From d74ee1050558fc583b90b340eafef3ca861bad95 Mon Sep 17 00:00:00 2001 From: rguenth Date: Mon, 5 Mar 2007 10:57:09 +0000 Subject: 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@122544 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-vectorizer.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'gcc/tree-vectorizer.c') diff --git a/gcc/tree-vectorizer.c b/gcc/tree-vectorizer.c index 2a53b9c9fa3..b0aedf74b2c 100644 --- a/gcc/tree-vectorizer.c +++ b/gcc/tree-vectorizer.c @@ -2196,6 +2196,12 @@ vectorize_loops (void) loop_iterator li; struct loop *loop; + vect_loops_num = number_of_loops (); + + /* Bail out if there are no loops. */ + if (vect_loops_num <= 1) + return 0; + /* Fix the verbosity level if not defined explicitly by the user. */ vect_set_dump_settings (); @@ -2208,7 +2214,6 @@ vectorize_loops (void) /* If some loop was duplicated, it gets bigger number than all previously defined loops.
