69 * The standard requires that exact-width type be defined for 8-, 16-, 32-, and

70 * 64-bit types if they are implemented. Other exact width types are optional.
|

71 * This implementation defines an exact-width types for every integer width
|
|
|
72 * that is represented in the standard integer types.
|
|
|
73 *
|
|
|
74 * The standard also requires minimum-width types be defined for 8-, 16-, 32-,
|
|
|
75 * and 64-bit widths regardless of whether there are corresponding exact-width
|

76 * types.

77 *
|
|
|
78 * To accommodate targets that are missing types that are exactly 8, 16, 32, or

80 * redefinitions, redefining __int_leastN_t to successively smaller exact-width

|

|
83 *
|
|
|
84 * We currently assume that the minimum-width types and the fastest

85 * minimum-width types are the same. This is allowed by the standard, but is
|
|
|
86 * suboptimal.
|
|
|
87 *
|
|
|
88 * In violation of the standard, some targets do not implement a type that is
|
|
|
89 * wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
|
|
|
90 * To accommodate these targets, a required minimum-width type is only
|
|
|
91 * defined if there exists an exact-width type of equal or greater width.

447 * minimum-width) that it defines above, using the limits of the minimum-width

448 * type for any types that do not have exact-width representations.
|
|
|
449 *
|
|
|
450 * As in the type definitions, this section takes an approach of
|
|
|
451 * successive-shrinking to determine which limits to use for the standard (8,
|
|
|
452 * 16, 32, 64) bit widths when they don't have exact representations. It is
|
|
|
453 * therefore important that the definitions be kept in order of decending
|
|
|
454 * widths.
|
|
|
455 *
|
|
|
456 * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the
|
|
|
457 * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
