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. */

3219 I took the relocation type definitions from two documents:
3220 the PowerPC AIX Version 4 Application Binary Interface, First
3221 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3222 32-Bit Hardware Implementation (June 30, 1994). Differences
3223 between the documents are noted below.
3224
3225 Unsupported r_type's
3226
3227 R_RTB:
3228 R_RRTBI:
3229 R_RRTBA:
3230
3231 These relocs are defined by the PowerPC ABI to be
3232 relative branches which use half of the difference
3233 between the symbol and the program counter. I can't
3234 quite figure out when this is useful. These relocs are
3235 not defined by the PowerOpen ABI.
3236
3237 Supported r_type's
3238
3239 R_POS:
3240 Simple positive relocation.
3241
3242 R_NEG:
3243 Simple negative relocation.
3244
3245 R_REL:
3246 Simple PC relative relocation.
3247
3248 R_TOC:
3249 TOC relative relocation. The value in the instruction in
3250 the input file is the offset from the input file TOC to
3251 the desired location. We want the offset from the final
3252 TOC to the desired location. We have:
3253 isym = iTOC + in
3254 iinsn = in + o
3255 osym = oTOC + on
3256 oinsn = on + o
3257 so we must change insn by on - in.
3258
3259 R_GL:
3260 GL linkage relocation. The value of this relocation
3261 is the address of the entry in the TOC section.
3262
3263 R_TCL:
3264 Local object TOC address. I can't figure out the
3265 difference between this and case R_GL.
3266
3267 R_TRL:
3268 TOC relative relocation. A TOC relative load instruction
3269 which may be changed to a load address instruction.
3270 FIXME: We don't currently implement this optimization.
3271
3272 R_TRLA:
3273 TOC relative relocation. This is a TOC relative load
3274 address instruction which may be changed to a load
3275 instruction. FIXME: I don't know if this is the correct
3276 implementation.
3277
3278 R_BA:
3279 Absolute branch. We don't want to mess with the lower
3280 two bits of the instruction.
3281
3282 R_CAI:
3283 The PowerPC ABI defines this as an absolute call which
3284 may be modified to become a relative call. The PowerOpen
3285 ABI does not define this relocation type.
3286
3287 R_RBA:
3288 Absolute branch which may be modified to become a
3289 relative branch.
3290
3291 R_RBAC:
3292 The PowerPC ABI defines this as an absolute branch to a
3293 fixed address which may be modified to an absolute branch
3294 to a symbol. The PowerOpen ABI does not define this
3295 relocation type.
3296
3297 R_RBRC:
3298 The PowerPC ABI defines this as an absolute branch to a
3299 fixed address which may be modified to a relative branch.
3300 The PowerOpen ABI does not define this relocation type.
3301
3302 R_BR:
3303 Relative branch. We don't want to mess with the lower
3304 two bits of the instruction.
3305
3306 R_CREL:
3307 The PowerPC ABI defines this as a relative call which may
3308 be modified to become an absolute call. The PowerOpen
3309 ABI does not define this relocation type.
3310
3311 R_RBR:
3312 A relative branch which may be modified to become an
3313 absolute branch. FIXME: We don't implement this,
3314 although we should for symbols of storage mapping class
3315 XMC_XO.
3316
3317 R_RL:
3318 The PowerPC AIX ABI describes this as a load which may be
3319 changed to a load address. The PowerOpen ABI says this
3320 is the same as case R_POS.
3321
3322 R_RLA:
3323 The PowerPC AIX ABI describes this as a load address
3324 which may be changed to a load. The PowerOpen ABI says
3325 this is the same as R_POS.
