--- Comment #11 from Roger Sayle <roger at nextmovesoftware dot com> ---
Mine.  Alas the obvious fix of adding an early clobber to the rotate doubleword
from memory alternative generates some truly terrible code (spills via memory
to SSE registers!?), but I've come up with a better solution, forcing reload to
read the operand from memory before the rotate, which appears to fix the
problem without the adverse performance impact.
