[IBM XLC++] many warnings 1500-029: subprogram could not be inlined

• Key: STDCXX-894
• Type: Bug
• Status: Open
• Priority: Minor
• Assignee: Unassigned
• Reporter: Martin Sebor
• Component/s: Tests
• Affects Version/s: 4.2.0
• Fix Version/s: 4.2.2

Description

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.
