What do you mean by "supported"? Valid C code that follows MISRA rules can be compiled by GCC, but I doubt that's what you mean. If you want something to check that the rules are followed, that's not what GCC is for. GCC is a compiler. There are static analysis tools that can check for conformance to guidelines like MISRA.
