------- Comment #3 from pinskia at gcc dot gnu dot org  2005-12-28 16:30 -------
Confirmed, just a missing XFAIL as we have unsigned char + unsigned char which
gets changed to (int)(unsigned char)+(int)(unsigned char) after Kazu's patch:
2005-12-26  Kazu Hirata  <kazu@codesourcery.com>

        PR tree-optimization/25125
        * convert.c (convert_to_integer): Don't narrow the type of a
        PLUX_EXPR or MINUS_EXPR if !flag_wrapv and the unwidened type
        is signed.

------- Comment #6 from dorit at il dot ibm dot com  2006-01-04 07:33 -------
Maybe related to:

2005-12-26  Kazu Hirata  <kazu@codesourcery.com>

        PR tree-optimization/25125
        * convert.c (convert_to_integer): Don't narrow the type of a
        PLUX_EXPR or MINUS_EXPR if !flag_wrapv and the unwidened type
        is signed.

(indeed this testcase fails vectorization due to cast to unsigned char).
If that's the case, it should probably be xfailed and the PR should be "missed
optimization"
