--- Comment #2 from Paul Berry <stereotype441 at gmail.com> ---
When I wrote this patch series I checked on shader-db and there were no
differences on i965 hardware.  So I'm guessing this is due to an unantipicated
difference in how code generation works with the Radeon back end.

Arek, would it be possible to find a shader from pixmark_volplosion that
compiles to worse code after the patch, and upload both the shader source and
the resulting Radeon assembly code (both before and after)?  That would be very
helpful to me in figuring out what is going wrong.

Thanks.
