This December, I'll be posting an article & video each day until Christmas in the Advent of Compiler Optimisations! #AoCO2025
Each day we'll explore a fun optimisation in C or C++; some low-level, x86 or ARM-specific, some high-level. Hope you'll join me!

Very sad news about Rainer, who passed away earlier this week. If you can help support #ALS research please consider donating.

My thoughts are with his family. We as a C++ community were lucky to have him.
