...he independent evaluation of multiple vectorization scenarios in the future. This seems to fit into that category. > Add support for SLP style vectorization to Vplan > ------------------------------------------------------------------------ > Introduce 2 new recipes VPSLPMemoryRecipe and VPSLPInstructionRecipe. We introduced VPInstructions to model masking in patch D38676. They are necessary to properly model the def-use/use-def chains in the VPlan representation, and we believe you will need to represent def-use/use-def chains for newly inserted operations, shuffles, and inserts/extracts. As such, VP...

...rization for some operations. Initially we could only consider SLP-style vectorization if it can be used for all instructions. Add support for SLP style vectorization to Vplan ------------------------------------------------------------------------ Introduce 2 new recipes VPSLPMemoryRecipe and VPSLPInstructionRecipe. Both generate code to produce a single compound value and we add those recipes for the instruction in lane 0 of the compound value. We do not add any recipes for instructions in other lanes. The SLP vectorizer in LLVM also implements code generation for similar cases. In the long term it mi...
