1055 /* XCOFF archive support. 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.
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.
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.
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.
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.
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. */

3235 Simple positive relocation.
3238 Simple negative relocation.
3241 Simple PC relative relocation.
3244 TOC relative relocation. The value in the instruction in

3252 so we must change insn by on - in.
3255 GL linkage relocation. The value of this relocation
3256 is the address of the entry in the TOC section.
3259 Local object TOC address. I can't figure out the
3260 difference between this and case R_GL.
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.
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
3274 Absolute branch. We don't want to mess with the lower
3275 two bits of the instruction.
3278 The PowerPC ABI defines this as an absolute call which
3279 may be modified to become a relative call. The PowerOpen
