So when you say that there are no debug symbols for the JITted code. that does not make sense for most(all?) people thus they assume the closest thing. Which is that you're missing the debug symbols, therefore giving you instructions on how to get them(rebuild mesa).
So can you please tell us what makes you think that using the i965 driver, goes into LLVM/JITted code ? Perhaps having some sort of backtrace (I know the some functions names will be ??) or a testcase might bring some light :) Cheers, -Emil > Thank you, > Steven Stewart-Gallus _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
