I have to disagree, -flto=thin is faster in compile time, but in performance I get better results with -flto=n in GCC. Also with FDO I get better results with GCC over Clang/LLVM, my main test subjects are rendering (Blender), archivers, encoders and emulation. However with straight up -O2/-O3 I very often get better performance with Clang/LLVM. I haven't benchmarked on ARM though, my results may be very different there.
