| // Overall warning settings: the 'all' and 'extra' classes plus convert warnings into errors. |
| // -Wall, // Standard known-to-be-bugs warnings. |
| // -Wextra, // Many useful extra warnings. |
| // -Werror, // All warnings as errors. |
| // |
| // Deprecation support: without these one can't rationally deprecate things. |
| // -Wno-error=deprecated, // Deprecation warnings are never errors. |
| // -Wno-error=deprecated-implementations, // Deprecation warnings are never errors. |
| // |
| // Useful warnings that are not in the 'all' and 'extra' classes. |
| // -Wcast-align, // Casting a pointer such that alignment is broken. |
| // -Wconversion, // Numeric conversion warnings. |
| // -Wdocumentation, // Warn when documentation is out of date. |
| // -Wformat=2, // Check printf-style format strings more strictly. |
| // -Wimplicit-atomic-properties, // Dynamic properties should be non-atomic. |
| // -Wmissing-declarations, // Warn if a global function is defined without a previous declaration. |
| // -Wmissing-prototypes, // Global function is defined without a previous prototype. |
| // -Wno-unused-parameter, // Do not warn on unused parameters. |
| // -Woverlength-strings, // Strings longer than the C maximum. |
| // -Wshadow, // Local variable shadows another variable, parameter, etc. |
| // -Wstrict-selector-match, // Compiler can't figure out the right selector. |
| // -Wundeclared-selector, // Compiler doesn't see a selector. |
| // -Wunreachable-code, // Code will never be reached. |
