Ted Kremenek84251262011-08-11 22:06:55 +0000[diff] [blame]1RUN: diagtool list-warnings 2>&1 | FileCheck %s
2
3This test serves two purposes:
4
5(1) It documents all existing warnings that currently have no associated -W flag,
6 and ensures that the list never grows.
7
8 If take an existing warning and add a flag, this test will fail. To
9 fix this test, simply remove that warning from the list below.
10
11(2) It prevents us adding new warnings to Clang that have no -W flag. All
12 new warnings should have -W flags.
13
14 If you add a new warning without a flag, this test will fail. To fix
15 this test, simply add a warning group to that warning.
16
17
18The list of warnings below should NEVER grow. It should gradually shrink to 0.
