◆ assignValueToAddress()

void M68kOutgoingArgHandler::assignValueToAddress ( Register  ValVReg,
Register  Addr,
LLT  MemTy,
const MachinePointerInfo MPO,
const CCValAssign VA 
)
inlineoverridevirtual

The specified value has been assigned to a stack location.

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

Implements llvm::CallLowering::ValueHandler.

References Addr, llvm::MachineFunction::getMachineMemOperand(), llvm::inferAlignFromPtrInfo(), and llvm::MachineMemOperand::MOStore.

◆ assignValueToReg()

void M68kOutgoingArgHandler::assignValueToReg ( Register  ValVReg,
Register  PhysReg,
const CCValAssign VA 
)
inlineoverridevirtual

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.

Implements llvm::CallLowering::ValueHandler.

Definition at line 59 of file M68kCallLowering.cpp.

References llvm::RegState::Implicit.

◆ getStackAddress()

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.
