An AArch64ISD::DUP is just a splat, where the known bits for each lane are the same as the input. This teaches that to computeKnownBitsForTargetNode. Problems arise for constants though, as a constant BUILD_VECTOR can be lowered to an AArch64ISD::DUP, which SimplifyDemandedBits would then turn back into a constant BUILD_VECTOR leading to an infinite cycle. This has been prevented by adding a isTargetCanonicalConstantNode node to prevent the conversion back into a BUILD_VECTOR. Differential Revision: https://reviews.llvm.org/D128144 |
