This chip does have NEON instructions right? I think llvm used to have quite some problems if it needed to lower all the vector code to scalars (not to mention the horrific performance). Theoretically llvmpipe should work pretty ok on arm (albeit there's no arm specific optimizations, so slower than possible) but there were spurious reports of it not working well earlier (not many people try, it seems). It could also well be a llvm bug, I'd suggest a newer version if you're not already using the latest.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
