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.
