2277 * simplify.c (gfc_simplify_cshift): Re-implement to allow full
2280 2018-01-01 Paul Thomas <pault@gcc.gnu.org>
2283 * resolve.c (resolve_fl_derived0): Add caf_token fields for
2284 allocatable and pointer scalars, when -fcoarray selected.
2285 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
2286 field as well as the backend_decl.
2287 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2288 derived types that are not vtypes. Components with caf_token
2289 attribute are pvoid types. For a component requiring it, find
2290 the caf_token field and have the component token field point to
2294 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2295 field to the descriptor even when codimen not set.
