9787 * gimple-fold.c (get_range_strlen_tree): Record if the computed
9788 length is optimistic. If it is, then arrange to compute the
9789 conservative length as well.
9791 * gimple-fold.h (get_range_strlen): Update prototype.
9792 * builtins.c (check_access): Update call to get_range_strlen to use
9793 c_strlen_data pointer. Change various variable accesses to instead
9794 pull data from the c_strlen_data structure.

9798 minimum length if maximum lengh is unknown.
9799 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
9800 that used c_strlen, it's no longer needed. Restructure slightly.
9801 (format_string): Set unlikely range appropriately.
9802 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
9804 (get_range_strlen): Accept c_strlen_data pointer for external
9805 call sites as well. Pass through to call to internal get_range_strlen.
9806 Adjust minlen, maxlen and maxbound as needed.
9807 (get_maxval_strlen): Update comments.
