Re: FreeBSD C compiler version

I would like to start a little discussion about FreeBSD build slave. As it turned out, every new commit is being checked on clang compiler too! It was a bit unexpectedly to me, because we already discussed about this in Gerrit: https://gerrit.osmocom.org/#/c/2100/ > Max: > > Do we officially support anything besides gcc? > > Harald: > > not really, but then it is also nice to be portable. My vote > > would be to merge the current patch under discussion, but open > > a ticket as a reminder that this should be made more portable. > > I suppose mplayer/ffmpeg/fftw or other libs with heavily > > optimized algorithms also have a solution to that. Recently I decided to dig into FreeBSD's world, because one of my changes in Gerrit does build fine on Debian slave, but doesn't on FreeBSD. So, I spent a whole night with my laptop and finally installed and configured FreeBSD first time in my experience. https://gerrit.osmocom.org/#/c/2100/ I am running 11.0 STABLE, and by default it comes with clang as default compiler. There is no GCC installed by default. I tried to build my change with different versions of clang and found the following interesting facts: - Recent clang-4.0 does support the __builtin_cpu_supports call, so runtime CPU detection should work in this case too. I don't know if it works in other versions. So, I suggest to add a new configure.ac task, which would check whether compiler supports this call or not. - Regarding to my change, it builds fine on several tested clang versions: clang-3.4.2, clang-3.9, clang-4.0. And I see two possible reasons, why the build fails on FreeBSD: 1) Version 3.4.1 is pretty dated, and we cat try to upgrade it. 2) Clang compiles the source code in a different way, when some SIMD flags are provided. But target CPU doesn't support some of provided SIMD flags. Now in both OsmoTRX and libosmocore we only check whether compiler supports some SIMD flags, but we don't check whether these flags are supported by current build machine CPU. So, lack of the last check and specific optimization / compilation way of clang may cause the fail. I still need to know supported SIMD features of FreeBSD build machine to confirm or refute this assumption. I also have an idea: what if we could build our projects with several compilers (GCC and clang) and with their several versions (the three latest for example) on Jenkins at the same time? I think, it would be great to keep our projects as portable as possible. With best regards, Vadim Yanitskiy.

Hi Alexander and all, > I don't think those patches will change this if your seeing a failure with > a --without-sse build. I hope, it should, because even with --without-sse we still had -march=native. http://git.osmocom.org/osmo-trx/commit/?id=78b5627fa1c911713a776e4aa1cb2d8f… Neels, do you still have the same problem with running on osmo-gsm-tester setup? With best regards, Vadim Yanitskiy.
