{r_type} field and creates an addend field. |
