1716 * intrinsic.c (add_function): Add gfc_simplify_maxloc and
1717 gfc_simplify_minloc to maxloc and minloc, respectively.
1718 * intrinsic.h: Add prototypes for gfc_simplify_minloc
1719 and gfc_simplify_maxloc.
1720 * simplify.c (min_max_chose): Adjust prototype. Modify function
1721 to have a return value which indicates if the extremum was found.
1722 (is_constant_array_expr): Fix typo in comment.
1723 (simplify_minmaxloc_to_scalar): New function.
1724 (simplify_minmaxloc_nodim): New function.
1725 (new_array): New function.
1726 (simplify_minmaxloc_to_array): New function.
1727 (gfc_simplify_minmaxloc): New function.
1728 (simplify_minloc): New function.
1729 (simplify_maxloc): New function.
1731 2018-01-02 Thomas Koenig <tkoenig@gcc.gnu.org>
1735 * simplify.c (gfc_simplify_cshift): Re-implement to allow full
1738 2018-01-01 Paul Thomas <pault@gcc.gnu.org>
1741 * resolve.c (resolve_fl_derived0): Add caf_token fields for
1742 allocatable and pointer scalars, when -fcoarray selected.
1743 * trans-types.c (gfc_copy_dt_decls_ifequal): Copy the token
1744 field as well as the backend_decl.
1745 (gfc_get_derived_type): Flag GFC_FCOARRAY_LIB for module
1746 derived types that are not vtypes. Components with caf_token
1747 attribute are pvoid types. For a component requiring it, find
1748 the caf_token field and have the component token field point to
1752 *trans-types.c (gfc_get_array_descriptor_base): Add the token
1753 field to the descriptor even when codimen not set.
