I see your position, but I've to say that in 8 years of rev.ng we revised many many design choices we initially made, but not using LLVM was not one of them, so I can't agree.

Rolling your own IR is not hard, in fact, it's very easy (and sometimes we roll temporary IRs for specific purposes), but it's also true that most IRs look more or less the same. QEMU's tiny code and LLVM IR, for instance, are quite similar. What matters is the ecosystem around them, and the ecosystem around LLVM is really great.

Anyway, every Friday morning 11:00 CEST we have the rev.ng hour, our weekly internal technical meeting. It would be interesting to discuss what limitations you hit with LLVM that we did not hit and your concerns about efficiency of LLVM and MLIR.

We used to stream the rev.ng hour and we're in the process of going back to publish some talks every now and then. If you're interested, drop me an e-mail! :)
