PLEASE REPLY TO gcc-bugzilla@gcc.gnu.org ONLY, *NOT* gcc-bugs@gcc.gnu.org.

           Summary: [3.4 regression] -fprofile-arcs no longer creates
                    {.da,.gcda} files
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: kelleycook at wideopenwest dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-cygwin
  GCC host triplet: i686-pc-cygwin
GCC target triplet: i686-pc-cygwin

As shown in testsuite runs,

-fprofile-arcs no longer creates the *.da (though based on the testsuite, I'm
assuming that these were recently renamed to *.gcra) which are used for
-fbranch-probabilities.

This feature works fine under cygwin in 3.3.

In addition, a profiledbootstrap now fails for the exact same reason, this was
working until recently.
