Day 6 of Advent of Compiler Optimisations! Divide by 512—just a shift, right? But the compiler adds extra instructions. Why? A subtle difference between what you asked and what you meant! https://t.co/HMGZcHobXW https://t.co/lCXOhYAlbi #AoCO2025

Day 5 of Advent of Compiler Optimisations! x86 has LEA, but ARM has the barrel shifter—instructions can shift operands cheaply. The compiler uses this to multiply without multiplying! https://t.co/ajsfDk5k9E https://t.co/1FIAhXF2Oy #AoCO2025

Day 4 of Advent of Compiler Optimisations! Multiply by constants—which ones use actual multiply? The compiler has tricks to avoid it, then saves you from your own clever hacks. https://t.co/7AnyYnerRU https://t.co/N6aeoMPaIB #AoCO2025

Day 3 of Advent of Compiler Optimisations! A while loop, recursion, direct addition—all compile to one instruction. The compiler sees the pattern beneath the code. https://t.co/luClBW7dZt https://t.co/D90XnAoHVO #AoCO2025

Day 2: Adding two integers on x86? Not with `add`! The compiler uses a completely different instruction—one designed for memory addressing. Why? https://t.co/iXXyjWFLDF https://t.co/4VCDMAdBzn #AoCO2025

Ever wonder why compilers use `xor eax, eax` to zero registers? It's smaller AND faster—CPUs optimise it out entirely! Day 1 of Advent of Compiler Optimisations: https://t.co/VOo6hv2rEX Video: https://t.co/Kcqj07D5Ve #AoCO2025

My Advent of Compiler Optimisation starts tomorrow! Subscribe so you don't miss one! (Blog has RSS, YouTube subscription works too, all YTs link to blog and video versa) Starts at 13:00 UTC if I wake up in time!

@FelixCLC_ hey i use one of those mugs in my videos haha

I'm not good at this marketing lark, but as it's black friday and I'm inundated with other people's offers... You can get 10% off CE swag today with code BLACKFRIDAY :) https://t.co/nqqhSLGveb Makes a great present too!

“Assembly isn’t dead - just specialized.” @mattgodbolt and Dan Kusswurm explore modern x86 coding, when assembly is worth it, and how it can deliver up to 100x speedups for critical tasks. https://t.co/0pzGzHpI1A

This also is a fund raiser for @CompileExplore ! https://t.co/605L0LxyQf to get cool CE stuff!

This December, I'll be posting a blog & 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, some high-level. YT: https://t.co/cbSqouWa5p Blog:

I'll be chatting with @CompileExplore 's first ever sponsor, Solid Sands in around 30 minutes, about how we met, our backgrounds, and what we've been up to. Please drop in and say hi:

New Podcast Episode: @mattgodbolt is back after 5 years! And he's sharing stories about breaking through abstractions. Sometimes your “disk write” is a network hop in a trench coat, and your “fast path” hides a page fault. Godbolt's rule will help.

And for the final day of #Croctober, we’ve got some exciting news! 👀 The Game Boy Color version of Croc is now available to preorder for the Chromatic from ModRetro 🥳 https://t.co/HAQteXkfgj @modretro #chromatic #retrogaming

Croc Lead Programmer Tony Lloyd reflects on the game and the incredible lengths the team went to bring it to life. 🐊 Want more behind-the-scenes stories? Explore the full set of developer interviews in the Crocipedia section of Croc Legend of the Gobbos.

Colleges do a terrible job of teaching C++. It’s not “C with Classes”. Injected into curriculums as a demonstration of early CS concepts, it leaves many with a sour taste. Students later immediately fall in love with the first language that *doesn’t* feel that way.
