I guess I jumped the gun a bit. When targeting a corei7 based chip, Yocto uses the following CFLAGS for the packages it builds: -march=corei7 -mtune=corei7 -mfpmath=sse -msse4.2 The issue is the -mfpmath value. -- Doug Goldstein _______________________________________________ Xen-devel mailing list [email protected] http://lists.xen.org/xen-devel
