Functions
std::optional< VFInfo >	llvm::VFABI::tryDemangleForVFABI (StringRef MangledName, const FunctionType *FTy)
	Function to construct a VFInfo out of a mangled names in the following format:
VFParamKind	llvm::VFABI::getVFParamKindFromString (const StringRef Token)
	Retrieve the VFParamKind from a string token.
void	llvm::VFABI::getVectorVariantNames (const CallInst &CI, SmallVectorImpl< std::string > &VariantMappings)
	Populates a set of strings representing the Vector Function ABI variants associated to the CallInst CI.
FunctionType *	llvm::VFABI::createFunctionType (const VFInfo &Info, const FunctionType *ScalarFTy)
	Constructs a FunctionType by applying vector function information to the type of a matching scalar function.
void	llvm::VFABI::setVectorVariantNames (CallInst *CI, ArrayRef< std::string > VariantMappings)
	Overwrite the Vector Function ABI variants attribute with the names provide in VariantMappings.

Variables
static constexpr char const *	llvm::VFABI::_LLVM_ = "_LLVM_"
	LLVM Internal VFABI ISA token for vector functions.
static constexpr char const *	llvm::VFABI::_LLVM_Scalarize_ = "_LLVM_Scalarize_"
	Prefix for internal name redirection for vector function that tells the compiler to scalarize the call using the scalar name of the function.
static constexpr char const *	llvm::VFABI::MappingsAttrName = "vector-function-abi-variant"
