1160 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
1161 gfc_simplify_minloc to maxloc and minloc, respectively.
1162 * intrinsic.h: Add prototypes for gfc_simplify_minloc
1163 and gfc_simplify_maxloc.
1164 * simplify.c (min_max_chose): Adjust prototype. Modify function
1165 to have a return value which indicates if the extremum was found.
1166 (is_constant_array_expr): Fix typo in comment.
1167 (simplify_minmaxloc_to_scalar): New function.
1168 (simplify_minmaxloc_nodim): New function.
1169 (new_array): New function.
1170 (simplify_minmaxloc_to_array): New function.
1171 (gfc_simplify_minmaxloc): New function.
1172 (simplify_minloc): New function.
1173 (simplify_maxloc): New function.
1175 2018-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
1179 * simplify.c (gfc_simplify_cshift): Re-implement to allow full
1182 2018-01-01 Paul Thomas <pault@gcc.gnu.org>
1185 * resolve.c (resolve_fl_derived0): Add caf_token fields for
1186 allocatable and pointer scalars, when -fcoarray selected.
1187 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
1188 field as well as the backend_decl.
1189 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
1190 derived types that are not vtypes. Components with caf_token
1191 attribute are pvoid types. For a component requiring it, find
1192 the caf_token field and have the component token field point to
1196 *trans-types.c (gfc_get_array_descriptor_base): Add the token
1197 field to the descriptor even when codimen not set.
