10295         minimum length if maximum lengh is unknown.
10296         * gimple-ssa-sprintf.c (get_string_length): Likewise.  Drop code
10297         that used c_strlen, it's no longer needed.  Restructure slightly.
10298         (format_string): Set unlikely range appropriately.
10299         * gimple-fold.c (get_range_strlen): Update comments.  Fix minor
10300         formatting issues.
10301         (get_range_strlen):  Accept c_strlen_data pointer for external
10302         call sites as well.  Pass through to call to internal get_range_strlen.
10303         Adjust minlen, maxlen and maxbound as needed.
10304         (get_maxval_strlen): Update comments.
10305         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
10306         to use c_strlen_data pointer.  Change variable accesses to instead
10307         use c_strlen_data data members.
10308
10309         * gimple-fold.c (get_range_strlen): Update prototype.
10310         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
10311         local variables.  Use pdata to return information to caller.
10312         Update calls to get_range_strlen.  Update pdata->maxbound.
10313         (get_range_strlen -- static version): Similarly.
10314         (get_range_strlen -- extern version): Update for internal
10315         get_range_strlen API change.  Convert to external data format.
10316         (get_maxval_strlen): Similarly.
