> When compiled with IBM XLC++ with optimization enabled, many tests produce warning 1500-029: subprogram could not be inlined. Some of these warnings are issued for tests that explicitly instantiate algorithms on contrived user-defined types to detect incorrect assumptions made in the tests about the types they are required to operate on. The warnings could safely be suppressed in these cases.
> In other cases, these warnings may indicate inefficiencies that should be investigated and corrected.
