Handle weak alias for PIE with copy reloc When there is a weak symbol with a real definition, the processor independent code will have arranged for us to see the real definition first. We need to copy the needs_copy bit from the real definition and check it when allowing copy reloc in PIE. bfd/ PR ld/17689 * elf64-x86-64.c (elf_x86_64_link_hash_entry): Add needs_copy. Change has_bnd_reloc to bit field. (elf_x86_64_link_hash_newfunc): Initialize needs_copy and has_bnd_reloc to 0. (elf_x86_64_check_relocs): Set has_bnd_reloc to 1 instead of TRUE. (elf_x86_64_adjust_dynamic_symbol): Copy needs_copy from the real definition to a weak symbol. (elf_x86_64_allocate_dynrelocs): Also check needs_copy of a weak symbol for PIE when discarding space for relocs against symbols which turn out to need copy relocs. (elf_x86_64_relocate_section): Also check needs_copy of a weak symbol for PIE with copy reloc. ld/testsuite/ PR ld/17689 * ld-x86-64/pr17689.out: New file. * ld-x86-64/pr17689.rd: Likewise. * ld-x86-64/pr17689a.c: Likewise. * ld-x86-64/pr17689b.S: Likewise. * ld-x86-64/x86-64.exp: Run PR ld/17689 tests. 2014-12-14 15:37:22 +08:00			`#...`
