28 | coff backends | |
29 | ||
9fda1a39 | 30 | BFD supports a number of different flavours of coff format. |
c188b0be | 31 | The major differences between formats are the sizes and |
9fda1a39 | 32 | alignments of fields in structures on disk, and the occasional |
9783e04a | 33 | extra field. |
9fda1a39 | 34 | |
c188b0be | 35 | Coff in all its varieties is implemented with a few common |
9fda1a39 SC |
36 | files and a number of implementation specific files. For |
37 | example, The 88k bcs coff format is implemented in the file | |
c188b0be DM |
38 | @file{coff-m88k.c}. This file @code{#include}s |
39 | @file{coff/m88k.h} which defines the external structure of the | |
40 | coff format for the 88k, and @file{coff/internal.h} which | |
41 | defines the internal structure. @file{coff-m88k.c} also | |
075caafd ILT |
42 | defines the relocations used by the 88k format |
43 | @xref{Relocations}. | |
9fda1a39 SC |
44 | |
45 | The Intel i960 processor version of coff is implemented in | |
c188b0be DM |
46 | @file{coff-i960.c}. This file has the same structure as |
47 | @file{coff-m88k.c}, except that it includes @file{coff/i960.h} | |
9783e04a | 48 | rather than @file{coff-m88k.h}. |

c188b0be | 51 | Porting to a new version of coff |
9fda1a39 | 52 | |
9fda1a39 | 53 | The recommended method is to select from the existing |
c188b0be DM |
54 | implementations the version of coff which is most like the one |
55 | you want to use. For example, we'll say that i386 coff is | |
9fda1a39 | 56 | the one you select, and that your coff flavour is called foo. |
c188b0be DM |
57 | Copy @file{i386coff.c} to @file{foocoff.c}, copy |
58 | @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, | |
59 | and add the lines to @file{targets.c} and @file{Makefile.in} | |
9fda1a39 | 60 | so that your new back end is used. Alter the shapes of the |
c188b0be | 61 | structures in @file{../include/coff/foo.h} so that they match |
9fda1a39 | 62 | what you need. You will probably also have to add |
c188b0be | 63 | @code{#ifdef}s to the code in @file{coff/internal.h} and |
9783e04a | 64 | @file{coffcode.h} if your version of coff is too wild. |
9fda1a39 SC |
65 | |
66 | You can verify that your new BFD backend works quite simply by | |
c188b0be DM |
67 | building @file{objdump} from the @file{binutils} directory, |
68 | and making sure that its version of what's going on and your | |
69 | host system's idea (assuming it has the pretty standard coff | |
70 | dump utility, usually called @code{att-dump} or just | |
71 | @code{dump}) are the same. Then clean up your code, and send | |
9fda1a39 SC |
72 | what you've done to Cygnus. Then your stuff will be in the |
73 | next release, and you won't have to keep integrating it. | |

c188b0be | 76 | How the coff backend works |
9fda1a39 | 77 | |
075caafd | 78 | SUBSUBSECTION |
c188b0be | 79 | File layout |
075caafd ILT |
80 | |
81 | The Coff backend is split into generic routines that are | |
82 | applicable to any Coff target and routines that are specific | |
83 | to a particular target. The target-specific routines are | |
84 | further split into ones which are basically the same for all | |
85 | Coff targets except that they use the external symbol format | |
86 | or use different values for certain constants. | |
87 | ||
88 | The generic routines are in @file{coffgen.c}. These routines | |
89 | work for any Coff target. They use some hooks into the target | |
90 | specific code; the hooks are in a @code{bfd_coff_backend_data} | |
91 | structure, one of which exists for each target. | |
92 | ||
93 | The essentially similar target-specific routines are in | |
c188b0be | 94 | @file{coffcode.h}. This header file includes executable C code. |
075caafd ILT |
95 | The various Coff targets first include the appropriate Coff |
96 | header file, make any special defines that are needed, and | |
97 | then include @file{coffcode.h}. | |
98 | ||
99 | Some of the Coff targets then also have additional routines in | |
100 | the target source file itself. | |
101 | ||
102 | For example, @file{coff-i960.c} includes | |
103 | @file{coff/internal.h} and @file{coff/i960.h}. It then | |
104 | defines a few constants, such as @code{I960}, and includes | |
105 | @file{coffcode.h}. Since the i960 has complex relocation | |
106 | types, @file{coff-i960.c} also includes some code to | |
107 | manipulate the i960 relocs. This code is not in | |
108 | @file{coffcode.h} because it would not be used by any other | |
109 | target. | |

c188b0be | 112 | Bit twiddling |
9fda1a39 | 113 | |
9fda1a39 | 114 | Each flavour of coff supported in BFD has its own header file |
c188b0be DM |
115 | describing the external layout of the structures. There is also |
116 | an internal description of the coff layout, in | |
117 | @file{coff/internal.h}. A major function of the | |
9fda1a39 SC |
118 | coff backend is swapping the bytes and twiddling the bits to |
119 | translate the external form of the structures into the normal | |
120 | internal form. This is all performed in the | |
121 | @code{bfd_swap}_@i{thing}_@i{direction} routines. Some | |
122 | elements are different sizes between different versions of | |
c188b0be | 123 | coff; it is the duty of the coff version specific include file |
9fda1a39 | 124 | to override the definitions of various packing routines in |
c188b0be | 125 | @file{coffcode.h}. E.g., the size of line number entry in coff is |
9fda1a39 SC |
126 | sometimes 16 bits, and sometimes 32 bits. @code{#define}ing |
127 | @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the | |
128 | correct one. No doubt, some day someone will find a version of | |
c188b0be | 129 | coff which has a varying field size not catered to at the |
9783e04a | 130 | moment. To port BFD, that person will have to add more @code{#defines}. |
9fda1a39 SC |
131 | Three of the bit twiddling routines are exported to |
132 | @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} | |
133 | and @code{coff_swap_linno_in}. @code{GDB} reads the symbol | |
134 | table on its own, but uses BFD to fix things up. More of the | |
135 | bit twiddlers are exported for @code{gas}; | |
136 | @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, | |
137 | @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, | |
138 | @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, | |
139 | @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track | |
140 | of all the symbol table and reloc drudgery itself, thereby | |
141 | saving the internal BFD overhead, but uses BFD to swap things | |
c188b0be | 142 | on the way out, making cross ports much safer. Doing so also |
9fda1a39 SC |
143 | allows BFD (and thus the linker) to use the same header files |
144 | as @code{gas}, which makes one avenue to disaster disappear. | |

146 | SUBSUBSECTION | |
c188b0be | 147 | Symbol reading |
9fda1a39 | 148 | |
9fda1a39 SC |
149 | The simple canonical form for symbols used by BFD is not rich |
150 | enough to keep all the information available in a coff symbol | |
c188b0be | 151 | table. The back end gets around this problem by keeping the original |
9783e04a | 152 | symbol table around, "behind the scenes". |
9fda1a39 SC |
153 | |
154 | When a symbol table is requested (through a call to | |
c188b0be | 155 | @code{bfd_canonicalize_symtab}), a request gets through to |
075caafd | 156 | @code{coff_get_normalized_symtab}. This reads the symbol table from |
9fda1a39 SC |
157 | the coff file and swaps all the structures inside into the |
158 | internal form. It also fixes up all the pointers in the table | |
159 | (represented in the file by offsets from the first symbol in | |
160 | the table) into physical pointers to elements in the new | |
161 | internal table. This involves some work since the meanings of | |
c188b0be | 162 | fields change depending upon context: a field that is a |
9fda1a39 | 163 | pointer to another structure in the symbol table at one moment |
c188b0be | 164 | may be the size in bytes of a structure at the next. Another |
9fda1a39 | 165 | pass is made over the table. All symbols which mark file names |
616ebcfd | 166 | (<<C_FILE>> symbols) are modified so that the internal |
9fda1a39 SC |
167 | string points to the value in the auxent (the real filename) |
168 | rather than the normal text associated with the symbol | |
9783e04a | 169 | (@code{".file"}). |
9fda1a39 SC |
170 | |
171 | At this time the symbol names are moved around. Coff stores | |
172 | all symbols less than nine characters long physically | |
c188b0be | 173 | within the symbol table; longer strings are kept at the end of |
9fda1a39 | 174 | the file in the string table. This pass moves all strings |
c188b0be | 175 | into memory and replaces them with pointers to the strings. |
9fda1a39 SC |
176 | |
177 | ||
178 | The symbol table is massaged once again, this time to create | |
179 | the canonical table used by the BFD application. Each symbol | |
180 | is inspected in turn, and a decision made (using the | |
181 | @code{sclass} field) about the various flags to set in the | |
c188b0be | 182 | @code{asymbol}. @xref{Symbols}. The generated canonical table |
9783e04a | 183 | shares strings with the hidden internal symbol table. |
9fda1a39 SC |
184 | |
185 | Any linenumbers are read from the coff file too, and attached | |
9783e04a | 186 | to the symbols which own the functions the linenumbers belong to. |
9fda1a39 SC |

c188b0be | 189 | Symbol writing |
9fda1a39 | 190 | |
9fda1a39 SC |
191 | Writing a symbol to a coff file which didn't come from a coff |
192 | file will lose any debugging information. The @code{asymbol} | |
c188b0be DM |
193 | structure remembers the BFD from which the symbol was taken, and on |
194 | output the back end makes sure that the same destination target as | |
9fda1a39 SC |
195 | source target is present. |
196 | ||
197 | When the symbols have come from a coff file then all the | |
198 | debugging information is preserved. | |
199 | ||
200 | Symbol tables are provided for writing to the back end in a | |
201 | vector of pointers to pointers. This allows applications like | |
202 | the linker to accumulate and output large symbol tables | |
203 | without having to do too much byte copying. | |
204 | ||
9fda1a39 SC |
205 | This function runs through the provided symbol table and |
206 | patches each symbol marked as a file place holder | |
207 | (@code{C_FILE}) to point to the next file place holder in the | |
208 | list. It also marks each @code{offset} field in the list with | |
209 | the offset from the first symbol of the current symbol. | |
210 | ||
211 | Another function of this procedure is to turn the canonical | |
212 | value form of BFD into the form used by coff. Internally, BFD | |
213 | expects symbol values to be offsets from a section base; so a | |
214 | symbol physically at 0x120, but in a section starting at | |
215 | 0x100, would have the value 0x20. Coff expects symbols to | |
216 | contain their final value, so symbols have their values | |
217 | changed at this point to reflect their sum with their owning | |
c188b0be | 218 | section. This transformation uses the |
9fda1a39 | 219 | <<output_section>> field of the @code{asymbol}'s |
9783e04a | 220 | @code{asection} @xref{Sections}. |

c188b0be | 222 | o <<coff_mangle_symbols>> |
616ebcfd | 223 | |
9fda1a39 SC |
224 | This routine runs though the provided symbol table and uses |
225 | the offsets generated by the previous pass and the pointers | |
226 | generated when the symbol table was read in to create the | |
227 | structured hierachy required by coff. It changes each pointer | |
c188b0be | 228 | to a symbol into the index into the symbol table of the asymbol. |

9fda1a39 SC |
1897 | Creating the linenumber table is done by reading in the entire |
1898 | coff linenumber table, and creating another table for internal use. | |
6f715d66 | 1899 | |
c188b0be | 1900 | A coff linenumber table is structured so that each function |
9fda1a39 SC |
1901 | is marked as having a line number of 0. Each line within the |
1902 | function is an offset from the first line in the function. The | |
1903 | base of the line number information for the table is stored in | |
9783e04a | 1904 | the symbol associated with the function. |
6f715d66 | 1905 | |
9fda1a39 SC |
1906 | The information is copied from the external to the internal |
1907 | table, and each symbol which marks a function is marked by | |
1908 | pointing its... | |

9fda1a39 SC |
2241 | Coff relocations are easily transformed into the internal BFD form |
2242 | (@code{arelent}). | |
2243 | ||
2244 | Reading a coff relocation table is done in the following stages: | |
2245 | ||
c188b0be | 2246 | o Read the entire coff relocation table into memory. |
9fda1a39 | 2247 | |
c188b0be | 2248 | o Process each relocation in turn; first swap it from the |
9fda1a39 SC |
2249 | external to the internal form. |
2250 | ||
c188b0be DM |
2251 | o Turn the symbol referenced in the relocation's symbol index |
2252 | into a pointer into the canonical symbol table. | |
2253 | This table is the same as the one returned by a call to | |
2254 | @code{bfd_canonicalize_symtab}. The back end will call that | |
9fda1a39 SC |
2255 | routine and save the result if a canonicalization hasn't been done. |
2256 | ||
2257 | o The reloc index is turned into a pointer to a howto | |
2258 | structure, in a back end specific way. For instance, the 386 | |
2259 | and 960 use the @code{r_type} to directly produce an index | |
2260 | into a howto table vector; the 88k subtracts a number from the | |
2261 | @code{r_type} field and creates an addend field. | |
