================
Comment at: llvm/lib/Target/PowerPC/PPCISelLowering.cpp:1329
     setOperationAction(ISD::INTRINSIC_VOID, MVT::i128, Custom);
   }
 
----------------
You probably want an "else" here to call `setMaxAtomicSizeInBitsSupported(64)` or something like that.  But you can leave that to a followup patch if you want.
