<div dir="ltr">Thanks for the replies. <div> </div><div>I tried to upgrade LLVM from 3.3 to 3.4 after I sent the e-mail but ended up having "an internal compiler error" from gcc linaro toolchain compiler. Nice. I could try a more up-to-date version of Mesa to see if it helps. Although I have learned that I can not take the most up-to-date version since something has gotten broken related to SW rendering/wayland/egl.</div><div> </div><div>Marko</div><div> </div><div> </div></div><div class="gmail_extra"> <div class="gmail_quote">On Wed, Apr 15, 2015 at 6:45 PM, Jan Vesely <<a href="mailto:jan.vesely@rutgers.edu" target="_blank">jan.vesely@rutgers.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, I can run arm llvmpipe glxgears on IFC6410 (Snapdragon 600 APQ8064, Krait 300) without problems. llvm 3.5 mesa 10.4.3 both are fedora 21 standard packages without modifications.
