Generalize scalarization (recently enhanced with D80885) to allow compares as well as binops. Similar to binops, we are avoiding scalarization of a loaded value because that could avoid a register transfer in codegen. This requires 1 extra predicate that I am aware of: we do not want to scalarize the condition value of a vector select. That might also invert a transform that we do in instcombine that prefers a vector condition operand for a vector select. I think this is the final step in solving PR37463: https://bugs.llvm.org/show_bug.cgi?id=37463 Differential Revision: https://reviews.llvm.org/D81661 |
