Toy-language-to-aarch64-jit progress: finally added function calls (including recursive calls)! To simplify adding function pointers later, I always load the address to a register and then jump to register (`blr` instead of `bl` instruction).

Toy-language-to-aarch64-jit progress: added floating-point support and (explicit) numeric conversions! Also there's built-in 16-bit float support since afaik it's supported by most desktop hardware anyway

Nomadic horse archers use a different way to hold the string of a bow while shooting (the Mongolian draw) compared to typical European / Middle Eastern infantry archers (the Mediterranean draw) which is especially well suited for horseback when you're wiggling up-down and generally rather unstable

Tried to make a "sad keanu" type photo but failed cause apparently sitting in a ton of snow actually makes me happy

Benchmarking time! Implemented is_prime function in C++ and in my toy language (the exact same algorithm), compiled with clang -O3 vs my jit-compiler. My codegen runs only 5x slower which is actually great, I expected much worse!

Toy-language-to-aarch64-jit progress: added function arguments (integers only though), branching and loops! It follows the standard Aarch64 C calling convention, so you can literally call it from C and it'll work.

A first beta of my 2D game library Karl2D is now available: github.com/karl-zylinsk...
It's raylib-like, written in Odin, has emscripten-free web builds and easy to modify.

Implemented variables in my toy-language-to-aarch64-compiler! Only integers for now, always 64-bit sized (even if the type is actually smaller), always on stack. Codegen is far from optimal but hey, at least it works!

Implemented logical ops and comparisons. Had to sprinkle extra sign/zero-extending instructions so that low-bitness (8/16/32) ops work correctly, since ARM doesn't have dedicated 8/16-bit registers (it has 32-bit but I'm not using them because I'm lazy)

I'm on vacation and I only have a Mac with me so naturally I'm slowly writing an actual JIT compiler for my toy language, casually fighting through ARMv8 ISA manual. Already got basic integer arithmetic working!
The 16-byte SP alignment rule caught me by surprise, ngl

Sometimes it's a good idea to look back and see how your project evolved. Tomorrow will be exactly 2 years since I've started, and I'm only about halfway there 😅

One thing I'm noticing here is that the game stopped looking cartoonish and started looking painterly. Which I guess aligns better with the final vision but I swear I didn't actually plan for that to happen

New blog post! (yep, at New Year's Eve.) A short detour into a fun one-liner shading model I use for clouds in my game 🥰

I have a genetic condition called "fissured tongue". (I'd post a photo but it's mildly disturbing; better google it.)
It's generally benign but makes my tongue hypersensitive to certain otherwise rather mild acids (tomatoes, kiwis, pineapples), strong tannings (walnuts), ...

Post a random fact about yourself:
I'm allergic to cold.
No, really. It's a thing, look it up.
Eating ice cream usually makes my lips break out in hives, but it's totally worth it.

I interned in the Licensing Dept at Marvel Comics my senior year in college, before Spider-Man or X-Men hit theaters. Got to see a very early cut of the Spider-Man trailer.

Suddenly remembered a project I was working on some...3 years ago? There's so much pixel art, and it's genuinely much better than I thought it was 😅

I just learned something that I want to share;
1. Create an invisible box with an outer shadow
2. Create an invisible box with an inner shadow
3. Place randomly...

I've unintentionally tried using comments in my toy language many times already, so I decided to finally add them (just single-line for now), turned out to be an almost trivial change to the lexer+parser

Added support for default zero-initialization in my toy language. Only works with structs & built-in types - can't zero-initialize function pointers or arrays for now (but probably will be able to in the future!). Not initializing a variable is always an error btw

Been mostly refactoring my toy language parser & interpreter lately. When I'm done, here's a rough outline of what I'm planning to add next to the language 😌

Funny animal videos no longer being trustworthy just fucking sucks all around. I love the wonder of animal behavior and what it says about the experience of being alive. It's because it happened in reality that it's so fun. It's not fun if it was just made up. There's no wonder there.

Played with hand-generating CPU instruction opcodes in properly compiling my toy language. Here's the code for a function that just negates an int 😅
Though I've realized that opcodes are the easy part! I also need conversion to SSA & register allocation & other stuff...
