Member Data Documentation

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

ArgFlagsTy llvm::ISD::InputArg::Flags

Definition at line 205 of file TargetCallingConv.h.

Referenced by handleCMSEValue(), InputArg(), llvm::SITargetLowering::LowerFormalArguments(), and processPSInputArgs().

NoArgIndex

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

static

Sentinel value for implicit machine-level input arguments.

Definition at line 220 of file TargetCallingConv.h.

Referenced by getOrigArgIndex(), isOrigArg(), llvm::TargetLowering::LowerCallTo(), and llvm::FastISel::lowerCallTo().

OrigArgIndex

unsigned llvm::ISD::InputArg::OrigArgIndex

Index original Function's argument.

Definition at line 218 of file TargetCallingConv.h.

Referenced by getOrigArgIndex(), InputArg(), and isOrigArg().

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.

Definition at line 214 of file TargetCallingConv.h.

Referenced by InputArg().

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

Definition at line 215 of file TargetCallingConv.h.

VT

MVT llvm::ISD::InputArg::VT = MVT::Other

Legalized type of this argument part.
