9127         function.

9134         * gimple-fold.c (get_range_strlen_tree): Record if the computed
9135         length is optimistic.  If it is, then arrange to compute the
9136         conservative length as well.
9137
9138         * gimple-fold.h (get_range_strlen): Update prototype.
9139         * builtins.c (check_access): Update call to get_range_strlen to use
9140         c_strlen_data pointer.   Change various variable accesses to instead
9141         pull data from the c_strlen_data structure.
9142         (check_strncat_sizes, expand_builtin_strncat): Likewise.
9143         * calls.c (maybe_warn_nonstring_arg): Likewise.
9144         * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise.  Reset
9145         minimum length if maximum lengh is unknown.
9146         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
9147         that used c_strlen, it's no longer needed.  Restructure slightly.
9148         (format_string): Set unlikely range appropriately.
9149         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
9150         formatting issues.
9151         (get_range_strlen):  Accept c_strlen_data pointer for external
9152         call sites as well.  Pass through to call to internal get_range_strlen.
9153         Adjust minlen, maxlen and maxbound as needed.
9154         (get_maxval_strlen): Update comments.
9155         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
9156         to use c_strlen_data pointer.  Change variable accesses to instead
9157         use c_strlen_data data members.
9158
9159         * gimple-fold.c (get_range_strlen): Update prototype.
9160         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
9161         local variables.  Use pdata to return information to caller.
9162         Update calls to get_range_strlen.  Update pdata->maxbound.
9163         (get_range_strlen -- static version): Similarly.
9164         (get_range_strlen -- extern version): Update for internal
9165         get_range_strlen API change.  Convert to external data format.
9166         (get_maxval_strlen): Similarly.
