/* C99 7.18.1.1 Exact-width integer types.
16
 * C99 7.18.1.2 Minimum-width integer types.
17
 * C99 7.18.1.3 Fastest minimum-width integer types.
18
 *
19
 * The standard requires that exact-width type be defined for 8-, 16-, 32-, and
20
 * 64-bit types if they are implemented. Other exact width types are optional.
21
 * This implementation defines an exact-width types for every integer width
22
 * that is represented in the standard integer types.
23
 *
24
 * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
25
 * and 64-bit widths regardless of whether there are corresponding exact-width
26
 * types.
27
 *
28
 * To accommodate targets that are missing types that are exactly 8, 16, 32, or
29
 * 64 bits wide, this implementation takes an approach of cascading
30
 * redefinitions, redefining __int_leastN_t to successively smaller exact-width
31
 * types. It is therefore important that the types are defined in order of
32
 * descending widths.
33
 *
34
 * We currently assume that the minimum-width types and the fastest
35
 * minimum-width types are the same. This is allowed by the standard, but is
36
 * suboptimal.
37
 *
38
 * In violation of the standard, some targets do not implement a type that is
39
 * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
40
 * To accommodate these targets, a required minimum-width type is only
41
 * defined if there exists an exact-width type of equal or greater width.

 * minimum-width types defined above. As 8-, 16-, 32-, and 64-bit minimum-width
257
 * types are required, the corresponding integer constant macros are defined

 * here. This implementation also defines minimum-width types for every other
259
 * integer width that the target implements, so corresponding macros are
260
 * defined below, too.
261
 *
262
 * These macros are defined using the same successive-shrinking approach as
263
 * the type definitions above. It is likewise important that macros are defined
264
 * in order of decending width.
265
 *
266
 * Note that C++ should not check __STDC_CONSTANT_MACROS here, contrary to the
267
 * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).

 * implementation defines limits for all of the types (exact- and
422
 * minimum-width) that it defines above, using the limits of the minimum-width
423
 * type for any types that do not have exact-width representations.
424
 *
425
 * As in the type definitions, this section takes an approach of
426
 * successive-shrinking to determine which limits to use for the standard (8,
427
 * 16, 32, 64) bit widths when they don't have exact representations. It is
428
 * therefore important that the definitions be kept in order of decending
429
 * widths.
430
 *
431
 * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the
432
 * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
