Commen= t # 5 on bug 10827= 2 from Jan Vesely 
These look like two separate problems. The luxmark failure is =
known. Luxmark
requires more than 22 global buffers currently supported by radeonsi. witho=
ut
asserts (src/gallium/drivers/radeonsi/si_compute.c:298) it accesses the glo=
bal
buffer array out of bounds.
just bumping MAX_GLOBAL_BUFFERS to 32 allows luxmark to run, albeit still w=
ith
many incorrect pixels -- libclc rounding conversions are incorrect.



The second problem is harder to assess. since platform evaluation works OK =
with
clinfo. the failure seems to be in llvm initialization code. Is IndigoBench=
mark
linking to LLVM (directly or via OpenGL)? if yes, is it linked to the same
version as clover?
