llvm/test/Transforms/MemCpyOpt
History
Ahmed Bougacha 8eca988b00 [MemCpyOpt] Do move the memset, but look at its dest's dependencies. 
In effect a partial revert of r237858, which was a dumb shortcut.
Looking at the dependencies of the destination should be the proper
fix: if the new memset would depend on anything other than itself,
the transformation isn't correct.
