2015-04-24 Jiong. Wang <jiong.wang@arm.com>
bfd/
* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Reject
PC-relative relocation for external symbol.
ld/testsuite/
* ld-aarch64/pcrel.s: New testcase.
* ld-aarch64/pcrel_pic_defiend_local.d: New expect file.
* ld-aarch64/pcrel_pic_undefined.d: Ditto.
* ld-aarch64/aarch64-elf.exp: Run them.
