Member Data Documentation

◆ ArgVT

EVT llvm::ISD::InputArg::ArgVT

◆ Flags

ArgFlagsTy llvm::ISD::InputArg::Flags

◆ NoArgIndex

const unsigned llvm::ISD::InputArg::NoArgIndex = UINT_MAX
static

Sentinel value for implicit machine-level input arguments.

Definition at line 204 of file TargetCallingConv.h.

Referenced by getOrigArgIndex(), and isOrigArg().

◆ OrigArgIndex

unsigned llvm::ISD::InputArg::OrigArgIndex

Index original Function's argument.

Definition at line 202 of file TargetCallingConv.h.

Referenced by getOrigArgIndex(), and isOrigArg().

◆ PartOffset

unsigned llvm::ISD::InputArg::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.

◆ Used

bool llvm::ISD::InputArg::Used = false

◆ VT
