ICC compiles my testsuite into:
t1:
.B1.1:                          # Preds .B1.0
        pushl     %ebx                                          #15.1
        movl      %esp, %ebx
        andl      $-16, %esp
        pand      %xmm1, %xmm0
        movl      %ebx, %esp
        popl      %ebx
        ret

Looks like register passing convention :)

Yes, sorry for that.
There is also bug in the fabs patch, I will send updated version of that
one.
