1 RUN: diagtool list-warnings 2>&1 | FileCheck %s 2 3 This 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 18 The list of warnings below should NEVER grow. It should gradually shrink to 0. 19 20 CHECK: Warnings without flags (253): 21 CHECK-NEXT: ext_anonymous_struct_union_qualified 22 CHECK-NEXT: ext_binary_literal 23 CHECK-NEXT: ext_cast_fn_obj 24
