| 931 | /* XCOFF archive support. The original version of this code was by |
| 932 | Damon A. Permezel. It was enhanced to permit cross support, and |
| 933 | writing archive files, by Ian Lance Taylor, Cygnus Support. |
| 934 | |
| 935 | XCOFF uses its own archive format. Everything is hooked together |
| 936 | with file offset links, so it is possible to rapidly update an |
| 937 | archive in place. Of course, we don't do that. An XCOFF archive |
| 938 | has a real file header, not just an ARMAG string. The structure of |
| 939 | the file header and of each archive header appear below. |
| 940 | |
| 941 | An XCOFF archive also has a member table, which is a list of |
| 942 | elements in the archive (you can get that by looking through the |
| 943 | linked list, but you have to read a lot more of the file). The |
| 944 | member table has a normal archive header with an empty name. It is |
| 945 | normally (and perhaps must be) the second to last entry in the |
| 946 | archive. The member table data is almost printable ASCII. It |
| 947 | starts with a 12 character decimal string which is the number of |
| 948 | entries in the table. For each entry it has a 12 character decimal |
| 949 | string which is the offset in the archive of that member. These |
| 950 | entries are followed by a series of null terminated strings which |
| 951 | are the member names for each entry. |
| 952 | |
| 953 | Finally, an XCOFF archive has a global symbol table, which is what |
| 954 | we call the armap. The global symbol table has a normal archive |
| 955 | header with an empty name. It is normally (and perhaps must be) |
| 956 | the last entry in the archive. The contents start with a four byte |
| 957 | binary number which is the number of entries. This is followed by |
| 958 | a that many four byte binary numbers; each is the file offset of an |
| 959 | entry in the archive. These numbers are followed by a series of |
| 960 | null terminated strings, which are symbol names. |
| 961 | |
| 962 | AIX 4.3 introduced a new archive format which can handle larger |
| 963 | files and also 32- and 64-bit objects in the same archive. The |
| 964 | things said above remain true except that there is now more than |
| 965 | one global symbol table. The one is used to index 32-bit objects, |
| 966 | the other for 64-bit objects. |
| 967 | |
| 968 | The new archives (recognizable by the new ARMAG string) has larger |
| 969 | field lengths so that we cannot really share any code. Also we have |
| 970 | to take care that we are not generating the new form of archives |
| 971 | on AIX 4.2 or earlier systems. */ |
