1194 /* XCOFF archive support. The original version of this code was by
1195 Damon A. Permezel. It was enhanced to permit cross support, and
1196 writing archive files, by Ian Lance Taylor, Cygnus Support.
1198 XCOFF uses its own archive format. Everything is hooked together
1199 with file offset links, so it is possible to rapidly update an
1200 archive in place. Of course, we don't do that. An XCOFF archive
1201 has a real file header, not just an ARMAG string. The structure of
1202 the file header and of each archive header appear below.
1204 An XCOFF archive also has a member table, which is a list of
1205 elements in the archive (you can get that by looking through the
1206 linked list, but you have to read a lot more of the file). The
1207 member table has a normal archive header with an empty name. It is
1208 normally (and perhaps must be) the second to last entry in the
1209 archive. The member table data is almost printable ASCII. It
1210 starts with a 12 character decimal string which is the number of
1211 entries in the table. For each entry it has a 12 character decimal
1212 string which is the offset in the archive of that member. These
1213 entries are followed by a series of null terminated strings which
1214 are the member names for each entry.
1216 Finally, an XCOFF archive has a global symbol table, which is what
1217 we call the armap. The global symbol table has a normal archive
1218 header with an empty name. It is normally (and perhaps must be)
1219 the last entry in the archive. The contents start with a four byte
1220 binary number which is the number of entries. This is followed by
1221 a that many four byte binary numbers; each is the file offset of an
1222 entry in the archive. These numbers are followed by a series of
1223 null terminated strings, which are symbol names.
1225 AIX 4.3 introduced a new archive format which can handle larger
1226 files and also 32- and 64-bit objects in the same archive. The
1227 things said above remain true except that there is now more than

3246 relative branches which use half of the difference
3247 between the symbol and the program counter. I can't
3248 quite figure out when this is useful. These relocs are
3249 not defined by the PowerOpen ABI.
3254 Simple positive relocation.
3257 Simple negative relocation.
3260 Simple PC relative relocation.
3263 TOC relative relocation. The value in the instruction in
3264 the input file is the offset from the input file TOC to
3265 the desired location. We want the offset from the final
3266 TOC to the desired location. We have:
3271 so we must change insn by on - in.
3274 GL linkage relocation. The value of this relocation
3275 is the address of the entry in the TOC section.
3278 Local object TOC address. I can't figure out the
3279 difference between this and case R_GL.
3282 TOC relative relocation. A TOC relative load instruction
3283 which may be changed to a load address instruction.
3284 FIXME: We don't currently implement this optimization.
3287 TOC relative relocation. This is a TOC relative load
3288 address instruction which may be changed to a load
3289 instruction. FIXME: I don't know if this is the correct
3293 Absolute branch. We don't want to mess with the lower
3294 two bits of the instruction.
3297 The PowerPC ABI defines this as an absolute call which
3298 may be modified to become a relative call. The PowerOpen
3299 ABI does not define this relocation type.
3302 Absolute branch which may be modified to become a
