@llvm/pr-subscribers-llvm-transforms Author: Elvis Wang (ElvisWang123) ChangesThis patch reverse the order of instruction cost calculation for VPRecipes in VPBasicBlock to enable bottom up pattern match. Note that after this patch, the VPlan cost model printing will in the reverse order (bottom up). Full diff: https://github.com/llvm/llvm-project/pull/113902.diff 2 Files Affected:
