3 | FIXME: Can someone provide a transliteration of this name into ASCII? | |
4 | Using the following chars caused a compiler warning on HIUX (so I replaced | |
5 | them with octal escapes), and isn't useful without an understanding of what | |
6 | character set it is. | |

564 | /* XCOFF archive support. The original version of this code was by | |
565 | Damon A. Permezel. It was enhanced to permit cross support, and | |
566 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
567 | ||
568 | XCOFF uses its own archive format. Everything is hooked together | |
569 | with file offset links, so it is possible to rapidly update an | |
570 | archive in place. Of course, we don't do that. An XCOFF archive | |
571 | has a real file header, not just an ARMAG string. The structure of | |
572 | the file header and of each archive header appear below. | |
573 | ||
574 | An XCOFF archive also has a member table, which is a list of | |
575 | elements in the archive (you can get that by looking through the | |
576 | linked list, but you have to read a lot more of the file). The | |
577 | member table has a normal archive header with an empty name. It is | |
578 | normally (and perhaps must be) the second to last entry in the | |
579 | archive. The member table data is almost printable ASCII. It | |
580 | starts with a 12 character decimal string which is the number of | |
581 | entries in the table. For each entry it has a 12 character decimal | |
582 | string which is the offset in the archive of that member. These | |
583 | entries are followed by a series of null terminated strings which | |
584 | are the member names for each entry. | |
585 | ||
586 | Finally, an XCOFF archive has a global symbol table, which is what | |
587 | we call the armap. The global symbol table has a normal archive | |
588 | header with an empty name. It is normally (and perhaps must be) | |
589 | the last entry in the archive. The contents start with a four byte | |
590 | binary number which is the number of entries. This is followed by | |
591 | a that many four byte binary numbers; each is the file offset of an | |
592 | entry in the archive. These numbers are followed by a series of | |
593 | null terminated strings, which are symbol names. */ | |
