2015-01-27 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com>
Jiong Wang <jiong.wang@arm.com>
gcc/
* config/aarch64/aarch64.md (tb<optab><mode>1): Clobber CC reg instead of
scratch reg.
(cb<optab><mode>1): Likewise.
* config/aarch64/iterators.md (bcond): New define_code_attr.
gcc/testsuite/
* gcc.dg/long_branch.c: New testcase.
