that would be great if it will happend for 4.0.
My bug here acctualy has two sides than. First gcc fails to trace register
value that doesn't change and thus does not require to be cleared on every
loop. Secondly also loop vectorizer fails to produce vector code, but that
wasn't my initial problem anyway, just a second thought.
thanks.
