BUILD_BUG(9)

✨ NAME ✨

okay so bestie, this is BUILD_BUG(9) from the Kernel API Manual 💖 and it's giving very simple, very iconic: BUILD_BUG — break compile if used. like, if it gets used, the compile literally breaks. periodt.

🦋 SYNOPSIS 🦋

BUILD_BUG

💅 DESCRIPTION 💅

so here's the vibe: if you have some code that you expect the compiler to eliminate at build time, you should use BUILD_BUG to detect if it is unexpectedly used 🫶 that's the whole thing. the compiler is supposed to yeet that code at build time, and BUILD_BUG is your little vibe check for when it gets used anyway 😭 no cap.
