source_root() function is deprecated in Meson version 0.56.0 because
it returns the source root of the parent project if called from a
subproject.
Why would anyone need Mesa as a meson subproject?
It would be used as subproject in a project generated by command buffer
"decompiler" for Freedreno.

Consider the loop:
float i = 0.0;
while (true) {
if (i != 0.0)
break;
i = i + 1.0;
}
This loop clearly executes exactly one time.
Some trickery is necessary to handle cases where the initial loop value
is very large and the increment is, by comparison, very small. From the
fenu_once test case,
float i = -604462909807314587353088.0;
while (true) {
if (i != -604462909807314587353088.0)
break;
i = i + 36028797018963968.0;
}
This loop should also execute exactly once, but this is much more
challenging to calculate due to precision issues.
Going towards smaller magnitude (i.e., adding a small positive value to
a large negative value) requires a smaller delta to make a difference
than going towards a larger magnitude. For this reason,
-604462909807314587353088.0 + 36028797018963968.0 !=
-604462909807314587353088.0, but -604462909807314587353088.0 +
-36028797018963968.0 == -604462909807314587353088.0. Math class is
tough.

I discovered this problem because adding an algebraic transformation to
convert some uge and ult to ieq or ine caused a couple loops to stop
unrolling. Consider the loop:
uint i = 0;
while (true) {
if (i >= 1)
break;
i++;
}
This loop clearly executes exactly one time. Note that uge(x, 1) is
equivalent to ine(x, 0). Changing the condition to 'if (i != 0)' will
also execute exactly one time.
In the added test cases, uge_once correctly get an exact loop trip count
of 1. Without the changes to nir_loop_analyze.c, the ine_once case
detects a maximum loop trip count of zero and does not get an exact loop
trip count.
No changes in shader-db or fossil-db.

Back when we had a stupid register allocator we did a lot of tricks to
optimize the register usage. The old version of rc_find_free_temporary
did a full program search each time it was called to find out what
registers and channels are actually used and than used that info to give
us the first free register to use.
Now that we have a proper register allocator both for vertex and
fragment shaders, this is no longer needed. Just scan the program when
called for the first time to find the first unused temporary index and
than increment by one everytime. Regalloc can sort it out later.
No change in shader-db confirms this assumption is sound.

There seems to be a problem with running firefox by using Xwayland that
results in a shared resources being not always tagged as using staging.
As a result one process tries to map the resource that was allocated as
one that uses staging without actually using the staging resource, and
hence the mapped range only accounts for the small region that we have
to allocated because a zero-allocation doesn't work, but the application
mapping the resource assumes that a properly sized range is mapped, and
consequently this results in invalid memory access.
To work around this issue disable creating staging for resources that
are created by using shared binding. It is not clear to me whether this
is the best fix, but it seems to quell the issue.

Now we can display h265-10bit decoded frames formats on Raspberry Pi 4

Implements the support to blit SAND modifier with columns 128-bytes-wide
support for P030 format to P010 with UIF layout. This allows sampling
from H265 10-bit frames exported by the video decoder on the Raspberry
Pi 4 devices.
When a DRM_FORMAT_MOD_BROADCOM_SAND128 is enabled with an imported P030
texture. The sand30 blit converts the Luma and Chroma planes to
a tiled P010 format that can be sampled using gallium YUV lowerings
without the interleaved 128-bytes-wide-columns.
This patch follows a similar approach to SAND8 blit but extracting luma
and chroma components from the DRM_FORMAT_P030 format. P030 is a two
plane YCbCr420 format where 3 10 bit components with 2 padding bits are
packed in 4 bytes.
index 0 = Y plane, [31:0] x:Y2:Y1:Y0 2:10:10:10 little endian
index 1 = Cr:Cb plane, [63:0] x:Cr2:Cb2:Cr1:x:Cb1:Cr0:Cb0
[2:10:10:10:2:10:10:10] little endian
After the sand30_blit is done, the shadow texture is an UIF tiled texture
with an R16_UNORM format for luma and R16G16_UNORM for chroma.
To reduce the number of texture-fetch operations during the blit, we
read pairs of 32-bit dwords. They include 6 10-bit unorm components.
And then we write 4 UNORM16 components from an uvec4 because our render
targets do not support writing to UNORM16 formats.
As sampling will be done using 16bpp (luma) and 32bpp (chroma), the
sand30_blit writes consider the different microtile layouts of UIF
format between 64, 32 and 16 bpp.
v2: Fixes save and recovery of constant buffers (Iago)
