| 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. |

| 482 | * |
| 483 | * The presence of limit macros are completely optional in C99. This |
| 484 | * implementation defines limits for all of the types (exact- and |
| 485 | * minimum-width) that it defines above, using the limits of the minimum-width |
| 486 | * type for any types that do not have exact-width representations. |
| 487 | * |
| 488 | * As in the type definitions, this section takes an approach of |
| 489 | * successive-shrinking to determine which limits to use for the standard (8, |
| 490 | * 16, 32, 64) bit widths when they don't have exact representations. It is |
| 491 | * therefore important that the definitions be kept in order of decending |
| 492 | * widths. |
| 493 | * |
| 494 | * Note that C++ should not check __STDC_LIMIT_MACROS here, contrary to the |
| 495 | * claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]). |
