LICM correctly. When sinking an instruction, it should not add entries for the sunk instruction to the AST, it should remove the entry for the sunk instruction. The blocks being sunk to are not in the loop, so their instructions shouldn't be in the AST (yet)! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112447 91177308-0d34-0410-b5e6-96231b3b80d8
