Agreed in things of build-time.
There were some improvements and optimizations to LLVM/Clang but twice
as slow is really hard compared with GCC.

I was thinking more in the direction of "compatibility" of tip tree
with recent LLVM/Clang other than what is officially supported via
Kbuild-system.

Let me look if I will do a selfmade ThinLTO+PGO optimized LLVM
toolchain v12.0.0-rc3 this weekend.
