Public Member Functions

 M68kIncomingValueHandler (MachineIRBuilder &MIRBuilder, MachineRegisterInfo &MRI)
- Public Member Functions inherited from llvm::CallLowering::IncomingValueHandler
 IncomingValueHandler (MachineIRBuilder &MIRBuilder, MachineRegisterInfo &MRI)
Register buildExtensionHint (const CCValAssign &VA, Register SrcReg, LLT NarrowTy)
 Insert G_ASSERT_ZEXT/G_ASSERT_SEXT or other hint instruction based on VA, returning the new register if a hint was inserted.
void assignValueToReg (Register ValVReg, Register PhysReg, const CCValAssign &VA) override
 Provides a default implementation for argument handling.
- Public Member Functions inherited from llvm::CallLowering::ValueHandler
 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 Register getStackAddress (uint64_t MemSize, int64_t Offset, MachinePointerInfo &MPO, ISD::ArgFlagsTy Flags)=0
 Materialize a VReg containing the address of the specified stack-based object.
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 assignValueToReg (Register ValVReg, Register PhysReg, const CCValAssign &VA)=0
 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.
virtual void assignValueToAddress (Register ValVReg, Register Addr, LLT MemTy, const MachinePointerInfo &MPO, const CCValAssign &VA)=0
 The specified value has been assigned to a stack location.
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.
