Matt Godbolt's blog post on #inlining reads like a desperate attempt to make compiler optimizations sound thrilling 😴. Spoiler: it's not. Inlining is to coding what counting calories is to dieting—important, but nobody wants to hear you talk about it for 16 days 🍕🔧.

Also, if you happen to have binaries compiled with and without Hot/Cold splitting, could you please share them?

Is Hot/Cold Splitting finally implemented in #LLVM? Do you happen to know how can I use it?

I know nobody gives a fuck, but this is my next research topic for this year: Finding #bugs & #vulnerabilities by #diffing binaries against sources. It sounds much harder than it actually is.
