Member Data Documentation

◆ CallConv

CallingConv::ID llvm::CallLowering::CallLoweringInfo::CallConv = CallingConv::C

Calling convention to be used for the call.

Definition at line 104 of file CallLowering.h.

◆ Callee

MachineOperand llvm::CallLowering::CallLoweringInfo::Callee = MachineOperand::CreateImm(0)

Destination of the call.

It should be either a register, globaladdress, or externalsymbol.

Definition at line 108 of file CallLowering.h.

◆ CanLowerReturn

bool llvm::CallLowering::CallLoweringInfo::CanLowerReturn = true

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

Definition at line 140 of file CallLowering.h.

◆ CB

const CallBase* llvm::CallLowering::CallLoweringInfo::CB = nullptr

Original IR callsite corresponding to this call, if available.

Definition at line 121 of file CallLowering.h.

◆ CFIType

const ConstantInt* llvm::CallLowering::CallLoweringInfo::CFIType = nullptr

Expected type identifier for indirect calls with a CFI check.

Definition at line 149 of file CallLowering.h.

◆ DemoteRegister

Register llvm::CallLowering::CallLoweringInfo::DemoteRegister

VReg to hold the hidden sret parameter.

Definition at line 143 of file CallLowering.h.

◆ DemoteStackIndex

int llvm::CallLowering::CallLoweringInfo::DemoteStackIndex

The stack index for sret demotion.

Definition at line 146 of file CallLowering.h.

◆ IsMustTailCall

bool llvm::CallLowering::CallLoweringInfo::IsMustTailCall = false

True if the call must be tail call optimized.

Definition at line 126 of file CallLowering.h.

◆ IsTailCall

bool llvm::CallLowering::CallLoweringInfo::IsTailCall = false

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

Definition at line 130 of file CallLowering.h.

◆ IsVarArg

bool llvm::CallLowering::CallLoweringInfo::IsVarArg = false

True if the call is to a vararg function.

Definition at line 137 of file CallLowering.h.

◆ KnownCallees

MDNode* llvm::CallLowering::CallLoweringInfo::KnownCallees = nullptr

Definition at line 123 of file CallLowering.h.

◆ LoweredTailCall

bool llvm::CallLowering::CallLoweringInfo::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.

Definition at line 134 of file CallLowering.h.

◆ OrigArgs

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

List of descriptors of the arguments passed to the function.

Definition at line 114 of file CallLowering.h.

◆ OrigRet

ArgInfo llvm::CallLowering::CallLoweringInfo::OrigRet

Descriptor for the return type of the function.

Definition at line 111 of file CallLowering.h.

◆ SwiftErrorVReg

Register llvm::CallLowering::CallLoweringInfo::SwiftErrorVReg

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

Definition at line 118 of file CallLowering.h.
