11192         (get_range_strlen):  Accept c_strlen_data pointer for external
11193         call sites as well.  Pass through to call to internal get_range_strlen.
11194         Adjust minlen, maxlen and maxbound as needed.
11195         (get_maxval_strlen): Update comments.
11196         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
11197         to use c_strlen_data pointer.  Change variable accesses to instead
11198         use c_strlen_data data members.
11199
11200         * gimple-fold.c (get_range_strlen): Update prototype.
11201         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
11202         local variables.  Use pdata to return information to caller.
11203         Update calls to get_range_strlen.  Update pdata->maxbound.
11204         (get_range_strlen -- static version): Similarly.
11205         (get_range_strlen -- extern version): Update for internal
11206         get_range_strlen API change.  Convert to external data format.
11207         (get_maxval_strlen): Similarly.
