Strip global symbol defined in discarded section When a global symbol is defined in COMDAT group, we shouldn't leave an undefined symbol in symbol table when the symbol section is discarded unless there is a reference to the symbol outside of COMDAT group. bfd/ PR ld/17550 * elf-bfd.h (elf_link_hash_entry): Update comments for indx, documenting that indx == -3 if symbol is defined in a discarded section. * elflink.c (elf_link_add_object_symbols): Set indx to -3 if symbol is defined in a discarded section. (elf_link_output_extsym): Strip a global symbol defined in a discarded section. ld/ PR ld/17550 * testsuite/ld-elf/pr17550-1.s: New file. * testsuite/ld-elf/pr17550-2.s: Likewise. * testsuite/ld-elf/pr17550-3.s: Likewise. * testsuite/ld-elf/pr17550-4.s: Likewise. * testsuite/ld-elf/pr17550a.d: Likewise. * testsuite/ld-elf/pr17550b.d: Likewise. * testsuite/ld-elf/pr17550c.d: Likewise. * testsuite/ld-elf/pr17550d.d: Likewise. 2016-05-07 00:46:34 +08:00			`#source: pr17550-1.s`
