        * trans-array.c (gfc_trans_create_temp_array): Remove use of the
        function argument. Always generate code for negative extent.
        Simplify said code.
        * trans-array.h (gfc_trans_create_temp_array): Change prototype.
        * trans-expr.c (gfc_conv_function_call): Remove use of last argument
        of gfc_trans_create_temp_array.
        * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Likewise.
        * trans-stmt.c (gfc_conv_elemental_dependencies): Likewise.

        * gfortran.dg/array_function_1.f90: New test.
