1067/* XCOFF archive support. The original version of this code was by
1068 Damon A. Permezel. It was enhanced to permit cross support, and
1069 writing archive files, by Ian Lance Taylor, Cygnus Support.
1070
1071 XCOFF uses its own archive format. Everything is hooked together
1072 with file offset links, so it is possible to rapidly update an
1073 archive in place. Of course, we don't do that. An XCOFF archive
1074 has a real file header, not just an ARMAG string. The structure of
1075 the file header and of each archive header appear below.
1076
1077 An XCOFF archive also has a member table, which is a list of
1078 elements in the archive (you can get that by looking through the
1079 linked list, but you have to read a lot more of the file). The
1080 member table has a normal archive header with an empty name. It is
1081 normally (and perhaps must be) the second to last entry in the
1082 archive. The member table data is almost printable ASCII. It
1083 starts with a 12 character decimal string which is the number of
1084 entries in the table. For each entry it has a 12 character decimal
1085 string which is the offset in the archive of that member. These
1086 entries are followed by a series of null terminated strings which
1087 are the member names for each entry.
1088
1089 Finally, an XCOFF archive has a global symbol table, which is what
1090 we call the armap. The global symbol table has a normal archive
1091 header with an empty name. It is normally (and perhaps must be)
1092 the last entry in the archive. The contents start with a four byte
1093 binary number which is the number of entries. This is followed by
1094 a that many four byte binary numbers; each is the file offset of an
1095 entry in the archive. These numbers are followed by a series of
5ea1af0d
GK		 1096 null terminated strings, which are symbol names.
1097
1098 AIX 4.3 introduced a new archive format which can handle larger
1099 files and also 32- and 64-bit objects in the same archive. The
1100 things said above remain true except that there is now more than
1101 one global symbol table. The one is used to index 32-bit objects,
1102 the other for 64-bit objects.
1103
1104 The new archives (recognizable by the new ARMAG string) has larger
1105 field lengths so that we cannot really share any code. Also we have
1106 to take care that we are not generating the new form of archives
1107 on AIX 4.2 or earlier systems. */
