Here is a simple job for a C programmer with some math/algorithmical
brain:
fill the function body of Parrot_register_move() (src/utils.c 633 ff).
The desired functionality is hopefully documented enough.
If there is some code, we can use this e.g. for tailcalls and inside
JIT.
.sub foo
.param int I0
.param int I1
[EMAIL PROTECTED]: # label inserted with -Oc
...
.return foo(I1, I0) # problem with -Oc
.end
Recursive tailcall optimization will convert above code into a loop,
but it'll fail as registers will be clobbered during move:
set I0, I1
set I1, I0 # <--- problem

Thanks,
