Other exact width types are optional. 42 * This implementation defines an exact-width types for every integer width 43 * that is represented in the standard integer types. 44 * 45 * The standard also requires minimum-width types be defined for 8-, 16-, 32-, 46 * and 64-bit widths regardless of whether there are corresponding exact-width 47 * types. 48 * 49 * To accomodate targets that are missing types that are exactly 8, 16, 32, or 50 * 64 bits wide, this implementation takes an approach of cascading 51 * redefintions, redefining __int_leastN_t to successively smaller exact-width 52 * types. It is therefore important that the types are defined in order of 53 * descending widths. 54 * 55 * We currently assume that the minimum-width types and the fastest 56 * minimum-width types are the same. This is allowed by the standard, but is 57 * suboptimal. 58 * 59 * In violation of the standard, some targets do not implement a type that is 60 * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit). 61 * To accomodate these targets, a required minimum-width type is only 62 * defined if there exists an exact-width type of equal or greater width. 63 */ 64 65#ifdef __INT64_TYPE__ 66# ifndef __int8_t_defined /* glibc sys/types.h also defines int64_t*/ 67typedef signed __INT64_TYPE__ int64_t;
