| 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.

| Function * llvm::Intrinsic::getOrInsertDeclaration | ( | Module * | M, |

Look up the Function declaration of the intrinsic id in the Module M.
If it does not exist, add a declaration and return it. Otherwise, return the existing declaration.
The Tys parameter is for intrinsics with overloaded types (e.g., those using iAny, fAny, vAny, or pAny). For a declaration of an overloaded intrinsic, Tys must provide exactly one type for each overloaded type in the intrinsic.
