createOp()

CallInst * llvm::dxil::DXILOpBuilder::createOp	(	dxil::OpCode	Op,
		ArrayRef< Value * > &	Args,
		Type *	RetTy = nullptr
	)

Create a call instruction for the given DXIL op.

The arguments must be valid for an overload of the operation.

getOpCodeName()

const char * llvm::dxil::DXILOpBuilder::getOpCodeName ( dxil::OpCode  DXILOp )

static

Return the name of the given opcode.

Definition at line 435 of file DXILOpBuilder.cpp.

tryCreateOp()

Expected< CallInst * > llvm::dxil::DXILOpBuilder::tryCreateOp	(	dxil::OpCode	Op,
		ArrayRef< Value * >	Args,
		Type *	RetTy = nullptr
	)

Try to create a call instruction for the given DXIL op.

Fails if the overload is invalid.
