:> :> -O6 is too much; -O3 is the highest level tested for by egcs. : :But specifying something too high (-O99) doesn't hurt - I'm using -O6 for :gcc 2.95.1 (which, by the way, compiles almost everything in 3.3-RELEASE :and 4.0-CURRENT, the only thing still troubling me with it is the kernel). : :LLaP :bero I tend not to like the higher optimization levels because they cause the compiler to attempt to turn static functions into inlines and, in my opinion, it doesn't do a very good job of selecting which functions to convert. The result is that I see bloated binaries with no performance gain to show for it. EGCS's -Os is my favorite. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
