4 FIXME: Can someone provide a transliteration of this name into ASCII?
5 Using the following chars caused a compiler warning on HIUX (so I replaced

1055 /* XCOFF archive support. The original version of this code was by
1056 Damon A. Permezel. It was enhanced to permit cross support, and
1057 writing archive files, by Ian Lance Taylor, Cygnus Support.
1058
1059 XCOFF uses its own archive format. Everything is hooked together
1060 with file offset links, so it is possible to rapidly update an
1061 archive in place. Of course, we don't do that. An XCOFF archive
1062 has a real file header, not just an ARMAG string. The structure of
1063 the file header and of each archive header appear below.
1064
1065 An XCOFF archive also has a member table, which is a list of
1066 elements in the archive (you can get that by looking through the
1067 linked list, but you have to read a lot more of the file). The
1068 member table has a normal archive header with an empty name. It is
1069 normally (and perhaps must be) the second to last entry in the
1070 archive. The member table data is almost printable ASCII. It
1071 starts with a 12 character decimal string which is the number of
1072 entries in the table. For each entry it has a 12 character decimal
1073 string which is the offset in the archive of that member. These
1074 entries are followed by a series of null terminated strings which
1075 are the member names for each entry.
1076
1077 Finally, an XCOFF archive has a global symbol table, which is what
1078 we call the armap. The global symbol table has a normal archive
1079 header with an empty name. It is normally (and perhaps must be)
1080 the last entry in the archive. The contents start with a four byte
1081 binary number which is the number of entries. This is followed by
1082 a that many four byte binary numbers; each is the file offset of an
1083 entry in the archive. These numbers are followed by a series of
1084 null terminated strings, which are symbol names.
1085
1086 AIX 4.3 introduced a new archive format which can handle larger
1087 files and also 32- and 64-bit objects in the same archive. The
1088 things said above remain true except that there is now more than
1089 one global symbol table. The one is used to index 32-bit objects,
1090 the other for 64-bit objects.
1091
1092 The new archives (recognizable by the new ARMAG string) has larger
1093 field lengths so that we cannot really share any code. Also we have
1094 to take care that we are not generating the new form of archives
1095 on AIX 4.2 or earlier systems. */

3220 I took the relocation type definitions from two documents:
3221 the PowerPC AIX Version 4 Application Binary Interface, First
3222 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3223 32-Bit Hardware Implementation (June 30, 1994). Differences
3224 between the documents are noted below.
3225
3226 Unsupported r_type's
3227
3228 R_RTB:
3229 R_RRTBI:
3230 R_RRTBA:
3231
3232 These relocs are defined by the PowerPC ABI to be
3233 relative branches which use half of the difference
3234 between the symbol and the program counter. I can't
3235 quite figure out when this is useful. These relocs are
3236 not defined by the PowerOpen ABI.
3237
3238 Supported r_type's
3239
3240 R_POS:
3241 Simple positive relocation.
3242
3243 R_NEG:
3244 Simple negative relocation.
3245
3246 R_REL:
3247 Simple PC relative relocation.
3248
3249 R_TOC:
3250 TOC relative relocation. The value in the instruction in
3251 the input file is the offset from the input file TOC to
3252 the desired location. We want the offset from the final
3253 TOC to the desired location. We have:
3254 isym = iTOC + in
3255 iinsn = in + o
3256 osym = oTOC + on
3257 oinsn = on + o
3258 so we must change insn by on - in.
3259
3260 R_GL:
3261 GL linkage relocation. The value of this relocation
3262 is the address of the entry in the TOC section.
3263
3264 R_TCL:
3265 Local object TOC address. I can't figure out the
3266 difference between this and case R_GL.
3267
3268 R_TRL:
3269 TOC relative relocation. A TOC relative load instruction
3270 which may be changed to a load address instruction.
3271 FIXME: We don't currently implement this optimization.
3272
3273 R_TRLA:
3274 TOC relative relocation. This is a TOC relative load
3275 address instruction which may be changed to a load
3276 instruction. FIXME: I don't know if this is the correct
3277 implementation.
3278
3279 R_BA:
3280 Absolute branch. We don't want to mess with the lower
3281 two bits of the instruction.
3282
3283 R_CAI:
3284 The PowerPC ABI defines this as an absolute call which
3285 may be modified to become a relative call. The PowerOpen
3286 ABI does not define this relocation type.
3287
3288 R_RBA:
3289 Absolute branch which may be modified to become a
3290 relative branch.
3291
3292 R_RBAC:
3293 The PowerPC ABI defines this as an absolute branch to a
3294 fixed address which may be modified to an absolute branch
3295 to a symbol. The PowerOpen ABI does not define this
3296 relocation type.
3297
3298 R_RBRC:
3299 The PowerPC ABI defines this as an absolute branch to a
3300 fixed address which may be modified to a relative branch.
3301 The PowerOpen ABI does not define this relocation type.
3302
3303 R_BR:
3304 Relative branch. We don't want to mess with the lower
3305 two bits of the instruction.
3306
3307 R_CREL:
3308 The PowerPC ABI defines this as a relative call which may
3309 be modified to become an absolute call. The PowerOpen
3310 ABI does not define this relocation type.
3311
3312 R_RBR:
3313 A relative branch which may be modified to become an
3314 absolute branch. FIXME: We don't implement this,
3315 although we should for symbols of storage mapping class
3316 XMC_XO.
3317
3318 R_RL:
3319 The PowerPC AIX ABI describes this as a load which may be
3320 changed to a load address. The PowerOpen ABI says this
3321 is the same as case R_POS.
3322
3323 R_RLA:
3324 The PowerPC AIX ABI describes this as a load address
3325 which may be changed to a load. The PowerOpen ABI says
3326 this is the same as R_POS.
