LLVM: M68kOutgoingArgHandler Struct Reference (original) (raw)

Public Member Functions
	M68kOutgoingArgHandler (MachineIRBuilder &MIRBuilder, MachineRegisterInfo &MRI, MachineInstrBuilder MIB)
void	assignValueToReg (Register ValVReg, Register PhysReg, const CCValAssign &VA) override
	The specified value has been assigned to a physical register, handle the appropriate COPY (either to or from) and mark any relevant uses/defines as needed.
void	assignValueToAddress (Register ValVReg, Register Addr, LLT MemTy, const MachinePointerInfo &MPO, const CCValAssign &VA) override
	The specified value has been assigned to a stack location.
Register	getStackAddress (uint64_t Size, int64_t Offset, MachinePointerInfo &MPO, ISD::ArgFlagsTy Flags) override
	Materialize a VReg containing the address of the specified stack-based object.

	ValueHandler (bool IsIncoming, MachineIRBuilder &MIRBuilder, MachineRegisterInfo &MRI)
virtual	~ValueHandler ()=default
bool	isIncomingArgumentHandler () const
	Returns true if the handler is dealing with incoming arguments, i.e.
virtual LLT	getStackValueStoreType (const DataLayout &DL, const CCValAssign &VA, ISD::ArgFlagsTy Flags) const
	Return the in-memory size to write for the argument at VA.
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.
