So you disassembled and examined it? Or did you benchmark it? Where are your benchmarks? Other people have already put up theirs. Or perhaps you looked at the gcc source code and found bugs in it? Where are your patches? Many FreeBSD users would be interested, if there really is a performance improvement. > You could do better dashing it off in assembly language. Well, that's always true. No compiler can beat well-written assembly language. - Rahul To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
