Function Documentation

SDOperand llvm::PPC::get_VSPLTI_elt	(	SDNode *	N,
		unsigned	ByteSize,
		SelectionDAG &	DAG
	)

get_VSPLTI_elt - If this is a build_vector of constants which can be formed by using a vspltis[bhw] instruction of the specified element size, return the constant being splatted. The ByteSize field indicates the number of bytes of each element [124] -> [bhw].

unsigned llvm::PPC::getVSPLTImmediate	(	SDNode *	N,
		unsigned	EltSize
	)

getVSPLTImmediate - Return the appropriate VSPLT* immediate to splat the specified isSplatShuffleMask VECTOR_SHUFFLE mask.

bool llvm::PPC::isSplatShuffleMask	(	SDNode *	N,
		unsigned	EltSize
	)

isSplatShuffleMask - Return true if the specified VECTOR_SHUFFLE operand specifies a splat of a single element that is suitable for input to VSPLTB/VSPLTH/VSPLTW.

bool llvm::PPC::isVMRGHShuffleMask	(	SDNode *	N,
		unsigned	UnitSize,
