11198         (get_range_strlen):  Accept c_strlen_data pointer for external
11199         call sites as well.  Pass through to call to internal get_range_strlen.
11200         Adjust minlen, maxlen and maxbound as needed.
11201         (get_maxval_strlen): Update comments.
11202         (gimple_fold_builtin_strlen):  Update call to get_range_strlen
11203         to use c_strlen_data pointer.  Change variable accesses to instead
11204         use c_strlen_data data members.
11205
11206         * gimple-fold.c (get_range_strlen): Update prototype.
11207         (get_range_strlen_tree): Update prototype.  Drop minlen/maxlen
11208         local variables.  Use pdata to return information to caller.
11209         Update calls to get_range_strlen.  Update pdata->maxbound.
11210         (get_range_strlen -- static version): Similarly.
11211         (get_range_strlen -- extern version): Update for internal
11212         get_range_strlen API change.  Convert to external data format.
11213         (get_maxval_strlen): Similarly.
