Ah, raising CSR cost to be high enough and using existing splitting is indeed a simpler approach. I didn't think of the idea even after you hinted this in PR. I just tried https://reviews.llvm.org/D27366 and it can cover the simple testcases I have. I can help to evaluate the performance on x86 and see how the overall performance looks. Thanks!
