------- Comment #3 from burnus at gcc dot gnu dot org 2008-07-23 16:12 ------- Test case for the run-time check. Only for the second call a warning is needed. One way to add it is the following. One simply inserts
if (parm.1.data != D.1036) printf("test.f90:5: In call to FOO, an array temporary " "was created for argument #1\n"); between the following lines: D.1036 = _gfortran_internal_pack (&parm.1); foo (D.1036); (The "if" line is copied from the _gfortran_internal_unpack block.) Test case: program test implicit none integer :: a(3,3) call foo(a(:,1)) ! OK, no temporary created call foo(a(1,:)) ! BAD, temporary var created contains subroutine foo(x) integer :: x(3) x = 5 end subroutine foo end program test -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29952
