In order to track it down I added some debugging to mesa and could get the following trace that leads to the error: r600/r600_asm.c:615 check_and_set_bank_swizzle - Couldn't find a working swizzle drivers/r600/r600_shader.c:3975 tgsi_op2_s - Error in tgsi_op2_s, i = 3, r600_bytecode_add_alu returned -1 r600/r600_shader.c:3332 r600_shader_from_tgsi - Failed to build shader at ctx.inst_info->process, chip class: 6, opcode: 7 result: -1 Since I added output for every "return -1" in r600/r600_asm.c I also get a lots of other messages, but I guess that these are normal. Debugging the code I also found that check_and_set_bank_swizzle exiting with "Couldn't find a working swizzle" is not necessarily an error, which means that I'm now a bit lost, because I'm not sure about how continue debugging this problem.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
