1249 /* XCOFF archive support. The original version of this code was by
1250 Damon A. Permezel. It was enhanced to permit cross support, and
1251 writing archive files, by Ian Lance Taylor, Cygnus Support.
1253 XCOFF uses its own archive format. Everything is hooked together
1254 with file offset links, so it is possible to rapidly update an
1255 archive in place. Of course, we don't do that. An XCOFF archive
1256 has a real file header, not just an ARMAG string. The structure of
1257 the file header and of each archive header appear below.
1259 An XCOFF archive also has a member table, which is a list of
1260 elements in the archive (you can get that by looking through the
1261 linked list, but you have to read a lot more of the file). The
1262 member table has a normal archive header with an empty name. It is
1263 normally (and perhaps must be) the second to last entry in the
1264 archive. The member table data is almost printable ASCII. It
1265 starts with a 12 character decimal string which is the number of
1266 entries in the table. For each entry it has a 12 character decimal
1267 string which is the offset in the archive of that member. These
1268 entries are followed by a series of null terminated strings which
1269 are the member names for each entry.
1271 Finally, an XCOFF archive has a global symbol table, which is what
1272 we call the armap. The global symbol table has a normal archive
1273 header with an empty name. It is normally (and perhaps must be)
1274 the last entry in the archive. The contents start with a four byte
1275 binary number which is the number of entries. This is followed by
1276 a that many four byte binary numbers; each is the file offset of an
1277 entry in the archive. These numbers are followed by a series of
1278 null terminated strings, which are symbol names.
1280 AIX 4.3 introduced a new archive format which can handle larger
1281 files and also 32- and 64-bit objects in the same archive. The
1282 things said above remain true except that there is now more than
1283 one global symbol table. The one is used to index 32-bit objects,
1284 the other for 64-bit objects.
1286 The new archives (recognizable by the new ARMAG string) has larger
1287 field lengths so that we cannot really share any code. Also we have
1288 to take care that we are not generating the new form of archives
1289 on AIX 4.2 or earlier systems. */
1291 /* PR 21786: The PE/COFF standard does not require NUL termination for any of
1292 the ASCII fields in the archive headers. So in order to be able to extract
1293 numerical values we provide our own versions of strtol and strtoll which
1294 take a maximum length as an additional parameter. Also - just to save space,
1295 we omit the endptr return parameter, since we know that it is never used. */

3495 The original version was based on two documents:
3496 the PowerPC AIX Version 4 Application Binary Interface, First
3497 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3498 32-Bit Hardware Implementation (June 30, 1994). Differences
3499 between the documents are noted below.
3500 Now, IBM has released an official documentation about XCOFF
3502 https://www.ibm.com/support/knowledgecenter/ssw_aix_72/filesreference/XCOFF.html
3504 Unsupported r_type's
3510 These relocs are defined by the PowerPC ABI to be
3511 relative branches which use half of the difference
3512 between the symbol and the program counter. I can't
3513 quite figure out when this is useful. These relocs are
3514 not defined by the PowerOpen ABI.
3519 Simple positive relocation.
3522 Simple negative relocation.
3525 Simple PC relative relocation.
3528 TOC relative relocation. The value in the instruction in
3529 the input file is the offset from the input file TOC to
3530 the desired location. We want the offset from the final
3531 TOC to the desired location. We have:
3536 so we must change insn by on - in.
3537 This relocation allows the linker to perform optimizations
3538 by transforming a load instruction into a add-immediate
3539 when possible. The relocation is, then, changed to R_TRLA
3541 TODO: Currently, the optimisation isn't implemented.
3544 TOC relative relocation. Same as R_TOC, except that
3545 the optimization isn't allowed
3548 TOC relative relocation. This is a TOC relative load
3549 address instruction which have been changed to an add-
3550 immediate instruction.
3553 GL linkage relocation. The value of this relocation
3554 is the address of the external symbol in the TOC
3558 Local object TOC address. I can't figure out the
3559 difference between this and case R_GL.
3562 The PowerPC AIX ABI describes this as a load which may be
3563 changed to a load address. The PowerOpen ABI says this
3564 is the same as case R_POS.
3567 The PowerPC AIX ABI describes this as a load address
3568 which may be changed to a load. The PowerOpen ABI says
3569 this is the same as R_POS.
3572 Not a relocation but a way to prevent the garbage
3573 collector of AIX linker to remove symbols.
3574 This is not needed in our case.
3577 The PowerOpen ABI says this is the same as R_RBA.
3580 Absolute branch which may be modified to become a
3584 The PowerOpen ABI says this is the same as R_RBR.
3587 A relative branch which may be modified to become an
3591 The PowerPC ABI defines this as an absolute call which
3592 may be modified to become a relative call. The PowerOpen
3593 ABI does not define this relocation type.
3596 The PowerPC ABI defines this as a relative call which may
3597 be modified to become an absolute call. The PowerOpen
3598 ABI does not define this relocation type.
3601 The PowerPC ABI defines this as an absolute branch to a
3602 fixed address which may be modified to an absolute branch
3603 to a symbol. The PowerOpen ABI does not define this
3607 The PowerPC ABI defines this as an absolute branch to a
3608 fixed address which may be modified to a relative branch.
3609 The PowerOpen ABI does not define this relocation type.
3612 Thread-local storage relocation using general-dynamic
3616 Thread-local storage relocation using initial-exec model.
3619 Thread-local storage relocation using local-dynamic model.
3622 Thread-local storage relocation using local-exec model.
3625 Tread-local storage relocation used by the loader.
3628 Tread-local storage relocation used by the loader.
3631 Upper TOC relative relocation. The value is the
3632 high-order 16 bit of a TOC relative relocation.
3635 Lower TOC relative relocation. The value is the
3636 low-order 16 bit of a TOC relative relocation.
