* C99 7.18.1.3 Fastest minimum-width integer types.
|
|
*
|
|
* The standard requires that exact-width type be defined for 8-, 16-, 32-, and
|
|
* 64-bit types if they are implemented. Other exact width types are optional.
|
|
* This implementation defines an exact-width types for every integer width
|
|
* that is represented in the standard integer types.
|
|
*
|
|
* The standard also requires minimum-width types be defined for 8-, 16-, 32-,
|
|
* and 64-bit widths regardless of whether there are corresponding exact-width
|
|
* types.
|
|
*
|
|
* To accommodate targets that are missing types that are exactly 8, 16, 32, or
|
|
* 64 bits wide, this implementation takes an approach of cascading
|
|
* redefinitions, redefining __int_leastN_t to successively smaller exact-width
|
|
* types. It is therefore important that the types are defined in order of
|
|
* descending widths.
|
|
*
|
|
* We currently assume that the minimum-width types and the fastest
|
|
* minimum-width types are the same. This is allowed by the standard, but is
|
|
* suboptimal.
|
|
*
|
|
* In violation of the standard, some targets do not implement a type that is
|
|
* wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
|
|
* To accommodate these targets, a required minimum-width type is only
|
|
* defined if there exists an exact-width type of equal or greater width.

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