| * | Fix 12892. | Jakob Stoklund Olesen | 2012-05-19 |
| Dead code elimination during coalescing could cause a virtual register to be split into connected components. The following rewriting would be confused about the already joined copies present in the code, but without a corresponding value number in the live range. Erase all joined copies instantly when joining intervals such that the MI and LiveInterval representations are always in sync. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157135 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
