1066/* XCOFF archive support. The original version of this code was by
1067 Damon A. Permezel. It was enhanced to permit cross support, and
1068 writing archive files, by Ian Lance Taylor, Cygnus Support.
1069
1070 XCOFF uses its own archive format. Everything is hooked together
1071 with file offset links, so it is possible to rapidly update an
1072 archive in place. Of course, we don't do that. An XCOFF archive
1073 has a real file header, not just an ARMAG string. The structure of
1074 the file header and of each archive header appear below.
1075
1076 An XCOFF archive also has a member table, which is a list of
1077 elements in the archive (you can get that by looking through the
1078 linked list, but you have to read a lot more of the file). The
1079 member table has a normal archive header with an empty name. It is
1080 normally (and perhaps must be) the second to last entry in the
1081 archive. The member table data is almost printable ASCII. It
1082 starts with a 12 character decimal string which is the number of
1083 entries in the table. For each entry it has a 12 character decimal
1084 string which is the offset in the archive of that member. These
1085 entries are followed by a series of null terminated strings which
1086 are the member names for each entry.
1087
1088 Finally, an XCOFF archive has a global symbol table, which is what
1089 we call the armap. The global symbol table has a normal archive
1090 header with an empty name. It is normally (and perhaps must be)
1091 the last entry in the archive. The contents start with a four byte
1092 binary number which is the number of entries. This is followed by
1093 a that many four byte binary numbers; each is the file offset of an
1094 entry in the archive. These numbers are followed by a series of
5ea1af0d
GK		 1095 null terminated strings, which are symbol names.
1096
1097 AIX 4.3 introduced a new archive format which can handle larger
1098 files and also 32- and 64-bit objects in the same archive. The
1099 things said above remain true except that there is now more than
1100 one global symbol table. The one is used to index 32-bit objects,
1101 the other for 64-bit objects.
1102
1103 The new archives (recognizable by the new ARMAG string) has larger
1104 field lengths so that we cannot really share any code. Also we have
1105 to take care that we are not generating the new form of archives
1106 on AIX 4.2 or earlier systems. */
