Hi, yesterday, I compiled a ThinLTO+PGO optimized LLVM toolchain version 12.0.0-rc1. The new LLVM toolchain reduces my build-time by approx. 1/3 - means in numbers 04:30 -> 03:15 [hh:mm]. While gasping through linux-kbuild mailing-list [1] today I found the video in [2] about TinyCC. I wanted to share that video with you... with no comments.
