Function Documentation

cloneForLane()

VPValue * cloneForLane ( VPlan & Plan, VPBuilder & Builder, Type * IdxTy, VPRecipeWithIRFlags * DefR, VPLane Lane, const DenseMap< VPValue *, SmallVector< VPValue * > > & Def2LaneDefs )

static

Create a single-scalar clone of DefR (must be a VPReplicateRecipe or VPInstruction) for lane Lane.

Use Def2LaneDefs to look up scalar definitions for operands of \DefR.
