Haoran Xu (Apr 13 2021 at 07:02): Haoran Xu (Apr 13 2021 at 07:02):Hello,
I'm wondering if there is any way I could test the lightbeam compiler. I tried to build wasmtime from source with lightbeam enabled with the following command:
cargo build --release --features lightbeam
I then tried to invoke the lightbeam compiler:
./wasmtime --lightbeam ~/coremark-wasi.wasm
However, I get a panic at crates/lightbeam/wasmtime/src/lib.rs:224. It seems like this function is newly added, so I tried to checkout and build a few older versions of wasmtime. But it still doesn't work: I just get panics at different places.
Can anyone offer me help on testing the performance of the Lightbeam compiler? Thanks!

Its main author (Vurich) has not contributed for about a year by now so I also would not expect a lot of momentum for it. Technically the backend can be compared with the Wasmer singlepass backend.
