2279 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
2280 gfc_simplify_minloc to maxloc and minloc, respectively.
2281 * intrinsic.h: Add prototypes for gfc_simplify_minloc
2282 and gfc_simplify_maxloc.
2283 * simplify.c (min_max_chose): Adjust prototype. Modify function
2284 to have a return value which indicates if the extremum was found.
2285 (is_constant_array_expr): Fix typo in comment.
2286 (simplify_minmaxloc_to_scalar): New function.
2287 (simplify_minmaxloc_nodim): New function.
2288 (new_array): New function.
2289 (simplify_minmaxloc_to_array): New function.
2290 (gfc_simplify_minmaxloc): New function.
2291 (simplify_minloc): New function.
2292 (simplify_maxloc): New function.
2294 2018-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
2298 * simplify.c (gfc_simplify_cshift): Re-implement to allow full
2301 2018-01-01 Paul Thomas <pault@gcc.gnu.org>
2304 * resolve.c (resolve_fl_derived0): Add caf_token fields for
2305 allocatable and pointer scalars, when -fcoarray selected.
2306 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
2307 field as well as the backend_decl.
2308 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2309 derived types that are not vtypes. Components with caf_token
2310 attribute are pvoid types. For a component requiring it, find
2311 the caf_token field and have the component token field point to
2315 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2316 field to the descriptor even when codimen not set.
