I am coding my own wayland compositor, in rv64 assembly... running on x86_64 with a small interpreter.

I am currently only using the core ISA (no compressed instructions, not even the pseudo instructions), and I use a C preprocessor to avoid to get my code locked on the preprocessor of one assembler.

I started to code assembly when I was a teenager as it is not hard: only uncomfortable. Nowdays, with what seems a real global, no IP locks, ISA, RISC-V, it is very reasonable to write directly assembly, as (real and sane) standard assembly is extremely efficient at fighting planned obsolecence.
