             Bug #: 50036
           Summary: g++.dg/tree-prof/tree-prof.exp doesn't work correctly
    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


g++.dg/tree-prof/tree-prof.exp has

# Override the list defined in profopt.exp.
set PROFOPT_OPTIONS [list {}]

However, I got

-Os isn't supposed to run on g++.dg/tree-prof/partition2.C.
But tree-prof.exp uses profopt-execute from bprob.exp which
was run first.
