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>
</blockquote>
Reread your mail/output once more and honestly, I do not
understand what happens there.<br>
Can you share exact setup where you get this?<br>
