Andrew Trick 14e8d71cc9 This is a prototype of an experimental register allocation ... framework. It's purpose is not to improve register allocation per se, but to make it easier to develop powerful live range splitting. I call it the basic allocator because it is as simple as a global allocator can be but provides the building blocks for sophisticated register allocation with live range splitting. A minimal implementation is provided that trivially spills whenever it runs out of registers. I'm checking in now to get high-level design and style feedback. I've only done minimal testing. The next step is implementing a "greedy" allocation algorithm that does some register reassignment and makes better splitting decisions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117174 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-22 23:09:15 +00:00
