Really cool article. This sort of stuff is mind expanding for me! I wonder what it would take to make a version that works on Windows. Will you indulge me?

  wazero works fine on Windows. In fact the exact same assembly works across Windows, macOS, Linux and FreeBSD: the calling convention used by the compiler is entirely custom, and all "host calls" are provided by wazero, so assembly ports fine across OSes.

    Perhaps I was unclear (or I'm confused now, haha): > The following is the tiny demo of the runtime code generation and execution in Go. I assume you are on a Unix-like system like Linux or macOS on an AArch64 machine. Is there a way to get tinydemo working on Windows?

      Oh, OK. You need to replace calls to syscall.Mmap with windows.VirtualAlloc [1], syscall.Mprotect with windows.VirtualProtect, etc. You don't even need to change the ASM preamble.

        and for reference see how it's done in wazero https://github.com/tetratelabs/wazero/blob/c397a402ad17e495a5a22fef709a1d4abef1f3ce/internal/platform/mmap_windows.go https://github.com/tetratelabs/wazero/blob/c397a402ad17e495a...
