[AArch64] Fix predicate and constraint mismatch in logical atomic operations
2014-11-04 Michael Collison <michael.collison@linaro.org>
* config/aarch64/iterators.md (lconst_atomic): New mode attribute
to support constraints for CONST_INT in atomic operations.
* config/aarch64/atomics.md
(atomic_<atomic_optab><mode>): Use lconst_atomic constraint.
(atomic_nand<mode>): Likewise.
(atomic_fetch_<atomic_optab><mode>): Likewise.
(atomic_fetch_nand<mode>): Likewise.
(atomic_<atomic_optab>_fetch<mode>): Likewise.
(atomic_nand_fetch<mode>): Likewise.
