Great. BTW if you did this work it might be worthwhile to go one further step: gcc has a test suite where they run small programs and have a simple facility to scan the resulting assembler code for specific patterns. If you could bring your examples into that format (as in being stand alone compiled and have a simple "yes/no" pattern to check) and let it be included there that might make sure this always keeps working in the future. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
