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.
