2289 Update copyright years.
2291 * gfortranspec.c (lang_specific_driver): Update copyright notice
2293 * gfc-internals.texi: Bump @copying's copyright year.

2296 * invoke.texi: Ditto.
2298 2017-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
2301 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
2302 gfc_simplify_minloc to maxloc and minloc, respectively.
2303 * intrinsic.h: Add prototypes for gfc_simplify_minloc
2304 and gfc_simplify_maxloc.
2305 * simplify.c (min_max_chose): Adjust prototype. Modify function
2306 to have a return value which indicates if the extremum was found.
2307 (is_constant_array_expr): Fix typo in comment.
2308 (simplify_minmaxloc_to_scalar): New function.
2309 (simplify_minmaxloc_nodim): New function.
2310 (new_array): New function.
2311 (simplify_minmaxloc_to_array): New function.
2312 (gfc_simplify_minmaxloc): New function.
2313 (simplify_minloc): New function.
2314 (simplify_maxloc): New function.
2316 2018-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>

2326 * resolve.c (resolve_fl_derived0): Add caf_token fields for
2327 allocatable and pointer scalars, when -fcoarray selected.
2328 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
2329 field as well as the backend_decl.
2330 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2331 derived types that are not vtypes. Components with caf_token
2332 attribute are pvoid types. For a component requiring it, find
2333 the caf_token field and have the component token field point to
2337 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2338 field to the descriptor even when codimen not set.
