From f9be04cd95886e9e04213131469f9fb2c62a9d87 Mon Sep 17 00:00:00 2001 From: Richard Guenther Date: Mon, 5 Mar 2007 10:57:09 +0000 Subject: [PATCH] re PR tree-optimization/26420 (-ftree-vectorizer-verbose=1 prints unvectorized loops information) 2007-03-05 Richard Guenther Dorit Nuzman PR tree-optimization/26420 * tree-vectorizer.c (vectorize_loops): Bail out early if there are no loops in the function. Only print the number of vectorized loops if it is greater than zero or we are supposed to print information about unvectorized loops.
