------- Comment #6 from suckfish at ihug dot co dot nz  2008-10-17 22:18 -------
Pleasantly, my fears that this was just the tip of the iceburg seems to be
wrong.  Writing some test cases, found another bug involving a shift, and also
the ICE below [fixed by some combination of change above and 38707 fix.]

Will fix the remaining case & post patches to gcc-patches list.

#include <mmintrin.h>
typedef int v2si __attribute__ ((vector_size (8)));
v2si shiftU (v2si y)
{
    return _m_psrldi (_m_psrldi (y, 0), 0);
}

$ gcc -O shift2.c
shift2.c: In function ‘shiftU’:
shift2.c:6: internal compiler error: in trunc_int_for_mode, at explow.c:55
