you're running llvmpipe though, the code will use runtime detection<br> of features for generated code. I have no idea if that code there<br> causing the crash was runtime-compiled by llvm or not. If yes, it could<br> mean there's still bugs with llvm and cpu detection features (detecting<br> this is quite a mess due to the OS having to support it). Albeit your<br> cpu features make no sense at all, you cannot have avx2 but not avx (and<br> you don't have the newer sse flags neither, even for a virtual cpu that<br> is pretty odd supporting avx2 but not these...).<br> Interestingly, xsave isn't listed neither, which is necessary for avx to<br> indicate the OS supports it, suggesting your OS does not. No idea why...<br> <br> Roland<br> <br> <br> <br> ><br> > Thanks<br> ><br> ><br> > MiningMath Associates<br> > <<a href="http://www.miningmath.com/component/content/article/4.html?src=ass&mdm=email&cpn=FAC#Fabr%C3%ADcio+Ceolin" rel="noreferrer" target="_blank">http://www.miningmath.com/<wbr>component/content/article/4.<wbr>html?src=ass&mdm=email&cpn=<wbr>FAC#Fabr%C3%ADcio+Ceolin</a>><br> > *Fabrício Ceolin*<br> > <a href="tel:%2B55%20%2831%29%2098675-1359" value="+5531986751359">+55 (31) 98675-1359</a><br> > MiningMath Associates <<a href="http://www.miningmath.com/?src=ass&mdm=email&cpn=FAC" rel="noreferrer" target="_blank">http://www.miningmath.com/?<wbr>src=ass&mdm=email&cpn=FAC</a>><br> > <a href="http://www.miningmath.com" rel="noreferrer" target="_blank">www.miningmath.com</a> <<a href="http://www.miningmath.com/?src=ass&mdm=email&cpn=FAC" rel="noreferrer" target="_blank">http://www.miningmath.com/?<wbr>src=ass&mdm=email&cpn=FAC</a>><br> ><br> ><br> ><br> ><br> ><br> > ______________________________<wbr>_________________<br> > mesa-dev mailing list<br> > <a href="mailto:mesa-dev@lists.freedesktop.org">mesa-dev@lists.freedesktop.org</a><br> > <a href="https://lists.freedesktop.org/mailman/listinfo/mesa-dev" rel="noreferrer" target="_blank">https://lists.freedesktop.org/<wbr>mailman/listinfo/mesa-dev</a><br> ><br> <br> </blockquote></div><br></div>
