1197/* XCOFF archive support. The original version of this code was by
1198 Damon A. Permezel. It was enhanced to permit cross support, and
1199 writing archive files, by Ian Lance Taylor, Cygnus Support.
1200
1201 XCOFF uses its own archive format. Everything is hooked together
1202 with file offset links, so it is possible to rapidly update an
1203 archive in place. Of course, we don't do that. An XCOFF archive
1204 has a real file header, not just an ARMAG string. The structure of
1205 the file header and of each archive header appear below.
1206
1207 An XCOFF archive also has a member table, which is a list of
1208 elements in the archive (you can get that by looking through the
1209 linked list, but you have to read a lot more of the file). The
1210 member table has a normal archive header with an empty name. It is
1211 normally (and perhaps must be) the second to last entry in the
1212 archive. The member table data is almost printable ASCII. It
1213 starts with a 12 character decimal string which is the number of
1214 entries in the table. For each entry it has a 12 character decimal
1215 string which is the offset in the archive of that member. These
1216 entries are followed by a series of null terminated strings which
1217 are the member names for each entry.
1218
1219 Finally, an XCOFF archive has a global symbol table, which is what
1220 we call the armap. The global symbol table has a normal archive
1221 header with an empty name. It is normally (and perhaps must be)
1222 the last entry in the archive. The contents start with a four byte
1223 binary number which is the number of entries. This is followed by
1224 a that many four byte binary numbers; each is the file offset of an
1225 entry in the archive. These numbers are followed by a series of
5ea1af0d
GK		 1226 null terminated strings, which are symbol names.
1227
1228 AIX 4.3 introduced a new archive format which can handle larger
1229 files and also 32- and 64-bit objects in the same archive. The
1230 things said above remain true except that there is now more than
1231 one global symbol table. The one is used to index 32-bit objects,
1232 the other for 64-bit objects.
1233
1234 The new archives (recognizable by the new ARMAG string) has larger
1235 field lengths so that we cannot really share any code. Also we have
1236 to take care that we are not generating the new form of archives
1237 on AIX 4.2 or earlier systems. */
