Unfortunatly, that doesn't mean that it works:

- it doesn't handle architectures with multiple stacks (ia64)
- it relies on $fp being constant through out the lifetime of the frame 
(including the prologue) and that is definitly not true
- I suspect it is also making similar assumptions about $pc, it should 
be using func.
