1197 /* XCOFF archive support. The original version of this code was by
1198 Damon A. Permezel. It was enhanced to permit cross support, and
1199 writing archive files, by Ian Lance Taylor, Cygnus Support.
1200
1201 XCOFF uses its own archive format. Everything is hooked together
1202 with file offset links, so it is possible to rapidly update an
1203 archive in place. Of course, we don't do that. An XCOFF archive
1204 has a real file header, not just an ARMAG string. The structure of
1205 the file header and of each archive header appear below.
1206
1207 An XCOFF archive also has a member table, which is a list of
1208 elements in the archive (you can get that by looking through the
1209 linked list, but you have to read a lot more of the file). The
1210 member table has a normal archive header with an empty name. It is
1211 normally (and perhaps must be) the second to last entry in the
1212 archive. The member table data is almost printable ASCII. It
1213 starts with a 12 character decimal string which is the number of
1214 entries in the table. For each entry it has a 12 character decimal
1215 string which is the offset in the archive of that member. These
1216 entries are followed by a series of null terminated strings which
1217 are the member names for each entry.
1218
1219 Finally, an XCOFF archive has a global symbol table, which is what
1220 we call the armap. The global symbol table has a normal archive
1221 header with an empty name. It is normally (and perhaps must be)
1222 the last entry in the archive. The contents start with a four byte
1223 binary number which is the number of entries. This is followed by
1224 a that many four byte binary numbers; each is the file offset of an
1225 entry in the archive. These numbers are followed by a series of
1226 null terminated strings, which are symbol names.
1227
1228 AIX 4.3 introduced a new archive format which can handle larger
1229 files and also 32- and 64-bit objects in the same archive. The
1230 things said above remain true except that there is now more than
1231 one global symbol table. The one is used to index 32-bit objects,
1232 the other for 64-bit objects.
1233
1234 The new archives (recognizable by the new ARMAG string) has larger
1235 field lengths so that we cannot really share any code. Also we have
1236 to take care that we are not generating the new form of archives
1237 on AIX 4.2 or earlier systems. */

3236 I took the relocation type definitions from two documents:
3237 the PowerPC AIX Version 4 Application Binary Interface, First
3238 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3239 32-Bit Hardware Implementation (June 30, 1994). Differences
3240 between the documents are noted below.
3241
3242 Unsupported r_type's
3243
3244 R_RTB:
3245 R_RRTBI:
3246 R_RRTBA:
3247
3248 These relocs are defined by the PowerPC ABI to be
3249 relative branches which use half of the difference
3250 between the symbol and the program counter. I can't
3251 quite figure out when this is useful. These relocs are
3252 not defined by the PowerOpen ABI.
3253
3254 Supported r_type's
3255
3256 R_POS:
3257 Simple positive relocation.
3258
3259 R_NEG:
3260 Simple negative relocation.
3261
3262 R_REL:
3263 Simple PC relative relocation.
3264
3265 R_TOC:
3266 TOC relative relocation. The value in the instruction in
3267 the input file is the offset from the input file TOC to
3268 the desired location. We want the offset from the final
3269 TOC to the desired location. We have:
3270 isym = iTOC + in
3271 iinsn = in + o
3272 osym = oTOC + on
3273 oinsn = on + o
3274 so we must change insn by on - in.
3275
3276 R_GL:
3277 GL linkage relocation. The value of this relocation
3278 is the address of the entry in the TOC section.
3279
3280 R_TCL:
3281 Local object TOC address. I can't figure out the
3282 difference between this and case R_GL.
3283
3284 R_TRL:
3285 TOC relative relocation. A TOC relative load instruction
3286 which may be changed to a load address instruction.
3287 FIXME: We don't currently implement this optimization.
3288
3289 R_TRLA:
3290 TOC relative relocation. This is a TOC relative load
3291 address instruction which may be changed to a load
3292 instruction. FIXME: I don't know if this is the correct
3293 implementation.
3294
3295 R_BA:
3296 Absolute branch. We don't want to mess with the lower
3297 two bits of the instruction.
3298
3299 R_CAI:
3300 The PowerPC ABI defines this as an absolute call which
3301 may be modified to become a relative call. The PowerOpen
3302 ABI does not define this relocation type.
3303
3304 R_RBA:
3305 Absolute branch which may be modified to become a
3306 relative branch.
3307
3308 R_RBAC:
3309 The PowerPC ABI defines this as an absolute branch to a
3310 fixed address which may be modified to an absolute branch
3311 to a symbol. The PowerOpen ABI does not define this
3312 relocation type.
3313
3314 R_RBRC:
3315 The PowerPC ABI defines this as an absolute branch to a
3316 fixed address which may be modified to a relative branch.
3317 The PowerOpen ABI does not define this relocation type.
3318
3319 R_BR:
3320 Relative branch. We don't want to mess with the lower
3321 two bits of the instruction.
3322
3323 R_CREL:
3324 The PowerPC ABI defines this as a relative call which may
3325 be modified to become an absolute call. The PowerOpen
3326 ABI does not define this relocation type.
3327
3328 R_RBR:
3329 A relative branch which may be modified to become an
3330 absolute branch.
3331
3332 R_RL:
3333 The PowerPC AIX ABI describes this as a load which may be
3334 changed to a load address. The PowerOpen ABI says this
3335 is the same as case R_POS.
3336
3337 R_RLA:
3338 The PowerPC AIX ABI describes this as a load address
3339 which may be changed to a load. The PowerOpen ABI says
3340 this is the same as R_POS.
