[PATCH] D106795: [Analysis] Fix getOrderedReductionCost to call target's getArithmeticInstrCost implementation

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/BasicTTIImpl.h:2093
     InstructionCost ExtractCost =
         getScalarizationOverhead(VTy, /*Insert=*/false, /*Extract=*/true);
+    InstructionCost ArithCost = thisT()->getArithmeticInstrCost(
----------------
Just to be clear - this getScalarizationOverhead call isn't replaced by a target version, its just a base class wrapper that calls the target's DemandedElts variant of getScalarizationOverhead
