If a shader was bound to the fragment shader TGSI executor and it was
then deleted and a new shader was allocated at the same address as the
old shader, the new fragment shader would not get properly bound to
the TGSI machine and we'd wind up using the old one.
This would not have been a problem if shaders were refcounted.
Now the TGSI machine is owned by the context rather than the quad
pipeline's shader stage so that the softpipe_delete_fs_state()
function can access it.
Fixes sporadic failures of the piglit fp-long-alu test (fd.o bug 27989).
To properly execute an instruction such as "ADD tmp, tmp.wzyx, foo;"
with SOA we (sometimes) need to put the results into temporaries before
writing the results to the destination register.
This patch fixes the ADD instruction but this needs to be done for
many more instructions.
Helps to fix piglit fp-long-alu test (fd.o bug 27989).
This lets us unbind a shader from the tgsi_exec_machine. Since
shaders aren't ref counted we need this to properly clean up when
deleting shaders elsewhere.
When the mipmap level is smaller than the compression block width, height
we need to fill in / replicate pixels so that we don't get garbage values.
Fixes piglit gen-compressed-teximage test.
Saves some work and avoids potential issue with inconsistant mipmap
level sizes. As long as the mipmap levels from BaseLevel to MaxLevel
are consistant, we don't care about the other levels.
OpenGL occlusion queries work now. The Mesa demos, glean test and piglit
tests all pass. A few enhancements are possible in the future. -Brian

These files are built with make and removed with make clean, so it does not
seem necessary to track them.
Looking at the Makefile, it seems that the two u_indices_* files are handled
similarly to u_format_srgb.c u_format_table.c and u_half.c, and these 3
files are already untracked and in .gitignore

Builds on commit ddb0e18f6c and fixes
regressions in glean clipFlat test.
We assume that Gallium drivers observe flatshade_first for all triangles
and that all the assorted per-triangle calls in the 'draw' module also
follow flatshade_first. Everything else builds on those rules.
Gallium does not use follow flatshade_first for GL quads, quad strips
and polygons; the "last" vertex is always the provoking vertex for those
prims. So now there are separate QUAD_FIRST_PV and QUAD_LAST_PV macros
in the draw primitive decomposition code instead of one QUAD macro.
This prevents memory usage explosion in blender due to the state cache
hanging on to old fake frontbuffer regions. Sigh at blender still
using frontbuffer rendering.
Bug #24119.
Remember the size of the level=0 mipmap image. Do not call
util_format_get_component_bits when st_context_teximage is called to
release a texture image.
