Alkis Evlogimenos 26bfc08b80 Add coalescing to register allocator. A hint is added to each interval ... which denotes the register we would like to be assigned to (virtual or physical). In register allocation, if this hint exists and we can map it to a physical register (it is either a physical register or it is a virtual register that already got assigned to a physical one) we use that register if it is available instead of a random one in the free pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10634 91177308-0d34-0410-b5e6-96231b3b80d8		2003-12-28 17:58:18 +00:00
