RISC-V OS using Rust: Filesystems

Re:RISC-V OS using Rust: Filesystems by jcranmer on Tuesday May 12, 2020 @01:35PM (#23156896)

There is a proposal for a new asm! macro: https://github.com/Amanieu/rfcs/blob/inline-asm/text/0000-in... (note that the last updated date was 2 days ago, as of the time of this comment).

It looks like what you're referring to is the interim plan to rename asm! to llvm_asm! (which will never be stabilized), since it's a very thin wrapper over the current LLVM inline asm support, and then replace asm! with a better implementation.

There is a working group specifically for inline asm, so it will happen eventually... but it's not going to be a quick process--think about how long async/await takes, and inline asm is actually rather close to that in terms of all the issues that come out of it.

Wow, that looks like a lot of work went into this RFC. I'm glad it's being taken seriously, and I anxiously await the outcome--whatever that might be.

Thank you!
