Declared at: llvm/include/llvm/CodeGen/GlobalISel/CallLowering.h:71

Member Variables

public CallingConv::ID CallConv = CallingConv::C

Calling convention to be used for the call.

public llvm::MachineOperand Callee

public llvm::CallLowering::ArgInfo OrigRet

public SmallVector<llvm::CallLowering::ArgInfo, 8> OrigArgs

public llvm::Register SwiftErrorVReg = 0

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

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.
