+ builds. It allocates registers on a basic block level, attempting to keep
+ values in registers and reusing registers as appropriate.</li>

+ <li><i>PBQP</i> — A Partitioned Boolean Quadratic Programming (PBQP)
+ based register allocator. This allocator works by constructing a PBQP
+ problem representing the register allocation problem under consideration,
+ solving this using a PBQP solver, and mapping the solution back to a
+ register assignment.</li>
