See upstream: gz/rust-cpuid#45 (comment)
Running into this issue via wasmtime PyPI package used by yowasp-yosys.

Thanks for the report! It looks like this is coming from the raw-cpuid crate which was removed in #2607. Looking at yosys I think an older version of Wasmtime is being pulled in, so I think that this isn't a bug in Wasmtime itself but perhaps a place where the python wasmtime dep needs to be updated?

Ok, thanks!
