The pi has a soc with armv6 (i don't know what that means exactly though).</div><div>The pi is not fast and llvm with clang compilation took 22 h, but worked. hurrah.</div><div>Then i compiled llvm/clang with itself and was pleased it took "only" 12 hours. even better.</div><div><br></div><div>But then I compiled linpack and clang numbers were less than 1/4 off gcc compiled :-( (9000kFlops about)</div><div><br></div><div>Now according to this <a href="http://elinux.org/RPi_Performance">http://elinux.org/RPi_Performance</a> there is something with compiler settings, hard/soft floats and possibly the exact target (armv6XXX) of the pi to make it better.</div><div><br></div><div>My question is: has anybody else tried this, or could tell me what i could try to remedy this.</div><div><br></div><div>Thanks</div><div><br></div><div>Torsten</div></body></html>
