2280 Update copyright years.
2282 * gfortranspec.c (lang_specific_driver): Update copyright notice
2284 * gfc-internals.texi: Bump @copying's copyright year.

2289 2017-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
2292 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
2293 gfc_simplify_minloc to maxloc and minloc, respectively.
2294 * intrinsic.h: Add prototypes for gfc_simplify_minloc
2295 and gfc_simplify_maxloc.
2296 * simplify.c (min_max_chose): Adjust prototype. Modify function
2297 to have a return value which indicates if the extremum was found.
2298 (is_constant_array_expr): Fix typo in comment.
2299 (simplify_minmaxloc_to_scalar): New function.
2300 (simplify_minmaxloc_nodim): New function.
2301 (new_array): New function.
2302 (simplify_minmaxloc_to_array): New function.
2303 (gfc_simplify_minmaxloc): New function.
2304 (simplify_minloc): New function.
2305 (simplify_maxloc): New function.
2307 2018-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>

2317 * resolve.c (resolve_fl_derived0): Add caf_token fields for
2318 allocatable and pointer scalars, when -fcoarray selected.

2320 field as well as the backend_decl.
2321 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2322 derived types that are not vtypes. Components with caf_token
2323 attribute are pvoid types. For a component requiring it, find
2324 the caf_token field and have the component token field point to
2328 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2329 field to the descriptor even when codimen not set.
