Re-reading discussions about WASM, some on the Dart GH repo, some on HN.
I really wish WASM was renamed to something like Virtual Assembly/VASM so we could totally silo discussions about the bytecode target from discussions about web. They're totally unrelated.

Outra coisa que eu achei ótima na pergunta da @maribedran.bsky.social é que explicita a parte compilada de python.
A resposta do @ramalho.org deixa claro que o compilador gera código pra transformar aquela função num gerador. Descompilando o bytecode isso fica óbvio:

Add more logs, exceptions even (to stop at a specific state). They run and show all is fine.
After I restart Ghidra the bug is gone.

i was just thinking about this a few days ago while playing with porting some bytecode vm stuff to gpu shaders... it doesn't sound like they're planning to work on hardware (yet?) which to me is the most limiting aspect of this whole problem space.

Automatic instrumentation can seem like magic—but it’s not!
The latest #OpenTelemetry blog breaks down how it really works, from monkey patching and bytecode instrumentation to eBPF and runtime APIs.

Demystifying Automatic Instrumentation: How the Magic Actually Works
Despite the rise of OpenTelemetry and eBPF, most developers don’t know what automatic instrumentation actually does under the hood. This post breaks it down—not to suggest you build your own, but to…

Yes! #MetaIR is getting into shape! Use the #java25 Class-File-API to load #jvm #bytecode and transform it into a universal compilable graph. MetaIR is extracted from #Bytecoder and will allow to cross-conpile #Java to #OpenCL and #WebAssembly. Checkout mirkosertic.github.io/MetaIR/de.mi...!

ocamlc is the bytecode compiler. ocamlopt technically does optimizations, but almost none and ocamlopt with flambda(2) is actually properly optimizing

Hmm, it almost feels like you could (in a stack machine where you don’t have to worry about register selection or whatever) build up a reasonably large collection of common idioms (that may be multiple bytecode instructions) and then just chain them together to reduce the amount of jumps required

Second: tuples!
I added a BUILD_TUPLE opcode, similar to BUILD_LIST.
Eventually I will load tuples directly into the bytecode as constants, but I didn't tackle that optimization yet.

أما #Python ، فهي مزيج من الطريقتين. يتم أولاً ترجمة الكود المصدر إلى Bytecode مستقل عن النظام الأساسي، والذي يتم تنفيذه بعد ذلك سطرًا بسطر بواسطة مفسر يعتمد على النظام الأساسي. بالإضافة إلى ذلك، تستخدم تطبيقات مثل PyPy الترجمة الفورية (JIT) لزيادة السرعة.

I'm not familiar with Lustre, but in a safepoint GC like ours having enough safepoints is a challenge: ATM we check for GC at each bytecode instruction and calling into JS requires allowing GC. Malicious code could go into a no-GC scope and perform limitless allocation but couldn't call into JS.
