           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.

I can confirm this on i686-unknown-openbsd3.1 and it is caused by Keating's intermoduler 
complication because if I revert just that the tests in the testcases (for -fprofile-arcs) passes.

Assigning to Geoff Keating who's patch:

        && MAIN_NAME_P (DECL_NAME (fndecl))

      expand_main_function ();

    /* Generate the RTL for this function.  */

      expand_main_function ();

    /* Generate the RTL for this function.  */


Fixes it on i686-openbsd3.1 at least, most likely fixes it in cygwin also.

Can you try again now this patch went in?

Since I don't have CVS access at this site, I manually applied this patch to the
July 23rd Mainline snapshot on pentium4-pc-cygwin.  

.gcda files are now created with -fprofile-arcs.

It corrects all of the bprob-* and gcov-* testcases which were previously failing. 

It also allows make profiledbootstrap to procede much farther than before.

Therefore, I think this particular bug can be closed.

However, make profiledbootstraps still fails thought for a new reason, I'll try
to do some diagnosing and open a new bug with some details.

Thanks for the feedback. Closing as suggested.
Also sometimes using --disable-werror will fix profiledbootstrap.
