doesn't always mean you need to define a function symbol on plt code. If all references are in read-write sections, then using dynamic relocs is OK. bfd/ * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Clear pointer_equality_needed when !readonly_dynrelocs. * elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise. ld/testsuite/ * ld-powerpc/ambiguousv1.d: Match symbol table too. * ld-powerpc/ambiguousv2.d: Likewise. * ld-powerpc/ambiguousv1b.d: New. * ld-powerpc/ambiguousv2b.d: New. * ld-powerpc/powerpc.exp: Run new tests.
