Gets the type arguments of an intrinsic call by matching type contraints specified by the .td file.

Returns false if the given function is not a valid intrinsic call.

std::string llvm::Intrinsic::getName | ( | ID | Id, |

) |
Return the LLVM name for an intrinsic, such as "llvm.ppc.altivec.lvx" or "llvm.ssa.copy.p0s_s.1".
Note, this version of getName supports overloads. This is less efficient than the StringRef version of this function. If no overloads are required, it is safe to use this version, but better to use the StringRef version. If one of the types is based on an unnamed type, a function type will be computed. Providing FT will avoid this computation.

Return the LLVM name for an intrinsic.
This is a special version only to be used by LLVMIntrinsicCopyOverloadedName. It only supports overloads based on named types.

int llvm::Intrinsic::lookupLLVMIntrinsicByName | ( | ArrayRef< const char * > | NameTable, |

Looks up Name in NameTable via binary search.
NameTable must be sorted and all entries must start with "llvm.". If NameTable contains an exact match for Name or a prefix of Name followed by a dot, its index in NameTable is returned. Otherwise, -1 is returned.
