Robin Morisset 0acd42142a Answer to Philip Reames comments ... - add check for volatile (probably unneeded, but I agree that we should be conservative about it). - strengthen condition from isUnordered() to isSimple(), as I don't understand well enough Unordered semantics (and it also matches the comment better this way) to be confident in the previous behaviour (thanks for catching that one, I had missed the case Monotonic/Unordered). - separate a condition in two. - lengthen comment about aliasing and loads - add tests in GVN/atomic.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215943 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-18 22:18:14 +00:00
