Richard Guenther f9be04cd95 re PR tree-optimization/26420 (-ftree-vectorizer-verbose=1 prints unvectorized loops information) 
2007-03-05  Richard Guenther  <rguenther@suse.de>

	PR tree-optimization/26420

	are no loops in the function.  Only print the number of

	to print information about unvectorized loops.
