-On 64-bit-machines (like the Alpha) all operands are stored in the
-registers in a 64-bit form, even when the correspondig JavaVM  operands
-only need 32 bits. This is done by a canonical representation:
-
-32-bit integers are allways stored as sign-extended 64-bit values (this
-approach is directly supported by the Alpha architecture and is very easy
-to implement).
