Is gcc really starting to fade away? Wasn't Rust working on some backend interop with it? That shiny cool Cosmopolitan thingie was also built on top of it IIRC.

I was also under the impression GCC still outputs better asm than LLVM overall.

Conversely, I recall reading the zig team ran into some woes with the latest LLVM release, and that there's a lot of churn in LLVM APIs from version to version.

(I'm legitimately curious)
