2007-10-02 Paul Thomas <pault@gcc.gnu.org> PR fortran/31154 PR fortran/31229 PR fortran/33334 * decl.c : Declare gfc_function_kind_locs and gfc_function_type_locus. (gfc_match_kind_spec): Add second argument kind_expr_only. Store locus before trying to match the expression. If the current state corresponds to a function declaration and there is no match to the expression, read to the parenthesis, return kind = -1, dump the expression and return. (gfc_match_type_spec): Renamed from match_type_spec and all references changed. If an interface or an external function, store the locus, set kind = -1 and return. Otherwise, if kind is already = -1, use gfc_find_symbol to try to find a use associated or imported type. match.h : Prototype for gfc_match_type_spec. * parse.c (match_deferred_characteristics): New function. (parse_spec): If in a function, statement is USE or IMPORT or DERIVED_DECL and the function kind=-1, call match_deferred_characteristics. If kind=-1 at the end of the specification expressions, this is an error. * parse.h : Declare external gfc_function_kind_locs and gfc_function_type_locus. 2007-10-02 Paul Thomas <pault@gcc.gnu.org> PR fortran/31154 PR fortran/31229 PR fortran/33334 * gfortran.dg/function_kinds_1.f90: New test. * gfortran.dg/function_kinds_2.f90: New test. * gfortran.dg/derived_function_interface_1.f90: Correct illegal use association into interfaces.
