I’m writing my own scripting language in C#, with some features I like, and I chose to use MSIL as output’s bytecode (Reflection.Emit is quite useful, and I dont have to think up another bytecode). It works, emits executable, which can be run ( even decompiled with Reflector 🙂 )and is quite fast.

But – I want to run multiple ‘processes’ in one process+one thread, and control their assigned CPU time manually (also implement much more robust IPC that is offered by .NET framework) Is there any way to entirely disable JIT and create own VM, stepping instruction-after-instruction using .NET framework (and control memory usage, etc.), without need to write anything on my own, or to achieve this I must write entire MSIL interpret?

EDIT 1): I know that interpreting IL isn’t the fastest thing in the universe 🙂

EDIT 2): To clarify – I want my VM to be some kind of ‘operating system’ – it gets some CPU time and divides it between processes, controls memory allocation for them, and so on. It doesnt have to be fast, nor effective, but just a proof of concept for some of my experiments. I dont need to implement it on the level of processing every instruction – if this should be done by .NET, I wont mind, i just want to say : step one instruction, and wait till I told you to step next.

EDIT 3): I realized, that ICorDebug can maybe accomplish my needs, now looking at implementation of Mono’s runtime.

  1. You could use Mono – I believe that allows an option to interpret the IL instead of JITting it. The fact that it’s open source means (subject to licensing) that you should be able to modify it according to your needs, too.

    Mono doesn’t have all of .NET’s functionality, admittedly – but it may do all you need.
