Compiler warnings can be considered as checkers, since they are also indicating suspicious constructions in the source code. In case of clang compiler the warnings are available as clang-diagnostic-... checkers.

This feature should be available for gcc compiler, too. The gcc warnings (gcc --help=warnings) should be exposed on CodeChecker interface as gcc-diagnostic-... checkers when running CodeChecker checkers --analyzers gcc. Also, it should be possible to enable/disable them when --enable/--disable flags are used respectively.
