RISC-V is. I am self-hosting many of my internet thingies. I plan to move to RISC-V only hardware and to rewrite my internet software directly in mono-threaded paranoid RISC-V assembly.
Good luck with your RISC-V asm stuff! Hit me up if you publish any of it :)
I am currently attempting to define some binary specifications for a wayland compositor on linux, and to do that I write RISC-V assembly which I run on x86_64 thx to a very small interpreter. So the "cleanup" will happen "after" I get my own real-life wayland compositor (I am currently finishing the memory layout for keyboard and mouse support if you were curious about it).
Letting people know here is seriously compromised: HN started to aggressively block web browsers which are not based on one of the 'whatwg cartel' web engines, or their security provider is in love with gogol, dunno, could be my internet lines actively filtered too :) noscript/basic HTML is the only way for web freedom.
Why is that a problem? Google search returns 3K page arm64 ISA manual. What else do you need to write asm?
I think with RISC-V if you wanted to design your own chips and stuff you can just do it, whereas ARM doesn't let you do that.
I'm not about to build my own chips so it doesn't matter all that much to me but I understand where the person is coming from. They'd rather write assembly for the more open architecture.
