2003-05-04 H.J. Lu <hjl@gnu.org> * elf32-i386.c (allocate_dynrelocs): Don't allocate dynamic relocation entries for weak undefined symbols with non-default visibility. (elf_i386_relocate_section): Initialize the GOT entries and skip R_386_32/R_386_PC32 for weak undefined symbols with non-default visibility. * elfxx-ia64.c (allocate_fptr): Don't allocate function descriptors for weak undefined symbols with non-default visibility. (allocate_dynrel_entries): Don't allocate relocation entries for symbols resolved to 0. (set_got_entry): Don't install dynamic relocation for weak undefined symbols with non-default visibility. (set_pltoff_entry): Likewise. * elflink.h (elf_fix_symbol_flags): Hide weak undefined symbols with non-default visibility. (elf_link_output_extsym): Don't make weak undefined symbols with non-default visibility dynamic. ld/testsuite/ 2003-05-04 H.J. Lu <hjl@gnu.org> * ld-elfvsb/main.c: Updated. * ld-elfvsb/sh1.c: Likewise.
