Summary: Wrong "unused parameter" warning with interface block
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: enhancement
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: tkoenig@gcc.gnu.org
Original test case by Ondrej Certik from
http://gcc.gnu.org/ml/fortran/2011-04/msg00297.html
Reduced test case:
module foo
contains
function f(g)
interface
real function g()
end function g
end interface
real :: f
f = g()
end function f
end module foo
ig25@linux-fd1f:~/Krempel/Warn> gfortran -c -Wunused-parameter b.f90
b.f90:3:0: warning: unused parameter 'g' [-Wunused-parameter]
Same warning in 4.4, so probably not a regression.

--- Comment #2 from Thomas Koenig <tkoenig at gcc dot gnu.org> 2012-02-03 22:13:07 UTC ---
This doesn't match the docs. We say
-Wunused-parameter'
Contrary to `gcc''s meaning of `-Wunused-parameter', `gfortran''s
implementation of this option does not warn about unused dummy
arguments (see `-Wunused-dummy-argument'), but about unused
`PARAMETER' values. `-Wunused-parameter' is not included in
`-Wall' but is implied by `-Wall -Wextra'.
-Wunsued-parameter is being used in the C sense here.
We don't warn with
ig25@linux-fd1f:~/Krempel/Unused> cat bar.f90
module foo
contains
function f(g)
f = g()
end function f
end module foo
ig25@linux-fd1f:~/Krempel/Unused> gfortran -S -Wunused-dummy-argument bar.f90
(and we should).
