[#Compiler] Day 1 of #AoCO2025 Study Notes
While the original uses #CompilerExplorer, I wanted to replicate the analysis locally.
In this post, I have used #gcc, #clang, llvm-objdump and #LLDB to analyze.

RE: https://hachyderm.io/@mattgodbolt/115689717135274179
Another #AbsoluteBanger from @mattgodbolt's Advent of Compiler Optimisations, in which the compiler knows when to stop being clever because it knows modern CPUs with all their mad out-of-order pipelining jibber-jabber don't need any help - and he shows us a tool on #CompilerExplorer for looking into that. Read this one, but then watch the video too.

@uecker @Codeberg @mattgodbolt
Wat?As a Codeberg member myself, I checked your example here as well. The @compiler_explorer UI seems to handle the link just fine: if you click on the offered link, the raw file content is shown as you would expect. Then, the compiler is complaining about the file where the CE-internal machinery has supposedly put down the source text that it has downloaded from Codeberg.
So, there seem to be two different code paths in play. One, close to the UI, that works. And another one, hidden in the background, that doesn't.

More thanks to Matt Godbolt for today's episode of #AdventOfCompilerOptimisations, where the only horrors are in the tortured C code that gets turned into beautiful elegant assembler. The golden moment was the footnote alerting me to the existence of #CompilerExplorer's "optimisation pipeline explorer".

🥳🎉 In the dystopian wonderland of 2025, Compiler Explorer is the AI overlord, churning out 92 million compilations like it's flipping burgers 🍔. Who'd have thought a hacky weekend project would grow into Skynet's compiler? 🙃
