557 formal symbol to the f2k_derived namespace.
558 (gfc_match_derived_decl): Register the decl_type_param_list

577 to the structure symbol_attr. Add the 'kind_expr' and
578 'param_list' field to the gfc_component structure. Comment on
579 the reuse of the gfc_actual_arglist structure as storage for
580 type parameter spec lists. Add the new field 'spec_type' to
581 this structure. Add 'param_list' fields to gfc_symbol and
582 gfc_expr. Add prototypes for gfc_insert_kind_parameter_exprs,
583 gfc_insert_parameter_exprs, gfc_add_kind, gfc_add_len,
584 gfc_derived_parameter_expr and gfc_spec_list_type.
585 * interface.c (gfc_compare_derived_types): Treat PDTs in the
586 same way as sequence types.

591 instance.

597 more trailing whitespace to remove.

604 (mio_component): Deal with 'kind_expr' field.
605 (mio_full_f2k_derived): For PDT templates, transfer the formal
606 namespace symroot to the f2k_derived namespace.
607 *primary.c (match_keyword_arg, gfc_match_actual_arglist): Add
608 modifications to handle PDT spec lists. These are flagged in
609 both cases by new boolean arguments, whose prototype defaults
610 are false.
611 (gfc_match_structure_constructor, match_variable): Remove yet
612 more trailing whitespace.
613 * resolve.c (get_pdt_spec_expr, get_pdt_constructor): New
614 functions.
615 (resolve_structure_cons): If the constructor is a PDT template,
616 call get_pdt_constructor to build it using the parameter lists
617 and then get the specific instance of the PDT.
618 (resolve_component): PDT strings need a hidden string length
619 component like deferred characters.
620 (resolve_symbol): Dummy PDTs cannot have deferred parameters.
621 * symbol.c (gfc_add_kind, gfc_add_len): New functions.
622 (free_components): Free 'kind_expr' and 'param_list' fields.
623 (gfc_free_symbol): Free the 'param_list' field.
624 (gfc_find_sym_tree): If the current state is a PDT template,
625 look for the symtree in the f2k_derived namspaces.
626 trans-array.c (structure_alloc_comps): Allocate and deallocate
627 PDTs. Check dummy arguments for compliance of LEN parameters.

632 trans-decl.c (gfc_get_symbol_decl): Call gfc_defer_symbol_init
633 as appropriate for PDT symbols.
634 (gfc_trans_deferred_vars): Allocate/deallocate PDT entities as
635 they come into and out of scope. Exclude pdt_types from being
636 'gcc_unreachable'.
637 (gfc_trans_subcomponent_assign): PDT array components must be
638 handles as if they are allocatable.
639 * trans-stmt.c (gfc_trans_allocate): Handle initialization of
640 PDT entities.
641 (gfc_trans_deallocate): Likewise.
642 * trans-types.c (gfc_get_derived_type): PDT templates must not
643 arrive here. PDT string components are handles as if deferred.
644 Similarly, PDT arrays are treated as if allocatable. PDT
645 strings are pointer types.
646 * trans.c (gfc_deferred_strlen): Handle PDT strings in the same
647 way as deferred characters.
