Member Function Documentation

getDeclaration()

virtual Function * llvm::TargetIntrinsicInfo::getDeclaration ( Module *  M, unsigned  ID, Type **  Tys = nullptr, unsigned  numTys = 0  ) const

pure virtual

Create or insert an LLVM Function declaration for an intrinsic, and return it.

The Tys and numTys are for intrinsics with overloaded types. See above for more information.

getIntrinsicID()

unsigned TargetIntrinsicInfo::getIntrinsicID ( const Function *  F ) const

virtual

Return the target intrinsic ID of a function, or 0.

Definition at line 22 of file TargetIntrinsicInfo.cpp.

References F, llvm::StringMapEntry< ValueTy >::getKeyData(), llvm::StringMapEntryBase::getKeyLength(), and lookupName().

getName()

virtual std::string llvm::TargetIntrinsicInfo::getName ( unsigned  IID, Type **  Tys = nullptr, unsigned  numTys = 0  ) const

pure virtual

Return the name of a target intrinsic, e.g.

"llvm.bfin.ssync". The Tys and numTys parameters are for intrinsics with overloaded types (e.g., those using iAny or fAny). For a declaration for an overloaded intrinsic, Tys should point to an array of numTys pointers to Type, and must provide exactly one type for each overloaded type in the intrinsic.

isOverloaded()

virtual bool llvm::TargetIntrinsicInfo::isOverloaded ( unsigned  IID ) const

pure virtual

Returns true if the intrinsic can be overloaded.

lookupName() [1/2]

virtual unsigned llvm::TargetIntrinsicInfo::lookupName ( const char *  Name, unsigned  Len  ) const

pure virtual

Look up target intrinsic by name.

Return intrinsic ID or 0 for unknown names.
