1 RUN: diagtool list-warnings > %t 2>&1 2 RUN: FileCheck --input-file=%t %s 3 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 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 19 The list of warnings below should NEVER grow. It should gradually shrink to 0. 20 21 CHECK: Warnings without flags (159): 22 CHECK-NEXT: ext_delete_void_ptr_operand 23 CHECK-NEXT: ext_enum_friend 24 CHECK-NEXT: ext_expected_semi_decl_list 25
