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. */

3212 I took the relocation type definitions from two documents:
3213 the PowerPC AIX Version 4 Application Binary Interface, First
3214 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3215 32-Bit Hardware Implementation (June 30, 1994). Differences
3216 between the documents are noted below.
3217
3218 Unsupported r_type's
3219
3220 R_RTB:
3221 R_RRTBI:
3222 R_RRTBA:
3223
3224 These relocs are defined by the PowerPC ABI to be
3225 relative branches which use half of the difference
3226 between the symbol and the program counter. I can't
3227 quite figure out when this is useful. These relocs are
3228 not defined by the PowerOpen ABI.
3229
3230 Supported r_type's
3231
3232 R_POS:
3233 Simple positive relocation.
3234
3235 R_NEG:
3236 Simple negative relocation.
3237
3238 R_REL:
3239 Simple PC relative relocation.
3240
3241 R_TOC:
3242 TOC relative relocation. The value in the instruction in
3243 the input file is the offset from the input file TOC to
3244 the desired location. We want the offset from the final
3245 TOC to the desired location. We have:
3246 isym = iTOC + in
3247 iinsn = in + o
3248 osym = oTOC + on
3249 oinsn = on + o
3250 so we must change insn by on - in.
3251
3252 R_GL:
3253 GL linkage relocation. The value of this relocation
3254 is the address of the entry in the TOC section.
3255
3256 R_TCL:
3257 Local object TOC address. I can't figure out the
3258 difference between this and case R_GL.
3259
3260 R_TRL:
3261 TOC relative relocation. A TOC relative load instruction
3262 which may be changed to a load address instruction.
3263 FIXME: We don't currently implement this optimization.
3264
3265 R_TRLA:
3266 TOC relative relocation. This is a TOC relative load
3267 address instruction which may be changed to a load
3268 instruction. FIXME: I don't know if this is the correct
3269 implementation.
3270
3271 R_BA:
3272 Absolute branch. We don't want to mess with the lower
3273 two bits of the instruction.
3274
3275 R_CAI:
3276 The PowerPC ABI defines this as an absolute call which
3277 may be modified to become a relative call. The PowerOpen
3278 ABI does not define this relocation type.
3279
3280 R_RBA:
3281 Absolute branch which may be modified to become a
3282 relative branch.
3283
3284 R_RBAC:
3285 The PowerPC ABI defines this as an absolute branch to a
3286 fixed address which may be modified to an absolute branch
3287 to a symbol. The PowerOpen ABI does not define this
3288 relocation type.
3289
3290 R_RBRC:
3291 The PowerPC ABI defines this as an absolute branch to a
3292 fixed address which may be modified to a relative branch.
3293 The PowerOpen ABI does not define this relocation type.
3294
3295 R_BR:
3296 Relative branch. We don't want to mess with the lower
3297 two bits of the instruction.
3298
3299 R_CREL:
3300 The PowerPC ABI defines this as a relative call which may
3301 be modified to become an absolute call. The PowerOpen
3302 ABI does not define this relocation type.
3303
3304 R_RBR:
3305 A relative branch which may be modified to become an
3306 absolute branch. FIXME: We don't implement this,
3307 although we should for symbols of storage mapping class
3308 XMC_XO.
3309
3310 R_RL:
3311 The PowerPC AIX ABI describes this as a load which may be
3312 changed to a load address. The PowerOpen ABI says this
3313 is the same as case R_POS.
3314
3315 R_RLA:
3316 The PowerPC AIX ABI describes this as a load address
3317 which may be changed to a load. The PowerOpen ABI says
3318 this is the same as R_POS.
