Comment= # 3 on bug 99349<= /a> from Gert Wollny 
I've had the same error output when I was playing with the Unr=
eal Editor with
an HD6850  (BARTS) using the latest mesa-git.=20=20

In order to track it down I added some debugging to mesa and could get the=
=20
following trace that leads to the error:

r600/r600_asm.c:615=20
  check_and_set_bank_swizzle - Couldn't find a working swizzle

drivers/r600/r600_shader.c:3975=20
  tgsi_op2_s - Error in tgsi_op2_s, i =3D 3, r600_bytecode_add_alu returned=
  -1

r600/r600_shader.c:3332=20
r600_shader_from_tgsi - Failed to build shader at ctx.inst_info->process=
,=20
   chip class: 6, opcode: 7 result: -1

Since I added output for every "return -1" in r600/r600_asm.c I a=
lso get a lots
of other messages, but I guess that these are normal.=20

Debugging the code I also found  that check_and_set_bank_swizzle exiting wi=
th
"Couldn't find a working swizzle" is not necessarily an error, wh=
ich means that
I'm now a bit lost, because I'm not sure about how continue debugging this
problem.
