[LLVMdev] PBQP spilling
Hi Quentin, Jonas,
Splitting fits in with PBQP reasonably well, at least conceptually. The
PBQP graph is designed to be mutable, so there is no problem with updating
it when splitting.
As I see it, there are two logical places to integrate splitting into PBQP:
1) Split during spilling -- If a PBQP solution selects the spill option for
a node, rather than spill immediately, split the interval
