How did you try to compile the function? Using cranelift_codegen::Context::compile or in sone other way?

Ohh.... I did it through some other avenue. Thank you for letting me know! I switched to using that same API you just mentioned, and everything works fine now. Thank you!

Great to hear you managed to get it working! The reason it didn't work through the other method you tried is likely because that other method skipped the "legalization" from stack_load to stack_addr combined with a regular load.
