static void ComputePTXValueVTs ( const TargetLowering &  TLI, Type *  Ty, SmallVectorImpl< EVT > &  ValueVTs, SmallVectorImpl< uint64_t > *  Offsets = 0, uint64_t  StartingOffset = 0  )

static

ComputePTXValueVTs - For the given Type Ty, returns the set of primitive EVTs that compose it. Unlike ComputeValueVTs, this will break apart vectors into their primitive components. NOTE: This is a band-aid for code that expects ComputeValueVTs to return the same number of types as the Ins/Outs arrays in LowerFormalArguments, LowerCall, and LowerReturn.
