Tim Northover 44697f3fc1 X86 CodeGenPrep: sink shufflevectors before shifts On x86, shifting a vector by a scalar is significantly cheaper than shifting a vector by another fully general vector. Unfortunately, because SelectionDAG operates on just one basic block at a time, the shufflevector instruction that reveals whether the right-hand side of a shift is really a scalar is often not visible to CodeGen when it's needed. This adds another handler to CodeGenPrepare, to sink any useful shufflevector instructions down to the basic block where they're used, predicated on a target hook (since on other architectures, doing so will often just introduce extra real work). rdar://problem/16063505 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201655 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-19 10:02:43 +00:00
