◆ OrigArgIndex

unsigned llvm::ISD::InputArg::OrigArgIndex

Index original Function's argument.

◆ 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.
