That's the way the compiler is called for kernel compilation. It tells the cpu type for c code optimizing and it tells the instruction set for available assembly instructions, which is not set by CPUTYPE and defaults to ev56. The reason is that you can comile ev4 kernel but still can use ev56 assembly sections in specific parts to get multiple cpus supported in a combined kernel. -- 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
