Detailed Description

TargetLibraryInfo - This immutable pass captures information about what library functions are available for the current target, and allows a frontend to disable optimizations through -fno-builtin etc.

void TargetLibraryInfo::disableAllFunctions

(

)

disableAllFunctions - This disables all builtins, which is used for options like -fno-builtin.

Definition at line 646 of file TargetLibraryInfo.cpp.

References llvm::LibFunc::memset.

bool TargetLibraryInfo::getLibFunc	(	StringRef	funcName,
		LibFunc::Func &	F
	)		const

getLibFunc - Search for a particular function name. If it is one of the known library functions, return true and set F to the corresponding value.
