Recently bzip2 has used c2rust to transpile c to rust code, and gate it behind a feature flag.

I think doing the same on ring would be beneficial, it would:

remove c compiler as a dependency, that would also enable easier cross compilation and LTO
build script can be removed if transpiled rust code is used instead of the c code
make it possible to run miri over ring

It would be a difficult though, especially because all the assembly has to be rewritten into rust as well.

Putting them into C as inline assembly might make it easier though.
