To fix this, we need to modify the r600_llvm_gpu_string() function in r600_llvm.c to return "r600" for R600 chips. Then we need to add a processor type for it in Processors.td, and finally we need to handle the "r600" processor in AMDIL7XXDevice.cpp (No need to create a AMDIL6XXDevice class). For R600 mDeviceFlag should be 0. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
