Yeah, true. Please ignore the patch folks.
cheers, Kyle
Simulators can be fixed, even if it takes time; for something like
clflush this is easier since clflush can be implemented as a simple noop
for most of them.
I just verified that Bochs 2.3.0 lacks this CPUID bit whereas the
current version, 2.3.6, enables CLFLUSH iff SSE2 is enabled. Qemu 0.9.0
has CLFLUSH. Andi, do you happen to know of any specific simulators
which are problematic? I would assume any recent version of SimNow is
up to date.
