It is technically allowed to move a normal load across a volatile load, but probably not a good idea. It is not allowed to move a load across an atomic load with Ordering > Monotonic, and we model those with MOVolatile as well. I recently removed the mayStore flag from atomic load instructions, so they don't need a pseudo-opcode. This patch makes up for the difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162857 91177308-0d34-0410-b5e6-96231b3b80d8
