So I didn't touch r300compiler, but r300g now compiles after having
declarations and code untangled. As nha so gently points out, we shouldn't
have to do this just to comply with MSVC compilers.
So that debugging is no longer a full-spam-or-nothing approach, you are now
supposed to set the RADEON_DEBUG environment flag just like for classic Mesa.
The available debug flags are different, however. Just running an OpenGL
application with RADEON_DEBUG set to an arbitrary string will print out
helpful information.
Everything must be compiled with -DDEBUG for any of this to work
Appart from separating r3xx/r5xx fragment shaders, a more consistent
naming scheme has been applied. From now on:
r300 = all chips
r3xx = R300/R400 only
r5xx = R500 only
This way r300_fragment_shader is the master struct, and the structs
r3xx_fragment_shader and r5xx_fragment_shader inherits it.
