           Summary: DSYMUTIL_SPEC doesn't handle -gtoggle
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: howarth@nitro.med.uc.edu


Currently on darwin, DSYMUTIL_SPEC is unaware of the -gtoggle flag. This
results in dsymutil not being called as expected when '-g0 -gtoggle' is passed
to the compiler despite any resulting object files containing the expected
DWARF debug information. It is unclear how we can code for this in
DSYMUTIL_SPEC since -gtoggle needs to invert the final accumulative setting of
-g.
