For example, the first instruction in the code below can be eliminated if the use of $vr0 is replaced with $zero: addiu $vr0, $zero, 0 add $vr2, $vr1, $vr0 add $vr2, $vr1, $zero git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152280 91177308-0d34-0410-b5e6-96231b3b80d8		2012-03-08 01:51:59 +00:00
