@prologic@twtxt.net Yeah, the parser part is what I typically enjoy. Haven’t really looked into code generation itself.

I’m currently looking at your µ commits from the last few days. Holy cow! :-)

Whoo! I fixed one of the hardest bugs in mu (µ) I think I’ve had to figure out. Took me several days in fact to figure it out. The basic problem was, println(1, 2) was bring printed as 1 2 in the bytecode VM and 1 nil when natively compiled to machine code on macOS. In the end it turned out the machine code being generated / emitted meant that the list pointers for the rest... of the variadic arguments was being slot into a register that was being clobbered by the mu_retain and mu_release calls and effectively getting freed up on first use by the RC (reference counting) garbage collector 🤦‍♂️

@shinyoukai@neko.laidback.moe Nah it’s more like there’s a lot of repeated code, because when you go from source language to intermediate representation to machine code, well you just end up writing a lot of the same patterns over and over again. I need to dedupe this I think.

@prologic@twtxt.net code generation on demand or something?

44% Of GNOME Core Apps Are Written In C, 13% In JavaScript & 10% In Rust
GNOME developer Sophie Herold has shared some interesting end-of-year code stats for the GNOME project. The “GNOME” codebase is up to 6,692,516 lines of code at the end of 2025 with 1,611,526 lines of that being from GNOME apps. Where the data gets interesting is on the programming language breakdown in different areas… ⌘ Read more

The compiler technique I’m using here is to not “emit” most of the runtime if it’s actually never used in your program, and also dropping dead code in the SSA pass.

Hmmm I need to figure out a way to reduce the no. of lines of code / complexity of the ARM64 native code emitter for mu (µ). It’s insane really, it’s a whopping ~6k SLOC, the next biggest source file is the compiler at only ~800 SLOC 🤔

@movq@www.uninformativ.de I think I can get binaries even smaller with a bit more work and effort 🤔 But yeah still working on the native code generation (at least for macOS targets)

@movq@www.uninformativ.de Oh that’s fine, Mu can compile to native code and so far binaries. at least on macOS are in the order of Kb in size 😂

FFmpeg Developer Files DMCA Against Rockchip After Two-Year Wait for License Fix

My little toy operating system from last year runs in 16-bit Real Mode (like DOS). Since I’ve recently figured out how to switch to 64-bit Long Mode right after BIOS boot, I now have a little program that performs this switch on my toy OS. It will load and run any x86-64 program, assuming it’s freestanding, a flat binary, and small enough (< 128 KiB code, only uses the first 2 MiB of memory).

Here I’m running a little C program (compiled using normal GCC, no Watcom trickery):

https://movq.de/v/b27ced6dcb/los86%2D64.mp4

Next steps could include:

• Use Rust instead of C for that 64-bit program?
  
• Provide interrupt service routines. (At the moment, it just keeps interrupts disabled.)

Cursor CEO Warns Vibe Coding Builds ‘Shaky Foundations’ That Eventually Crumble

LLVM Considering An AI Tool Policy, AI Bot For Fixing Build System Breakage Proposed
Last week a request for comments (RFC) was issued around establishing an LLVM AI Tool Use Policy.
