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 applied or work correctly). I looked at CTMark code size other -Oz for both ARM and X86 and got a huge code size increase on both targets (around 30% or 40% in Geomean) when compiled with -mllvm -ir-outline...

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 > reductions. > 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,
