1066 /* XCOFF archive support. The original version of this code was by
1067 Damon A. Permezel. It was enhanced to permit cross support, and
1068 writing archive files, by Ian Lance Taylor, Cygnus Support.
1070 XCOFF uses its own archive format. Everything is hooked together
1071 with file offset links, so it is possible to rapidly update an
1072 archive in place. Of course, we don't do that. An XCOFF archive
1073 has a real file header, not just an ARMAG string. The structure of
1074 the file header and of each archive header appear below.
1076 An XCOFF archive also has a member table, which is a list of
1077 elements in the archive (you can get that by looking through the
1078 linked list, but you have to read a lot more of the file). The
1079 member table has a normal archive header with an empty name. It is
1080 normally (and perhaps must be) the second to last entry in the
1081 archive. The member table data is almost printable ASCII. It
1082 starts with a 12 character decimal string which is the number of
1083 entries in the table. For each entry it has a 12 character decimal
1084 string which is the offset in the archive of that member. These
1085 entries are followed by a series of null terminated strings which
1086 are the member names for each entry.
1088 Finally, an XCOFF archive has a global symbol table, which is what
1089 we call the armap. The global symbol table has a normal archive
1090 header with an empty name. It is normally (and perhaps must be)
1091 the last entry in the archive. The contents start with a four byte
1092 binary number which is the number of entries. This is followed by
1093 a that many four byte binary numbers; each is the file offset of an
1094 entry in the archive. These numbers are followed by a series of
1095 null terminated strings, which are symbol names.
1097 AIX 4.3 introduced a new archive format which can handle larger
1098 files and also 32- and 64-bit objects in the same archive. The
1099 things said above remain true except that there is now more than
1100 one global symbol table. The one is used to index 32-bit objects,
1101 the other for 64-bit objects.

3240 relative branches which use half of the difference
3241 between the symbol and the program counter. I can't
3242 quite figure out when this is useful. These relocs are
3243 not defined by the PowerOpen ABI.
3248 Simple positive relocation.
3251 Simple negative relocation.
3254 Simple PC relative relocation.
3257 TOC relative relocation. The value in the instruction in
3258 the input file is the offset from the input file TOC to
3259 the desired location. We want the offset from the final
3260 TOC to the desired location. We have:
3265 so we must change insn by on - in.
3268 GL linkage relocation. The value of this relocation
3269 is the address of the entry in the TOC section.
3272 Local object TOC address. I can't figure out the
3273 difference between this and case R_GL.
3276 TOC relative relocation. A TOC relative load instruction
3277 which may be changed to a load address instruction.
3278 FIXME: We don't currently implement this optimization.
3281 TOC relative relocation. This is a TOC relative load
3282 address instruction which may be changed to a load
3283 instruction. FIXME: I don't know if this is the correct
3287 Absolute branch. We don't want to mess with the lower
3288 two bits of the instruction.
3291 The PowerPC ABI defines this as an absolute call which
3292 may be modified to become a relative call. The PowerOpen
3293 ABI does not define this relocation type.
3296 Absolute branch which may be modified to become a
3300 The PowerPC ABI defines this as an absolute branch to a

3307 fixed address which may be modified to a relative branch.
