Bytecode VMs in Surprising Places

• wasm-bpf

  7 332 7.1 Rust

  WebAssembly library, toolchain and runtime for eBPF programs

  

• valgrind

  2 15 0.0 C

  A mirror of the Valgrind library source code (version 3.13.0). This is NOT the official Valgrind source, please find official source at http://valgrind.org/ (by rantoniello)

The IR is here: https://github.com/rantoniello/valgrind/blob/master/VEX/pub/...

The rest can probably be found by searching around but I'm on my phone right now

• wasm-bpf-rs

  1 3 - Rust

• miri

  122 4,026 10.0 Rust

  An interpreter for Rust's mid-level intermediate representation

  

Miri [0] is an interpreter for the mid-level intermediate representation (MIR) generated by the Rust compiler. MIR is input for more processing steps of the compiler. However miri also runs MIR directly. This means miri is a VM. Of course it's not a bytecode VM, because MIR is not a bytecode AFAIK. I still think that miri is a interesting example.

And why does miri exist?

It is a lot slower. However it can check for some undefined behavior.
