Cameron Zwarich 4071a71112 Do some peephole optimizations to remove pointless VMOVs from Neon to integer ... registers that arise from argument shuffling with the soft float ABI. These instructions are particularly slow on Cortex A8. This fixes one half of <rdar://problem/8674845>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128759 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-02 02:40:43 +00:00
