             Bug #: 51128
           Summary: [4.7 Regression] New LTO failures
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com


Many LTO tests failed:

with

gcc.dg/torture/pr39074-2.c  -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects
: dump file does not exist
UNRESOLVED: gcc.dg/torture/pr39074-2.c  -O2 -flto -fuse-linker-plugin
-fno-fat-lto-objects  scan-tree-dump alias "y.._., points-to vars: { i }"

since -fno-fat-lto-objects turns off those tree optimizations.

A better fix is outlined in my comment to the original post of this patch at
<http://gcc.gnu.org/ml/gcc-patches/2011-10/msg01998.html>, with "my patch"
referring to <http://gcc.gnu.org/ml/gcc-patches/2011-10/msg01917.html> (since
long committed).
