As far as I understand it, SSA is part of LLVM so using
LLVM provides you with SSA optimised code for free,
which is good.

On the other hand, I prefer a translation that I can
easily relate to the original code. Of course flags
removal is a must to make the translated code
readable. Then the host compiler can do whatever
kind of optimisations it can. I have a project in
mind to use QEMU for that (of course that'd be for
recent processors).

Yeah might be fun :-) I have lost all links to Orion
download (I changed my machine a few months ago and was
too lazy to backup files...).
