22 | @section coff backends | |
23 | ||
24 | BFD supports a number of different flavours of coff format. The major | |
25 | difference between formats are the sizes and alignments of fields in | |
26 | structures on disk, and the occasional extra field. | |
27 | ||
28 | Coff in all its varieties is implimented with a few common files and a | |
29 | number of implementation specific files. For example, The 88k bcs coff | |
30 | format is implemented in the file @code{m88k-bcs.c}. This file | |
31 | @code{#include}s @code{m88k-bcs.h} which defines the external | |
32 | structure of the coff format for the 88k, and @code{internalcoff.h} | |
33 | which defines the internal structure. @code{m88k-bcs.c} also defines | |
34 | the relocations used by the 88k format @xref{Relocations}. Then the | |
35 | major portion of coff code is included (@code{coffcode.h}) which | |
36 | defines the methods used to act upon the types defined in | |
cbdc7909 | 37 | @code{m88k-bcs.h} and @code{internalcoff.h}. |
6f715d66 SC |
38 | |
39 | The Intel i960 processor version of coff is implemented in | |
cbdc7909 | 40 | @code{icoff.c}. This file has the same structure as |
6f715d66 | 41 | @code{m88k-bcs.c}, except that it includes @code{intel-coff.h} rather |
cbdc7909 | 42 | than @code{m88k-bcs.h}. |
6f715d66 SC |
43 | |
44 | @subsection Porting To A New Version of Coff | |
45 | ||
46 | The recommended method is to select from the existing implimentations | |
47 | the version of coff which is most like the one you want to use, for | |
48 | our purposes, we'll say that i386 coff is the one you select, and that | |
49 | your coff flavour is called foo. Copy the @code{i386coff.c} to @code{foocoff.c}, | |
50 | copy @code{../include/i386coff.h} to @code{../include/foocoff.h} and | |
51 | add the lines to @code{targets.c} and @code{Makefile.in} so that your | |
cbdc7909 | 52 | new back end is used. |
6f715d66 SC |
53 | |
54 | Alter the shapes of the structures in @code{../include/foocoff.h} so | |
55 | that they match what you need. You will probably also have to add | |
56 | @code{#ifdef}s to the code in @code{internalcoff.h} and | |
57 | @code{coffcode.h} if your version of coff is too wild. | |
58 | ||
6724ff46 | 59 | You can verify that your new BFD backend works quite simply by |
6f715d66 SC |
60 | building @code{objdump} from the @code{binutils} directory, and |
61 | making sure that its version of what's going on at your host systems | |
62 | idea (assuming it has the pretty standard coff dump utility (usually | |
63 | called @code{att-dump} or just @code{dump})) are the same. | |
64 | ||
65 | Then clean up your code, and send what you've done to Cygnus. Then your stuff | |
66 | will be in the next release, and you won't have to keep integrating | |
67 | it. | |
68 | ||
69 | @subsection How The Coff Backend Works | |
70 | ||
71 | @subsubsection Bit Twiddling | |
6724ff46 | 72 | Each flavour of coff supported in BFD has its own header file |
6f715d66 SC |
73 | descibing the external layout of the structures. There is also an |
74 | internal description of the coff layout (in @code{internalcoff.h}) | |
75 | file (@code{}). A major function of the coff backend is swapping the | |
76 | bytes and twiddling the bits to translate the external form of the | |
77 | structures into the normal internal form. This is all performed in the | |
78 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some elements are | |
79 | different sizes between different versions of coff, it is the duty of | |
80 | the coff version specific include file to override the definitions of | |
81 | various packing routines in @code{coffcode.h}. Eg the size of line | |
82 | number entry in coff is sometimes 16 bits, and sometimes 32 bits. | |
83 | @code{#define}ing @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will | |
84 | select the correct one. No doubt, some day someone will find a version | |
85 | of coff which has a varying field size not catered for at the moment. | |
6724ff46 | 86 | To port BFD, that person will have to add more @code{#defines}. |
6f715d66 SC |
87 | |
88 | Three of the bit twiddling routines are exported to @code{gdb}; | |
89 | @code{coff_swap_aux_in}, @code{coff_swap_sym_in} and | |
90 | @code{coff_swap_linno_in}. @code{GDB} reads the symbol table on its | |
6724ff46 | 91 | own, but uses BFD to fix things up. |
6f715d66 | 92 | |
0d740984 SC |
93 | More of the bit twiddlers are exported for @code{gas}; |
94 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, | |
95 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, | |
96 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, | |
97 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track of all | |
98 | the symbol table and reloc drudgery itself, thereby saving the | |
99 | internal BFD overhead, but uses BFD to swap things on the way out, | |
100 | making cross ports much safer. This also allows BFD (and thus the | |
101 | linker) to use the same header files as @code{gas}, which makes one | |
102 | avenue to disaster disappear. | |
103 | ||
6f715d66 | 104 | @subsubsection Symbol Reading |
6724ff46 | 105 | The simple canonical form for symbols used by BFD is not rich enough |
6f715d66 SC |
106 | to keep all the information available in a coff symbol table. The back |
107 | end gets around this by keeping the original symbol table around, | |
cbdc7909 | 108 | "behind the scenes". |
6f715d66 SC |
109 | |
110 | When a symbol table is requested (through a call to | |
111 | @code{bfd_canonicalize_symtab}, a request gets through to | |
112 | @code{get_normalized_symtab}. This reads the symbol table from the | |
113 | coff file and swaps all the structures inside into the internal form. | |
114 | It also fixes up all the pointers in the table (represented in the file | |
115 | by offsets from the first symbol in the table) into physical pointers | |
116 | to elements in the new internal table. This involves some work since | |
117 | the meanings of fields changes depending upon context; a field that is a | |
118 | pointer to another structure in the symbol table at one moment may be | |
119 | the size in bytes of a structure in the next. | |
120 | ||
121 | Another pass is made over the table. All symbols which mark file names | |
122 | (@code{C_FILE} symbols) are modified so that the internal string | |
123 | points to the value in the auxent (the real filename) rather than the | |
124 | normal text associated with the symbol (@code{".file"}). | |
125 | ||
126 | At this time the symbol names are moved around. Coff stores all | |
127 | symbols less than nine characters long physically within the symbol | |
128 | table, longer strings are kept at the end of the file in the string | |
129 | table. This pass moves all strings into memory, and replaces them with | |
130 | pointers to the strings. | |
131 | ||
132 | The symbol table is massaged once again, this time to create the | |
6724ff46 | 133 | canonical table used by the BFD application. Each symbol is inspected |
6f715d66 SC |
134 | in turn, and a decision made (using the @code{sclass} field) about the |
135 | various flags to set in the @code{asymbol} @xref{Symbols}. The | |
136 | generated canonical table shares strings with the hidden internal | |
137 | symbol table. | |
138 | ||
7d003262 | 139 | Any linenumbers are read from the coff file too, and attached to the |
6f715d66 SC |
140 | symbols which own the functions the linenumbers belong to. |
141 | ||
142 | @subsubsection Symbol Writing | |
143 | Writing a symbol to a coff file which didn't come from a coff file | |
144 | will lose any debugging information. The @code{asymbol} structure | |
6724ff46 | 145 | remembers the BFD from which was born, and on output the back end |
6f715d66 SC |
146 | makes sure that the same destination target as source target is |
147 | present. | |
148 | ||
149 | When the symbols have come from a coff file then all the debugging | |
cbdc7909 | 150 | information is preserved. |
6f715d66 SC |
151 | |
152 | Symbol tables are provided for writing to the back end in a vector of | |
153 | pointers to pointers. This allows applications like the linker to | |
154 | accumulate and output large symbol tables without having to do too | |
155 | much byte copying. | |
156 | ||
cbdc7909 | 157 | The symbol table is not output to a writable BFD until it is closed. |
6f715d66 SC |
158 | The order of operations on the canonical symbol table at that point |
159 | are: | |
160 | @table @code | |
161 | @item coff_renumber_symbols | |
162 | This function runs through the provided symbol table and patches each | |
163 | symbol marked as a file place holder (@code{C_FILE}) to point to the | |
164 | next file place holder in the list. It also marks each @code{offset} | |
165 | field in the list with the offset from the first symbol of the current | |
cbdc7909 | 166 | symbol. |
6f715d66 SC |
167 | |
168 | Another function of this procedure is to turn the canonical value form | |
6724ff46 | 169 | of BFD into the form used by coff. Internally, BFD expects symbol |
6f715d66 SC |
170 | values to be offsets from a section base; so a symbol physically at |
171 | 0x120, but in a section starting at 0x100, would have the value 0x20. | |
172 | Coff expects symbols to contain their final value, so symbols have | |
173 | their values changed at this point to reflect their sum with their | |
174 | owning section. Note that this transformation uses the | |
175 | @code{output_section} field of the @code{asymbol}'s @code{asection} | |
176 | @xref{Sections}. | |
177 | @item coff_mangle_symbols | |
178 | This routine runs though the provided symbol table and uses the | |
179 | offsets generated by the previous pass and the pointers generated when | |
180 | the symbol table was read in to create the structured hierachy | |
181 | required by coff. It changes each pointer to a symbol to an index into | |
182 | the symbol table of the symbol being referenced. | |
183 | @item coff_write_symbols | |
184 | This routine runs through the symbol table and patches up the symbols | |
185 | from their internal form into the coff way, calls the bit twiddlers | |
186 | and writes out the tabel to the file. | |
187 | @end table | |

3104 | @subsubsection Reading Relocations | |
6724ff46 | 3105 | Coff relocations are easily transformed into the internal BFD form |
cbdc7909 | 3106 | (@code{arelent}). |
6f715d66 SC |
3107 | |
3108 | Reading a coff relocation table is done in the following stages: | |
3109 | @itemize @bullet | |
cbdc7909 | 3110 | @item |
6f715d66 SC |
3111 | The entire coff relocation table is read into memory. |
3112 | @item | |
3113 | Each relocation is processed in turn, first it is swapped from the | |
3114 | external to the internal form. | |
3115 | @item | |
3116 | The symbol referenced in the relocation's symbol index is turned into | |
3117 | a pointer into the canonical symbol table. Note that this table is the | |
3118 | same as the one returned by a call to @code{bfd_canonicalize_symtab}. | |
3119 | The back end will call the routine and save the result if a | |
3120 | canonicalization hasn't been done. | |
3121 | @item | |
3122 | The reloc index is turned into a pointer to a howto structure, in a | |
3123 | back end specific way. For instance, the 386 and 960 use the | |
3124 | @code{r_type} to directly produce an index into a howto table vector; | |
3125 | the 88k subtracts a number from the @code{r_type} field and creates an | |
3126 | addend field. | |
