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
6 them with octal escapes), and isn't useful without an understanding of what

1029 /* XCOFF archive support. The original version of this code was by
1030 Damon A. Permezel. It was enhanced to permit cross support, and
1031 writing archive files, by Ian Lance Taylor, Cygnus Support.
1032
1033 XCOFF uses its own archive format. Everything is hooked together
1034 with file offset links, so it is possible to rapidly update an
1035 archive in place. Of course, we don't do that. An XCOFF archive
1036 has a real file header, not just an ARMAG string. The structure of
1037 the file header and of each archive header appear below.
1038
1039 An XCOFF archive also has a member table, which is a list of
1040 elements in the archive (you can get that by looking through the
1041 linked list, but you have to read a lot more of the file). The
1042 member table has a normal archive header with an empty name. It is
1043 normally (and perhaps must be) the second to last entry in the
1044 archive. The member table data is almost printable ASCII. It
1045 starts with a 12 character decimal string which is the number of
1046 entries in the table. For each entry it has a 12 character decimal
1047 string which is the offset in the archive of that member. These
1048 entries are followed by a series of null terminated strings which
1049 are the member names for each entry.
1050
1051 Finally, an XCOFF archive has a global symbol table, which is what
1052 we call the armap. The global symbol table has a normal archive
1053 header with an empty name. It is normally (and perhaps must be)
1054 the last entry in the archive. The contents start with a four byte
1055 binary number which is the number of entries. This is followed by
1056 a that many four byte binary numbers; each is the file offset of an
1057 entry in the archive. These numbers are followed by a series of
1058 null terminated strings, which are symbol names.
1059
1060 AIX 4.3 introduced a new archive format which can handle larger
1061 files and also 32- and 64-bit objects in the same archive. The
1062 things said above remain true except that there is now more than
1063 one global symbol table. The one is used to index 32-bit objects,
1064 the other for 64-bit objects.
1065
1066 The new archives (recognizable by the new ARMAG string) has larger
1067 field lengths so that we cannot really share any code. Also we have
1068 to take care that we are not generating the new form of archives
1069 on AIX 4.2 or earlier systems. */

3193 I took the relocation type definitions from two documents:
3194 the PowerPC AIX Version 4 Application Binary Interface, First
3195 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3196 32-Bit Hardware Implementation (June 30, 1994). Differences
3197 between the documents are noted below.
3198
3199 Unsupported r_type's
3200
3201 R_RTB:
3202 R_RRTBI:
3203 R_RRTBA:
3204
3205 These relocs are defined by the PowerPC ABI to be
3206 relative branches which use half of the difference
3207 between the symbol and the program counter. I can't
3208 quite figure out when this is useful. These relocs are
3209 not defined by the PowerOpen ABI.
3210
3211 Supported r_type's
3212
3213 R_POS:
3214 Simple positive relocation.
3215
3216 R_NEG:
3217 Simple negative relocation.
3218
3219 R_REL:
3220 Simple PC relative relocation.
3221
3222 R_TOC:
3223 TOC relative relocation. The value in the instruction in
3224 the input file is the offset from the input file TOC to
3225 the desired location. We want the offset from the final
3226 TOC to the desired location. We have:
3227 isym = iTOC + in
3228 iinsn = in + o
3229 osym = oTOC + on
3230 oinsn = on + o
3231 so we must change insn by on - in.
3232
3233 R_GL:
3234 GL linkage relocation. The value of this relocation
3235 is the address of the entry in the TOC section.
3236
3237 R_TCL:
3238 Local object TOC address. I can't figure out the
3239 difference between this and case R_GL.
3240
3241 R_TRL:
3242 TOC relative relocation. A TOC relative load instruction
3243 which may be changed to a load address instruction.
3244 FIXME: We don't currently implement this optimization.
3245
3246 R_TRLA:
3247 TOC relative relocation. This is a TOC relative load
3248 address instruction which may be changed to a load
3249 instruction. FIXME: I don't know if this is the correct
3250 implementation.
3251
3252 R_BA:
3253 Absolute branch. We don't want to mess with the lower
3254 two bits of the instruction.
3255
3256 R_CAI:
3257 The PowerPC ABI defines this as an absolute call which
3258 may be modified to become a relative call. The PowerOpen
3259 ABI does not define this relocation type.
3260
3261 R_RBA:
3262 Absolute branch which may be modified to become a
3263 relative branch.
3264
3265 R_RBAC:
3266 The PowerPC ABI defines this as an absolute branch to a
3267 fixed address which may be modified to an absolute branch
3268 to a symbol. The PowerOpen ABI does not define this
3269 relocation type.
3270
3271 R_RBRC:
3272 The PowerPC ABI defines this as an absolute branch to a
3273 fixed address which may be modified to a relative branch.
3274 The PowerOpen ABI does not define this relocation type.
3275
3276 R_BR:
3277 Relative branch. We don't want to mess with the lower
3278 two bits of the instruction.
3279
3280 R_CREL:
3281 The PowerPC ABI defines this as a relative call which may
3282 be modified to become an absolute call. The PowerOpen
3283 ABI does not define this relocation type.
3284
3285 R_RBR:
3286 A relative branch which may be modified to become an
3287 absolute branch. FIXME: We don't implement this,
3288 although we should for symbols of storage mapping class
3289 XMC_XO.
3290
3291 R_RL:
3292 The PowerPC AIX ABI describes this as a load which may be
3293 changed to a load address. The PowerOpen ABI says this
3294 is the same as case R_POS.
3295
3296 R_RLA:
3297 The PowerPC AIX ABI describes this as a load address
3298 which may be changed to a load. The PowerOpen ABI says
3299 this is the same as R_POS.
