virtual void	assignValueToAddress (const ArgInfo &Arg, unsigned ValRegIndex, Register Addr, LLT MemTy, const MachinePointerInfo &MPO, const CCValAssign &VA)
	An overload which takes an ArgInfo if additional information about the arg is needed.
virtual unsigned	assignCustomValue (ArgInfo &Arg, ArrayRef< CCValAssign > VAs, std::function< void()> *Thunk=nullptr)
	Handle custom values, which may be passed into one or more of `VAs`.
void	copyArgumentMemory (const ArgInfo &Arg, Register DstPtr, Register SrcPtr, const MachinePointerInfo &DstPtrInfo, Align DstAlign, const MachinePointerInfo &SrcPtrInfo, Align SrcAlign, uint64_t MemSize, CCValAssign &VA) const
	Do a memory copy of `MemSize` bytes from `SrcPtr` to `DstPtr`.
Register	extendRegister (Register ValReg, const CCValAssign &VA, unsigned MaxSizeBits=0)
	Extend a register to the location type given in VA, capped at extending to at most MaxSize bits.

		Register	Addr,
		LLT	MemTy,
		const MachinePointerInfo &	MPO,
		const CCValAssign &	VA )

The specified value has been assigned to a stack location.

Load or store it there, with appropriate extension if necessary.

Implements llvm::CallLowering::ValueHandler.

◆ assignValueToReg()

Register M68kOutgoingArgHandler::getStackAddress	(	uint64_t	MemSize,
		int64_t	Offset,
		MachinePointerInfo &	MPO,
		ISD::ArgFlagsTy	Flags )

inlineoverridevirtual

Materialize a VReg containing the address of the specified stack-based object.

This is either based on a FrameIndex or direct SP manipulation, depending on the context. MPO should be initialized to an appropriate description of the address created.

Implements llvm::CallLowering::ValueHandler.
