backtraces from bioshock
I have been trying to get the game Bioshock (running in Wine) to run with Mesa
drivers. The game will start, but when it's loading a map it just sits there,
pegging the CPU.
A backtrace seems to indicate that it's busy running the shader compiler.
Backtraces usually differs, but only up to a point, eventually they all point
back to do_common_optimization.
This might be a regression. The game was running at one point on r300g, but I
never made a note of the version of Mesa and Wine used, and so far haven't been
able to find a good starting point for a bisect. (Earlier versions of r600g
causes a GPU hang and AFAIK i965 have never worked with this game).
Setting MESA_GLSL="nopt" will cause a crash in the driver, "nopfrag" or
"nopvert" makes no difference on the bug, and using "dump" causes a crash in
hash_table_string_hash (might be separate bug?)
This is using Mesa 2fe39b46e73aea37152777fe11d489e0b1bc3f92 and Wine 1.3.22.
