  "message": "[SLP][X86]Vectorize alternate fadd/fsub fused with fmul (fmaddsub/fmsubadd)\n\nExtend getAltInstrCost, so X86 can estimate the fmaddsub/fmsubadd forms\nwhen every lane fuses with a one-use fmul. For a tree with such a node,\ncount the fused node together with the fmul and ignore\nsplat/free-extract overhead in the VF\u003d2 instruction-count check,\nmatching the machine-level fma count in the scalar code.\n\nAssisted-by: Cursor\n\nReviewers: RKSimon, bababuck\n\nPull Request: https://github.com/llvm/llvm-project/pull/229268",
