1722 Update copyright years.
1724 * gfortranspec.c (lang_specific_driver): Update copyright notice
1726 * gfc-internals.texi: Bump @copying's copyright year.

1728 * intrinsic.texi: Ditto.
1729 * invoke.texi: Ditto.
1731 2017-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
1734 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
1735 gfc_simplify_minloc to maxloc and minloc, respectively.
1736 * intrinsic.h: Add prototypes for gfc_simplify_minloc
1737 and gfc_simplify_maxloc.
1738 * simplify.c (min_max_chose): Adjust prototype. Modify function
1739 to have a return value which indicates if the extremum was found.
1740 (is_constant_array_expr): Fix typo in comment.
1741 (simplify_minmaxloc_to_scalar): New function.
1742 (simplify_minmaxloc_nodim): New function.
1743 (new_array): New function.
1744 (simplify_minmaxloc_to_array): New function.
1745 (gfc_simplify_minmaxloc): New function.
1746 (simplify_minloc): New function.
1747 (simplify_maxloc): New function.

1759 * resolve.c (resolve_fl_derived0): Add caf_token fields for
1760 allocatable and pointer scalars, when -fcoarray selected.
1761 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
1762 field as well as the backend_decl.
1763 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
1764 derived types that are not vtypes. Components with caf_token
1765 attribute are pvoid types. For a component requiring it, find
1766 the caf_token field and have the component token field point to
1770 *trans-types.c (gfc_get_array_descriptor_base): Add the token
1771 field to the descriptor even when codimen not set.
