1071 /* XCOFF archive support. The original version of this code was by
1072 Damon A. Permezel. It was enhanced to permit cross support, and
1073 writing archive files, by Ian Lance Taylor, Cygnus Support.
1075 XCOFF uses its own archive format. Everything is hooked together
1076 with file offset links, so it is possible to rapidly update an
1077 archive in place. Of course, we don't do that. An XCOFF archive
1078 has a real file header, not just an ARMAG string. The structure of
1079 the file header and of each archive header appear below.
1081 An XCOFF archive also has a member table, which is a list of
1082 elements in the archive (you can get that by looking through the
1083 linked list, but you have to read a lot more of the file). The
1084 member table has a normal archive header with an empty name. It is
1085 normally (and perhaps must be) the second to last entry in the
1086 archive. The member table data is almost printable ASCII. It
1087 starts with a 12 character decimal string which is the number of
1088 entries in the table. For each entry it has a 12 character decimal
1089 string which is the offset in the archive of that member. These
1090 entries are followed by a series of null terminated strings which
1091 are the member names for each entry.
1093 Finally, an XCOFF archive has a global symbol table, which is what
1094 we call the armap. The global symbol table has a normal archive
1095 header with an empty name. It is normally (and perhaps must be)
1096 the last entry in the archive. The contents start with a four byte
1097 binary number which is the number of entries. This is followed by
1098 a that many four byte binary numbers; each is the file offset of an
1099 entry in the archive. These numbers are followed by a series of
1100 null terminated strings, which are symbol names.
1102 AIX 4.3 introduced a new archive format which can handle larger
1103 files and also 32- and 64-bit objects in the same archive. The
1104 things said above remain true except that there is now more than
1105 one global symbol table. The one is used to index 32-bit objects,
1106 the other for 64-bit objects.
1108 The new archives (recognizable by the new ARMAG string) has larger
1109 field lengths so that we cannot really share any code. Also we have
1110 to take care that we are not generating the new form of archives
1111 on AIX 4.2 or earlier systems. */

3305 difference between this and case R_GL.
3308 TOC relative relocation. A TOC relative load instruction
3309 which may be changed to a load address instruction.
3310 FIXME: We don't currently implement this optimization.

3314 address instruction which may be changed to a load
3315 instruction. FIXME: I don't know if this is the correct
3319 Absolute branch. We don't want to mess with the lower
3320 two bits of the instruction.
3323 The PowerPC ABI defines this as an absolute call which
