4 | FIXME: Can someone provide a transliteration of this name into ASCII? |
5 | Using the following chars caused a compiler warning on HIUX (so I replaced | |

7 | character set it is. | |

884 | /* XCOFF archive support. The original version of this code was by | |
885 | Damon A. Permezel. It was enhanced to permit cross support, and | |
886 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
887 | ||
888 | XCOFF uses its own archive format. Everything is hooked together | |
889 | with file offset links, so it is possible to rapidly update an | |
890 | archive in place. Of course, we don't do that. An XCOFF archive | |
891 | has a real file header, not just an ARMAG string. The structure of | |
892 | the file header and of each archive header appear below. | |
893 | ||
894 | An XCOFF archive also has a member table, which is a list of | |
895 | elements in the archive (you can get that by looking through the | |
896 | linked list, but you have to read a lot more of the file). The | |
897 | member table has a normal archive header with an empty name. It is | |
898 | normally (and perhaps must be) the second to last entry in the | |
899 | archive. The member table data is almost printable ASCII. It | |
900 | starts with a 12 character decimal string which is the number of | |
901 | entries in the table. For each entry it has a 12 character decimal | |
902 | string which is the offset in the archive of that member. These | |
903 | entries are followed by a series of null terminated strings which | |
904 | are the member names for each entry. | |
905 | ||
906 | Finally, an XCOFF archive has a global symbol table, which is what | |
907 | we call the armap. The global symbol table has a normal archive | |
908 | header with an empty name. It is normally (and perhaps must be) | |
909 | the last entry in the archive. The contents start with a four byte | |
910 | binary number which is the number of entries. This is followed by | |
911 | a that many four byte binary numbers; each is the file offset of an | |
912 | entry in the archive. These numbers are followed by a series of | |
5ea1af0d GK |
913 | null terminated strings, which are symbol names. |
914 | ||
915 | AIX 4.3 introduced a new archive format which can handle larger | |
916 | files and also 32- and 64-bit objects in the same archive. The | |
917 | things said above remain true except that there is now more than | |
918 | one global symbol table. The one is used to index 32-bit objects, | |
919 | the other for 64-bit objects. | |
920 | ||
921 | The new archives (recognizable by the new ARMAG string) has larger | |
922 | field lengths so that we cannot really share any code. Also we have | |
923 | to take care that we are not generating the new form of archives | |
924 | on AIX 4.2 or earlier systems. */ | |
