This doesn't quite make depth-tex-compare work, presumably because we're
not hitting equality with itof(sample) * 1.0/0xffffff in the 0xffffff
case. arb_fragment_program_shadow tests pass, though, as well as a bunch
of other shadow-related stuff.
We potentially need to be careful that use of a value stored in r4 isn't
copy-propagated (or something) across another r4 write. That doesn't
appear to happen currently, and this makes the dataflow more obvious. It
also opens up not unpacking the r4 value, which will be useful for depth
textures.
Since software primitive-restart emulation is going to be removed (and
anyways, mostly seemed to be crash prone in combination with
u_primconvert and oddball scenarios (like PIPE_PRIM_POLYGON with only a
single vertex), might as well do it in hardware (which fortunately
didn't turn out to be too hard to figure out).

Triggered by shaders like:
FRAG
PROPERTY FS_COLOR0_WRITES_ALL_CBUFS 1
DCL OUT[0], COLOR
DCL CONST[0]
DCL TEMP[0..2], LOCAL
0: IF CONST[0].xxxx :0
1: MOV TEMP[0], TEMP[1]
2: ELSE :0
3: MOV TEMP[0], TEMP[2]
4: ENDIF
5: MOV OUT[0], TEMP[0]
6: END
not really a sane shader, although driver segfaulting is probably
not the appropriate response.

We currently aren't too clever about dealing with running out of
cmdstream buffer space. Since we use a single buffer for both drawing
and tiling commands, we need to ensure there is enough space at the tail
of the cmdstream buffer to fit the tiling commands.
Until we get more clever, the easy solution is a threshold to trigger
flushing rendering even if the application does not trigger flush (swap,
changing render target, etc). This way we at least don't crash for apps
that do several thousand draw calls (like some piglit tests do).

Most of the things the new compiler still has trouble with basically
amount to cp stage removing too many copies. But without the cp stage,
the shaders the new compiler produces are still better (perf and
correctness) than the old compiler. So a simple thing to do until I
have more time to work on it is first trying falling back to new
compiler without cp, before finally falling back to old compiler.

Excess conversions considered harmful.
Recently Matt reworked the boolean uniform handling to use the value of
UniformBooleanTrue, rather than integer 1, when uploading uniforms:
mesa: Upload boolean uniforms using UniformBooleanTrue.
glsl: Use UniformBooleanTrue value for uniform initializers.
Marek then set the default to 1.0f for drivers without native integer
support:
mesa: set UniformBooleanTrue = 1.0f by default
However, ir_to_mesa was assuming a value of integer 1, and arranging for
it to be converted to 1.0f on upload. Since Marek's commit, we were
uploading 1.0f = 0x3f800000 which was being interpreted as the integer
value 1065353216 and converted to float as 1.06535322E9, which broke
assumptions in ir_to_mesa that "true" was exactly 1.0f.

Mesa already defines _GNU_SOURCE for glibc based systems and defining
_GNU_SOURCE will break the Mesa build on other systems such as OpenBSD.
_GNU_SOURCE only seems to be included in llvm-config output when
LLVM is built via autoconf and not when it is built by cmake.

With the gallium megadrivers we've converted most ST to optionally
use either statically linked in or shared pipe-drivers.
The hardcoded switch forgot to conditionally enable the build of the
shared pipe-drivers which resulted in them being constantly build.

Just drop the conditional and simplify our build. This means that
it'll build every time, but it does not require any dependencies nor
does it take that long to compile 200 lines of boilerplate code.

With recent commit we removed the NEED_NONNULL_WINSYS checks when
selecting the hardware (inc svga) winsys. svga has only one winsys
that explicitly requires libdrm (via it's bundled version of
vmwgfx_drm.h) but configure.ac never really checks for it.
Add the check early to prevent people from shooting themselves when
they select the driver but lack libdrm.

The rest of stencil handling isn't done yet, but it documents an extra
cl_u8(0) and helps make it obvious why we don't need to format clear_depth
the same way the depth/stencil buffer is formatted.
For now it still requires the color buffer to be present -- we're relying
on the store of color buffer contents to end the frame, and we have to do
something with color buffers in the rendering config packet.
According to GLSL-ES Spec(i.e. 1.0, 3.0), gl_Position value is undefined
after the vertex processing stage if we don't write gl_Position. However,
GLSL 1.10 Spec mentions that writing to gl_Position is mandatory. In case
of GLSL-ES, it's not an error and atleast the linking should pass.
Currently, Mesa throws an linker error in case we dont write to gl_position
and Version is less then 140(GLSL) and 300(GLSL-ES). This patch changes
it so that we don't report an error in case of GLSL-ES.

Similar to the changes to GEN7 command functions, but to GEN6 this time.
As every GPE function has been converted, remove
ilo_cp_assert_no_implicit_flush() calls.
Make these changes
ilo_cp_begin() -> ilo_builder_batch_pointer()
ilo_cp_write() -> direct memory set
ilo_cp_write_bo() -> ilo_builder_batch_reloc()
and use this chance to drop the "_emit_" infix.
Make these changes
ilo_cp_steal_ptr() and memcpy() -> ilo_builder_state_write()
ilo_cp_steal_ptr() -> ilo_builder_state_pointer()
and use this chance to drop the "_emit_" infix.
Make these changes
ilo_cp_steal_ptr() and memcpy() -> ilo_builder_surface_write()
ilo_cp_steal() and ilo_cp_write() -> ilo_builder_surface_write()

Make these changes

"_emit_" infix.
Remove instruction buffer management from ilo_3d and adapt ilo_shader_cache to
upload kernels to ilo_builder. To be able to do that, we also let ilo_builder
manage STATE_BASE_ADDRESS.
Comparing to how we manage batch and instruction buffers, the new builder
- does not flush
- manages both types of buffers
- manages STATE_BASE_ADDRESS
- uploads kernels using unsynchronized mapping
- has its own decoder for the buffers
- provides more helpers
Do not require a toy_compiler so that it can be used in other places, such as
state dumping. Add a bool to control whether the raw instruction words are
shown.
