just a little update. Tested some other fedoras: Fedora 22 with llvm 3.8 is also slow with julia 0.5, whereas a fedora 24 branch with llvm 3.7 is faster on julia 0.5 compared to julia 0.4, as it should be (speedup from inner loop parts translated into speedup to whole function).
don't know if anyone cares about that... At least the latest version seems to work fine, hope it stays like this into the final fedora 24 On Friday, February 26, 2016 at 7:08:06 PM UTC+4, Johannes Wagner wrote: > > hey guys, > I just experienced something weird.
