1175 /* XCOFF archive support. The original version of this code was by
1176 Damon A. Permezel. It was enhanced to permit cross support, and
1177 writing archive files, by Ian Lance Taylor, Cygnus Support.
1179 XCOFF uses its own archive format. Everything is hooked together
1180 with file offset links, so it is possible to rapidly update an
1181 archive in place. Of course, we don't do that. An XCOFF archive
1182 has a real file header, not just an ARMAG string. The structure of
1183 the file header and of each archive header appear below.
1185 An XCOFF archive also has a member table, which is a list of
1186 elements in the archive (you can get that by looking through the
1187 linked list, but you have to read a lot more of the file). The
1188 member table has a normal archive header with an empty name. It is
1189 normally (and perhaps must be) the second to last entry in the
1190 archive. The member table data is almost printable ASCII. It
1191 starts with a 12 character decimal string which is the number of
1192 entries in the table. For each entry it has a 12 character decimal
1193 string which is the offset in the archive of that member. These
1194 entries are followed by a series of null terminated strings which
1195 are the member names for each entry.
1197 Finally, an XCOFF archive has a global symbol table, which is what
1198 we call the armap. The global symbol table has a normal archive
1199 header with an empty name. It is normally (and perhaps must be)
1200 the last entry in the archive. The contents start with a four byte
1201 binary number which is the number of entries. This is followed by
1202 a that many four byte binary numbers; each is the file offset of an
1203 entry in the archive. These numbers are followed by a series of
1204 null terminated strings, which are symbol names.
1206 AIX 4.3 introduced a new archive format which can handle larger
1207 files and also 32- and 64-bit objects in the same archive. The
1208 things said above remain true except that there is now more than
1209 one global symbol table. The one is used to index 32-bit objects,
1210 the other for 64-bit objects.
1212 The new archives (recognizable by the new ARMAG string) has larger
1213 field lengths so that we cannot really share any code. Also we have
1214 to take care that we are not generating the new form of archives
1215 on AIX 4.2 or earlier systems. */
