struct OutputArg

Declaration

struct OutputArg { /* full declaration omitted */ };

Description

OutputArg - This struct carries flags and a value for a single outgoing (actual) argument or outgoing (from the perspective of the caller) return value virtual register.

Declared at: llvm/include/llvm/CodeGen/TargetCallingConv.h:195

Member Variables

public llvm::ISD::ArgFlagsTy Flags

public llvm::MVT VT

public llvm::EVT ArgVT

public bool IsFixed = false

IsFixed - Is this a "fixed" value, ie not passed through a vararg "...".

public unsigned int OrigArgIndex

Index original Function's argument.

public unsigned int PartOffset

Offset in bytes of current output value relative to the beginning of original argument. E.g. if argument was splitted into four 32 bit registers, we got 4 OutputArgs with PartOffsets 0, 4, 8 and 12.

Method Overview

• public OutputArg()
