Public Attributes
ArgFlagsTy Flags
MVT VT = MVT::Other
Legalized type of this argument part.
EVT ArgVT
Usually the non-legalized type of the argument, which is the EVT corresponding to the OrigTy IR type.
Type * OrigTy
Original IR type of the argument.
bool Used
unsigned OrigArgIndex
Index original Function's argument.
unsigned PartOffset
Offset in bytes of current input value relative to the beginning of original argument.
Static Public Attributes
static const unsigned NoArgIndex = UINT_MAX
Sentinel value for implicit machine-level input arguments.

◆ getOrigArgIndex()

unsigned llvm::ISD::InputArg::getOrigArgIndex ( ) const inline

◆ isOrigArg()

bool llvm::ISD::InputArg::isOrigArg ( ) const inline

◆ ArgVT

EVT llvm::ISD::InputArg::ArgVT

Usually the non-legalized type of the argument, which is the EVT corresponding to the OrigTy IR type.

However, for post-legalization libcalls, this will be a legalized type.

◆ Flags

◆ NoArgIndex

◆ OrigArgIndex

unsigned llvm::ISD::InputArg::OrigArgIndex

◆ OrigTy

Type* llvm::ISD::InputArg::OrigTy

Original IR type of the argument.

For aggregates, this is the type of an individual aggregate element, not the whole aggregate.

◆ 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.
