class TargetLibraryInfo

Implementation of the target library information.

This class constructs tables that hold the target library information and make it available. However, it is somewhat expensive to compute and only depends on the triple. So users typically interact with the [TargetLibraryInfo](classllvm%5F1%5F1TargetLibraryInfo.html "Provides information about what library functions are available for the current target.") wrapper below.
