79  *
80  * The standard requires that exact-width type be defined for 8-, 16-, 32-, and
81  * 64-bit types if they are implemented. Other exact width types are optional.
82  * This implementation defines an exact-width types for every integer width
83  * that is represented in the standard integer types.
84  *
85  * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
86  * and 64-bit widths regardless of whether there are corresponding exact-width
87  * types.
88  *
89  * To accommodate targets that are missing types that are exactly 8, 16, 32, or
90  * 64 bits wide, this implementation takes an approach of cascading
91  * redefintions, redefining __int_leastN_t to successively smaller exact-width
92  * types. It is therefore important that the types are defined in order of
93  * descending widths.
94  *
95  * We currently assume that the minimum-width types and the fastest
96  * minimum-width types are the same. This is allowed by the standard, but is
97  * suboptimal.
98  *
99  * In violation of the standard, some targets do not implement a type that is
100  * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
101  * To accommodate these targets, a required minimum-width type is only
102  * defined if there exists an exact-width type of equal or greater width.

452 /* C99 7.18.2.1 Limits of exact-width integer types.
453  * C99 7.18.2.2 Limits of minimum-width integer types.
454  * C99 7.18.2.3 Limits of fastest minimum-width integer types.
455  *
456  * The presence of limit macros are completely optional in C99. This
457  * implementation defines limits for all of the types (exact- and
458  * minimum-width) that it defines above, using the limits of the minimum-width
459  * type for any types that do not have exact-width representations.
460  *
461  * As in the type definitions, this section takes an approach of
462  * successive-shrinking to determine which limits to use for the standard (8,
463  * 16, 32, 64) bit widths when they don't have exact representations. It is
464  * therefore important that the defintions be kept in order of decending
465  * widths.
466  *
467  * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the
468  * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
