2307 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
2308 gfc_simplify_minloc to maxloc and minloc, respectively.
2309 * intrinsic.h: Add prototypes for gfc_simplify_minloc
2310 and gfc_simplify_maxloc.
2311 * simplify.c (min_max_chose): Adjust prototype. Modify function
2312 to have a return value which indicates if the extremum was found.
2313 (is_constant_array_expr): Fix typo in comment.
2314 (simplify_minmaxloc_to_scalar): New function.
2315 (simplify_minmaxloc_nodim): New function.

2335 field as well as the backend_decl.
2336 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
2337 derived types that are not vtypes. Components with caf_token
2338 attribute are pvoid types. For a component requiring it, find
2339 the caf_token field and have the component token field point to
2343 *trans-types.c (gfc_get_array_descriptor_base): Add the token
2344 field to the descriptor even when codimen not set.
