Integrated assembler improvements in LLVM 19
Within the LLVM project, MC is a library responsible for handling assembly, disassembly, and object file formats. Intro to the LLVM MC Project, which was written back in 2010, remains a good source to understand the high-level structures. In the latest release cycle, substantial effort has been dedicated to refining…

Implementing the Goodfellow GANs paper
Generative Adversarial Networks (GANs), discovered by Ian Goodfellow in 2014, were an early method in the area of generative AI. I will focus on image generation as set out in the paper Generative Adversarial Nets 1 . This paper is the focal point of the post, I will guide you through the implementation of the paper…

How much memory does a graph take?
We need a fast way to query multiple potentially large sets of data on-demand at interactive speeds. Sometimes the easiest solution to a hard problem is to build the right tool for the job.

Move semantics in Rust, C++, and Hylo
I just finished reading the paper Borrow checking Hylo . It outlines the basic design of Hylo . Hylo is an early-stage programming language, but unlike other contenders of C++, it provides memory safety like rust. Specifically it merges rust’s borrow checking ideas into the framework of moveable value semantics (MVS)…

Bringing Faster Exceptions to Rust
Three months ago, I wrote about why you might want to use panics for error handling. Even though it’s a catchy title, panics are hardly suited for this goal, even if you try to hack around with macros and libraries. The real star is the unwinding mechanism, which powers panics. This post is the first in a series…

Well-Known Secrets of AmigaDOS
In keeping with the Commodore tradition of cost cutting, most consumer models of their Amiga line of computers came with severely watered down documentation. The Amiga 500 was an exception from this rule, but owners of later machines - such as the A1200 - may not have gotten any documentation for the command line part…

Bump Allocation: Up or Down?
Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions…
