Cool! I haven't thoroughly read the history of that diff, but allowing

A long time ago, I’ve tried to inject plugin logic to allows some control over
the driver pipeline (phase ordering) and hooking various code gen related
functions.

At that time I ran into issues that might simply not exist with plugins anymore

I think it sounds like a potentially good idea in general, but I agree with
Ben and Matthew here that a more concrete plan of intended use is needed.
Adding "pluggable backends" to spin up new targets seems to require quite a
bit of additional infrastructure for initialising a library directory an

Sounds like a reasonable idea to me. However, you should take some
time to propose a concrete interface as this part was not obvious in
the design of source plugins.

Hi all,
I'm thinking of adding "backend plugins" in the current Plugins
mechanism which allows one to inspect/modify the IRs post simplifier
pass (STG/Cmm), similar to the recently added source plugins for HsSyn
IRs. This can be useful for anyone creating a custom GHC backend to
target an experime
