For some pc-relative relocations we want to allow them under PIC mode while a normal global symbol defined in the same dynamic object can still bind externally through copy relocation. So, we should not allow pc-relative relocation against such symbol. SYMBOL_REFERENCES_LOCAL should be used and is more accurate than the original individual checks. bfd/ * elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Use SYMBOL_REFERENCES_LOCAL. ld/ * testsuite/ld-aarch64/aarch64-elf.exp: Update test name * testsuite/ld-aarch64/pcrel.s: Add new testcases. * testsuite/ld-aarch64/pcrel_pic_undefined.d: Update the expected warnings. * testsuite/ld-aarch64/pcrel_pic_defined_local.d: Rename ... * testsuite/ld-aarch64/pcrel_pic_defined.d: ... to this. Update expected warnings.
