-----------------------------------
Assignee: Travis Vitek
> [IBM XLC++] many warnings 1500-029: subprogram could not be inlined
> -------------------------------------------------------------------
>
> Key: STDCXX-894
> URL: https://issues.apache.org/jira/browse/STDCXX-894
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Tests
> Affects Versions: 4.2.0
> Reporter: Martin Sebor
> Assignee: Travis Vitek
> Priority: Minor
> Fix For: 4.2.2
>
> Original Estimate: 6h
> Remaining Estimate: 6h
>
> 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.
