1073 /* XCOFF archive support. The original version of this code was by
1074 Damon A. Permezel. It was enhanced to permit cross support, and
1075 writing archive files, by Ian Lance Taylor, Cygnus Support.
1076
1077 XCOFF uses its own archive format. Everything is hooked together
1078 with file offset links, so it is possible to rapidly update an
1079 archive in place. Of course, we don't do that. An XCOFF archive
1080 has a real file header, not just an ARMAG string. The structure of
1081 the file header and of each archive header appear below.
1082
1083 An XCOFF archive also has a member table, which is a list of
1084 elements in the archive (you can get that by looking through the
1085 linked list, but you have to read a lot more of the file). The
1086 member table has a normal archive header with an empty name. It is
1087 normally (and perhaps must be) the second to last entry in the
1088 archive. The member table data is almost printable ASCII. It
1089 starts with a 12 character decimal string which is the number of
1090 entries in the table. For each entry it has a 12 character decimal
1091 string which is the offset in the archive of that member. These
1092 entries are followed by a series of null terminated strings which
1093 are the member names for each entry.
1094
1095 Finally, an XCOFF archive has a global symbol table, which is what
1096 we call the armap. The global symbol table has a normal archive
1097 header with an empty name. It is normally (and perhaps must be)
1098 the last entry in the archive. The contents start with a four byte
1099 binary number which is the number of entries. This is followed by
1100 a that many four byte binary numbers; each is the file offset of an
1101 entry in the archive. These numbers are followed by a series of
1102 null terminated strings, which are symbol names.
1103
1104 AIX 4.3 introduced a new archive format which can handle larger
1105 files and also 32- and 64-bit objects in the same archive. The
1106 things said above remain true except that there is now more than
1107 one global symbol table. The one is used to index 32-bit objects,
1108 the other for 64-bit objects.
1109
1110 The new archives (recognizable by the new ARMAG string) has larger
1111 field lengths so that we cannot really share any code. Also we have
1112 to take care that we are not generating the new form of archives
1113 on AIX 4.2 or earlier systems. */

3263 I took the relocation type definitions from two documents:
3264 the PowerPC AIX Version 4 Application Binary Interface, First
3265 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3266 32-Bit Hardware Implementation (June 30, 1994). Differences
3267 between the documents are noted below.
3268
3269 Unsupported r_type's
3270
3271 R_RTB:
3272 R_RRTBI:
3273 R_RRTBA:
3274
3275 These relocs are defined by the PowerPC ABI to be
3276 relative branches which use half of the difference
3277 between the symbol and the program counter. I can't
3278 quite figure out when this is useful. These relocs are
3279 not defined by the PowerOpen ABI.
3280
3281 Supported r_type's
3282
3283 R_POS:
3284 Simple positive relocation.
3285
3286 R_NEG:
3287 Simple negative relocation.
3288
3289 R_REL:
3290 Simple PC relative relocation.
3291
3292 R_TOC:
3293 TOC relative relocation. The value in the instruction in
3294 the input file is the offset from the input file TOC to
3295 the desired location. We want the offset from the final
3296 TOC to the desired location. We have:
3297 isym = iTOC + in
3298 iinsn = in + o
3299 osym = oTOC + on
3300 oinsn = on + o
3301 so we must change insn by on - in.
3302
3303 R_GL:
3304 GL linkage relocation. The value of this relocation
3305 is the address of the entry in the TOC section.
3306
3307 R_TCL:
3308 Local object TOC address. I can't figure out the
3309 difference between this and case R_GL.
3310
3311 R_TRL:
3312 TOC relative relocation. A TOC relative load instruction
3313 which may be changed to a load address instruction.
3314 FIXME: We don't currently implement this optimization.
3315
3316 R_TRLA:
3317 TOC relative relocation. This is a TOC relative load
3318 address instruction which may be changed to a load
3319 instruction. FIXME: I don't know if this is the correct
3320 implementation.
3321
3322 R_BA:
3323 Absolute branch. We don't want to mess with the lower
3324 two bits of the instruction.
3325
3326 R_CAI:
3327 The PowerPC ABI defines this as an absolute call which
3328 may be modified to become a relative call. The PowerOpen
3329 ABI does not define this relocation type.
3330
3331 R_RBA:
3332 Absolute branch which may be modified to become a
3333 relative branch.
3334
3335 R_RBAC:
3336 The PowerPC ABI defines this as an absolute branch to a
3337 fixed address which may be modified to an absolute branch
3338 to a symbol. The PowerOpen ABI does not define this
3339 relocation type.
3340
3341 R_RBRC:
3342 The PowerPC ABI defines this as an absolute branch to a
3343 fixed address which may be modified to a relative branch.
3344 The PowerOpen ABI does not define this relocation type.
3345
3346 R_BR:
3347 Relative branch. We don't want to mess with the lower
3348 two bits of the instruction.
3349
3350 R_CREL:
3351 The PowerPC ABI defines this as a relative call which may
3352 be modified to become an absolute call. The PowerOpen
3353 ABI does not define this relocation type.
3354
3355 R_RBR:
3356 A relative branch which may be modified to become an
3357 absolute branch.
3358
3359 R_RL:
3360 The PowerPC AIX ABI describes this as a load which may be
3361 changed to a load address. The PowerOpen ABI says this
3362 is the same as case R_POS.
3363
3364 R_RLA:
3365 The PowerPC AIX ABI describes this as a load address
3366 which may be changed to a load. The PowerOpen ABI says
3367 this is the same as R_POS.
