  "message": "[LV] Remove legacy selectVectorizationFactor and assert (NFCI) (#190838)\n\nAlmost all recipes now go through ::computeCost to properly compute\ntheir costs using the VPlan-based cost model. There are currently no\nknown cases where the VPlan-based cost model returns an incorrect cost\nvs the legacy cost model. I check the remaining open issues with reports\nof the assertion triggering and in all cases the VPlan-based cost model\nis more accurate, which is causing the divergence.\n\nThere are still some fall-back paths, mostly via precomputeCosts, but\nthose cannot be easily removed without triggering the assert, as the\nVPlan-based cost model is more accurate for those cases. An example of\nthis is https://github.com/llvm/llvm-project/pull/187056.\n\nFixes https://github.com/llvm/llvm-project/issues/38575. \nFixes https://github.com/llvm/llvm-project/issues/149651. \nFixes https://github.com/llvm/llvm-project/issues/182646. \nFixes https://github.com/llvm/llvm-project/issues/183739. \nFixes https://github.com/llvm/llvm-project/issues/187523.\n\nPR: https://github.com/llvm/llvm-project/pull/190838",
