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.

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). ^ permalink raw reply [flat|nested] 6+ messages in thread
