Juergen Ributzka 58bc0ca37b [DAG] Don't pull the binary operation though the shift if the operands have opaque constants. ... During DAGCombine visitShiftByConstant assumes that certain binary operations with only constant operands can always be folded successfully. This is no longer true when the constant is opaque. This commit fixes visitShiftByConstant by not performing the optimization for opaque constants. Otherwise we would end up in an infinite DAGCombine loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200900 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-06 04:09:06 +00:00
