================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineSelect.cpp:2555
   // FIXME: Remove this workaround when freeze related patches are done.
   // For select with undef operand which feeds into an equality comparison,
   // don't simplify it so loop unswitch can know the equality comparison
----------------
@spatel can you look at this fixme?
