This follows up Ulrich Weigand's work in PPCInstrInfo.td and PPCInstr64Bit.td by doing the corresponding work for most of the Altivec patterns. I have not been able to do anything for the following classes of instructions: (1) Vector logicals. These don't have corresponding intrinsics and don't have a single obvious vector type. So far as I can tell I need to leave these as VRRC. Affected instructions are: VAND, VANDC, VNOR, VOR, VXOR, V_SET0. (2) Instructions that make use of vector shuffle. The selection code promotes all shuffles to v16i8, so any pattern that matches on a shuffle is constrained. I haven't found any way to make the patterns match on their natural types, so I plan to leave these as VRRC. Affected instructions are: VMRG*, VSPLTB, VSPLTH, VSPLTW, VPKUHUM, VPKUWUM. No change in behavior is anticipated. llvm-svn: 178277 |
