Does it mean that my solution is not accepted? 

If it's so I am going to think about two approaches
    - vectorizer should ignore that path (Richard Biener 2013-09-09 08:22:53

    - replacing the GIMPLE_COND, leading to a block that contains only 
    a call to __builtin_unreachable, with an ASSERT_EXPR, or range information
on this SSA_NAME (now that we store it), or anything without control flow (Marc
