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. */ 1096 1097/* XCOFF archives use this as a magic string.

Differences 3222 between the documents are noted below. 3223 3224 Unsupported r_type's 3225 3226 R_RTB: 3227 R_RRTBI: 3228 R_RRTBA: 3229 3230 These relocs are defined by the PowerPC ABI to be 3231 relative branches which use half of the difference 3232 between the symbol and the program counter. I can't 3233 quite figure out when this is useful. These relocs are 3234 not defined by the PowerOpen ABI. 3235 3236 Supported r_type's 3237 3238 R_POS: 3239 Simple positive relocation. 3240 3241 R_NEG: 3242 Simple negative relocation. 3243 3244 R_REL: 3245 Simple PC relative relocation. 3246 3247 R_TOC: 3248 TOC relative relocation. The value in the instruction in 3249 the input file is the offset from the input file TOC to 3250 the desired location. We want the offset from the final 3251 TOC to the desired location. We have: 3252 isym = iTOC + in 3253 iinsn = in + o 3254 osym = oTOC + on 3255 oinsn = on + o 3256 so we must change insn by on - in. 3257 3258 R_GL: 3259 GL linkage relocation. The value of this relocation 3260 is the address of the entry in the TOC section. 3261 3262 R_TCL: 3263 Local object TOC address. I can't figure out the 3264 difference between this and case R_GL. 3265 3266 R_TRL: 3267 TOC relative relocation. A TOC relative load instruction 3268 which may be changed to a load address instruction. 3269 FIXME: We don't currently implement this optimization. 3270 3271 R_TRLA: 3272 TOC relative relocation. This is a TOC relative load 3273 address instruction which may be changed to a load 3274 instruction. FIXME: I don't know if this is the correct 3275 implementation. 3276 3277 R_BA: 3278 Absolute branch. We don't want to mess with the lower 3279 two bits of the instruction. 3280 3281 R_CAI: 3282 The PowerPC ABI defines this as an absolute call which 3283 may be modified to become a relative call. The PowerOpen 3284 ABI does not define this relocation type. 3285 3286 R_RBA: 3287 Absolute branch which may be modified to become a 3288 relative branch. 3289 3290 R_RBAC: 3291 The PowerPC ABI defines this as an absolute branch to a 3292 fixed address which may be modified to an absolute branch 3293 to a symbol. The PowerOpen ABI does not define this 3294 relocation type. 3295 3296 R_RBRC: 3297 The PowerPC ABI defines this as an absolute branch to a 3298 fixed address which may be modified to a relative branch. 3299 The PowerOpen ABI does not define this relocation type. 3300 3301 R_BR: 3302 Relative branch. We don't want to mess with the lower 3303 two bits of the instruction. 3304 3305 R_CREL: 3306 The PowerPC ABI defines this as a relative call which may 3307 be modified to become an absolute call. The PowerOpen 3308 ABI does not define this relocation type. 3309 3310 R_RBR: 3311 A relative branch which may be modified to become an 3312 absolute branch. FIXME: We don't implement this, 3313 although we should for symbols of storage mapping class 3314 XMC_XO. 3315 3316 R_RL: 3317 The PowerPC AIX ABI describes this as a load which may be 3318 changed to a load address. The PowerOpen ABI says this 3319 is the same as case R_POS. 3320 3321 R_RLA: 3322 The PowerPC AIX ABI describes this as a load address 3323 which may be changed to a load. The PowerOpen ABI says 3324 this is the same as R_POS. 3325*/ 3326 3327bfd_boolean 3328xcoff_ppc_relocate_section (output_bfd, info, input_bfd, 3329 input_section, contents, relocs, syms, 3330 sections) 3331 bfd *output_bfd; 3332 struct bfd_link_info *info; 3333 bfd *input_bfd; 3334 asection *input_section; 3335 bfd_byte *contents; 3336 struct internal_reloc *relocs; 3337 struct internal_syment *syms; 3338 asection **sections; 3339{ 3340 struct internal_reloc *rel; 3341 struct internal_reloc *relend; 3342 3343 rel = relocs; 3344 relend = rel + input_section->reloc_count; 3345 for (; rel < relend; rel++) 3346 { 3347 long symndx; 3348 struct xcoff_link_hash_entry *h; 3349 struct internal_syment *sym; 3350 bfd_vma addend; 3351 bfd_vma val; 3352 struct reloc_howto_struct howto; 3353 bfd_vma relocation; 3354 bfd_vma value_to_relocate; 3355 bfd_vma address; 3356 bfd_byte *location; 3357 3358 /* Relocation type R_REF is a special relocation type which is 3359 merely used to prevent garbage collection from occurring for 3360 the csect including the symbol which it references. */ 3361 if (rel->r_type == R_REF) 3362 continue; 3363 3364 /* howto */ 3365 howto.type = rel->r_type; 3366 howto.rightshift = 0; 3367 howto.bitsize = (rel->r_size & 0x1f) + 1; 3368 howto.size = howto.bitsize > 16 ? 2 : 1; 3369 howto.pc_relative = FALSE; 3370 howto.bitpos = 0; 3371 howto.complain_on_overflow = (rel->r_size & 0x80 3372 ? complain_overflow_signed 3373 : complain_overflow_bitfield); 3374 howto.special_function = NULL; 3375 howto.name = "internal"; 3376 howto.partial_inplace = TRUE; 3377 howto.src_mask = howto.dst_mask = N_ONES (howto.bitsize); 3378 howto.pcrel_offset = FALSE; 3379 3380 /* symbol */ 3381 val = 0; 3382 addend = 0; 3383 h = NULL; 3384 sym = NULL; 3385 symndx = rel->r_symndx; 3386 3387 if (-1 != symndx) 3388 { 3389 asection *sec; 3390 3391 h = obj_xcoff_sym_hashes (input_bfd)[symndx]; 3392 sym = syms + symndx; 3393 addend = - sym->n_value; 3394 3395 if (NULL == h) 3396 { 3397 sec = sections[symndx]; 3398 /* Hack to make sure we use the right TOC anchor value 3399 if this reloc is against the TOC anchor. */ 3400 if (sec->name[3] == '0' 3401 && strcmp (sec->name, ".tc0") == 0) 3402 val = xcoff_data (output_bfd)->toc; 3403 else 3404 val = (sec->output_section->vma 3405 + sec->output_offset 3406 + sym->n_value 3407 - sec->vma); 3408 } 3409 else 3410 { 3411 if (h->root.type == bfd_link_hash_defined 3412 || h->root.type == bfd_link_hash_defweak) 3413 { 3414 sec = h->root.u.def.section; 3415 val = (h->root.u.def.value 3416 + sec->output_section->vma 3417 + sec->output_offset); 3418 } 3419 else if (h->root.type == bfd_link_hash_common) 3420 { 3421 sec = h->root.u.c.p->section; 3422 val = (sec->output_section->vma 3423 + sec->output_offset); 3424 3425 } 3426 else if ((0 == (h->flags & (XCOFF_DEF_DYNAMIC | XCOFF_IMPORT))) 3427 && ! info->relocatable) 3428 { 3429 if (!
