GRID Autosport crash report

Hello,

On loading screen just before starting a race, the game crash to the desktop
with this on the terminal:

EE r600_shader.c:182 r600_pipe_shader_create - translation from TGSI failed !
EE r600_state_common.c:826 r600_shader_select - Failed to build shader variant
(type=1) -1

i added a crash report from the game .dmp, if it can help.



it was working on low setting with a previous version of mesa, i don't know the
exact version number but it was just before r600 add full support for OpenGL
4.1 and probably the tesselation. 


Here are the information about the version i currently use and make the game
crash just before the race start:

You might try running with ST_DEBUG=tgsi -- should show the failing shaders.
Make sure you're on a debug build. MESA_GLSL=dump should be interesting too.
[Sadly there's a 4k limit on the dumped shader code size which is likely too
short for a lot of shaders...]

it look like to hapened at shader compiling time.

Each time i have a crash there are new shaders in the bin directory of the
game.

And then after some crash i have all the shaders needed by the game to play the
race, but the game is still crashing on benchmark and totally freeze the
computer on replay with the cockpit view.

i made 3 differents attachements, i hope there is something interesting with
them.

The errors relating to r600 indicate it's having trouble converting some TGSI
shader. However those don't appear to be printed without --enable-debug. I've
pushed out a fix for another assertion, so try a mesa git head build (make sure
it includes commit eca8f38dcffb7), with --enable-debug, and run with
ST_DEBUG=tgsi -- that should hopefully show which shader r600 is having trouble
compiling.

Yesterday after compiling mesa with your commit, all was working fine on the
lowest setting, but it was still crashing with cockpit view on replay with low
setting.

This morning i made another mesa compilation because it was missing
--enable-debug and now the game stop at launch screen with:

There is 5 new commit since yours and one have modification on shaders so maybe
it's related.

I think it's not related at all with other commits, after reverting back is
still not launching anymore.

I found that with R600_DEBUG=nosb the game launch and do not crash with any
setting i choose.

With this setting I was finally able to complete the games benchmark! :)

Maybe it would be a good idea for you to take the offer from
https://bugs.freedesktop.org/show_bug.cgi?id=93352#c20 ("Please let us know if
we can assist by providing people working on driver issues a copy of the
title") - I'm sure this will speed up debugging a lot.

Not that this is the proper channel for this, but I replied to that offer here:
