All Intel CPUs since Yonah look a lot alike, at least at the granularity of the scheduling models. We can add more accurate models for processors that aren't Sandy Bridge if required. Haswell will probably need its own. The Atom processor and anything based on NetBurst is completely different. So are the non-Intel chips. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178080 91177308-0d34-0410-b5e6-96231b3b80d8
