struct InputArg

Declaration

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

Description

InputArg - This struct carries flags and type information about a single incoming (formal) argument or incoming (from the perspective of the caller) return value virtual register.

Declared at: llvm/include/llvm/CodeGen/TargetCallingConv.h:157

Member Variables

public llvm::ISD::ArgFlagsTy Flags

public llvm::MVT VT = MVT::Other

public llvm::EVT ArgVT

public bool Used = false

public unsigned int OrigArgIndex

Index original Function's argument.

public unsigned int PartOffset

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

public static const unsigned int NoArgIndex = (2147483647 * 2U + 1U)

Sentinel value for implicit machine-level input arguments.
