> Sounds good. I was trying to figure out how to invoke the new pass manager with OPT. Is there a command line switch to do that?

If you just do `opt -passes=<pass_names>`, it will invoke new pass manager for `opt`. See https://reviews.llvm.org/D66560 for example - that was for legacy PM, the equivalent for new PM would be something like `opt < %s 2>&1 -passes=forceattrs ...`
