Hi Jiong,

2015-05-19  Jiong Wang  <jiong.wang@arm.com>

bfd/
   * elfnn-aarch64.c (elfNN_aarch64_howto_table): Set overflow type to
   complain_overflow_unsigned for BFD_RELOC_AARCH64_TLSLE_ADD_LO12.
   * elfxx-aarch64.c (_bfd_aarch64_elf_resolve_relocation): Don't use
   PGOFF for BFD_RELOC_AARCH64_TLSLE_ADD_LO12, that will mask off all
   potential high overflowed bits.

ld/testsuite/
   * ld-aarch64/tprel_add_lo12_overflow.s: New testcase.
   * ld-aarch64/tprel_add_lo12_overflow.d: Nex expectation file.
   * ld-aarch64/aarch64-elf.exp: Run new testcase.


Approved - please apply.

Cheers
  Nick
