1188 | /* XCOFF archive support. The original version of this code was by | |
1189 | Damon A. Permezel. It was enhanced to permit cross support, and | |
1190 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
1191 | ||
1192 | XCOFF uses its own archive format. Everything is hooked together | |
1193 | with file offset links, so it is possible to rapidly update an | |
1194 | archive in place. Of course, we don't do that. An XCOFF archive | |
1195 | has a real file header, not just an ARMAG string. The structure of | |
1196 | the file header and of each archive header appear below. | |
1197 | ||
1198 | An XCOFF archive also has a member table, which is a list of | |
1199 | elements in the archive (you can get that by looking through the | |
1200 | linked list, but you have to read a lot more of the file). The | |
1201 | member table has a normal archive header with an empty name. It is | |
1202 | normally (and perhaps must be) the second to last entry in the | |
1203 | archive. The member table data is almost printable ASCII. It | |
1204 | starts with a 12 character decimal string which is the number of | |
1205 | entries in the table. For each entry it has a 12 character decimal | |
1206 | string which is the offset in the archive of that member. These | |
1207 | entries are followed by a series of null terminated strings which | |
1208 | are the member names for each entry. | |
1209 | ||
1210 | Finally, an XCOFF archive has a global symbol table, which is what | |
1211 | we call the armap. The global symbol table has a normal archive | |
1212 | header with an empty name. It is normally (and perhaps must be) | |
1213 | the last entry in the archive. The contents start with a four byte | |
1214 | binary number which is the number of entries. This is followed by | |
1215 | a that many four byte binary numbers; each is the file offset of an | |
1216 | entry in the archive. These numbers are followed by a series of | |
5ea1af0d GK |
1217 | null terminated strings, which are symbol names. |
1218 | ||
1219 | AIX 4.3 introduced a new archive format which can handle larger | |
1220 | files and also 32- and 64-bit objects in the same archive. The | |
1221 | things said above remain true except that there is now more than | |
1222 | one global symbol table. The one is used to index 32-bit objects, | |
1223 | the other for 64-bit objects. | |
1224 | ||
1225 | The new archives (recognizable by the new ARMAG string) has larger | |
1226 | field lengths so that we cannot really share any code. Also we have | |
1227 | to take care that we are not generating the new form of archives | |
1228 | on AIX 4.2 or earlier systems. */ | |

3260 | relative branches which use half of the difference | |
3261 | between the symbol and the program counter. I can't | |

3273 | R_REL: | |

3275 | ||
3276 | R_TOC: | |
3277 | TOC relative relocation. The value in the instruction in | |
3278 | the input file is the offset from the input file TOC to | |
3279 | the desired location. We want the offset from the final | |
3280 | TOC to the desired location. We have: | |
3281 | isym = iTOC + in | |
3282 | iinsn = in + o | |
3283 | osym = oTOC + on | |
3284 | oinsn = on + o | |
3285 | so we must change insn by on - in. | |
3286 | ||
3287 | R_GL: | |
3288 | GL linkage relocation. The value of this relocation | |
cf9ab45b | 3289 | is the address of the entry in the TOC section. |
