I guess the 3Dnow! cpuid bit leaked in via the qemu merge. I guess two fixes are needed: - remove the 3Dnow! bit - add emulation for prefetchw (easy, as it doesn't need to do anything) to support live migration from AMD to Intel -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
