Summary: In big archive , there is 32bit global symbol table and 64 bit global symbol table. llvm-ar only support 32bit global symbol table this moment, we need to support the 64 bit global symbol table. https://www.ibm.com/docs/en/aix/7.2?topic=formats-ar-file-format-big Global Symbol Tables Immediately following the member table, the archive file contains two global symbol tables. The first global symbol table locates 32-bit file members that define global symbols; the second global symbol table does the same for 64-bit file members. If the archive has no 32-bit or 64-bit file members, the respective global symbol table is omitted. The strip command can be used to delete one or both global symbol tables from the archive. The fl_gstoff field in the fixed-length header contains the offset to the 32-bit global symbol table, and the fl_gst64off contains the offset to the 64-bit global symbol table.
