DFC shader dump produced with R600_DEBUG=fs,vs,gs,ps,cs,tcs,tes
Since the release of book five of "Dreamfall Chapters: The longest Journey" and
their switch to a OpenGL 4.1+ context I'm getting the following error on load:
<span class="quote">> LLVM triggered Diagnostic Handler: Illegal instruction detected: Illegal immediate value for operand.
> LLVM failed to compile shader
> radeonsi: can't create a shader</span >
with the stack detailed below.
The game loads and book five is entirely playable. However almost all scenes
show minor visual corruption in the form of wrongly coloured pixels (not sure,
if the shader failing is responsible for that or if it's a different bug).
Usually in a very noticeable bright green (#0f0), but some other colours are
also observable (blue, yellow, red and few white and black ones as well). There
is only one scene during the epilogue where the character of Zoë Castillo is
shown sitting on a balcony where a large part of the background shows wrong
colours (I would assume it should be metallic roofs reflecting sunlight but
instead they are just plain yellow and red where the light hits).
Attached to this bug you'll find a shader dump produced with
R600_DEBUG=fs,vs,gs,ps,cs,tcs,tes passed to the game. The dump is intermixed
with what the game/Unity3D wrote to STDERR. In fact this is identical to
Unity's Player.log. In lines 119284-119286 you'll find the error message quoted
above. Since the full log was several MBytes in size I compressed it with xz.
The stack used was (Debian testing, fully updated, as a base):
