re PR middle-end/41453 (use INTENT(out) for optimization)
2018-09-22 Thomas Koenig <tkoenig@gcc.gnu.org>
PR fortran/41453
* trans.h (gfc_conv_expr_reference): Add optional argument
add_clobber to prototype.
(gfc_conv_procedure_call): Set add_clobber argument to
gfc_conv_procedure_reference to true for scalar, INTENT(OUT),
non-pointer, non-allocatable, non-dummy variables whose type
is neither BT_CHARACTER, BT_DERIVED or BT_CLASS, but only if
the procedure is not elemental.
* trans-expr.c (gfc_conv_procedure_reference): Add clobber
statement before call if add_clobber is set.

* gfortran.dg/intent_optimize_2.f90: New test.
