I wanted to write a thoughtful article in response to Dominik Wagner’s “On my misalignment with Apple’s love affair with Swift” . During my research I realized, that Chris Lattner had already done this. Sort of. 17 months before Dominik published his piece.

Porting to GCC 14: C language issues
The GCC 14 release series differs from previous GCC releases in a number of ways . Some of these are a result of bug fixing, and some old behaviors have been intentionally changed to support new standards, or relaxed in standards-conforming ways to facilitate compilation or run-time performance.

Compiler Development: Rust or OCaml?
The question of which language suits best for compiler development is a frequent one amongst language enthusiasts (e.g., see discussions here , here , and here ). Sadly, most of the commenters either 1) just answer with their language of choice without any explanation, or 2) provide a vague explanation without any…

Compiling Java into native binaries with Graal and Mill
One recent development is the ability to compile Java programs into self-contained native binaries. This provides more convenient single-file distributions, faster startup time, and lower memory footprint, at a cost of slower creation time and limitations around reflection and dynamic classloading. This article…

Parameterized types in C using the new tag compatibility rule
C23 has a new rule for struct, union, and enum compatibility finally appearing in compilers starting with GCC 15, released this past April, and Clang later this year. The same struct defined in different translation units (TU) has always been compatible — essential to how they work. Until this rule change, each such…

Clojure: Transducers
Transducers are composable algorithmic transformations. They are independent from the context of their input and output sources and specify only the essence of the transformation in terms of an individual element. Because transducers are decoupled from input or output sources, they can be used in many different…

I wrote a 231-byte Brainfuck compiler by abusing everything
We wrote a Brainfuck compiler back in April . That one developed a simple architecture to support multiple backends. Today, I want to write a new Brainfuck compiler. One that can only run on a single system, OpenBSD /amd64. And one that is as small as I can possibly make it. I broke into the sub-256 bytes club with my…
