This is a newly added flag. We always pass false into it from
nv50_clear_texture, but other callers may want to respect the render
condition. (And the functions were originally spec'd to respect it.)

When NIR was first introduced, Connor added this fake-edge hack to work
around issues related to unreachable blocks. Thanks to GLSL IR's jump
lowering code, the only unreachable code you can have is a block after an
infinite loop. With SPIR-V, we didn't have the jump lowering code so we
could also end up with the "if (...) { break; } else { continue; }" case
which generates an unreachable block after the if. Because of this, most
of NIR had to be fixed up for handling unreachable blocks. The only
remaining case of not handling unreachable blocks was specifically the
block-after-infinite-loop case in dead_cf which was fixed by the previous
commit. We can now delete the fake edge hack.

When an application uses a ton of shaders, we need to evict them
when the code segment is full but this is not really a good solution
if monster shaders are used because code eviction will happen a lot.
To avoid this, it seems better to dynamically resize the code
segment area after each eviction. The maximum size is arbitrary
fixed to 8MB which should be enough.

This fixes a very old issue which happens when the code segment
size is full. A bunch of real applications like Tomb Raider,
F1 2015, Elemental, hit that issue because they use a ton of shaders.
In this case, all shaders are evicted (for freeing space) but all
currently bound shaders also need to be re-uploaded and SP_START_ID
have to be updated accordingly.

If scissor X or Y was set to a negative value then the previous
code might have indicated noop scissors when the scissor range
actually was masking a portion of the framebuffer.
Since fb->_Xmin, _Xmax, _Ymin and _Ymax take scissors into
account, we can use these to test for a noop scissor.

Varying packing would like to mark certain variables as flat.
This works as long as both sides of the interfaces are changed
accordingly. However, with SSO, we disable varying packing on
the outermost stages. We also disable varying packing for
certain tessellation stages.
With SSO, we operate on the producer and consumer separately.
Checks based on the consumer stage and variable are risky, and
can easily lead to altering one half of the interface between
stages, breaking SSO pipeline IO validation.
Just stop monkeying around with interpolation modes unless
required for varying packing. There's no point. This also
disables it in unsafe SSO cases.
Fixes CTS tests:
*.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_MaxPatchVertices_Position_PointSize

A few weeks ago, Jose Fonseca suggested [0] we use .editorconfig files
to try and enforce the formatting of the code, to which Michel Dänzer
suggested [1] we start by importing the existing .dir-locals.el
settings. The first draft was discussed in the RFC [2].
These .editorconfig are a first step, one that has the advantage of
requiring little to no intervention from the devs once the settings
files are in place, but the settings are very limited. This does have
the advantage of applying while the code is being written.
This doesn't replace the need for more comprehensive formatting tools
such as clang-format & clang-tidy, but those reformat the code after
the fact.

Without this, we would pass over the instructions in the SIMD8 program
(which is located earlier in the buffer) when brw_set_uip_jip() is
called to handle the SIMD16 program.
The assertion about compacted control flow was bogus: halt, cont, break
cannot be compacted because they have both JIP and UIP. Instead, we
should never see a compacted instruction in this code at all.

The original motivation was that gen6_clip_state ignored _NEW_POLYGON
as it didn't care about early culling. The only other change was that
Gen6 ignored BRW_NEW_TES_PROG_DATA as it doesn't have tessellation
shaders, but listening to this is harmless as it'll never be signalled.
Now that we've added _NEW_POLYGON for is_drawing_lines/points, we can
merge the two as the distinction is meaningless.
This actually fixes a bug, though: Gen8+ was using the gen6_clip_state
atom because it doesn't care about early culling, but it also needs
BRW_NEW_TES_PROG_DATA, which was missing.

To support WL_bind_wayland_display an authentication function needs to be
provided but this was not being done for this platform as it's not strictly
necessary. However, as this isn't an optional function there's the potential
for a segfault to occur if authentication is mistakenly performed. Protect
against this by providing a function that prints an error.

Up until now, DRI3 was only used for devices that have render nodes, unless
overridden via an environment variable, with it falling back to DRI2 otherwise.
This limitation was there in order to support WL_bind_wayland_display as it
requires client opened device node fds to be authenticated, which isn't possible
when using DRI3. This is an unfortunate compromise as DRI3 provides security
benefits over DRI2.
Instead, allow DRI3 to be used for devices without render nodes but don't
advertise WL_bind_wayland_display in this case. Applications that need this
extension can still be run by disabling DRI3 support via the LIBGL_DRI3_DISABLE
environment variable.

In the fragment shader OutputsWritten is a bitset of FRAG_RESULT_*
enumerants, which represent the location of each color output written
by the shader. The secondary and primary color outputs of a given
render target using dual-source blending have the same location, so
the 'idx' computation below will give the wrong bit as result if the
'var->data.index' term is non-zero -- E.g. if the shader writes the
primary and secondary colors of the FRAG_RESULT_COLOR output,
ir_set_program_inouts will think that the shader writes both
FRAG_RESULT_COLOR and FRAG_RESULT_SAMPLE_MASK, which is just bogus.
That would cause the brw_wm_prog_key::nr_color_regions computation
done in the i965 driver during fragment shader precompilation to be
wrong, which currently leads to unnecessary recompilation of shaders
that use dual-source blending, and triggers an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.

built-in.
gl_SecondaryFragColorEXT should have the same location as gl_FragColor
for the secondary fragment color to be replicated to all fragment
outputs. The incorrect location of gl_SecondaryFragColorEXT would
cause the linker to mark both FRAG_RESULT_COLOR and FRAG_RESULT_DATA0
as being written to, which isn't allowed by the spec and would
ultimately lead to an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.
This should also fix the code below for multiple dual-source-blended
render targets, which no driver currently supports but we have plans
to enable eventually in the i965 driver (the comment saying that no
hardware will ever support it seems rather hilarious).

fragment outputs.
Currently the mesa state tracker relies on there being two bits set
per dual-source output in the gl_program::OutputsWritten bitset, but
that only worked due to a GLSL front-end bug that caused it to set the
OutputsWritten bit for both location and location+1 even though at the
GLSL level the primary and secondary color outputs used for
dual-source blending have the same location. Fix it by extending
outputMapping[] to 2*FRAG_RESULT_MAX elements in order to represent a
mapping from a (location, index) pair to its TGSI output, which should
also make it slightly easier to add support for dual-source blending
in combination with multiple render targets in the long run.
