--- Comment #2 from Michael Meissner <meissner at gcc dot gnu.org> --- Author: meissner Date: Fri May 26 01:52:24 2017 New Revision: 248480 URL: https://gcc.gnu.org/viewcvs?rev=248480&root=gcc&view=rev Log: [gcc] 2017-05-25 Michael Meissner <meiss...@linux.vnet.ibm.com> Backport from trunk 2017-05-18 Michael Meissner <meiss...@linux.vnet.ibm.com> PR target/80510 * config/rs6000/predicates.md (simple_offsettable_mem_operand): New predicate. * config/rs6000/rs6000.md (ALTIVEC_DFORM): New iterator. (define_peephole2 for Altivec d-form load): Add peepholes to catch cases where the register allocator uses a move and an offsettable memory operation to/from a FPR register on ISA 2.06/2.07. (define_peephole2 for Altivec d-form store): Likewise.

(mov<mode>_hardfloat): Split into separate movsf and movsd pieces. For movsf, order stores so the VSX stores occur before the GPR store which encourages the register allocator to use a traditional FPR instead of a GPR. For movsd, order the stores so that the GPR store comes before the VSX stores to allow the power6 to work. This is due to the power6 not having a 32-bit integer store instruction from a FPR. (movsf_hardfloat): Likewise. (movsd_hardfloat): Likewise.
