1189/* XCOFF archive support. The original version of this code was by
1190 Damon A. Permezel. It was enhanced to permit cross support, and
1191 writing archive files, by Ian Lance Taylor, Cygnus Support.
1192
1193 XCOFF uses its own archive format. Everything is hooked together
1194 with file offset links, so it is possible to rapidly update an
1195 archive in place. Of course, we don't do that. An XCOFF archive
1196 has a real file header, not just an ARMAG string. The structure of
1197 the file header and of each archive header appear below.
1198
1199 An XCOFF archive also has a member table, which is a list of
1200 elements in the archive (you can get that by looking through the
1201 linked list, but you have to read a lot more of the file). The
1202 member table has a normal archive header with an empty name. It is
1203 normally (and perhaps must be) the second to last entry in the
1204 archive. The member table data is almost printable ASCII. It
1205 starts with a 12 character decimal string which is the number of
1206 entries in the table. For each entry it has a 12 character decimal
1207 string which is the offset in the archive of that member. These
1208 entries are followed by a series of null terminated strings which
1209 are the member names for each entry.
1210
1211 Finally, an XCOFF archive has a global symbol table, which is what
1212 we call the armap. The global symbol table has a normal archive
1213 header with an empty name. It is normally (and perhaps must be)
1214 the last entry in the archive. The contents start with a four byte
1215 binary number which is the number of entries. This is followed by
1216 a that many four byte binary numbers; each is the file offset of an
1217 entry in the archive. These numbers are followed by a series of
5ea1af0d
GK		 1218 null terminated strings, which are symbol names.
1219
1220 AIX 4.3 introduced a new archive format which can handle larger
1221 files and also 32- and 64-bit objects in the same archive. The
1222 things said above remain true except that there is now more than
1223 one global symbol table. The one is used to index 32-bit objects,
1224 the other for 64-bit objects.
1225
1226 The new archives (recognizable by the new ARMAG string) has larger
1227 field lengths so that we cannot really share any code. Also we have
1228 to take care that we are not generating the new form of archives
1229 on AIX 4.2 or earlier systems. */

3277 TOC relative relocation. The value in the instruction in
3278 the input file is the offset from the input file TOC to
3279 the desired location. We want the offset from the final
