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 (84): 22 CHECK-NEXT: ext_excess_initializers 23 CHECK-NEXT: ext_excess_initializers_in_char_array_initializer 24 CHECK-NEXT: ext_expected_semi_decl_list 25 CHECK-NEXT: ext_explicit_specialization_storage_class 26 CHECK-NEXT: ext_initializer_string_for_char_array_too_long 27 CHECK-NEXT: ext_missing_declspec 28 CHECK-NEXT: ext_missing_whitespace_after_macro_name 29 CHECK-NEXT: ext_new_paren_array_nonconst 30 CHECK-NEXT: ext_plain_complex 31 CHECK-NEXT: ext_template_arg_extra_parens 32 CHECK-NEXT: ext_typecheck_comparison_of_pointer_integer 33 CHECK-NEXT: ext_typecheck_cond_incompatible_operands 34 CHECK-NEXT: ext_typecheck_cond_incompatible_operands_nonstandard 35 CHECK-NEXT: ext_typecheck_ordered_comparison_of_function_pointers 36 CHECK-NEXT: ext_typecheck_ordered_comparison_of_pointer_integer 37 CHECK-NEXT: ext_using_undefined_std 38 CHECK-NEXT: pp_invalid_string_literal 39 CHECK-NEXT: pp_out_of_date_dependency 40 CHECK-NEXT: pp_poisoning_existing_macro 41 CHECK-NEXT: w_asm_qualifier_ignored 42 CHECK-NEXT: warn_accessor_property_type_mismatch 43 CHECK-NEXT: warn_arcmt_nsalloc_realloc 44 CHECK-NEXT: warn_asm_label_on_auto_decl 45 CHECK-NEXT: warn_c_kext 46 CHECK-NEXT: warn_call_to_pure_virtual_member_function_from_ctor_dtor 47 CHECK-NEXT: warn_call_wrong_number_of_arguments 48 CHECK-NEXT: warn_case_empty_range 49 CHECK-NEXT: warn_char_constant_too_large 50 CHECK-NEXT: warn_collection_expr_type 51 CHECK-NEXT: warn_conflicting_variadic 52 CHECK-NEXT: warn_conv_to_base_not_used 53 CHECK-NEXT: warn_conv_to_self_not_used 54 CHECK-NEXT: warn_conv_to_void_not_used 55 CHECK-NEXT: warn_delete_array_type 56 CHECK-NEXT: warn_double_const_requires_fp64 57 CHECK-NEXT: warn_drv_assuming_mfloat_abi_is 58 CHECK-NEXT: warn_drv_clang_unsupported 59 CHECK-NEXT: warn_drv_objc_gc_unsupported 60 CHECK-NEXT: warn_drv_pch_not_first_include 61 CHECK-NEXT: warn_dup_category_def 62 CHECK-NEXT: warn_duplicate_protocol_def 63 CHECK-NEXT: warn_enum_value_overflow 64 CHECK-NEXT: warn_expected_qualified_after_typename 65 CHECK-NEXT: warn_extraneous_char_constant 66 CHECK-NEXT: warn_fe_cc_log_diagnostics_failure 67 CHECK-NEXT: warn_fe_cc_print_header_failure 68 CHECK-NEXT: warn_fe_macro_contains_embedded_newline 69 CHECK-NEXT: warn_file_asm_volatile 70 CHECK-NEXT: warn_ignoring_ftabstop_value 71 CHECK-NEXT: warn_implements_nscopying 72 CHECK-NEXT: warn_incompatible_qualified_id 73 CHECK-NEXT: warn_inline_namespace_reopened_noninline 74 CHECK-NEXT: warn_invalid_asm_cast_lvalue 75 CHECK-NEXT: warn_maynot_respond 76 CHECK-NEXT: warn_method_param_redefinition 77 CHECK-NEXT: warn_missing_case_for_condition 78 CHECK-NEXT: warn_missing_dependent_template_keyword 79 CHECK-NEXT: warn_missing_whitespace_after_macro_name 80 CHECK-NEXT: warn_mt_message 81 CHECK-NEXT: warn_no_constructor_for_refconst 82 CHECK-NEXT: warn_not_compound_assign 83 CHECK-NEXT: warn_objc_property_copy_missing_on_block 84 CHECK-NEXT: warn_objc_protocol_qualifier_missing_id 85 CHECK-NEXT: warn_on_superclass_use 86 CHECK-NEXT: warn_partial_specs_not_deducible 87 CHECK-NEXT: warn_pp_convert_to_positive 88 CHECK-NEXT: warn_pp_expr_overflow 89 CHECK-NEXT: warn_pp_line_decimal 90 CHECK-NEXT: warn_pragma_pack_pop_identifer_and_alignment 91 CHECK-NEXT: warn_pragma_pack_show 92 CHECK-NEXT: warn_property_getter_owning_mismatch 93 CHECK-NEXT: warn_register_objc_catch_parm 94 CHECK-NEXT: warn_related_result_type_compatibility_class 95 CHECK-NEXT: warn_related_result_type_compatibility_protocol 96 CHECK-NEXT: warn_template_export_unsupported 97 CHECK-NEXT: warn_template_spec_extra_headers 98 CHECK-NEXT: warn_tentative_incomplete_array 99 CHECK-NEXT: warn_typecheck_function_qualifiers 100 CHECK-NEXT: warn_undef_interface 101 CHECK-NEXT: warn_undef_interface_suggest 102 CHECK-NEXT: warn_undef_protocolref 103 CHECK-NEXT: warn_use_out_of_scope_declaration 104 CHECK-NEXT: warn_weak_identifier_undeclared 105 CHECK-NEXT: warn_weak_import 106 107 The list of warnings in -Wpedantic should NEVER grow. 108 109 CHECK: Number in -Wpedantic (not covered by other -W flags): 27 110
