not quite, i'm still using most of the python code (everything but the
register allocator, which is just one file). explanation here:

can you point me to the bugtracker

no, since i didn't mention it on a bug tracker iirc, but the bug tracking
it is (needs a bunch of sub-task bugs for reg-alloc, toom-cook, integration
with isacaller, etc.)

actually iirc it has since it's a subtask of the fast rsa modular
exponentiation task.

the reg alloc experimentation is also quite useful for figuring out how
SVP64 will be integrated into llvm, gcc, cranelift, etc.
