class VPReplicateRecipe

Declaration

class VPReplicateRecipe : public VPRecipeBase, public VPValue { /* full declaration omitted */ };

Description

VPReplicateRecipe replicates a given instruction producing multiple scalar copies of the original scalar type, one per lane, instead of producing a single copy of widened type for all lanes. If the instruction is known to be uniform only one copy, per lane zero, will be generated.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1551

Inherits from: VPRecipeBase, VPValue

Member Variables

private bool IsUniform

Indicator if only a single replica per lane is needed.

private bool IsPredicated

Indicator if the replicas are also predicated.

private bool AlsoPack

Indicator if the scalar values should also be packed into a vector.
