| 4 | This 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 you take an existing warning and add a flag, this test will fail. |
|---|
| 10 | To 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 | |
|---|
| 19 | The list of warnings below should NEVER grow. It should gradually shrink to 0. |
