You can open a large file using a File or Blob, which do not store all the data in memory at once. Then you can read slices from it. That even works synchronously, in Workers: https://developer.mozilla.org/en-US/docs&#x

A related example is image editing software like Adobe Photoshop on the Web. Large images can require more then 4GB in many cases.

Interesting, thanks! And good luck with your project.

There is also Wasmnizer-ts, which compiles TypeScript to WasmGC: https://github.com/web-devkits/Wasmnizer-ts How does Jaws compare to that?
125.
by azakai 2y ago
Sharing GC data between wasm modules is supported, yes. You just need to define the types identically on both sides, and things work.

I'm not sure there is a clear separation between applying heuristics and searching a space. Often in compilers you search a subset of a space using heuristics, and you can adjust those to control how much of the space you cover. For ex

For current support, see https://webassembly.org/features/ Chrome (and other Chromium-based browsers) and Firefox have had WasmGC enabled for a few releases now. But Safari doesn't yet last I heard. Sheets can ser

Yeah, exactly. The initial prototype turned out to be quite slow - a lot of optimizations are needed to be fast. The version as of now is 4x faster than that initial prototype, and 2x faster than the JS version. And we are working to make i

Oh, thanks! Yeah, I was involved here on the toolchain side. We did a lot of work on the Binaryen optimizer for WasmGC.

Rewriting a large codebase with many years of work behind it to a totally new language is a pretty big task, and often ends up introducing new bugs. But I do agree Java has downsides. A more practical conversion would be to Kotlin. That&#x2

Yes, that is correct. It began 2x slower than JS, and ended up 2x faster than JS.

by azakai 2y ago
The two posts make the most sense together, yeah. I was involved in this work (happy to answer any questions). Overall we started from a large slowdown compared to JS, worked hard, and ended up with a large speedup over JS of around 2x. So

You're right that LLMs don't have special insight into themselves, but on the other hand it is reasonable to assume they have been trained in order to properly describe themselves. That description isn't from insight but from

It is still largely automatic. Some amount of special annotations are needed in all these related approaches. For example, in this article, @CompilationFinal is used in Graal interpreters. (It is possible more annotations are needed in PyPy

PyPy has experimented with multiple approaches here, yes, but as far as I know they did not abandon the overall approach of automatically converting an interpreter to an optimizing VM, which is what I mentioned. That's more general tha

I am a big fan of automatically generating optimizing VMs from interpreters, like Graal (in this article) and also PyPy and others do. But the other approach, of writing a custom JIT for each language, seems much more flexible even if it is

It is similar to how much a student learns from working hard to solve a problem versus from being given the final solution. The effort to solve it yourself tends to give a deeper understanding and make it easier to remember. Maybe that&#x27

A big advantage of WasmGC is it would allow your binaries to be smaller, since you wouldn't need to bundle an allocator for heap::alloc and free. Kotlin and Java binaries can in some cases be be much smaller than C++ and Rust for that
