Assembly Optimization Tips by Mark Larson (2004) (masm32.com)
The most important thing to remember is to TIME your code. Trying different tricks might or might not speed up your code. So it is very important to time your code to see if you do get a speedup as you try each trick.

Why those particular integer multiplies? (wordpress.com)
The x86 instruction set has a somewhat peculiar set of SIMD integer multiply operations, and Intel’s particular implementation of several of these operations in their headline core designs has certain idiosyncrasies that have been there for literally over 25 years at this point.

Implementing and Detecting Anti-Debugging with Fork() (netlify.app)
As I continue my journey into reverse engineering macOS and iOS applications, I’m currently focusing on ARM assembly. I’m also working on a follow-up to my previous post on reverse engineering. In this next post, I’ll be tackling the challenge of cracking a macOS app’s license, and since I’ll be dealing with a release build, assembly language will be essential.

Writing a Lisp compiler (Lisp to assembly) from scratch in JavaScript (2018) (eatonphil.com)
In this post we'll write a simple compiler in Javascript (on Node) without any third-party libraries. Our goal is to take an input program like (+ 1 (+ 2 3)) and produce an output assembly program that does these operations to produce 6 as the exit code. The resulting compiler can be found here.

SectorC: A C Compiler in 512 bytes (2023) (xorvoid.com)
SectorC (github) is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.
