I found it to spiral into complete nonsense a few times when I tested it out, but it's possible that was a bug in the provider

It should be pretty mature outside of Wasi. To be fair, there's really nothing that's super mature in terms of Wasi support, except maybe Wasmtime

maybe it implies some amount of "live to work" etymologically, but the word "living" in that context specifically refers to living in the financial sense (the act of living wouldn't really make sense in that sentenc

Optimizations like these are so cool. I love seeing higher level languages take advantage of their high level-ness

What do you mean outside of programmer control? What's stopping you from setting the stack size in the linker flags?

You’re missing the fact that the compiler isn’t forced to fill every register in the first place. If it was less efficient to use more registers, the compiler simply wouldn’t use more registers. The actual counter proof here would be that i

Started on a dependency-free (including manual object file creation, excluding manual linker) single-pass C compiler with a goal of it being self-hosting. Spawned after my previous project (single-pass Wasm JIT) started to plateau a bit and

Maybe, but from the author's description, it seems like the interpretation of intent that they want is to generally give the most information possible to the compiler, so it can do its thing. I don't see why the right high level l

> High level languages lack something that low level languages have in great adundance - intent. Is this line really true? I feel like expressing intent isn't really a factor in the high level / low level spectrum. If anything,

Been working on a single-pass WebAssembly JIT compiler (atm only guaranteed to work on M1 air), been super interesting learning and thinking through strategies to balance fast compilation & fast generated code. It's the fastest sin

for the average developer I think the killer feature is allowing you to query over whatever data you want (csv, json, parquet, even gsheets) as equals, directly from their file form - can even join across them

distributing the dispatch instructions lets the predictor pick up on specific patterns within the bytecode - for example, comparison instructions are probably followed by a conditional branch instruction

I think the most surprising part here is the gzipped-base64'd-compressed data almost entirely removes the base64 overhead.

It's in test262, so it basically has to be supported for the project to accomplish its goals.
