Evan Cheng a2e6435e48 Two coalescer fixes in one. ... 1. Use the same value# to represent unknown values being merged into sub-registers. 2. When coalescer commute an instruction and the destination is a physical register, update its sub-registers by merging in the extended ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66610 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-11 00:03:21 +00:00
