Baptiste Saleil	5cbcf5677b	[PowerPC] Rename the vector pair intrinsics and builtins to replace the _mma_ prefix by _vsx_ ... On PPC, the vector pair instructions are independent from MMA. This patch renames the vector pair LLVM intrinsics and Clang builtins to replace the _mma_ prefix by _vsx_ in their names. We also move the vector pair type/intrinsic/builtin tests to their own files. Differential Revision: https://reviews.llvm.org/D91974	2020-12-17 13:19:27 -05:00
Baptiste Saleil	e737a423ce	[PowerPC] Fix for excessive ACC copies due to PHI nodes ... When using accumulators in loops, they are passed around in PHI nodes of unprimed accumulators, causing the generation of additional prime/unprime instructions. This patch detects these cases and changes these PHI nodes to primed accumulator PHI nodes. We also add IR and MIR test cases for several PHI node cases.
