-Datatypes and Register Allocations:
------------------------------------
-
-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).
-
-32-bit-floats are stored in a 64-bit doubleprecision register by simply
-expanding the exponent and mantissa with zeroes. (also supported by the
-architecture)
-
-
-Stackframes:
-
-The calling conventions and the layout of the stack is explained in detail
-in the documention file: calling.doc
