1193 /* XCOFF archive support. The original version of this code was by
1194 Damon A. Permezel. It was enhanced to permit cross support, and
1195 writing archive files, by Ian Lance Taylor, Cygnus Support.
1197 XCOFF uses its own archive format. Everything is hooked together
1198 with file offset links, so it is possible to rapidly update an
1199 archive in place. Of course, we don't do that. An XCOFF archive
1200 has a real file header, not just an ARMAG string. The structure of
1201 the file header and of each archive header appear below.
1203 An XCOFF archive also has a member table, which is a list of
1204 elements in the archive (you can get that by looking through the
1205 linked list, but you have to read a lot more of the file). The
1206 member table has a normal archive header with an empty name. It is
1207 normally (and perhaps must be) the second to last entry in the
1208 archive. The member table data is almost printable ASCII. It
1209 starts with a 12 character decimal string which is the number of
1210 entries in the table. For each entry it has a 12 character decimal
1211 string which is the offset in the archive of that member. These
1212 entries are followed by a series of null terminated strings which
1213 are the member names for each entry.
1215 Finally, an XCOFF archive has a global symbol table, which is what
1216 we call the armap. The global symbol table has a normal archive
1217 header with an empty name. It is normally (and perhaps must be)
1218 the last entry in the archive. The contents start with a four byte
1219 binary number which is the number of entries. This is followed by
1220 a that many four byte binary numbers; each is the file offset of an
1221 entry in the archive. These numbers are followed by a series of
1222 null terminated strings, which are symbol names.
1224 AIX 4.3 introduced a new archive format which can handle larger
1225 files and also 32- and 64-bit objects in the same archive. The
1226 things said above remain true except that there is now more than
1227 one global symbol table. The one is used to index 32-bit objects,
1228 the other for 64-bit objects.
1230 The new archives (recognizable by the new ARMAG string) has larger
1231 field lengths so that we cannot really share any code. Also we have
1232 to take care that we are not generating the new form of archives

3256 quite figure out when this is useful. These relocs are

3262 Simple positive relocation.
3265 Simple negative relocation.
3268 Simple PC relative relocation.
3271 TOC relative relocation. The value in the instruction in

3273 the desired location. We want the offset from the final
3274 TOC to the desired location. We have:
3279 so we must change insn by on - in.
3282 GL linkage relocation. The value of this relocation
3283 is the address of the entry in the TOC section.
3286 Local object TOC address. I can't figure out the
3287 difference between this and case R_GL.
3290 TOC relative relocation. A TOC relative load instruction
3291 which may be changed to a load address instruction.
3292 FIXME: We don't currently implement this optimization.
3295 TOC relative relocation. This is a TOC relative load
3296 address instruction which may be changed to a load
3297 instruction. FIXME: I don't know if this is the correct
3301 Absolute branch. We don't want to mess with the lower
3302 two bits of the instruction.
3305 The PowerPC ABI defines this as an absolute call which
3306 may be modified to become a relative call. The PowerOpen
3307 ABI does not define this relocation type.
3310 Absolute branch which may be modified to become a
