Nomenclature: all ops indicate width and signedness, where
appropriate. Widths: 8/16/32/64 means the given size, obviously.
- Nat means the native word size. Signedness: S means signed, U
- means unsigned. For operations where signedness is irrelevant or
- makes no difference (for example integer add), the signedness
- component is omitted.
+ Nat means the operation works on STG word sized objects.
+ Signedness: S means signed, U means unsigned. For operations where
+ signedness is irrelevant or makes no difference (for example
+ integer add), the signedness component is omitted.
An exception: NatP is a ptr-typed native word. From the point of
view of the native code generators this distinction is irrelevant,
