Ordered compares are what you have in C. Unordered compares are the result
of negating ordered compares (they return true if either argument is NaN).
That special NaN behavior is completely useless here, and unordered
compares produce horrible code with all stable LLVM versions.
(I think that has been fixed in LLVM git)

From GL 4.4 Core profile:
If both PRIMITIVE_RESTART and PRIMITIVE_RESTART_FIXED_INDEX are
enabled, the index value determined by PRIMITIVE_RESTART_FIXED_INDEX is
used. If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not taking a
type parameter, including all of the *Draw* commands other than *DrawEle-

Rather than building a new one every compile. This should reduce some
of the overhead of compiling shaders.
One consequence of this change is that we lose the MachineInstrs dumps
when dumping the shaders via R600_DEBUG. The LLVM IR and assembly is
still dumped, and if you still want to see the MachineInstr dump, you
can run the dumped LLVM IR through llc.

The "normal" detection (querying clflush size) already made sure it is
non-zero, however another method did not. This lead to crashes if this
value happened to be zero (apparently can happen in virtualized environments
at least).

does not work if the stack isn't aligned. Hence use PIPE_ALIGN_STACK function
decoration to fix the segfault which can happen if stack alignment is only

The headers hadn't been regenerated in a long time and had seen a number
of manual modifications. A few changes:
- remove nvc0_2d entirely, use the nv50 header which has the nvc0
values too
- remove 3ddefs, it's identical to the nv50 file
- move macros out into a separate file
Also the upstream rnndb changed the overall chip naming convention; this
was fixed up manually in the generated files until a better solution is
determined.

The headers hadn't been regenerated in a long time, and there were a few
minor divergences. Among other things, rnndb has changed naming to
G80/etc, for now I've not tackled switching that over and manually
replaced the nvidia codenames back to the chip ids. However no other
modifications of the headergen'd headers was done.

brw_swizzle_to_scs has been showing up in my CPU profiling, which is
rather silly - it's a tiny amount of code. It really should be inlined,
and can easily be implemented with fewer instructions.
The enum translation is as follows:
SWIZZLE_X, SWIZZLE_Y, SWIZZLE_Z, SWIZZLE_W, SWIZZLE_ZERO, SWIZZLE_ONE
0 1 2 3 4 5
4 5 6 7 0 1
SCS_RED, SCS_GREEN, SCS_BLUE, SCS_ALPHA, SCS_ZERO, SCS_ONE
which is simply (swizzle + 4) & 7.
Haswell needs extra textureGather workarounds to remap GREEN to BLUE,
but Broadwell and later do not.
This patch replicates swizzle_to_scs in gen7_wm_surface_state.c and
gen8_surface_state.c, since the Gen8+ code can be simplified to a mere
two instructions. Both copies can be marked static for easy inlining.
v2: Put the commit message in the code as comments (requested by
Jason Ekstrand). Also fix a typo.

Valve games use GL_SRGB8 textures. Instead of supporting that properly,
we fell back to MESA_FORMAT_R8G8B8A8_SRGB (with an alpha channel), which
meant that we had to use texture swizzling to override the alpha to 1.0
when sampling. This meant shader recompiles on Gen < 7.5 platforms.
By supporting MESA_FORMAT_R8G8B8X8_SRGB, the hardware just returns 1.0
for us, so we can just use SWIZZLE_XYZW, and avoid any recompiles. All
generations of hardware have supported the format for sampling and
filtering; we can easily support rendering by using the R8G8B8A8_SRGB
format and writing garbage to the X channel. (We do this already for
the non-SRGB version of this format.)
This removes all remaining shader recompiles in a time demo of "Counter
Strike: Global Offensive" (32 -> 0) on Sandybridge.

The logic in brw_blorp_surface_info::set uses brw_format_for_mesa_format
for source surfaces, and brw->render_target_format[] for destination
surfaces. We should do the same in the sRGB MSAA overrides.
Currently, this isn't a problem, since SRGB MSAA buffers are all RGBA.
The next commit will introduce RGBX SRGB MSAA buffers, at which point
we need to get the RGBX -> RGBA format overrides for rendering right.

ir_to_mesa does this - apparently we just forgot or something.
Without this, we'll guess the wrong texture swizzle (XYZW for color
instead of XXX1 for depth) when doing precompiles.
This cuts 26 shader recompiles in a time demo of "Counter Strike:
Global Offensive" (58 -> 32) on Sandybridge. Haswell still has 0
recompiles.

Gen7.5+ platforms that support the "Shader Channel Select" feature leave
key->tex.swizzles[i] as SWIZZLE_NOOP except when GL_DEPTH_TEXTURE_MODE
is GL_ALPHA (which is really uncommon). So, the precompile should leave
them as SWIZZLE_NOOP (aka SWIZZLE_XYZW) as well.
We didn't notice this because prog->ShadowSamplers is not set correctly.
The next patch will fix that problem.

There are too many state flags to fit in one terminal screen, even with
a very tall terminal. Everything is flagged once, so a value of 1 means
that it hasn't ever happened again, and thus isn't terribly interesting.
