            Bug ID: 102638
           Summary: Add warning for implicit save
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vivekrao4 at yahoo dot com
  Target Milestone: ---

I request that a -Wimplicit-save option be added and made part of -Wall and
-Wextra. Within a procedure, a declaration such as

integer :: i = 0

would trigger the warning. To silence it, the user would have to write

integer, save :: i = 0

Implicit save is a bad feature of Fortran that often surprises and perplexes
newcomers to the language. Gfortran must implement the standard, but it can
nudge users toward better practices with a -Wimplicit-save option.

I meant to say that -Wimplicit-save would be part of -Wall *or* -Wextra.

--- Comment #2 from anlauf at gcc dot gnu.org ---
I am opposed to making this part of -Wall.  This is about standard
conforming code.  If at all, place it under -Wsurprising or -Wextra*.
