------- Comment #3 from rguenth at gcc dot gnu dot org  2008-06-24 12:28 -------
We expand

25        return left << right;

to

        sall    %cl, %ecx

but we initialized %ecx from

        movb    %dl, %cl

so later the comparison against zero fails due to the upper part of ecx
being uninitialized.
