* Fixed a bug in the PBQP allocator's findCoalesces method.Lang Hames2010-02-091-6/+17
| | | | | | | | Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95636 91177308-0d34-0410-b5e6-96231b3b80d8
