> This looks great! Please consider upstreaming this into LLVM; it would benefit many other users of LLVM. I'd love to see this used in Rust, for instance.

Or in straight C++ for that matter.

Though possibly the optimisation passes relies on specific properties of the target which don't exist for non-wasm? I didn't see anything in the writeup but that doesn't mean they don't exist.

PartialExecuter happens at the LLVM's IR level, and in theory it's fully generic. Then has been only partially tested outside the Cheerp-pipeline, so I would expect it to rely on some implicit assumptions on the kind of legalizations or lowering that are done before-hand.

Target-wise, all information is kept encoded in the IR, so that part is easier (the only strange thing that might happens is bumping some alignment to 8, but I expect every target to be able to handle the prescribed IR alignemtn)
