             Bug #: 55995
           Summary: vect increase_alignment notes missing from dump file
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: janis@gcc.gnu.org
                CC: singhai@gcc.gnu.org
            Target: arm*-*-* powerpc*-*-*


Test gcc.dg/vect/aligned-section-anchors-nest-1.c started failing with the
patch added in revisions 191883 and 191884 that changes the verbosity of
compiler dump files.  The dump file scan is for a file created with
-fdump-ipa-increase-alignment and a message output with MSG_NOTE.  Unlike
-fdump-tree-switch-options, there is apparently no support for
-fdump-ipa-switch-options and I couldn't figure out how to get the notes
included in the increase_alignment dump file.

The messages are output from function increase_alignment in tree-vectorizer.c.

The test is run for effective targets section_anchors and vect_int, which
includes powerpc*-*-* and arm*-*-*.

The test was added in 2009 so this is a regression.
