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.
