A high performance WebAssembly interpreter in C

Wasm3

This is an (experimental) high performance WebAssembly interpreter written in C.

∼ 10x faster than other wasm interpreters (wasm-micro-runtime, wac, life)
∼ 5-6x slower than state of the art wasm JIT engines, like liftoff
∼ 10-15х slower than native execution
_{* Your mileage may vary}

Status

Minimum useful system requirements: ~64Kb for code and ~10Kb RAM

wasm3 currently runs on a wide range of platforms:

• Linux, Windows, OS X
• Android
• Raspberry Pi, Orange Pi and other SBCs
• MCUs:
  Arduino MKR*, Arduino Due, Particle Photon,
  ESP8266, ESP32, Air602 (W600), nRF52, nRF51,
  Blue Pill (STM32F103C8T6), MXChip AZ3166 (EMW3166),
  Maix (K210), HiFive1 (E310), Fomu (ICE40UP5K), etc.
• OpenWRT-enabled routers
• Browsers... yes, using WebAssembly itself!
• TODO: run on wasm3 (should be self-hosting)

wasm3 is built on top of Steven Massey's novel interpreter topology, with:

• Aim at Wasm 1.0 spec conformance (not there yet)
• Lot's of bugfixes
• Portability improvements
