Hi Janne,
I think, in general, our current system where
-std=gnu means roughly "everything we have implemented so far, except
legacy extensions that break standards conformance" is pretty good.
The problem that I see with implementing this change is stack space,
especially the traditionally li

Hi Janne,
I think you need a few more test cases, like (compile with -fcheck=all
and -std=f2018):
module foo
contains
subroutine f(n)
call g(n-1)
end subroutine f
subroutine g(n)
if (n<0) return
call f(n-1)
end subroutine g
end module foo
program main
use foo
call f(10)

Fortran 2018 makes procedures recursive by default (effectively making
the existing RECURSIVE attribute a no-op). Instead it adds a
NON_RECURSIVE attribute that a programmer can use to mark a procedure
that may not be called recursively. This patch adds support for that.
