[AArch64] Long branch veneer support far symbol defined by --defsym
2015-08-11 Jiong Wang <jiong.wang@arm.com>
bfd/
* bfd/elfnn-aarch64.c (aarch64_type_of_stub): New parameter "sym_sec".
Loose the check for symbol from ABS section.
(elfNN_aarch64_size_stubs): Pass sym_sec.
ld/testsuite/
* ld-aarch64/farcall-b-defsym.s: New test.
* ld-aarch64/farcall-bl-defsym.s: Likewise.
* ld-aarch64/farcall-b-defsym.d: New expectation.
* ld-aarch64/farcall-bl-defsym.d: Likewise.
