[Bug tree-optimization/26420] -ftree-vectorizer-verbose=1 prints unvectorized loops information

["dorit at il dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from dorit at il dot ibm dot com  2006-02-26 11:01 -------
For -ftree-vectorizer-verbose=1 the vectorizer reports each loop that got
vectorized, and also the total number of loops that got vectorized, even if
that number is zero. If preferable, we can report that 0 loops got vectorized
only under -ftree-vectorizer-verbose=2, or higher. The patch below makes the
"vectorized 0 loops" be reported for verbosity level 2 and higher. Shall I
suggest the patch for mainline?
