1020 | /* XCOFF archive support. The original version of this code was by | |
1021 | Damon A. Permezel. It was enhanced to permit cross support, and | |
1022 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
1023 | ||
1024 | XCOFF uses its own archive format. Everything is hooked together | |
1025 | with file offset links, so it is possible to rapidly update an | |
1026 | archive in place. Of course, we don't do that. An XCOFF archive | |
1027 | has a real file header, not just an ARMAG string. The structure of | |
1028 | the file header and of each archive header appear below. | |
1029 | ||
1030 | An XCOFF archive also has a member table, which is a list of | |
1031 | elements in the archive (you can get that by looking through the | |
1032 | linked list, but you have to read a lot more of the file). The | |
1033 | member table has a normal archive header with an empty name. It is | |
1034 | normally (and perhaps must be) the second to last entry in the | |
1035 | archive. The member table data is almost printable ASCII. It | |
1036 | starts with a 12 character decimal string which is the number of | |
1037 | entries in the table. For each entry it has a 12 character decimal | |
1038 | string which is the offset in the archive of that member. These | |
1039 | entries are followed by a series of null terminated strings which | |
1040 | are the member names for each entry. | |
1041 | ||
1042 | Finally, an XCOFF archive has a global symbol table, which is what | |
1043 | we call the armap. The global symbol table has a normal archive | |
1044 | header with an empty name. It is normally (and perhaps must be) | |
1045 | the last entry in the archive. The contents start with a four byte | |
1046 | binary number which is the number of entries. This is followed by | |
1047 | a that many four byte binary numbers; each is the file offset of an | |
1048 | entry in the archive. These numbers are followed by a series of | |
5ea1af0d GK |
1049 | null terminated strings, which are symbol names. |
1050 | ||
1051 | AIX 4.3 introduced a new archive format which can handle larger | |
1052 | files and also 32- and 64-bit objects in the same archive. The | |
1053 | things said above remain true except that there is now more than | |
1054 | one global symbol table. The one is used to index 32-bit objects, | |
1055 | the other for 64-bit objects. | |
1056 | ||
1057 | The new archives (recognizable by the new ARMAG string) has larger | |
1058 | field lengths so that we cannot really share any code. Also we have | |
1059 | to take care that we are not generating the new form of archives | |
1060 | on AIX 4.2 or earlier systems. */ | |

3188 | I took the relocation type definitions from two documents: |
3189 | the PowerPC AIX Version 4 Application Binary Interface, First | |
3190 | Edition (April 1992), and the PowerOpen ABI, Big-Endian | |
3191 | 32-Bit Hardware Implementation (June 30, 1994). Differences | |
3192 | between the documents are noted below. | |
3193 | ||
3194 | Unsupported r_type's | |
3195 | ||
3196 | R_RTB: | |
3197 | R_RRTBI: | |
3198 | R_RRTBA: | |
3199 | ||
3200 | These relocs are defined by the PowerPC ABI to be | |
3201 | relative branches which use half of the difference | |
3202 | between the symbol and the program counter. I can't | |
3203 | quite figure out when this is useful. These relocs are | |
3204 | not defined by the PowerOpen ABI. | |
3205 | ||
3206 | Supported r_type's | |
3207 | ||
3208 | R_POS: | |
3209 | Simple positive relocation. | |
3210 | ||
3211 | R_NEG: | |
3212 | Simple negative relocation. | |
3213 | ||
3214 | R_REL: | |
3215 | Simple PC relative relocation. | |
3216 | ||
3217 | R_TOC: | |
3218 | TOC relative relocation. The value in the instruction in | |
3219 | the input file is the offset from the input file TOC to | |
3220 | the desired location. We want the offset from the final | |
3221 | TOC to the desired location. We have: | |
3222 | isym = iTOC + in | |
3223 | iinsn = in + o | |
3224 | osym = oTOC + on | |
3225 | oinsn = on + o | |
3226 | so we must change insn by on - in. | |
3227 | ||
3228 | R_GL: | |
3229 | GL linkage relocation. The value of this relocation | |
3230 | is the address of the entry in the TOC section. | |
3231 | ||
3232 | R_TCL: | |
3233 | Local object TOC address. I can't figure out the | |
3234 | difference between this and case R_GL. | |
3235 | ||
3236 | R_TRL: | |
3237 | TOC relative relocation. A TOC relative load instruction | |
3238 | which may be changed to a load address instruction. | |
3239 | FIXME: We don't currently implement this optimization. | |
3240 | ||
3241 | R_TRLA: | |
3242 | TOC relative relocation. This is a TOC relative load | |
3243 | address instruction which may be changed to a load | |
3244 | instruction. FIXME: I don't know if this is the correct | |
3245 | implementation. | |
3246 | ||
3247 | R_BA: | |
3248 | Absolute branch. We don't want to mess with the lower | |
3249 | two bits of the instruction. | |
3250 | ||
3251 | R_CAI: | |
3252 | The PowerPC ABI defines this as an absolute call which | |
3253 | may be modified to become a relative call. The PowerOpen | |
3254 | ABI does not define this relocation type. | |
3255 | ||
3256 | R_RBA: | |
3257 | Absolute branch which may be modified to become a | |
3258 | relative branch. | |
3259 | ||
3260 | R_RBAC: | |
3261 | The PowerPC ABI defines this as an absolute branch to a | |
3262 | fixed address which may be modified to an absolute branch | |
3263 | to a symbol. The PowerOpen ABI does not define this | |
3264 | relocation type. | |
3265 | ||
3266 | R_RBRC: | |
3267 | The PowerPC ABI defines this as an absolute branch to a | |
3268 | fixed address which may be modified to a relative branch. | |
3269 | The PowerOpen ABI does not define this relocation type. | |
3270 | ||
3271 | R_BR: | |
3272 | Relative branch. We don't want to mess with the lower | |
3273 | two bits of the instruction. | |
3274 | ||
3275 | R_CREL: | |
3276 | The PowerPC ABI defines this as a relative call which may | |
3277 | be modified to become an absolute call. The PowerOpen | |
3278 | ABI does not define this relocation type. | |
3279 | ||
3280 | R_RBR: | |
3281 | A relative branch which may be modified to become an | |
3282 | absolute branch. FIXME: We don't implement this, | |
3283 | although we should for symbols of storage mapping class | |
3284 | XMC_XO. | |
3285 | ||
3286 | R_RL: | |
3287 | The PowerPC AIX ABI describes this as a load which may be | |
3288 | changed to a load address. The PowerOpen ABI says this | |
3289 | is the same as case R_POS. | |
3290 | ||
3291 | R_RLA: | |
3292 | The PowerPC AIX ABI describes this as a load address | |
3293 | which may be changed to a load. The PowerOpen ABI says | |
3294 | this is the same as R_POS. | |
