Mesa was not expecting kernels to have multiple operands in the LLVM metadata nodes (and an attribute is represented as an additional metadata node). This led to memory corruption and an LLVM error. This patch fixes the piglit test case in <a href="attachment.cgi?id=101832" name="attach_101832" title="Test Case exposing the bug causing the luxrays crash">attachment 101832</a> <a href="attachment.cgi?id=101832&action=edit" title="Test Case exposing the bug causing the luxrays crash">[details]</a> on CEDAR (r600g), and it probably helps radeonsi as well (which I can test later). This same patch will be sent to the mesa-dev list momentarily.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
