| * Their original purpose was to define other types in a machine/ |
| * compiler independent way. |
| * |
| * They also had an implicit "same size as pointer" characteristic |
| * to them (i.e. Mach's traditional types are very ILP32 or ILP64 |
| * centric). We support x86 ABIs that do not follow either of |
| * these models (specifically LP64). Therefore, we had to make a |
| * choice between making these types scale with pointers or stay |
| * tied to integers. Because their use is predominantly tied to |
| * to the size of an integer, we are keeping that association and |
| * breaking free from pointer size guarantees. |
| * |
| * New use of these types is discouraged. |
