2010-10-22This is a prototype of an experimental register allocationAndrew Trick
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

2010-10-22Be more strict about detecting multi-use blocks for isolation.Jakob Stoklund Olesen
When a block has exactly two uses and the register is both live-in and live-out, don't isolate the block. We would be inserting two copies, so we haven't really made any progress. If the live-in and live-out values separate into disconnected components after splitting, we would be making progress. We can't detect that for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117169 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-22Be more strict when detecting critical edges before loop splitting.Jakob Stoklund Olesen
