| 27 | coff backends |
| 28 | |
| 29 | BFD supports a number of different flavours of coff format. |
| 30 | The major differences between formats are the sizes and |
| 31 | alignments of fields in structures on disk, and the occasional |
| 32 | extra field. |
| 33 | |
| 34 | Coff in all its varieties is implemented with a few common |
| 35 | files and a number of implementation specific files. For |
| 36 | example, The 88k bcs coff format is implemented in the file |
| 37 | @file{coff-m88k.c}. This file @code{#include}s |
| 38 | @file{coff/m88k.h} which defines the external structure of the |
| 39 | coff format for the 88k, and @file{coff/internal.h} which |
| 40 | defines the internal structure. @file{coff-m88k.c} also |
| 41 | defines the relocations used by the 88k format |
| 42 | @xref{Relocations}. |
| 43 | |
| 44 | The Intel i960 processor version of coff is implemented in |
| 45 | @file{coff-i960.c}. This file has the same structure as |
| 46 | @file{coff-m88k.c}, except that it includes @file{coff/i960.h} |
| 47 | rather than @file{coff-m88k.h}. |
| 48 | |
| 49 | SUBSECTION |
| 50 | Porting to a new version of coff |
| 51 | |
| 52 | The recommended method is to select from the existing |
| 53 | implementations the version of coff which is most like the one |
| 54 | you want to use. For example, we'll say that i386 coff is |
| 55 | the one you select, and that your coff flavour is called foo. |
| 56 | Copy @file{i386coff.c} to @file{foocoff.c}, copy |
| 57 | @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, |
| 58 | and add the lines to @file{targets.c} and @file{Makefile.in} |
| 59 | so that your new back end is used. Alter the shapes of the |
| 60 | structures in @file{../include/coff/foo.h} so that they match |
| 61 | what you need. You will probably also have to add |
| 62 | @code{#ifdef}s to the code in @file{coff/internal.h} and |
| 63 | @file{coffcode.h} if your version of coff is too wild. |
| 64 | |
| 65 | You can verify that your new BFD backend works quite simply by |
| 66 | building @file{objdump} from the @file{binutils} directory, |
| 67 | and making sure that its version of what's going on and your |
| 68 | host system's idea (assuming it has the pretty standard coff |
| 69 | dump utility, usually called @code{att-dump} or just |
| 70 | @code{dump}) are the same. Then clean up your code, and send |
| 71 | what you've done to Cygnus. Then your stuff will be in the |
| 72 | next release, and you won't have to keep integrating it. |
| 73 | |
| 74 | SUBSECTION |
| 75 | How the coff backend works |
| 76 | |
| 77 | SUBSUBSECTION |
| 78 | File layout |
| 79 | |
| 80 | The Coff backend is split into generic routines that are |
| 81 | applicable to any Coff target and routines that are specific |
| 82 | to a particular target. The target-specific routines are |
| 83 | further split into ones which are basically the same for all |
| 84 | Coff targets except that they use the external symbol format |
| 85 | or use different values for certain constants. |
| 86 | |
| 87 | The generic routines are in @file{coffgen.c}. These routines |
| 88 | work for any Coff target. They use some hooks into the target |
| 89 | specific code; the hooks are in a @code{bfd_coff_backend_data} |
| 90 | structure, one of which exists for each target. |
| 91 | |
| 92 | The essentially similar target-specific routines are in |
| 93 | @file{coffcode.h}. This header file includes executable C code. |
| 94 | The various Coff targets first include the appropriate Coff |
| 95 | header file, make any special defines that are needed, and |
| 96 | then include @file{coffcode.h}. |
| 97 | |
| 98 | Some of the Coff targets then also have additional routines in |
| 99 | the target source file itself. |
| 100 | |
| 101 | For example, @file{coff-i960.c} includes |
| 102 | @file{coff/internal.h} and @file{coff/i960.h}. It then |
| 103 | defines a few constants, such as @code{I960}, and includes |
| 104 | @file{coffcode.h}. Since the i960 has complex relocation |
| 105 | types, @file{coff-i960.c} also includes some code to |
| 106 | manipulate the i960 relocs. This code is not in |
| 107 | @file{coffcode.h} because it would not be used by any other |
| 108 | target. |
| 109 | |
| 110 | SUBSUBSECTION |
| 111 | Bit twiddling |
| 112 | |
| 113 | Each flavour of coff supported in BFD has its own header file |
| 114 | describing the external layout of the structures. There is also |
| 115 | an internal description of the coff layout, in |
| 116 | @file{coff/internal.h}. A major function of the |
| 117 | coff backend is swapping the bytes and twiddling the bits to |
| 118 | translate the external form of the structures into the normal |
| 119 | internal form. This is all performed in the |
| 120 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some |
| 121 | elements are different sizes between different versions of |
| 122 | coff; it is the duty of the coff version specific include file |
| 123 | to override the definitions of various packing routines in |
| 124 | @file{coffcode.h}. E.g., the size of line number entry in coff is |
| 125 | sometimes 16 bits, and sometimes 32 bits. @code{#define}ing |
| 126 | @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the |
| 127 | correct one. No doubt, some day someone will find a version of |
| 128 | coff which has a varying field size not catered to at the |
| 129 | moment. To port BFD, that person will have to add more @code{#defines}. |
| 130 | Three of the bit twiddling routines are exported to |
| 131 | @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} |
| 132 | and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol |
| 133 | table on its own, but uses BFD to fix things up. More of the |
| 134 | bit twiddlers are exported for @code{gas}; |
| 135 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, |
| 136 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, |
| 137 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, |
| 138 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track |
| 139 | of all the symbol table and reloc drudgery itself, thereby |
| 140 | saving the internal BFD overhead, but uses BFD to swap things |
| 141 | on the way out, making cross ports much safer. Doing so also |
| 142 | allows BFD (and thus the linker) to use the same header files |
| 143 | as @code{gas}, which makes one avenue to disaster disappear. |
| 144 | |
| 145 | SUBSUBSECTION |
| 146 | Symbol reading |
| 147 | |
| 148 | The simple canonical form for symbols used by BFD is not rich |
| 149 | enough to keep all the information available in a coff symbol |
| 150 | table. The back end gets around this problem by keeping the original |
| 151 | symbol table around, "behind the scenes". |
| 152 | |
| 153 | When a symbol table is requested (through a call to |
| 154 | @code{bfd_canonicalize_symtab}), a request gets through to |
| 155 | @code{coff_get_normalized_symtab}. This reads the symbol table from |
| 156 | the coff file and swaps all the structures inside into the |
| 157 | internal form. It also fixes up all the pointers in the table |
| 158 | (represented in the file by offsets from the first symbol in |
| 159 | the table) into physical pointers to elements in the new |
| 160 | internal table. This involves some work since the meanings of |
| 161 | fields change depending upon context: a field that is a |
| 162 | pointer to another structure in the symbol table at one moment |
| 163 | may be the size in bytes of a structure at the next. Another |
| 164 | pass is made over the table. All symbols which mark file names |
| 165 | (<<C_FILE>> symbols) are modified so that the internal |
| 166 | string points to the value in the auxent (the real filename) |
| 167 | rather than the normal text associated with the symbol |
| 168 | (@code{".file"}). |
| 169 | |
| 170 | At this time the symbol names are moved around. Coff stores |
| 171 | all symbols less than nine characters long physically |
| 172 | within the symbol table; longer strings are kept at the end of |
| 173 | the file in the string table. This pass moves all strings |
| 174 | into memory and replaces them with pointers to the strings. |
| 175 | |
| 176 | The symbol table is massaged once again, this time to create |
| 177 | the canonical table used by the BFD application. Each symbol |
| 178 | is inspected in turn, and a decision made (using the |
| 179 | @code{sclass} field) about the various flags to set in the |
| 180 | @code{asymbol}. @xref{Symbols}. The generated canonical table |
| 181 | shares strings with the hidden internal symbol table. |
| 182 | |
| 183 | Any linenumbers are read from the coff file too, and attached |
| 184 | to the symbols which own the functions the linenumbers belong to. |
| 185 | |
| 186 | SUBSUBSECTION |
| 187 | Symbol writing |
| 188 | |
| 189 | Writing a symbol to a coff file which didn't come from a coff |
| 190 | file will lose any debugging information. The @code{asymbol} |
| 191 | structure remembers the BFD from which the symbol was taken, and on |
| 192 | output the back end makes sure that the same destination target as |
| 193 | source target is present. |
| 194 | |
| 195 | When the symbols have come from a coff file then all the |
| 196 | debugging information is preserved. |
| 197 | |
| 198 | Symbol tables are provided for writing to the back end in a |
| 199 | vector of pointers to pointers. This allows applications like |
| 200 | the linker to accumulate and output large symbol tables |
| 201 | without having to do too much byte copying. |
| 202 | |
| 203 | This function runs through the provided symbol table and |
| 204 | patches each symbol marked as a file place holder |
| 205 | (@code{C_FILE}) to point to the next file place holder in the |
| 206 | list. It also marks each @code{offset} field in the list with |
| 207 | the offset from the first symbol of the current symbol. |
| 208 | |
| 209 | Another function of this procedure is to turn the canonical |
| 210 | value form of BFD into the form used by coff. Internally, BFD |
| 211 | expects symbol values to be offsets from a section base; so a |
| 212 | symbol physically at 0x120, but in a section starting at |
| 213 | 0x100, would have the value 0x20. Coff expects symbols to |
| 214 | contain their final value, so symbols have their values |
| 215 | changed at this point to reflect their sum with their owning |
| 216 | section. This transformation uses the |
| 217 | <<output_section>> field of the @code{asymbol}'s |
| 218 | @code{asection} @xref{Sections}. |
| 219 | |
| 220 | o <<coff_mangle_symbols>> |
| 221 | |
| 222 | This routine runs though the provided symbol table and uses |
| 223 | the offsets generated by the previous pass and the pointers |
| 224 | generated when the symbol table was read in to create the |
| 225 | structured hierarchy required by coff. It changes each pointer |
| 226 | to a symbol into the index into the symbol table of the asymbol. |
| 227 | |
| 228 | o <<coff_write_symbols>> |
| 229 | |
| 230 | This routine runs through the symbol table and patches up the |
| 231 | symbols from their internal form into the coff way, calls the |
| 232 | bit twiddlers, and writes out the table to the file. |

| 4793 | |
| 4794 | o Turn the symbol referenced in the relocation's symbol index |
| 4795 | into a pointer into the canonical symbol table. |
| 4796 | This table is the same as the one returned by a call to |
| 4797 | @code{bfd_canonicalize_symtab}. The back end will call that |
| 4798 | routine and save the result if a canonicalization hasn't been done. |
| 4799 | |
| 4800 | o The reloc index is turned into a pointer to a howto |
| 4801 | structure, in a back end specific way. For instance, the 386 |
| 4802 | and 960 use the @code{r_type} to directly produce an index |
| 4803 | into a howto table vector; the 88k subtracts a number from the |
