            Bug ID: 60504
           Summary: [4.9 regression] many Ada testsuite regressions with
                    gcc-4.9-20140309 on armv5tel-linux-gnueabi
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mikpelinux at gmail dot com

With gcc-4.9-20140309 I see the following testsuite regressions on
armv5tel-linux-gnueabi compared to the previous working snapshot
gcc-4.9-20140223 (the intermediate 4.9-20130302 didn't bootstrap due to
PR60411):

I kind of suspect the ARM unwinder changes, but I haven't had time to verify
that.
