Declaration

struct CallLowering::CallLoweringInfo { /* full declaration omitted */ };

Declared at: llvm/include/llvm/CodeGen/GlobalISel/CallLowering.h:102

Member Variables

public CallingConv::ID CallConv = CallingConv::C

Calling convention to be used for the call.

public llvm::MachineOperand Callee = MachineOperand::CreateImm(0)

Destination of the call. It should be either a register, globaladdress, or externalsymbol.

public llvm::CallLowering::ArgInfo OrigRet

Descriptor for the return type of the function.

public SmallVector<llvm::CallLowering::ArgInfo, 32> OrigArgs

List of descriptors of the arguments passed to the function.

public llvm::Register SwiftErrorVReg

Valid if the call has a swifterror inout parameter, and contains the vreg that the swifterror should be copied into after the call.

public const llvm::CallBase* CB = nullptr

Original IR callsite corresponding to this call, if available.

public llvm::MDNode* KnownCallees = nullptr

public bool IsMustTailCall = false

True if the call must be tail call optimized.

public bool IsTailCall = false

True if the call passes all target-independent checks for tail call optimization.

public bool LoweredTailCall = false

True if the call was lowered as a tail call. This is consumed by the legalizer. This allows the legalizer to lower libcalls as tail calls.

public bool IsVarArg = false

True if the call is to a vararg function.

public bool CanLowerReturn = true

True if the function's return value can be lowered to registers.

public llvm::Register DemoteRegister

VReg to hold the hidden sret parameter.

public int DemoteStackIndex

The stack index for sret demotion.
