Classes
struct	llvm::Intrinsic::IITDescriptor
	This is a type descriptor which explains the type requirements of an intrinsic. More...

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.
namespace	llvm::Intrinsic
	This namespace contains an enum with a value for every intrinsic/builtin function known by LLVM.

Macros

Enumerations
enum	llvm::Intrinsic::IndependentIntrinsics : unsigned { llvm::Intrinsic::not_intrinsic = 0 }
enum	llvm::Intrinsic::MatchIntrinsicTypesResult { llvm::Intrinsic::MatchIntrinsicTypes_Match = 0 , llvm::Intrinsic::MatchIntrinsicTypes_NoMatchRet = 1 , llvm::Intrinsic::MatchIntrinsicTypes_NoMatchArg = 2 }

Functions
LLVM_ABI StringRef	llvm::Intrinsic::getName (ID id)
	Return the LLVM name for an intrinsic, such as "llvm.ppc.altivec.lvx".
LLVM_ABI StringRef	llvm::Intrinsic::getBaseName (ID id)
	Return the LLVM name for an intrinsic, without encoded types for overloading, such as "llvm.ssa.copy".
LLVM_ABI std::string	llvm::Intrinsic::getName (ID Id, ArrayRef< Type * > Tys, Module *M, FunctionType *FT=nullptr)
	Return the LLVM name for an intrinsic, such as "llvm.ppc.altivec.lvx" or "llvm.ssa.copy.p0s_s.1".
LLVM_ABI std::string	llvm::Intrinsic::getNameNoUnnamedTypes (ID Id, ArrayRef< Type * > Tys)
	Return the LLVM name for an intrinsic.
LLVM_ABI FunctionType *	llvm::Intrinsic::getType (LLVMContext &Context, ID id, ArrayRef< Type * > Tys={})
	Return the function type for an intrinsic.
LLVM_ABI bool	llvm::Intrinsic::isOverloaded (ID id)
	Returns true if the intrinsic can be overloaded.
LLVM_ABI bool	llvm::Intrinsic::isTargetIntrinsic (ID IID)
	isTargetIntrinsic - Returns true if IID is an intrinsic specific to a certain target.
LLVM_ABI ID	llvm::Intrinsic::lookupIntrinsicID (StringRef Name)
	This does the actual lookup of an intrinsic ID which matches the given function name.
LLVM_ABI AttributeList	llvm::Intrinsic::getAttributes (LLVMContext &C, ID id, FunctionType *FT)
	Return the attributes for an intrinsic.
LLVM_ABI AttributeSet	llvm::Intrinsic::getFnAttributes (LLVMContext &C, ID id)
	Return the function attributes for an intrinsic.
LLVM_ABI Function *	llvm::Intrinsic::getOrInsertDeclaration (Module *M, ID id, ArrayRef< Type * > Tys={})
	Look up the Function declaration of the intrinsic id in the Module M.
LLVM_ABI Function *	llvm::Intrinsic::getDeclarationIfExists (const Module *M, ID id)
	Look up the Function declaration of the intrinsic id in the Module M and return it if it exists.
LLVM_ABI Function *	llvm::Intrinsic::getDeclarationIfExists (Module *M, ID id, ArrayRef< Type * > Tys, FunctionType *FT=nullptr)
	This version supports overloaded intrinsics.
LLVM_ABI ID	llvm::Intrinsic::getIntrinsicForClangBuiltin (StringRef TargetPrefix, StringRef BuiltinName)
	Map a Clang builtin name to an intrinsic ID.
LLVM_ABI ID	llvm::Intrinsic::getIntrinsicForMSBuiltin (StringRef TargetPrefix, StringRef BuiltinName)
	Map a MS builtin name to an intrinsic ID.
LLVM_ABI bool	llvm::Intrinsic::isConstrainedFPIntrinsic (ID QID)
	Returns true if the intrinsic ID is for one of the "Constrained Floating-Point Intrinsics".
LLVM_ABI bool	llvm::Intrinsic::hasConstrainedFPRoundingModeOperand (ID QID)
	Returns true if the intrinsic ID is for one of the "Constrained Floating-Point Intrinsics" that take rounding mode metadata.
LLVM_ABI void	llvm::Intrinsic::getIntrinsicInfoTableEntries (ID id, SmallVectorImpl< IITDescriptor > &T)
	Return the IIT table descriptor for the specified intrinsic into an array of IITDescriptors.
LLVM_ABI MatchIntrinsicTypesResult	llvm::Intrinsic::matchIntrinsicSignature (FunctionType *FTy, ArrayRef< IITDescriptor > &Infos, SmallVectorImpl< Type * > &ArgTys)
	Match the specified function type with the type constraints specified by the .td file.
LLVM_ABI bool	llvm::Intrinsic::matchIntrinsicVarArg (bool isVarArg, ArrayRef< IITDescriptor > &Infos)
	Verify if the intrinsic has variable arguments.
LLVM_ABI bool	llvm::Intrinsic::getIntrinsicSignature (Intrinsic::ID, FunctionType *FT, SmallVectorImpl< Type * > &ArgTys)
	Gets the type arguments of an intrinsic call by matching type contraints specified by the .td file.
LLVM_ABI bool	llvm::Intrinsic::getIntrinsicSignature (Function *F, SmallVectorImpl< Type * > &ArgTys)
	Same as previous, but accepts a Function instead of ID and FunctionType.
LLVM_ABI std::optional< Function * >	llvm::Intrinsic::remangleIntrinsicFunction (Function *F)
LLVM_ABI Intrinsic::ID	llvm::Intrinsic::getInterleaveIntrinsicID (unsigned Factor)
	Returns the corresponding llvm.vector.interleaveN intrinsic for factor N.
