And it's a RISC architecture no complex instructions - that means you often need more instructions. And all instructions are equal in length, while i386 has some shorter instructions. Finaly the gcc on 4.x does a lot of padding. gcc-3.1 compiled binaries are usually smaller. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
