A tiny, fast, portable, and embeddable low-level virtual machine.
rvm is now complete!
- Make sure you have
makeandgcc/clanginstalled. - Clone the repo.
- Run
make -C'path/to/repo'
For the APIs: Please read the source code. Check out test/test.c to see
how to set it up. I don't plan to write a full documentation, yet. Thanks for
understanding.
I've got no access to a PC. RVM was entirely built on my phone, which has these decent specs:
- processor: Unisoc T603
- cpu: 8 cores (4x 1.2GHz + 4x 1.8GHz)
- arch: armv8 (aarch64), little-endian
- ram: 4GB (+4GB swap)

CI benchmarks (GitHub-hosted runner):
| Test | Elapsed time | Inst Count | Avg TPI | Inst Rate |
|---|---|---|---|---|
nops |
456.413 μs | 1048576 (1.05 M) | 0.435ns | 2.297G IPS |

naive_fib_40 |

In the naive fib(40) test, RVM is ~2.5× slower than LuaJIT — but
orders of magnitude faster than Python!
