Andrew Trick 8adae96fd9 Evict local live ranges if they can be reassigned. ... The previous change to local live range allocation also suppressed eviction of local ranges. In rare cases, this could result in more expensive register choices. This commit actually revives a feature that I added long ago: check if live ranges can be reassigned before eviction. But now it only happens in rare cases of evicting a local live range because another local live range wants a cheaper register. The benefit is improved code size for some benchmarks on x86 and armv7. I measured no significant compile time increase and performance changes are noise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187140 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-25 18:35:19 +00:00
