Added a predicate for this. * Prefetch with immediate offset - in the range -256 to 255 (Gets generated only when we have a negative offset. Generates prfum instruction). Added a predicate for this. * Prefetch with register offset. (modified for printing the locality) This patch has been already discussed on https://gcc.gnu.org/ml/gcc-patches/2014-02/msg01644.html "make -k check" passes. Ok for trunk? Changelog 2014-07-04 Ganesh Gopalasubramanian <ganesh.gopalasubraman...@amd.com> * config/aarch64/aarch64.md (define_insn "*prefetch") (define_insn "prefetch"): New * config/aarch64/predicates.md (aarch64_prefetch_pimm) (aarch64_prefetch_unscaled): New. * config/arm/types.md (define_attr "type"): Add prefetch. Regards Ganesh
