||
| 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. |
