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 3218 between the documents are noted below. 3219 3220 Unsupported r_type's 3221 3222 R_RTB: 3223 R_RRTBI: 3224 R_RRTBA: 3225 3226 These relocs are defined by the PowerPC ABI to be 3227 relative branches which use half of the difference 3228 between the symbol and the program counter. I can't 3229 quite figure out when this is useful. These relocs are 3230 not defined by the PowerOpen ABI. 3231 3232 Supported r_type's 3233 3234 R_POS: 3235 Simple positive relocation. 3236 3237 R_NEG: 3238 Simple negative relocation. 3239 3240 R_REL: 3241 Simple PC relative relocation. 3242 3243 R_TOC: 3244 TOC relative relocation. The value in the instruction in 3245 the input file is the offset from the input file TOC to 3246 the desired location. We want the offset from the final 3247 TOC to the desired location. We have: 3248 isym = iTOC + in 3249 iinsn = in + o 3250 osym = oTOC + on 3251 oinsn = on + o 3252 so we must change insn by on - in. 3253 3254 R_GL: 3255 GL linkage relocation. The value of this relocation 3256 is the address of the entry in the TOC section. 3257 3258 R_TCL: 3259 Local object TOC address. I can't figure out the 3260 difference between this and case R_GL. 3261 3262 R_TRL: 3263 TOC relative relocation. A TOC relative load instruction 3264 which may be changed to a load address instruction. 3265 FIXME: We don't currently implement this optimization. 3266 3267 R_TRLA: 3268 TOC relative relocation. This is a TOC relative load 3269 address instruction which may be changed to a load 3270 instruction. FIXME: I don't know if this is the correct 3271 implementation. 3272 3273 R_BA: 3274 Absolute branch. We don't want to mess with the lower 3275 two bits of the instruction. 3276 3277 R_CAI: 3278 The PowerPC ABI defines this as an absolute call which 3279 may be modified to become a relative call. The PowerOpen 3280 ABI does not define this relocation type. 3281 3282 R_RBA: 3283 Absolute branch which may be modified to become a 3284 relative branch. 3285 3286 R_RBAC: 3287 The PowerPC ABI defines this as an absolute branch to a 3288 fixed address which may be modified to an absolute branch 3289 to a symbol. The PowerOpen ABI does not define this 3290 relocation type. 3291 3292 R_RBRC: 3293 The PowerPC ABI defines this as an absolute branch to a 3294 fixed address which may be modified to a relative branch. 3295 The PowerOpen ABI does not define this relocation type. 3296 3297 R_BR: 3298 Relative branch. We don't want to mess with the lower 3299 two bits of the instruction. 3300 3301 R_CREL: 3302 The PowerPC ABI defines this as a relative call which may 3303 be modified to become an absolute call. The PowerOpen 3304 ABI does not define this relocation type. 3305 3306 R_RBR: 3307 A relative branch which may be modified to become an 3308 absolute branch. FIXME: We don't implement this, 3309 although we should for symbols of storage mapping class 3310 XMC_XO. 3311 3312 R_RL: 3313 The PowerPC AIX ABI describes this as a load which may be 3314 changed to a load address. The PowerOpen ABI says this 3315 is the same as case R_POS. 3316 3317 R_RLA: 3318 The PowerPC AIX ABI describes this as a load address 3319 which may be changed to a load. The PowerOpen ABI says 3320 this is the same as R_POS. 3321*/ 3322 3323bfd_boolean 3324xcoff_ppc_relocate_section (output_bfd, info, input_bfd, 3325 input_section, contents, relocs, syms, 3326 sections) 3327 bfd *output_bfd; 3328 struct bfd_link_info *info; 3329 bfd *input_bfd; 3330 asection *input_section; 3331 bfd_byte *contents; 3332 struct internal_reloc *relocs; 3333 struct internal_syment *syms; 3334 asection **sections; 3335{ 3336 struct internal_reloc *rel; 3337 struct internal_reloc *relend; 3338 3339 rel = relocs; 3340 relend = rel + input_section->reloc_count; 3341 for (; rel < relend; rel++) 3342 { 3343 long symndx; 3344 struct xcoff_link_hash_entry *h; 3345 struct internal_syment *sym; 3346 bfd_vma addend; 3347 bfd_vma val; 3348 struct reloc_howto_struct howto; 3349 bfd_vma relocation; 3350 bfd_vma value_to_relocate; 3351 bfd_vma address; 3352 bfd_byte *location; 3353 3354 /* Relocation type R_REF is a special relocation type which is 3355 merely used to prevent garbage collection from occurring for 3356 the csect including the symbol which it references. */ 3357 if (rel->r_type == R_REF) 3358 continue; 3359 3360 /* howto */ 3361 howto.type = rel->r_type; 3362 howto.rightshift = 0; 3363 howto.bitsize = (rel->r_size & 0x1f) + 1; 3364 howto.size = howto.bitsize > 16 ? 2 : 1; 3365 howto.pc_relative = FALSE; 3366 howto.bitpos = 0; 3367 howto.complain_on_overflow = (rel->r_size & 0x80 3368 ? complain_overflow_signed 3369 : complain_overflow_bitfield); 3370 howto.special_function = NULL; 3371 howto.name = "internal"; 3372 howto.partial_inplace = TRUE; 3373 howto.src_mask = howto.dst_mask = N_ONES (howto.bitsize); 3374 howto.pcrel_offset = FALSE; 3375 3376 /* symbol */ 3377 val = 0; 3378 addend = 0; 3379 h = NULL; 3380 sym = NULL; 3381 symndx = rel->r_symndx; 3382 3383 if (-1 != symndx) 3384 { 3385 asection *sec; 3386 3387 h = obj_xcoff_sym_hashes (input_bfd)[symndx]; 3388 sym = syms + symndx; 3389 addend = - sym->n_value; 3390 3391 if (NULL == h) 3392 { 3393 sec = sections[symndx]; 3394 /* Hack to make sure we use the right TOC anchor value 3395 if this reloc is against the TOC anchor. */ 3396 if (sec->name[3] == '0' 3397 && strcmp (sec->name, ".tc0") == 0) 3398 val = xcoff_data (output_bfd)->toc; 3399 else 3400 val = (sec->output_section->vma 3401 + sec->output_offset 3402 + sym->n_value 3403 - sec->vma); 3404 } 3405 else 3406 { 3407 if (h->root.type == bfd_link_hash_defined 3408 || h->root.type == bfd_link_hash_defweak) 3409 { 3410 sec = h->root.u.def.section; 3411 val = (h->root.u.def.value 3412 + sec->output_section->vma 3413 + sec->output_offset); 3414 } 3415 else if (h->root.type == bfd_link_hash_common) 3416 { 3417 sec = h->root.u.c.p->section; 3418 val = (sec->output_section->vma 3419 + sec->output_offset); 3420 3421 } 3422 else if ((0 == (h->flags & (XCOFF_DEF_DYNAMIC | XCOFF_IMPORT))) 3423 && ! info->relocatable) 3424 { 3425 if (!
