<div dir="ltr"><div dir="ltr">Hi Leonard, Fedor,<div><br></div><div>while it's true that RegisterPass is not applicable for new-pm passes, PassRegistry.def is not the whole story. Passes in PassRegistry are available for the opt tool. The sanitizers are passes that usually get added to the pipeline by the frontend.

nope, the PassRegistry stuff is all about legacy pass manager.<br>
legacy namespace has not been extensively used to mark all the <br>
legacy-related stuff<br>
(say, even Pass class which is a base for legacy passes is not under <br>
legacy namespace).<br>
<br>
Registration for new-pass-manager passes happens in <br>
lib/Passes/PassRegistry.def.<br>
<br>
Usually, when porting from legacy to new the main difference is analysis <br>
handling,<br>
so people factor out the worker code into a method that takes analyses <br>
and call<br>
this function both in legacy and new-pm passes.<br>
In many cases it takes just a handful lines of code.<br>
<br>
Feel free to ask questions, if any.<br>
<br>
regards,<br>
Fedor.<br>
