CFLAA didn't know how to properly handle ConstantExprs; it would silently ignore them. This was a problem if the ConstantExpr is, say, a GEP of a global, because CFLAA wouldn't realize that there's a global there. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231743 91177308-0d34-0410-b5e6-96231b3b80d8
