◆ CallConv

◆ Callee

Destination of the call.

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

Definition at line 111 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 149 of file CallLowering.h.

◆ CB

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

Original IR callsite corresponding to this call, if available.

Definition at line 127 of file CallLowering.h.

◆ CFIType

◆ ConvergenceCtrlToken

Valid if the call is a controlled convergent operation.

Definition at line 124 of file CallLowering.h.

◆ DeactivationSymbol

GlobalValue* llvm::CallLowering::CallLoweringInfo::DeactivationSymbol = nullptr

◆ DemoteRegister

VReg to hold the hidden sret parameter.

Definition at line 152 of file CallLowering.h.

◆ DemoteStackIndex

int llvm::CallLowering::CallLoweringInfo::DemoteStackIndex

◆ IsConvergent

bool llvm::CallLowering::CallLoweringInfo::IsConvergent = true

True if this call results in convergent operations.

Definition at line 161 of file CallLowering.h.

◆ IsMustTailCall

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

True if the call must be tail call optimized.

Definition at line 135 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 139 of file CallLowering.h.

◆ IsVarArg

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

True if the call is to a vararg function.

Definition at line 146 of file CallLowering.h.

◆ KnownCallees

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

◆ 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 143 of file CallLowering.h.

◆ OrigArgs

List of descriptors of the arguments passed to the function.

Definition at line 117 of file CallLowering.h.

◆ OrigRet

ArgInfo llvm::CallLowering::CallLoweringInfo::OrigRet

Descriptor for the return type of the function.

Definition at line 114 of file CallLowering.h.

◆ PAI

std::optional<PtrAuthInfo> llvm::CallLowering::CallLoweringInfo::PAI

The auth-call information in the "ptrauth" bundle, if present.

Definition at line 132 of file CallLowering.h.

◆ SwiftErrorVReg

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