We attempt to insert the new recipe in the same place, but this is wrong because createBlockInMask may have generated new recipes that VPReductionRecipe now depends upon. I have changed the insertion code to append the recipe to the VPBasicBlock instead. Added a new RUN with tail-folding enabled to the existing test: Transforms/LoopVectorize/AArch64/scalable-strict-fadd.ll Differential Revision: https://reviews.llvm.org/D129550 Reported by: yuri PR: 264834 MFC after: 3 days contrib/llvm-project/llvm/lib/Transforms/Vectorize/LoopVectorize.cpp | 4 += ++- 1 file changed, 3 insertions(+), 1 deletion(-) --=20 You are receiving this mail because: You are the assignee for the bug.=
