1007 try again, allowing a proc pointer selector.
1012 * primary.c (gfc_match_varspec): Introduce 'tgt_expr', which
1013 points to the associate selector, if any. Go through selector
1014 references, after resolution for variables, to catch any full

1078 namespace since they are instantiated in the template ns.

2231 * trans-array.h: Change prototype of gfc_nullify_alloc_comp ().
2232 * trans-decl.c (generate_coarray_sym_init): Call nullify_alloc_comp for
2233 derived type coarrays with pointer components.
2234 * trans-expr.c (gfc_trans_structure_assign): Also treat pointer
2236 (trans_caf_token_assign): Handle assignment of token of scalar pointer
2238 (gfc_trans_pointer_assignment): Call above routine.

2244 a coarray pre-register the tokens.
2245 (gfc_trans_deallocate): Simply determining the coarray type (scalar or
2246 array) and deregistering it correctly.
2247 * trans-types.c (gfc_typenode_for_spec): Replace in_coarray flag by the
2248 actual codim to allow lookup of array types in the cache.
2249 (gfc_build_array_type): Likewise.
2250 (gfc_get_array_descriptor_base): Likewise.
2251 (gfc_get_array_type_bounds): Likewise.

2253 * trans-types.h: Likewise.
2254 * trans.c (gfc_deallocate_with_status): Enable deregistering of all kind
2255 of coarray components.
2256 (gfc_deallocate_scalar_with_status): Use free() in fcoarray_single mode
2257 instead of caf_deregister.

2263 #pragma GCC diagnostic {push,ignored,pop}.
2265 2017-01-06 Alexandre Oliva <aoliva@redhat.com>
2267 * simplify.c (simplify_transformation_to_array): Silence
2268 array bounds warning. Fix whitespace.

2272 * module.c (load_omp_udrs): Initialize name.
2274 2017-01-02 Janne Blomqvist <jb@gcc.gnu.org>
2277 * trans-expr.c (gfc_trans_string_copy): Rework string copy
2278 algorithm to avoid -Wstringop-overflow warning.
