From cd9782e8fd31f32bb976b676249eeefec916c956 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Fri, 21 Oct 1994 23:43:29 +0000 Subject: [PATCH] * targets.c (BFD_JUMP_TABLE_ARCHIVE): Add case for _construct_extended_name_table. (bfd_target): Add _bfd_construct_extended_name_table. * archive.c (_bfd_archive_bsd_construct_extended_name_table): New function. (_bfd_archive_coff_construct_extended_name_table): New function. (_bfd_construct_extended_name_table): Renamed by adding a leading underscore, and made externally visible. Added trailing_slash argument, and used it instead of elf_style. Changed type of tablen to bfd_size_type *. (_bfd_write_archive_contents): Use BFD_SEND to call construct_extended_name_table. Use the returned name. * libbfd-in.h (_bfd_construct_extended_name_table): Declare. (_bfd_noarchive_construct_extended_name_table): Define. (_bfd_archive_bsd_construct_extended_name_table): Declare.
