  • I deliberately tried with the non-benchmark of running the core regression tests, because I was curious about process startup as well as steady-state costs, and found something similar - current clang is slower than current gcc. I tried to install gcc-llvm from macports, in the hope that that would be a fairer comparison, but the port failed to compile, so I've not (yet) been able to see whether the gcc optimiser via LLVM is better than than gcc without the LLVM "overhead", and hence isolate the effects of clang/gcc from LLVM/not-LLVM.

    • I also wonder about gcc's new -fcreate-profile/-fuse-profile options. Might be worth a try... But ultimately I think a project like using LLVM has more legs than that one-off optimisation.
