On: Fastly hires entire Wasmtime team from Mozilla

Had an idea of trying to "script" things for games, the idea was to use a the WASM backend of a regular C/C++ compiler to generate code that could be loaded dynamically and share structures (ignoring sandbox for this) so that testing could be done seamlessly, sadly WASM seems to be 32bit for the time being (atleast for Clang, dunno about GCC but that has other issues), also looked at Risc-V and missing export/import tables looks like it could make things far more complicated (might still try using Risc-V though since i'm thinking of generating syscall tables automatically along with Elf-loading)

Sounds awesome. I have some abstractions for making interfacing easier, but I don't have any auto-generated structures.

I have done that here. Example:

    APICALL(api_math_smoothstep)
    {
        auto [edge0, edge1, x] = machine.sysargs <float, float, float> ();
        x = std::clamp((x - edge0) / (edge1 - edge0), 0.0f, 1.0f);
        machine.cpu.registers().getfl(10).set_float(x * x * (3 - 2 * x));
        return 0;
    }

"machine" is an argument to each system call handler, so you can have multiple machines for many purposes. For example, I suspect you can use a machine as a savegame - because they are serializable.

Oh! So the emulator i was looking at was yours, it looked damn nice for just this task and i guess i know why now :D

Good choice on using var-arg-templates for passing arguments between env and host, i think moving over all scripting bindings to va-templatized bindings is the only sane option for the future (boy have i spent time fighting binding bugs in my days)
