Actually it is surprising that the compiler hasn't been optimising away our write_cr0() entirely. Perhaps it special cases asm blocks with no outputs. Adding the volatile keyword makes a lot of sense anyway. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
