Evan Cheng 70071434ae Initial support for copy elimination by commuting its definition MI. ... PR1877. A3 = op A2 B0<kill> ... B1 = A3 <- this copy ... = op A3 <- more uses ==> B2 = op B0 A2<kill> ... B1 = B2 <- now an identify copy ... = op B2 <- more uses This speeds up FreeBench/neural by 29%, Olden/bh by 12%, oopack_v1p8 by 53%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47046 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-13 03:01:43 +00:00
