@nobled nobled mesa: add back glGetnUniform*v() overflow error reporting
The error was removed in:

commit 7199096
Author: Ian Romanick <ian.d.romanick@intel.com>
Date:   Tue Oct 18 16:01:49 2011 -0700

    mesa: Rewrite the way uniforms are tracked and handled

The GL_ARB_robustness spec doesn't say the implementation
should truncate the output, so just return after setting
the required error like it did before the above commit.

Also fixup an old comment and add an assert.

NOTE: This is a candidate for the 8.0 branch.

@anholt anholt i965/fs: Jump from discard statements to the end of the program when …
…done.

From the GLSL 1.30 spec:

     The discard keyword is only allowed within fragment shaders. It
     can be used within a fragment shader to abandon the operation on
     the current fragment. This keyword causes the fragment to be
     discarded and no updates to any buffers will occur. Control flow
     exits the shader, and subsequent implicit or explicit derivatives
     are undefined when this control flow is non-uniform (meaning
     different fragments within the primitive take different control
     paths).

v2: Don't emit the final HALT if no other HALTs were emitted.

@krh krh shared-glapi: Convert to automake
This fixes a build problem where EGL links to libgbm.la, which encodes

of src/gbm.  Typically we silently fall back to the system
libglapi.so, which is wrong and breaks when there isn't one.

We want to start emitting an INVALID_OPERATION from here for transform

Brian Paul mesa: rework texture completeness testing
Instead of gl_texture_object::_Complete there are now two fields:
_BaseComplete and _MipmapComplete.  The former indicates whether the base
texture level is valid.  The later indicates whether the whole mipmap is
valid.

With sampler objects, a single texture can appear to be both complete and
incomplete at the same time.  See the GL_ARB_sampler_objects spec for more
details.  To implement this we now check if the texture is complete with
respect to a sampler state.

Another benefit of this is we no longer need to invalidate a texture's
completeness state when we change the minification/magnification filters
with glTexParameter().

@kaydenl kaydenl glsl: Make ir_dereference_array constructor assert the variable exists.
Providing a NULL pointer to the ir_dereference_array() constructor seems
like a bad idea.  Currently, if provided NULL, it returns a partially
constructed value of error type.  However, none of the callers are
prepared to handle that scenario.

Code inspection shows that all callers do one of the following:
- Already NULL-check the argument prior to creating the dereference
- Already deference the argument (and thus would crash if it were NULL)
- Newly allocate the argument.

Thus, it should be safe to simply assert the value passed is not NULL.
This should also catch issues right away, rather than dying later.

@kaydenl kaydenl glsl: Split up function matching and call generation a bit more.
We used to have one big function, match_signature_by_name, which found
a matching signature, performed out-parameter conversions, and generated
the ir_call.  As the code for matching against built-in functions became
more complicated, I split it internally, creating generate_call().

However, I left the same awkward interface.  This patch splits it into
three functions:
1. match_signature_by_name()

   This now takes a name, a list of parameters, the symbol table, and
   returns an ir_function_signature.  Simple and one purpose: matching.

2. no_matching_function_error()

   Generate the "no matching function" error and list of prototypes.
   This was complex enough that I felt it deserved its own function.

3. generate_call()

   Do the out-parameter conversion and generate the ir_call.  This
   could probably use more splitting.

The caller now has a more natural workflow: find a matching signature,
then either generate an error or a call.

@kaydenl kaydenl glsl: Use ir_rvalue to represent generic error_type values.
Currently, ir_call can be used as either a statement (for void
functions) or a value (for non-void functions).  This is rather awkward,
as it's the only class that can be used in both forms.

A number of places use ir_call::get_error_instruction() to construct a
generic value of error_type.  If ir_call is to become a statement, it
can no longer serve this purpose.

Unfortunately, none of our classes are particularly well suited for
this, and creating a new one would be rather aggrandizing.  So, this
patch introduces ir_rvalue::error_value(), a static method that creates
an instance of the base class, ir_rvalue.  This has the nice property
that you can't accidentally try and access uninitialized fields (as it
doesn't have any).  The downside is that the base class is no longer
abstract.

@kaydenl kaydenl glsl: Convert ir_call to be a statement rather than a value.
Aside from ir_call, our IR is cleanly split into two classes:
- Statements (typeless; used for side effects, control flow)
- Values (deeply nestable, pure, typed expression trees)

Unfortunately, ir_call confused all this:
- For void functions, we placed ir_call directly in the instruction
  stream, treating it as an untyped statement.  Yet, it was a subclass
  of ir_rvalue, and no other ir_rvalue could be used in this way.
- For functions with a return value, ir_call could be placed in
  arbitrary expression trees.  While this fit naturally with the source
  language, it meant that expressions might not be pure, making it
  difficult to transform and optimize them.  To combat this, we always
  emitted ir_call directly in the RHS of an ir_assignment, only using
  a temporary variable in expression trees.  Many passes relied on this
  assumption; the acos and atan built-ins violated it.

This patch makes ir_call a statement (ir_instruction) rather than a
value (ir_rvalue).  Non-void calls now take a ir_dereference of a
variable, and store the return value there---effectively a call and
assignment rolled into one.  They cannot be embedded in expressions.

All expression trees are now pure, without exception.

Yuanhan Liu i915: set SPRITE_POINT_ENABLE bit correctly
When SPRITE_POINT_ENABLE bit is set, the texture coord would be
replaced, and this is only needed when we called something like
glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE).

And more,  we currently handle varying inputs as texture coord,
we would be careful when setting this bit and set it just when
needed, or you will find the value of varying input is not right
and changed.

Thus we do set SPRITE_POINT_ENABLE bit only when all enabled tex
coord units need do CoordReplace. Or fallback is needed to make
sure the rendering is right.

With handling the bit setup at i915_update_sprite_point_enable(),
we don't need the relative code at i915Enable then.

This patch would _really_ fix the webglc point-size.html test case and
of course, not regress piglit point-sprite and glean-pointSprite
testcase.

NOTE: This is a candidate for stable release branches.

v2: fallback just when all enabled tex coord units need do

@stereotype441 stereotype441 i965: Stop lying about cpp and height of a stencil buffer.
When using a separate stencil buffer, i965 requires that the pitch of
the buffer (in the 3DSTATE_STENCIL_BUFFER command) be specified as 2x
the actual pitch.

Previously this was accomplished by doubling the "cpp" and "pitch"
values stored in the intel_region data structure, and halving the
height.  However, this was confusing, and it led to a subtle (but
benign) bug: since a stencil buffer is W-tiled, its true height must
be aligned to a multiple of 64; we were accidentally aligning its faux
height to a multiple of 64, causing memory to be wasted.

Note that for window system stencil buffers, the DDX also doubles the
cpp and pitch values.  To facilitate fixing this DDX server bug in the
future, we fix the cpp and pitch values we receive from the X server
only if cpp has the "incorrect" value of 2.

    Date:   Fri Mar 16 12:55:40 2012 -0400

    shared-glapi: Convert to automake

The offending change was that it redefined the filepaths in sources.mak
like this:
    - FOO_FILES := bar.c
    + FOO_FILES := $(TOP)/src/mapi/mapi/bar.c
This broke the build because source filepaths in Android makefiles must be
relative to the makefile.

Ideally, this could be fixed by reverting the change in sources.mak and
making shared-glapi's Makefile.am use $(addprefix $(TOP)/src/mapi/mapi,
$(FOO_FILES)). However, automake doesn't understand builtin GNU make
functions, such as addprefix. So, it seems that automake and Android can
no longer share sources.mak.

Fix the build by duplicating the source lists from sources.mak into
Android.mk.

@anholt anholt glsl: Don't apply optimization passes to builtins.
The builtins we have are generally optimized, having been
hand-written.  This avoids generating bad code when an optimization
pass prints debug output.
fda662f
@anholt anholt glsl: Add an array splitting pass.
I've had this code laying around almost done for a long time.  The
idea is like opt_structure_splitting, that we've got a bunch of
transforms at the GLSL IR level that only understand scalars and
vectors, which just skip complicated dereferences.  While driver
backends may manage some optimization after they split matrices up
themselves, it would be better to bring all of our optimization to
bear on the problem.

While I wasn't expecting changes quite yet, a few programs end up
winning: a gstreamer convolution shader, and the Humus dynamic
branching demo:
Total instructions: 269430 -> 269342
3/2148 programs affected (0.1%)
1498 -> 1410 instructions in affected programs (5.9% reduction)
60177d5
@anholt anholt glsl: Extend the array splitting optimization pass to matrices.
This should fit in well with our lower_mat_op_to_vec code: now, in
addition to having expressions on each column of a matrix, we also
split the columns to separate variables so they can be tracked
individually by the copy propagation, dead code, and other passes.

This optimizes out some more code generation in unigine and gstreamer
shaders.

Total instructions: 269342 -> 269270

179386 -> 172765 instructions in affected programs (3.7% reduction)

v2: Move some of the logic of finding the instruction that produced

32ae8d3
@anholt anholt i965/fs: Avoid generating extra AND instructions on bool logic ops.
By making a bool fs_reg only have a defined low bit (matching CMP
output), instead of being a full 0 or 1 value, we reduce the ANDs
generated in logic chains like:

   if (v_texcoord.x < 0.0 || v_texcoord.x > texwidth ||
       v_texcoord.y < 0.0 || v_texcoord.y > 1.0)
      discard;

My concern originally when writing this code was that we would end up
generating unnecessary ANDs on bool uniforms, so I put the ANDs right
at the point of doing the CMPs that otherwise set only the low bit.
However, in order to use a bool, we're generating some instruction
anyway (e.g. moving it so as to produce a condition code update), and
those instructions can often be turned into an AND at that point.  It
turns out in the shaders I have on hand, none of them regress in
instruction count:

Total instructions: 262649 -> 262545
39/2148 programs affected (1.8%)
14253 -> 14149 instructions in affected programs (0.7% reduction)

@bpeel bpeel wayland-drm: Implement wl_buffer.damage in old versions of Wayland
Commit 272bc48 removed the damage implementation for the
wl_buffer_interface because that has been removed from git master of
Wayland. However this breaks building with the 0.85 branch of Wayland
because it would end up initialising the struct incorrectly.

For the time being it's quite convenient for some compositors to track
the 0.85 branch of Wayland because the protocol is stable but they
will also want to track the master branch of Mesa so that they can use
the gbm surface changes.

This patch adds a compile-time check for the version of Wayland so
that it can work with either Wayland master or the 0.85 branch.

krh: Edited to also account for API changes in 6802eaa68, which
removes the timestamp argument from wl_resource_destroy().

Ben Skeggs nouveau/vieux: switch to libdrm_nouveau-2.0 7e99c2b
Ben Skeggs nouveau: rework and simplify nv04/nv05 driver a bit
TEXTURED_TRIANGLE and MULTITEX_TRIANGLE are both a bit special in that if
you use any other graph object in the meantime they'll forget their state
and spew a lovely METHOD_CNT error at you when you try to draw.

The pre-newlib driver has a flush_notify() hook which does this state
re-emit, and a number of random workarounds like extra flushes and state
dirtying after various operations to solve this issue.

I'm taking a slightly different approach to things instead, which has the
nice side-effect of removing the divergent code-paths for ttri/mtri, the
flush/dirty workarounds and the need for flush_notify.  Also gives a few
FPS boost in OA, yay.

Ben Skeggs nvfx: completely remove this driver (GeForce FX/6/7)
This driver hasn't been maintained properly for a very long time, and for
many very good reasons.  It's horrible.

A new driver supporting these chipsets will appear with the commits that
port vieux/nv50/nvc0 to libdrm_nouveau-2.0.

Ben Skeggs nv30: import new driver for GeForce FX/6/7 chipsets, and Quadro variants
The primary motivation for this rewrite was to have a maintainable driver
going forward, as nvfx was quite horrible in a lot of ways.

The driver is heavily based on the design of the nv50/nvc0 3d drivers we
already have, and uses the same common buffer/fence code.  It also passes
a HEAP more piglit tests than nvfx did, supports a couple more features,
and a few more to come still probably.

The CPU footprint of this driver is far far less than nvfx, and translates
into far greater framerates in a lot of applications (unless you're using
a CPU that's way way newer than the GPUs of these generations....)

Basically, we once again have a maintained driver for these chipsets \o/

Feel free to report bugs now!
