In my experience it just bloats .text for most projects because of its aggressive inlining. I would use -O2. That's a good question. All that patch really did was move the optimisation default into Config.mk, and the general choice throughout the Xen tree was -O3. But it isn't clear that's best. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
