Use a symbol flag bit to mark linker defined symbols
Trying to use the SEC_LINKER_CREATED section flag to determine whether a symbol is linker defined fails to work on targets like alpha that define special SEC_COMMON sections. These might contain symbols that originated in an object file. include/ * bfdlink.h (struct bfd_link_hash_entry): Comment non_ir_ref. Add linker_def. bfd/ * elflink.c (_bfd_elf_define_linkage_sym): Set linker_def. * linker.c (_bfd_generic_link_add_one_symbol): Clear linker_def for CDEF, DEF, DEFW, COM. ld/ * ldexp.c (exp_fold_tree_1 <etree_provide>): Test linker_def. ld/testsuite/ * ld-powerpc/sdabase.s, * ld-powerpc/sdabase.t, * ld-powerpc/sdabase.d: New test. * ld-powerpc/sdabase2.t, * ld-powerpc/sdabase2.d: New test. * ld-powerpc/powerpc.exp: Run them.
