2013-01-20LoopVectorizer: Implement a new heuristics for selecting the unroll factor.Nadav Rotem
We ignore the cpu frontend and focus on pipeline utilization. We do this because we don't have a good way to estimate the loop body size at the IR level. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172964 91177308-0d34-0410-b5e6-96231b3b80d8
