Recently I was reminded of x32 Linux ABI . I read about it few years ago when it was being merged to Linux kernel, but not much afterwards. I understand that it did not become popular. It is not better enough to justify the hassle of yet another architecture. Of course there is also the chicken and the egg problem of library support.
I’m wondering if it would be a bit better for older machines. But problems stated earlier still stand. Maybe it would be useful for ChromeOS-like OS.
Nevertheless does anyone use it? Professionally or personally?
