4This test serves two purposes:
5
6(1) It documents all existing warnings that currently have no associated -W flag,
7 and ensures that the list never grows.
8
9 If take an existing warning and add a flag, this test will fail. To
10 fix this test, simply remove that warning from the list below.
11
12(2) It prevents us adding new warnings to Clang that have no -W flag. All
13 new warnings should have -W flags.
14
15 If you add a new warning without a flag, this test will fail. To fix
16 this test, simply add a warning group to that warning.
17
18
19The list of warnings below should NEVER grow. It should gradually shrink to 0.
