Jakob Stoklund Olesen 2710638db2 Evict a lighter single interference before attempting to split a live range. ... Registers are not allocated strictly in spill weight order when live range splitting and spilling has created new shorter intervals with higher spill weights. When one of the new heavy intervals conflicts with a single lighter interval, simply evict the old interval instead of trying to split the heavy one. The lighter interval is a better candidate for splitting, it has a smaller use density. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125151 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-09 01:14:03 +00:00
