Hi,
I was testing i386-rtems4.10 and 225
tests failed on the target because it
does not have any SSE flavor. It is

A while back, some tests had run-time
checks added to ensure they were on a
CPU with the proper support. Are these
tests doing that or is there another
issue?
They do it via sse2-check.h and cpuid.h. Try to figure out why
that doesn't work for your CPU (which is ...?)
qemu with no cpu argument specified. So qemu32.
It does run OK when I change the cpu model to 486
or pentium.
cpu_id returns this for the qemu32 cpu model (test fails)
a=0x633 b=0x800 c=0x1 d=0x781abfd
this for the 486 model (test works)
a=0x0 b=0x0 c=0x0 d=0x0
this for pentium (test works)
a=0x543 b=0x800 c=0x0 d=0x8001bf
and this for "coreduo" (test fails)
a=0x6e8 b=0x800 c=0x9 d=0x789fbff
Is qemu reporting that it supports SSE and not doing a good
enough job to make gcc happen?
