Ruby has support for plenty of "exotic" systems like HP UX, AIX etc. It's unclear how many people actually use it, but it's there. > I don't know if they want to use an existing JIT codegen like LLVM or Cranelift, or their own. Their own.

Fun bit of trivia.. Ruby only (officially) dropped Atari ST support in 2016: https://github.com/ruby/ruby/blob/c5eb24349a4535948514fe765c3ddb0628d81004/doc/ChangeLog-2.4.0#L4155 https://github.com/ruby/ruby/blob/c5eb24349a4535948514fe765c... .. I've never heard of anyone actually using Ruby on an Atari ST though(!)

At least in what concerns AIX, IBM has migrated their compilers on top of LLVM, so some support is there. No idea about HP-UX, it is impossible to find anything now, apparently HPE has buried almost everything about it. Completely unrelated to how good it used to be about 20 years ago.

  I just gave a couple examples I had in mind because they came up recently. The point was that the parent's assertion: > you wouldn't use ruby outside of Linux, Windows, Mac, FreeBSD, OpenBSD Isn't quite true.

    Agreed.

I wasn't even referring to CRuby, I was referring to YJIT especially. For now, it only works on x86_64 Unix like systems (Linux and mac). I doubt that someone will ever port YJIT codegen to these "esoteric" architectures, so rust platform support is enough.

  > I wasn't even referring to CRuby, I was referring to YJIT especially. My bad, that's really not what I understood from your initial statement. But yes agreed. The only real downside is discussed on the ticket. Ruby is primarily installed from source, so requiring a second toolchain is not ideal.

  While those that were willing to make it happen, now have to wait until Rust/Zig supports their esoteric architecture.
