        PR fortran/29821
        * resolve.c (resolve_operator): Only return result of
        gfc_simplify_expr if expression is constant.

        PR fortran/29912
        * trans-expr.c (gfc_trans_arrayfunc_assign): Return NULL if the
        lhs and rhs character lengths are not constant and equal for
        character array valued functions.

        PR fortran/29916
        * resolve.c (resolve_symbol): Allow host-associated variables
        in the specification expression of an array-valued function.
        * expr.c (check_restricted): Accept host-associated dummy
        array indices.

        PR fortran/30003
        * trans-array.c (gfc_trans_create_temp_array): Set the section
        ends to zero.
        (gfc_conv_array_transpose): Likewise.
        (gfc_conv_section_startstride): Declare an expression for end,
        set it from a the array reference and evaluate it for the info
        structure. Zero the ends in the ss structure and set end, used
        in the bounds check, from the info structure.
        trans.h: Add and end array to the gfc_ss_info structure.

        of expected calls of free to 10; the lhs section reference is
        now evaluated so there is another call to bar.  Change the
        comment appropriately.
