Evan Cheng 752195e3c6 Add early coalescing to liveintervals. This is work in progress and is known to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this. ... The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81796 91177308-0d34-0410-b5e6-96231b3b80d8		2009-09-14 21:33:42 +00:00
