Explore the inner workings of compilers in this 30-minute talk by Jared Shumway, Vice President of White Hat Cal Poly. Dive into the process of transforming text files into machine code, learn how compilers optimize code performance, and discover techniques for generating obfuscated binaries. Gain insights into the internals of optimizing compilers, including abstract syntax trees, intermediate representations, and various optimization techniques such as constant folding, strength reduction, and dead code elimination. Examine specific tools and projects that can enhance code security and efficiency.
