◆ get() [1/2]

Value * VPTransformState::get ( VPValue *  Def,
const VPIteration &  Instance 
)

Get the generated Value for a given VPValue and given Part and Lane.

Definition at line 227 of file VPlan.cpp.

References assert(), Builder, llvm::IRBuilderBase::CreateExtractElement(), Data, llvm::tgtok::Def, hasScalarValue(), hasVectorValue(), Instance, llvm::VPTransformState::DataState::PerPartOutput, llvm::VPTransformState::DataState::PerPartScalars, and VF.

◆ get() [2/2]

Value * VPTransformState::get ( VPValue *  Def,
unsigned  Part 
)

Get the generated Value for a given VPValue and a given Part.

Note that as some Defs are still created by ILV and managed in its ValueMap, this method will delegate the call to ILV in such cases in order to provide callers a consistent API.
