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: unassig...@gcc.gnu.org
ReportedBy: ja...@gcc.gnu.org
CC: sing...@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.
