Actually implementing these is pretty trivial (at least once all the scalar methods are added, which happens in #121926), but I'm staying consistent with the other f16/f128 PRs. Also adding adding all the tests to Miri would be quite a lot of work.

There's probably some way to reduce the code duplication here with more use of generics... but that's a future refactor.^^

Talk about excellent timing. Getting Miri tests to work with stage0 was a pain point for the proof of concept at https://github.com/rust-lang/rust/pull/114607/files#diff-24bd7b5e2ca32dd28044509d08e68ec5be1c382735128742baec9383acbd6fea. But with a beta branch in only 11 days, that won't be a concern as long as #121926 and some libs support land before then 🎉

That's only an issue for operations that need host floats. Most operations use soft floats which you can implement without any support in the bootstrap compiler. It'd be entirely fine to only land the softfloat operations in the first round.

The tests are a lot of work just because there's so many float operations.^^ And they have so many nasty corner-cases, too.
