Jon, Mario,

As Darin says, we plan to look at x86-64 in the very near future.

We see this as a good gateway to further architectures (as well as  
being an important architecture in its own right for SFX to support).   
It will force us to address a number of issues that many ports may  
face (pointers being larger than the size of immediate operands,  
setting memory protection on code buffers spring to mind) – whilst  
clearly having a lot in common with the existing x86 code generation.   
It should also see us start to introduce a layer of abstraction  
between the compiler and the architecture specific assembler.
