195 * The "i64" shift counts have been decreased by 16 (decimal) in order to
196 * test negative values as well. Finally, the full list of QemuOpt elements
197 * has been permuted with "shuf".
198 *
199 * Both "i64" and "u64" have some (distinct) single-element ranges
200 * represented as both "a" and "a-a". "u16" is a special case of "i64" (see
201 * visit_type_uint16()), so it wouldn't add a separate test in this regard.
