post_scheduler clears interference set for reallocatable values when
the value becomes live first time, and then updates it to take into
account modified order of operations, but this was not handled properly
if the value appears first time as a source in copy operation.

Some inputs may be preloaded into predefined GPRs,
so we can't reallocate arrays with such inputs.

New disassembler is not completely isolated yet from further processing
in r600g/sb that is not required for printing the dump, so it has higher
probability to fail in case of any unexpected features in the bytecode.
This patch adds "sbdisasm" flag for R600_DEBUG that allows to use new
disassembler in r600g/sb for shader dumps when shader optimization
is not enabled.
If shader optimization is enabled, new disassembler is used by default.

Mesa build is too complex to rely on successful builds. On refactorings
it is always a good idea to use git grep to prevent missing cases:
$ git grep u_assembled_primitive
src/gallium/auxiliary/draw/draw_pt_fetch_shade_pipeline_llvm.c: u_assembled_primitive(in_prim);
The differences from the previous releases that affect st/egl are
- logging macros are prefixed with an 'A'
- dequeueBuffer() and enqueueBuffer() require an additoinal argument for
fence fd, acquired from libsync
Additionally, include gralloc_drm.h with extern "C".
The function returns the number of reduced/tessellated primitives for the
given vertex count.

Switch to '>=' for comparisons, and it becomes obvious that the comparison for

Move together (or add) functions to decompose/reduce/assemble a primitive,
give them consistent names, and document them. Add u_prim_vertex_count() so
that the vertex count information can be used elsewhere.
u_assembled_primitive() will be removed in a folow-on commit.

I need this so I can look at vec4 and fs registers' files from the same
.cpp file without namespaces. As far as I can tell we never rely on the
particular numerical values of the files, though I thought it sounded like
a good idea when doing the VS (it turns out having 0 be BAD_FILE is nicer).

The GPU apparently goes looking for constants even though there are no
shader stages enabled, and gets stuck because we haven't told it there are
no constants to collect. If any other user of the 3D pipeline had run
(even the Render accel of the X server!) since power on, then the in-GPU
constant buffers would have been set up with some contents we didn't use,
and we would succeed.

NOTE: This is a candidate for the stable branches.
We are already emitting a EVENT_TYPE_CACHE_FLUSH_AND_INV_EVENT packet
when this flush flag is set, so flushing the dest caches with a
SURFACE_SYNC should not be necessary.
The motivation for this change is that emitting a SURFACE_SYNC packet with
the CB bits set was causing compute shaders to hang on Cayman.

Remove all the glDraw* functions from the GLvertexformat structure.
The point of that dispatch struct is to handle all the functions which
dispatch differently depending on whether we're inside glBegin/End.
glDraw* are never allowed inside glBegin/End so we can remove those
entries.
This simplifies the code paths and gets rid of quite a bit of code.

If the currently compiled primitive state is PRIM_UNKNOWN we should
not return true from _mesa_inside_dlist_begin_end(). This lets us
simplify the calls to that function.
Note, the call to _mesa_inside_dlist_begin_end() in vbo_save_EndList()
should have probably been checking for PRIM_UNKNOWN too, but it wasn't.
So there's no code change change.

The old code didn't make sense. The clause in question did the

error.
