1130 /* XCOFF archive support. The original version of this code was by
1131 Damon A. Permezel. It was enhanced to permit cross support, and
1132 writing archive files, by Ian Lance Taylor, Cygnus Support.
1134 XCOFF uses its own archive format. Everything is hooked together
1135 with file offset links, so it is possible to rapidly update an
1136 archive in place. Of course, we don't do that. An XCOFF archive
1137 has a real file header, not just an ARMAG string. The structure of
1138 the file header and of each archive header appear below.
1140 An XCOFF archive also has a member table, which is a list of
1141 elements in the archive (you can get that by looking through the
1142 linked list, but you have to read a lot more of the file). The
1143 member table has a normal archive header with an empty name. It is
1144 normally (and perhaps must be) the second to last entry in the
1145 archive. The member table data is almost printable ASCII. It
1146 starts with a 12 character decimal string which is the number of
1147 entries in the table. For each entry it has a 12 character decimal
1148 string which is the offset in the archive of that member. These
1149 entries are followed by a series of null terminated strings which
1150 are the member names for each entry.
1152 Finally, an XCOFF archive has a global symbol table, which is what
1153 we call the armap. The global symbol table has a normal archive
1154 header with an empty name. It is normally (and perhaps must be)
1155 the last entry in the archive. The contents start with a four byte
1156 binary number which is the number of entries. This is followed by
1157 a that many four byte binary numbers; each is the file offset of an
1158 entry in the archive. These numbers are followed by a series of
1159 null terminated strings, which are symbol names.
1161 AIX 4.3 introduced a new archive format which can handle larger
1162 files and also 32- and 64-bit objects in the same archive. The
1163 things said above remain true except that there is now more than
1164 one global symbol table. The one is used to index 32-bit objects,
1165 the other for 64-bit objects.
1167 The new archives (recognizable by the new ARMAG string) has larger
1168 field lengths so that we cannot really share any code. Also we have
1169 to take care that we are not generating the new form of archives
1170 on AIX 4.2 or earlier systems. */

3253 GL linkage relocation. The value of this relocation
3254 is the address of the entry in the TOC section.

3258 difference between this and case R_GL.
3261 TOC relative relocation. A TOC relative load instruction
3262 which may be changed to a load address instruction.
3263 FIXME: We don't currently implement this optimization.

3267 address instruction which may be changed to a load
3268 instruction. FIXME: I don't know if this is the correct
3272 Absolute branch. We don't want to mess with the lower
3273 two bits of the instruction.
3276 The PowerPC ABI defines this as an absolute call which
