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.

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.
