| /* 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. */ |
