--- Comment #2 from Qi Feng <ffengqi at gcc dot gnu.org> ---
I tried some modifications in and_comparisons_1 and or_comparisons_1. It seems
that `||' is transformed to `&&' somewhere. And that makes the changes in
or_comparisons_1 noneffective. Should I find the place where the transformation
happens and make changes before that?
