[AArch64] Use atomic load-operate instructions for update-fetch patterns.
2015-09-22 Matthew Wahab <matthew.wahab@arm.com>
* config/aarch64/aarch64-protos.h (aarch64_gen_atomic_ldop):
Adjust declaration.
* config/aarch64/aarch64.c (aarch64_emit_bic): New.
(aarch64_gen_atomic_ldop): Adjust comment. Add parameter
out_result. Update to support update-fetch operations.
* config/aarch64/atomics.md (aarch64_atomic_exchange<mode>_lse):
Adjust for change to aarch64_gen_atomic_ldop.
(aarch64_atomic_<atomic_optab><mode>_lse): Likewise.
(aarch64_atomic_fetch_<atomic_optab><mode>_lse): Likewise.
(atomic_<atomic_optab>_fetch<mode>): Change to an expander.
(aarch64_atomic_<atomic_optab>_fetch<mode>): New.
(aarch64_atomic_<atomic_optab>_fetch<mode>_lse): New.
