66 * C99 7.18.1.2 Minimum-width integer types.
67 * C99 7.18.1.3 Fastest minimum-width integer types.
68 *
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
79 * 64 bits wide, this implementation takes an approach of cascading
80 * redefinitions, redefining __int_leastN_t to successively smaller exact-width
81 * types. It is therefore important that the types are defined in order of
82 * descending widths.
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.
