[Mesa-dev] [PATCH 1/3] r600g: increase array size for shader inputs and outputs

[Marek Olšák]

glsl-max-varyings uses 33 vertex shader outputs, but you need to be
lucky to see any difference. In my case, there was a weird assertion
failure during command buffer generation for a vertex shader (valgrind
didn't help). I found the cause by moving the input and output arrays
to the end of r600_shader and moving the r600_shader structure to the
end of r600_pipe_shader, whïch resulted in an expected segfault.
