MiniVM: A zero-dependency cross-language runtime on par with LuaJIT and C

That sounds like a solid basis for adding asymmetric coroutines as well, is that something you're thinking about adding?

I like the philosophy and gumption shown by this project but coroutines aren't a feature I'd lightly give up.

Digging what I see so far!

MiniVM uses coroutines already, every 1000 branches the vm will return to the scheduler. The Build system can accept CFLAGS+=-DVM_BRANCH_DEFER which makes MiniVM able to run part of bytecode up-to N instructions.

It is not exposed on the insruction level yet tho. Would be quite easy to add.

Ah thank you, that's very promising! It was the kind of thing I wanted to hear, I write Lua every day and four data types didn't appear to support 'thread'.

I might just kick the tires on this over the weekend.

That’s cool. Have you played around with that number? I’m curious how you pick that constant and what the trade offs are

It might be interesting to be able to tell the VM to resume into code for exactly N instructions or branches. I can see instrumentation/debugging tooling using this with N=1 for example.
