Luke Lau	f0d5104c94	[VPlan] Handle some VPInstructions in may{Read,Write}FromMemory (#120058 ) This just copies the same conservative definition from mayWriteToMemory, and enables more VPInstructions to be hoisted out in LICM. I think this should give more accurate costs, and I was able to build llvm-test-suite without the legacy-vplan cost model assertion going off.	2025-01-08 15:17:26 +08:00
Paul Walker	38fffa630e	[LLVM][IR] Use splat syntax when printing Constant[Data]Vector. (#112548 )	2024-11-06 11:53:33 +00:00
Florian Hahn	a861ed411a	[VPlan] Add initial loop-invariant code motion transform. (#107894 ) Add initial transform to move out loop-invariant recipes. This also helps to fix a divergence between legacy and VPlan-based cost model due to legacy using ScalarEvolution::isLoopInvariant in some cases. Fixes https://github.com/llvm/llvm-project/issues/107501. PR: https://github.com/llvm/llvm-project/pull/107894	2024-09-20 11:22:03 +01:00
Florian Hahn	34777c238b	[VPlan] Don't mark VPBlendRecipe as phi-like. VPBlendRecipes don't get lowered to phis and usually do not appear at the beginning of blocks, due to their masks appearing before them. This effectively relaxes an over-eager verifier message.
