This situation is a bit different than loosing 80386 support in the binaries where we can expect owners to have acces to at least a pentium to build the binaries their self. Please add at least a note in UPDATING so non BWX owners don't forget to update their /etc/make.conf. EV6 would be a bad default as it includes Multimedia extensions which are not available on ev56 machines and exclude much more machines without such a big performance win. Also it would break kernel builds as we explicitly tell the assembler to understand ev56 assembly - maybe it's a good idea to just raise that. -- 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 cvs-all" in the body of the message
