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. */

3513 The original version was based on two documents:
3514 the PowerPC AIX Version 4 Application Binary Interface, First
3515 Edition (April 1992), and the PowerOpen ABI, Big-Endian
3516 32-Bit Hardware Implementation (June 30, 1994). Differences
3517 between the documents are noted below.
3518 Now, IBM has released an official documentation about XCOFF
3520 https://www.ibm.com/support/knowledgecenter/ssw_aix_72/filesreference/XCOFF.html
3522 Unsupported r_type's
3528 These relocs are defined by the PowerPC ABI to be
3529 relative branches which use half of the difference
3530 between the symbol and the program counter. I can't
3531 quite figure out when this is useful. These relocs are
3532 not defined by the PowerOpen ABI.
3537 Simple positive relocation.
3540 Simple negative relocation.
3543 Simple PC relative relocation.
3546 TOC relative relocation. The value in the instruction in
3547 the input file is the offset from the input file TOC to
3548 the desired location. We want the offset from the final
3549 TOC to the desired location. We have:
3554 so we must change insn by on - in.
3555 This relocation allows the linker to perform optimizations
3556 by transforming a load instruction into a add-immediate
3557 when possible. The relocation is, then, changed to R_TRLA
3559 TODO: Currently, the optimisation isn't implemented.
3562 TOC relative relocation. Same as R_TOC, except that
3563 the optimization isn't allowed
3566 TOC relative relocation. This is a TOC relative load
3567 address instruction which have been changed to an add-
3568 immediate instruction.
3571 GL linkage relocation. The value of this relocation
3572 is the address of the external symbol in the TOC
3576 Local object TOC address. I can't figure out the
3577 difference between this and case R_GL.
3580 The PowerPC AIX ABI describes this as a load which may be
3581 changed to a load address. The PowerOpen ABI says this
3582 is the same as case R_POS.
3585 The PowerPC AIX ABI describes this as a load address
3586 which may be changed to a load. The PowerOpen ABI says
3587 this is the same as R_POS.
3590 Not a relocation but a way to prevent the garbage
3591 collector of AIX linker to remove symbols.
3592 This is not needed in our case.
3595 The PowerOpen ABI says this is the same as R_RBA.
3598 Absolute branch which may be modified to become a
3602 The PowerOpen ABI says this is the same as R_RBR.
3605 A relative branch which may be modified to become an
3609 The PowerPC ABI defines this as an absolute call which
3610 may be modified to become a relative call. The PowerOpen
3611 ABI does not define this relocation type.
3614 The PowerPC ABI defines this as a relative call which may
3615 be modified to become an absolute call. The PowerOpen
3616 ABI does not define this relocation type.
3619 The PowerPC ABI defines this as an absolute branch to a
3620 fixed address which may be modified to an absolute branch
3621 to a symbol. The PowerOpen ABI does not define this
3625 The PowerPC ABI defines this as an absolute branch to a
3626 fixed address which may be modified to a relative branch.
3627 The PowerOpen ABI does not define this relocation type.
3630 Thread-local storage relocation using general-dynamic
3634 Thread-local storage relocation using initial-exec model.
3637 Thread-local storage relocation using local-dynamic model.
3640 Thread-local storage relocation using local-exec model.
3643 Tread-local storage relocation used by the loader.
3646 Tread-local storage relocation used by the loader.
3649 Upper TOC relative relocation. The value is the
3650 high-order 16 bit of a TOC relative relocation.
3653 Lower TOC relative relocation. The value is the
3654 low-order 16 bit of a TOC relative relocation.
