2010-11-20	Whitespace.	Andrew Trick
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119895 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-11	Check TRI->getReservedRegs because other allocators do it. Even though	Andrew Trick
	it makes no sense for allocation_order iterators to visit reserved regs. The inline spiller depends on AliasAnalysis. Manage the Query state to avoid uninitialized or stale results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118800 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-10	RABasic is nearly functionally complete. There are a few remaining	Andrew Trick
	benchmarks hitting an assertion. Adds LiveIntervalUnion::collectInterferingVRegs. Fixes "late spilling" by checking for any unspillable live vregs among all physReg aliases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118701 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09	Adds RABasic verification and tracing.	Andrew Trick
	(retry now that the windows build is green) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118630 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09	Reverting r118604. Windows build broke.	Andrew Trick
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118613 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09	Adds RABasic verification and tracing.	Andrew Trick
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118604 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-08	Adds support for spilling previously allocated live intervals to	Andrew Trick
	handle cases in which a register is unavailable for spill code. Adds LiveIntervalUnion::extract. While processing interferences on a live virtual register, reuses the same Query object for each physcial reg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118423 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03	Let RegAllocBasic require MachineDominators - they are already available and	Jakob Stoklund Olesen
	splitting needs them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118194 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-26	Jakob's review of the basic register allocator.	Andrew Trick
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117384 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-22	This is a prototype of an experimental register allocation	Andrew 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
