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.
