- RUN: diagtool list-warnings > %t 2>&1
- RUN: FileCheck --input-file=%t %s
- This test serves two purposes:
- (1) It documents all existing warnings that currently have no associated -W flag,
- and ensures that the list never grows.
- If take an existing warning and add a flag, this test will fail. To
- fix this test, simply remove that warning from the list below.
- (2) It prevents us adding new warnings to Clang that have no -W flag. All
- new warnings should have -W flags.
- If you add a new warning without a flag, this test will fail. To fix
- this test, simply add a warning group to that warning.
- The list of warnings below should NEVER grow. It should gradually shrink to 0.
