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