I read the bounty offer and they didn't touch assembly at all, so it remains the same. See point #4 in https://www.memorysafety.org/blog/rav1d-perf-bounty/

The dav1d and rav1d decoders share the exact same low-level assembly code optimizations—you cannot modify this assembly. You must improve the Rust code (or the Rust compiler), which is what differs between dav1d and rav1d. You may not introduce code into rav1d in a language other than Rust. We encourage you to ask questions early on in issues or by emailing us so as to avoid investing heavily in something that might not be eligible!
