9716         * ipa-icf.c (sem_item_optimizer::sort_congruence_split): New
9717         function.
9718         (sem_item_optimizer::do_congruence_step_f): Sort the congruence
9719         set after UIDs before splitting them.

9724         * gimple-fold.c (get_range_strlen_tree): Record if the computed
9725         length is optimistic.  If it is, then arrange to compute the
9726         conservative length as well.
9727
9728         * gimple-fold.h (get_range_strlen): Update prototype.
9729         * builtins.c (check_access): Update call to get_range_strlen to use
9730         c_strlen_data pointer.   Change various variable accesses to instead
9731         pull data from the c_strlen_data structure.
9732         (check_strncat_sizes, expand_builtin_strncat): Likewise.
9733         * calls.c (maybe_warn_nonstring_arg): Likewise.
9734         * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
9735         minimum length if maximum lengh is unknown.
9736         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
9737         that used c_strlen, it's no longer needed.  Restructure slightly.
9738         (format_string): Set unlikely range appropriately.
9739         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
9740         formatting issues.
9741         (get_range_strlen):  Accept c_strlen_data pointer for external
9742         call sites as well.  Pass through to call to internal get_range_strlen.
9743         Adjust minlen, maxlen and maxbound as needed.
9744         (get_maxval_strlen): Update comments.
9745         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
9746         to use c_strlen_data pointer.  Change variable accesses to instead
9747         use c_strlen_data data members.
9748
9749         * gimple-fold.c (get_range_strlen): Update prototype.
9750         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
9751         local variables.  Use pdata to return information to caller.
9752         Update calls to get_range_strlen.  Update pdata->maxbound.
9753         (get_range_strlen -- static version): Similarly.
9754         (get_range_strlen -- extern version): Update for internal
9755         get_range_strlen API change.  Convert to external data format.
9756         (get_maxval_strlen): Similarly.
