2273 Update copyright years.
2275 * gfortranspec.c (lang_specific_driver): Update copyright notice
2277 * gfc-internals.texi: Bump @copying's copyright year.

2279 * intrinsic.texi: Ditto.
2280 * invoke.texi: Ditto.
2282 2017-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
2285 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
2286 gfc_simplify_minloc to maxloc and minloc, respectively.
2287 * intrinsic.h: Add prototypes for gfc_simplify_minloc
2288 and gfc_simplify_maxloc.
2289 * simplify.c (min_max_chose): Adjust prototype. Modify function
2290 to have a return value which indicates if the extremum was found.

2295 (simplify_minmaxloc_to_array): New function.
2296 (gfc_simplify_minmaxloc): New function.
2297 (simplify_minloc): New function.
2298 (simplify_maxloc): New function.

2307 2018-01-01 Paul Thomas <pault@gcc.gnu.org>
2310 * resolve.c (resolve_fl_derived0): Add caf_token fields for
2311 allocatable and pointer scalars, when -fcoarray selected.

2313 field as well as the backend_decl.
2314 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2315 derived types that are not vtypes. Components with caf_token
2316 attribute are pvoid types. For a component requiring it, find
2317 the caf_token field and have the component token field point to
2321 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2322 field to the descriptor even when codimen not set.
