[RFC] Framework for Finding and Using Similarity at the IR Level
...and try to use target hooks, but not all of the target hooks that we would really want exist. So, if it has been applied, I’ll definitely need to take a look.
I applied the patches in order on top of your commit of D86974
(15645d044bc) that is:
D86975 - D86976 - D86977 - D86978 - D87294 - D87296 - D87298 - D87299 - D87300
D87301 - D87302 - D87309 - D87310
So, the cost model was part of it, I don't remember if I had to
resolve some conflicts for
it, but I'll re-check and look if it was applied correctly.

[RFC] Framework for Finding and Using Similarity at the IR Level
Indeed, an awesome project and an excellent report!
Code size doesn't really get much attention, so the level of detail and the
strong roadmap is refreshing.
Hopefully, the project will provide execution times along with code-size

I doubt it.
Outlining will (almost?) always make for slower code due to a lot more
calls being made. But that's ok for embedded targets,

Hi Andrew,
Thanks for this great work and presentation, I've also a huge interest in code
size reduction. I already looked at the first IR Outliner proposal,
and I really
like your more general approach.
I wanted to look at the impact on ARM targets, and managed to apply
your patchset
up to D87311 (the remaining ones which are related to call instructions and GEP
need to be reworked to be
