| 1160 | /* XCOFF archive support. The original version of this code was by |
| 1161 | Damon A. Permezel. It was enhanced to permit cross support, and |
| 1162 | writing archive files, by Ian Lance Taylor, Cygnus Support. |
| 1163 | |
| 1164 | XCOFF uses its own archive format. Everything is hooked together |
| 1165 | with file offset links, so it is possible to rapidly update an |
| 1166 | archive in place. Of course, we don't do that. An XCOFF archive |
| 1167 | has a real file header, not just an ARMAG string. The structure of |
| 1168 | the file header and of each archive header appear below. |
| 1169 | |
| 1170 | An XCOFF archive also has a member table, which is a list of |
| 1171 | elements in the archive (you can get that by looking through the |
| 1172 | linked list, but you have to read a lot more of the file). The |
| 1173 | member table has a normal archive header with an empty name. It is |
| 1174 | normally (and perhaps must be) the second to last entry in the |
| 1175 | archive. The member table data is almost printable ASCII. It |
| 1176 | starts with a 12 character decimal string which is the number of |
| 1177 | entries in the table. For each entry it has a 12 character decimal |
| 1178 | string which is the offset in the archive of that member. These |
| 1179 | entries are followed by a series of null terminated strings which |
| 1180 | are the member names for each entry. |
| 1181 | |
| 1182 | Finally, an XCOFF archive has a global symbol table, which is what |
| 1183 | we call the armap. The global symbol table has a normal archive |
| 1184 | header with an empty name. It is normally (and perhaps must be) |
| 1185 | the last entry in the archive. The contents start with a four byte |
| 1186 | binary number which is the number of entries. This is followed by |
| 1187 | a that many four byte binary numbers; each is the file offset of an |
| 1188 | entry in the archive. These numbers are followed by a series of |
| 1189 | null terminated strings, which are symbol names. |
| 1190 | |
| 1191 | AIX 4.3 introduced a new archive format which can handle larger |
| 1192 | files and also 32- and 64-bit objects in the same archive. The |
| 1193 | things said above remain true except that there is now more than |
| 1194 | one global symbol table. The one is used to index 32-bit objects, |
| 1195 | the other for 64-bit objects. |
| 1196 | |
| 1197 | The new archives (recognizable by the new ARMAG string) has larger |
| 1198 | field lengths so that we cannot really share any code. Also we have |
| 1199 | to take care that we are not generating the new form of archives |
| 1200 | on AIX 4.2 or earlier systems. */ |

| 3208 | I took the relocation type definitions from two documents: |
| 3209 | the PowerPC AIX Version 4 Application Binary Interface, First |
| 3210 | Edition (April 1992), and the PowerOpen ABI, Big-Endian |
| 3211 | 32-Bit Hardware Implementation (June 30, 1994). Differences |
| 3212 | between the documents are noted below. |
| 3213 | |
| 3214 | Unsupported r_type's |
| 3215 | |
| 3216 | R_RTB: |
| 3217 | R_RRTBI: |
| 3218 | R_RRTBA: |
| 3219 | |
| 3220 | These relocs are defined by the PowerPC ABI to be |
| 3221 | relative branches which use half of the difference |
| 3222 | between the symbol and the program counter. I can't |
| 3223 | quite figure out when this is useful. These relocs are |
| 3224 | not defined by the PowerOpen ABI. |
| 3225 | |
| 3226 | Supported r_type's |
| 3227 | |
| 3228 | R_POS: |
| 3229 | Simple positive relocation. |
| 3230 | |
| 3231 | R_NEG: |
| 3232 | Simple negative relocation. |
| 3233 | |
| 3234 | R_REL: |
| 3235 | Simple PC relative relocation. |
| 3236 | |
| 3237 | R_TOC: |
| 3238 | TOC relative relocation. The value in the instruction in |
| 3239 | the input file is the offset from the input file TOC to |
| 3240 | the desired location. We want the offset from the final |
| 3241 | TOC to the desired location. We have: |
| 3242 | isym = iTOC + in |
| 3243 | iinsn = in + o |
| 3244 | osym = oTOC + on |
| 3245 | oinsn = on + o |
| 3246 | so we must change insn by on - in. |
| 3247 | |
| 3248 | R_GL: |
| 3249 | GL linkage relocation. The value of this relocation |
| 3250 | is the address of the entry in the TOC section. |
| 3251 | |
| 3252 | R_TCL: |
| 3253 | Local object TOC address. I can't figure out the |
| 3254 | difference between this and case R_GL. |
| 3255 | |
| 3256 | R_TRL: |
| 3257 | TOC relative relocation. A TOC relative load instruction |
| 3258 | which may be changed to a load address instruction. |
| 3259 | FIXME: We don't currently implement this optimization. |
| 3260 | |
| 3261 | R_TRLA: |
| 3262 | TOC relative relocation. This is a TOC relative load |
| 3263 | address instruction which may be changed to a load |
| 3264 | instruction. FIXME: I don't know if this is the correct |
| 3265 | implementation. |
| 3266 | |
| 3267 | R_BA: |
| 3268 | Absolute branch. We don't want to mess with the lower |
| 3269 | two bits of the instruction. |
| 3270 | |
| 3271 | R_CAI: |
| 3272 | The PowerPC ABI defines this as an absolute call which |
| 3273 | may be modified to become a relative call. The PowerOpen |
| 3274 | ABI does not define this relocation type. |
| 3275 | |
| 3276 | R_RBA: |
| 3277 | Absolute branch which may be modified to become a |
| 3278 | relative branch. |
| 3279 | |
| 3280 | R_RBAC: |
| 3281 | The PowerPC ABI defines this as an absolute branch to a |
| 3282 | fixed address which may be modified to an absolute branch |
| 3283 | to a symbol. The PowerOpen ABI does not define this |
| 3284 | relocation type. |
| 3285 | |
| 3286 | R_RBRC: |
| 3287 | The PowerPC ABI defines this as an absolute branch to a |
| 3288 | fixed address which may be modified to a relative branch. |
| 3289 | The PowerOpen ABI does not define this relocation type. |
| 3290 | |
| 3291 | R_BR: |
| 3292 | Relative branch. We don't want to mess with the lower |
| 3293 | two bits of the instruction. |
| 3294 | |
| 3295 | R_CREL: |
| 3296 | The PowerPC ABI defines this as a relative call which may |
| 3297 | be modified to become an absolute call. The PowerOpen |
| 3298 | ABI does not define this relocation type. |
| 3299 | |
| 3300 | R_RBR: |
| 3301 | A relative branch which may be modified to become an |
| 3302 | absolute branch. |
| 3303 | |
| 3304 | R_RL: |
| 3305 | The PowerPC AIX ABI describes this as a load which may be |
| 3306 | changed to a load address. The PowerOpen ABI says this |
| 3307 | is the same as case R_POS. |
| 3308 | |
| 3309 | R_RLA: |
| 3310 | The PowerPC AIX ABI describes this as a load address |
| 3311 | which may be changed to a load. The PowerOpen ABI says |
| 3312 | this is the same as R_POS. |
