From: "b. f." <bf1...@googlemail.com> To: bug-follo...@freebsd.org Cc: Scot Hetzel <swhet...@gmail.com> Subject: Re: conf/112997: [patch] Add note about the 'native' mtune option to share/examples/etc/make.conf Date: Sun, 5 Sep 2010 01:22:03 +0000 It is very inefficient to invoke gcc, grep, and/or awk every time this makefile is processed. (In the past, we've gone to a great deal of trouble to avoid this kind of thing: http://lists.freebsd.org/pipermail/freebsd-ports/2008-July/049777.html http://lists.freebsd.org/pipermail/cvs-ports/2008-July/153224.html ) Instead, I think that comments in /etc/make.conf instructing users to how to correctly specify their CPUTYPE would be appropriate. The list of overrides for the base system compiler should be expanded, and perhaps relaxed if CC != cc. But _all_ overrides cannot be removed, and MACHINE_CPU cannot be expanded to include all features recognized by compilers from ports, because the kernel lacks the necessary support for things like SSE5/XOP+FMA4+CVT16, LWP, AVX, etc. b. _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
