SDValue llvm::SPU::get_ILHUvec_imm	(	SDNode *	N,
		SelectionDAG &	DAG,
		MVT	ValueType
	)

get_ILHUvec_imm - Test if this vector is a vector filled with the same value and the value fits into a signed 16-bit constant, and if so, return the constant

Definition at line 1432 of file SPUISelLowering.cpp.

References llvm::SelectionDAG::getTargetConstant(), getVecImm(), llvm::MVT::i32, and llvm::MVT::i64.

SDValue llvm::SPU::get_v2i64_imm	(	SDNode *	N,
		SelectionDAG &	DAG
	)

get_v4i32_imm - Catch-all for general 64-bit constant vectors

Definition at line 1455 of file SPUISelLowering.cpp.

References llvm::SelectionDAG::getTargetConstant(), getVecImm(), and llvm::MVT::i64.

SDValue llvm::SPU::get_v4i32_imm	(	SDNode *	N,
		SelectionDAG &	DAG
	)

get_v4i32_imm - Catch-all for general 32-bit constant vectors

Definition at line 1446 of file SPUISelLowering.cpp.

References llvm::SelectionDAG::getTargetConstant(), getVecImm(), and llvm::MVT::i32.

SDValue llvm::SPU::get_vec_i10imm	(	SDNode *	N,
		SelectionDAG &	DAG,
		MVT	ValueType
	)

get_vec_i10imm - Test if this vector is a vector filled with the same value and the value fits into a signed 10-bit constant, and if so, return the constant

Definition at line 1387 of file SPUISelLowering.cpp.

References llvm::SelectionDAG::getTargetConstant(), getVecImm(), llvm::MVT::i64, and llvm::isS10Constant().

SDValue llvm::SPU::get_vec_i16imm	(	SDNode *	N,
		SelectionDAG &	DAG,
		MVT	ValueType
	)

get_vec_i16imm - Test if this vector is a vector filled with the same value and the value fits into a signed 16-bit constant, and if so, return the constant

Definition at line 1364 of file SPUISelLowering.cpp.

References llvm::SelectionDAG::getTargetConstant(), getVecImm(), and llvm::MVT::i64.

SDValue llvm::SPU::get_vec_i8imm	(	SDNode *	N,
		SelectionDAG &	DAG,
		MVT	ValueType
	)

get_vec_i8imm - Test if this vector is a vector filled with the same value and the value fits into a signed 8-bit constant, and if so, return the constant.

Note:

: The incoming vector is v16i8 because that's the only way we can load constant vectors. Thus, we test to see if the upper and lower bytes are the same value.
