2010-11-11Check TRI->getReservedRegs because other allocators do it. Even thoughAndrew 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

2010-11-11Insert two blank SlotIndexes between basic blocks instead of just one.Jakob Stoklund Olesen
This is the first small step towards using closed intervals for liveness instead of the half-open intervals we're using now. We want to be able to distinguish between a SlotIndex that represents a variable being live-out of a basic block, and an index representing a variable live-in to its successor. That requires two separate indexes between blocks. One for live-outs and one for live-ins. With this change, getMBBEndIdx(MBB).getPrevSlot() becomes stable so it stays greater than any instructions inserted at the end of MBB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118747 91177308-0d34-0410-b5e6-96231b3b80d8
