* Store (priority,regnum) pairs in the priority queue instead of providing anJakob Stoklund Olesen2010-12-08
| | | | | | | | | | | | | | | | | | | | | | | abstract priority queue interface in subclasses that want to override the priority calculations. Subclasses must provide a getPriority() implementation instead. This approach requires less code as long as priorities are expressable as simple floats, and it avoids the dangers of defining potentially expensive priority comparison functions. It also should speed up priority_queue operations since they no longer have to chase pointers when comparing registers. This is not measurable, though. Preferably, we shouldn't use floats to guide code generation. The use of floats here is derived from the use of floats for spill weights. Spill weights have a dynamic range that doesn't lend itself easily to a fixpoint implementation. When someone invents a stable spill weight representation, it can be reused for allocation priorities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121294 91177308-0d34-0410-b5e6-96231b3b80d8
