           Summary: Implement -f(no-)frontend-optimization
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassig...@gcc.gnu.org

As proposed by Joost:

Having some option, for instance -f(no-)frontend-optimization, to
disable/enable the front-end optimization.

That allows FE optimization with -O0, e.g. for LTO or debugging.
Or to disable it for -O1/-O2/-O3 for debugging or testing.
