It updates optimizeInductionsto also introduce new VPScalarIVStepsRecipes if an IV has both vectorand scalar uses.It updates all uses that only need scalar values to use the newlycreated recipe for the scalar steps.This completes untangling of VPWidenIntOrFpInductionRecipecode-generation. Now the recipe *only* creates the widened vectorvalues, as it says on the tin.The code to genereate IR has been moved directly toVPWidenIntOrFpInductionRecipe::execute.Note that the recipe has been updated to hold a reference toScalarEvolution, which is needed to expand the step, until we can placethe corresponding SCEV expansion in the pre-header.Depends on D120827.Reviewed By: AyalDifferential Revision: https://reviews.llvm.org/D120828 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll Sun, 13 Mar 2022 17:15:24 +0000 Florian Hahn <flo@fhahn.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll#da740492 [VPlan] Remove dead header-phi recipes.This patch adds a new transform to remove dead recipes.

The problem is that LV propagates poison-generating flags (`nuw`/`nsw`, `exact`and `inbounds`) in instructions that contribute to the address computation of widen loads/stores that areguarded by a condition. It may happen that when the code is vectorized and the control flow within the loopis linearized, these flags may lead to generating a poison value that is effectively used as the base addressof the widen load/store. The fix drops all the integer poison-generating flags from instructions thatcontribute to the address computation of a widen load/store whose original instruction was in a basic blockthat needed predication and is not predicated after vectorization.Reviewed By: fhahn, spatel, nlopesDifferential Revision: https://reviews.llvm.org/D111846 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll Mon, 22 Nov 2021 10:18:45 +0000 Diego Caballero <diegocaballero@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll#23c2f2e6 [LV] Mark increment of main vector loop induction variable as NUW.This patch marks the induction increment of the main induction variableof the vector loop as NUW when not folding the tail.If the tail is not folded, we know that End - Start >= Step (eitherstatically or through the minimum iteration checks). We also know that bothStart % Step == 0 and End % Step == 0. We exit the vector loop if %IV +%Step == %End. Hence we must exit the loop before %IV + %Step unsignedoverflows and we can mark the induction increment as NUW.This should make SCEV return more precise bounds for the created vectorloops, used by later optimizations, like late unrolling.At the moment quite a few tests still need to be updated, but beforedoing so I'd like to get initial feedback to make sure I am not missinganything.Note that this could probably be further improved by using informationfrom the original IV.Attempt of modeling of the assumption in Alive2:https://alive2.llvm.org/ce/z/H_DL_gPart of a set of fixes required for PR50412.Reviewed By: mkazantsevDifferential Revision: https://reviews.llvm.org/D103255 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll Mon, 07 Jun 2021 08:24:27 +0000 Florian Hahn <flo@fhahn.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/LoopVectorize/single-value-blend-phis.ll#6240f436 Recommit "[LV] Allow tryToCreateWidenRecipe to return a VPValue, use for blends."This reverts the revert commit 437f0bbcd509d0ed71b91ec1f86f48c2f4aae980.It adds a new toVPRecipeResult, which forces VPRecipeOrVPValueTy to beconstructed with a VPRecipeBase *.
