It will soon need the context.

be97e906e03dd9b22e14f6749157c9d5f9701dd5 09-Jan-2011 Jakob Stoklund Olesen <stoklund@2pi.dk> Teach TargetRegisterInfo how to cram stack slot indexes in with the virtual and
physical register numbers.

This makes the hack used in LiveInterval official, and lets LiveInterval be
oblivious of stack slots.

The isPhysicalRegister() and isVirtualRegister() predicates don't know about
this, so when a variable may contain a stack slot, isStackSlot() should always
be tested first.

only a single type of object to be allocated. Use it to make VNInfo destruction
typesafe.

233a60ec40b41027ff429e2f2c27fa2be762f2e9 04-Nov-2009 Lang Hames <lhames@gmail.com> The Indexes Patch.

This introduces a new pass, SlotIndexes, which is responsible for numbering
instructions for register allocation (and other clients). SlotIndexes numbering
is designed to match the existing scheme, so this patch should not cause any
changes in the generated code.

For consistency, and to avoid naming confusion, LiveIndex has been renamed
SlotIndex.

The processImplicitDefs method of the LiveIntervals analysis has been moved
into its own pass so that it can be run prior to SlotIndexes. This was
necessary to match the existing numbering scheme.

c781a243a3d17e7e763515794168d8fa6043f565 03-May-2009 Evan Cheng <evan.cheng@apple.com> In some rare cases, the register allocator can spill registers but end up not utilizing registers at all. The fundamental problem is linearscan's backtracking can end up freeing more than one allocated registers. However, reloads and restores might be folded into uses / defs and freed registers might not be used at all.

VirtRegMap keeps track of allocations so it knows what's not used. As a horrible hack, the stack coloring can color spill slots with *free* registers. That is, it replace reload and spills with copies from and to the free register. It unfold instructions that load and store the spill slot and replace them with register using variants.

Not yet enabled. This is part 1. More coming.
