1066 /* XCOFF archive support. The original version of this code was by
1067 Damon A. Permezel. It was enhanced to permit cross support, and
1068 writing archive files, by Ian Lance Taylor, Cygnus Support.
1069
1070 XCOFF uses its own archive format. Everything is hooked together
1071 with file offset links, so it is possible to rapidly update an
1072 archive in place. Of course, we don't do that. An XCOFF archive
1073 has a real file header, not just an ARMAG string. The structure of
1074 the file header and of each archive header appear below.
1075
1076 An XCOFF archive also has a member table, which is a list of
1077 elements in the archive (you can get that by looking through the
1078 linked list, but you have to read a lot more of the file). The
1079 member table has a normal archive header with an empty name. It is
1080 normally (and perhaps must be) the second to last entry in the
1081 archive. The member table data is almost printable ASCII. It
1082 starts with a 12 character decimal string which is the number of
1083 entries in the table. For each entry it has a 12 character decimal
1084 string which is the offset in the archive of that member. These
1085 entries are followed by a series of null terminated strings which
1086 are the member names for each entry.
1087
1088 Finally, an XCOFF archive has a global symbol table, which is what
1089 we call the armap. The global symbol table has a normal archive
1090 header with an empty name. It is normally (and perhaps must be)
1091 the last entry in the archive. The contents start with a four byte
1092 binary number which is the number of entries. This is followed by
1093 a that many four byte binary numbers; each is the file offset of an
1094 entry in the archive. These numbers are followed by a series of
1095 null terminated strings, which are symbol names.
1096
1097 AIX 4.3 introduced a new archive format which can handle larger
1098 files and also 32- and 64-bit objects in the same archive. The
1099 things said above remain true except that there is now more than
1100 one global symbol table. The one is used to index 32-bit objects,
1101 the other for 64-bit objects.
1102
1103 The new archives (recognizable by the new ARMAG string) has larger
1104 field lengths so that we cannot really share any code. Also we have
1105 to take care that we are not generating the new form of archives
1106 on AIX 4.2 or earlier systems. */

3224 I took the relocation type definitions from two documents:
3225 the PowerPC AIX Version 4 Application Binary Interface, First
3226 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3227 32-Bit Hardware Implementation (June 30, 1994). Differences
3228 between the documents are noted below.
3229
3230 Unsupported r_type's
3231
3232 R_RTB:
3233 R_RRTBI:
3234 R_RRTBA:
3235
3236 These relocs are defined by the PowerPC ABI to be
3237 relative branches which use half of the difference
3238 between the symbol and the program counter. I can't
3239 quite figure out when this is useful. These relocs are
3240 not defined by the PowerOpen ABI.
3241
3242 Supported r_type's
3243
3244 R_POS:
3245 Simple positive relocation.
3246
3247 R_NEG:
3248 Simple negative relocation.
3249
3250 R_REL:
3251 Simple PC relative relocation.
3252
3253 R_TOC:
3254 TOC relative relocation. The value in the instruction in
3255 the input file is the offset from the input file TOC to
3256 the desired location. We want the offset from the final
3257 TOC to the desired location. We have:
3258 isym = iTOC + in
3259 iinsn = in + o
3260 osym = oTOC + on
3261 oinsn = on + o
3262 so we must change insn by on - in.
3263
3264 R_GL:
3265 GL linkage relocation. The value of this relocation
3266 is the address of the entry in the TOC section.
3267
3268 R_TCL:
3269 Local object TOC address. I can't figure out the
3270 difference between this and case R_GL.
3271
3272 R_TRL:
3273 TOC relative relocation. A TOC relative load instruction
3274 which may be changed to a load address instruction.
3275 FIXME: We don't currently implement this optimization.
3276
3277 R_TRLA:
3278 TOC relative relocation. This is a TOC relative load
3279 address instruction which may be changed to a load
3280 instruction. FIXME: I don't know if this is the correct
3281 implementation.
3282
3283 R_BA:
3284 Absolute branch. We don't want to mess with the lower
3285 two bits of the instruction.
3286
3287 R_CAI:
3288 The PowerPC ABI defines this as an absolute call which
3289 may be modified to become a relative call. The PowerOpen
3290 ABI does not define this relocation type.
3291
3292 R_RBA:
3293 Absolute branch which may be modified to become a
3294 relative branch.
3295
3296 R_RBAC:
3297 The PowerPC ABI defines this as an absolute branch to a
3298 fixed address which may be modified to an absolute branch
3299 to a symbol. The PowerOpen ABI does not define this
3300 relocation type.
3301
3302 R_RBRC:
3303 The PowerPC ABI defines this as an absolute branch to a
3304 fixed address which may be modified to a relative branch.
3305 The PowerOpen ABI does not define this relocation type.
3306
3307 R_BR:
3308 Relative branch. We don't want to mess with the lower
3309 two bits of the instruction.
3310
3311 R_CREL:
3312 The PowerPC ABI defines this as a relative call which may
3313 be modified to become an absolute call. The PowerOpen
3314 ABI does not define this relocation type.
3315
3316 R_RBR:
3317 A relative branch which may be modified to become an
3318 absolute branch. FIXME: We don't implement this,
3319 although we should for symbols of storage mapping class
3320 XMC_XO.
3321
3322 R_RL:
3323 The PowerPC AIX ABI describes this as a load which may be
3324 changed to a load address. The PowerOpen ABI says this
3325 is the same as case R_POS.
3326
3327 R_RLA:
3328 The PowerPC AIX ABI describes this as a load address
3329 which may be changed to a load. The PowerOpen ABI says
3330 this is the same as R_POS.
