Just out curiosity, have you implemented a new register allocation algorithm
and if so, which one? I'm working on code generator right now and I'm
looking for a simple register allocation algorithm to implement and how to
deal with fixed registers to cetain instructions like eax/ebx to mul/div on
x86. I've asked this before
(http://llvm.1065342.n5.nabble.com/How-do-I-deal-with-fixed-registers-td68697.html)
but no one asnwered yet.
