Thanks to Jakob for isolating the underlying problem from the test case in r177423. The original commit had introduced asymmetric copy operations, but these turned out to be a work-around to the real problem (the use of == instead of hasSubClassEq in PPCCTRLoops). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177679 91177308-0d34-0410-b5e6-96231b3b80d8
