Chris Lattner f7da2c7b0c Take advantage of the recent improvements to the liveintervals set (tracking ... instructions which define each value#) to simplify and improve the coallescer. In particular, this patch: 1. Implements iterative coallescing. 2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a better solution. 3. Implements PR865, "coallescing" away the second copy in code like: A = B ... B = A This also includes changes to symbolically print registers in intervals when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29862 91177308-0d34-0410-b5e6-96231b3b80d8		2006-08-24 22:43:55 +00:00
