cvttps2dq is 0x5b(b=0x5b) with repn
It appears that cvttps2dq is indeed the only exception in the range,
combined patch that fixes both movd?q2d?q and cvttps2dq is attached.
I don't have any kind of SSE on this machine so would apprecaite if
someone would run tests/test-i386 with the patch attached.
That works for me.
The SSE2 instructions cvttps2dq, movdq2q, movq2dq do not behave
correctly, as shown by the attached program. It should print
cvttps2dq_1 ... ok
cvttps2dq_2 ... ok
movdq2q_1 ... ok
movq2dq_1 ... ok
but instead produces
cvttps2dq_1 ... ok
cvttps2dq_2 ... not ok

The signature of movdq2q is Pq, VRq and for movq2dq - Vo, PRq it appears
that translate.c gets it backwards, attached patch should deal with it.
Cool.
As for cvttps2dq i ran it with interpreter which uses outdated(i.e. non
soft-float) conversion

Running it on a CPU without SSE2, if i'm allowed to venture a gues.

Yup. Try 'strace ./sse2test' and see if it gets SIGILLs thrown at it.

You are right, I get SIGILLs.
Seems I was wrong thinking Athlon xp was able to support sse2.
