80 | * natural_t and integer_t are Mach's legacy types for machine- |
81 | * independent integer types (unsigned, and signed, respectively). |
82 | * Their original purpose was to define other types in a machine/ |
83 | * compiler independent way. |
84 | * |
85 | * They also had an implicit "same size as pointer" characteristic |
86 | * to them (i.e. Mach's traditional types are very ILP32 or ILP64 |
87 | * centric). We will likely support x86 ABIs that do not follow |
88 | * either ofthese models (specifically LP64). Therefore, we had to |
89 | * make a choice between making these types scale with pointers or stay |
90 | * tied to integers. Because their use is predominantly tied to |
91 | * to the size of an integer, we are keeping that association and |
92 | * breaking free from pointer size guarantees. |
93 | * |
94 | * New use of these types is discouraged. |
