Apparently both yes and no.<br>
How do you run this?<br>
<br>
IR printing is implemented through pass instrumentation and is
enabled in e.g. opt through the use of StandardInstrumentation<br>
in llvm::runPassPipeline.<br>
If you set up NewPM by yourself w/o the use llvm::runPassPipeline
then most likely you just do not have StandardInstrumentation
installed.<br>
<br>

Fedor.
