There is the https://en.wikipedia.org/wiki/X32_ABI https://en.wikipedia.org/wiki/X32_ABI for AMD64 at least. But it's looking rather bitrotten and is frowned upon by the snobs. Nobody is using it. Justine Tunney's https://www.justinetunney.com/ https://www.justinetunney.com/ APE and Cosmopolitan libc shows what's possible, though. https://www.justinetunney.com/cosmo3/ https://www.justinetunney.com/cosmo3/ https://www.justinetunney.com/ape.html https://www.justinetunney.com/ape.html https://www.justinetunney.com/matmul/ https://www.justinetunney.com/matmul/ And then there is vibecoded stuff like https://isene.org/chasm/ https://isene.org/chasm/ I think there is much more to be expected coming from that direction, overthrowing decades old cargo-cults :-)
