--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
So it's only because the incoming x is sign-extended to long due to the ABI?
Seems to be a quite "localized" issue. Btw, it was ppc folks requesting this
pattern as a building block for a larger transform.
It's always difficult to use canonicalizations to do simplifications.
