There is one problem though.
You can’t see it.
Well, not directly at least. You’ll never find uOPs in the binary.
But! You can see the “shape” of it with performance tools…and there are subtle tells in the binary as well (hint, some nops).

We have just released a new CppCon 2025 Video!

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.

Blog: xania.org
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.

Hi @pjkrill - just a heads up, @CompileExplore is a grass roots user-created site, independent of anyone. That's why the site is "godbolt.org" - it's my domain, not MS! (ref: infoworld.com/article/404634… "... Microsoft introduced the Compiler Explorer,
Hey folks! @CompileExplore is free & open for everyone, but if you're planning to use our API for bulk executions though, please ping us! CE is a shared resource and heavy use can slow things down for the whole community. DM me to chat - happy to help work something out! :)
Check out this actual real usable test case ("test" but it does actually work and could be put in production code AFAICT) of using C++26's reflection with cross-language bindings!
Working example you can play with: godbolt.org/z/6Y17EG984
We got @CompileExplore running in @ladybirdbrowser!
More work is required to actually edit the code live on the site, but we can now load/compile programs and view their disassembly. So cool! 🤓

When @mattgodbolt, who helped the compiler community and low-level programming enthusiasts to a great extent with @CompileExplore (godbolt), talks about "What Every Programmer Should Know about How CPUs Work", it's a must-watch talk.

Some very very old @CompileExplore short links will stop working in August...this is one of the big reasons we implemented our own short link servixe

Some people have asked what changed about MS compilers on @CompileExplore and why, so I wrote a blog post explaining: xania.org/202407/msvc-on-ce
