re PR fortran/45516 ([F08] allocatable compontents of recursive type)
2016-10-25 Paul Thomas <pault@gcc.gnu.org>
PR fortran/45516
* class.c (gfc_find_derived_vtab): Detect recursive allocatable
derived type components. If present, add '_deallocate' field to
the vtable and build the '__deallocate' function.
* decl.c (build_struct): Allow recursive allocatable derived
type components for -std=f2008 or more.
(gfc_match_data_decl): Accept these derived types.
* expr.c (gfc_has_default_initializer): Ditto.
* resolve.c (resolve_component): Make sure that the vtable is
built for these derived types.
* trans-array.c(structure_alloc_comps) : Use the '__deallocate'
function for the automatic deallocation of these types.
* trans-expr.c : Generate the deallocate accessor.
* trans.h : Add its prototype.
* trans-types.c (gfc_get_derived_type): Treat the recursive
allocatable components in the same way as the corresponding
pointer components.
