Arnold Schwaighofer 6b6050b229 X86 cost model: Vector shifts are expensive in most cases ... The default logic does not correctly identify costs of casts because they are marked as custom on x86. For some cases, where the shift amount is a scalar we would be able to generate better code. Unfortunately, when this is the case the value (the splat) will get hoisted out of the loop, thereby making it invisible to ISel. radar://13130673 radar://13537826 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178703 91177308-0d34-0410-b5e6-96231b3b80d8		2013-04-03 21:46:05 +00:00
