Jakob Stoklund Olesen 87f7864c6d Merge into undefined lanes under -new-coalescer. ... Add LIS::pruneValue() and extendToIndices(). These two functions are used by the register coalescer when merging two live ranges requires more than a trivial value mapping as supported by LiveInterval::join(). The pruneValue() function can remove the part of a value number that is going to conflict in join(). Afterwards, extendToIndices can restore the live range, using any new dominating value numbers and updating the SSA form. Use this complex value mapping to support merging a register into a vector lane that has a conflicting value, but the clobbered lane is undef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164074 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-17 23:03:25 +00:00
