d8038c8d09 intel/genxml: Ignore tail leading/trailing whitespace in node_validator()
When importing or flattening genxml with the genxml_import.py script
in MR !20593, it can lead to the tail portion of xml items differing
in whitespace.

If we strip the trailing and leading whitespace from the tail string,
and the strings are equivalent, then we can consider the xml items to
be equivalent.

2adb0f31fc gallium,mesa/st: Add PIPE_CONTEXT_NO_LOD_BIAS flag
While desktop GL supports sampler LOD bias, GLES does not. To support the GL use
case, all Gallium drivers are expected to handle sampler LOD bias. However, this
may require shader code to implement (lowering tex to txb, txl to fadd+txl) and
cost resources to push the LOD bias constants into the shader. The issue is
compounded with something like Dolphin's GLES renderer, which does this LOD bias
emulation itself -- meaning that LOD bias is lowered twice when using Dolphin
with GLES! As such, this commit adds a context flag for frontends to communicate
that they will never use sampler LOD bias, allowing the driver to omit the
lowering as a GLES fast path (or, for Dolphin, for performance parity between
GLES and GL).

This will be used on Asahi. It could also be used to optimize a path on
Mali-T720 supported in Panfrost, though I don't intend to write that patch.

54ebddaa0f ail: Force page-alignment for layered attachments
When rendering to a layered depth/stencil attachment, we specify the layer
stride in pages. That means that depth/stencil targets must be page-aligned to
be rendered to correctly.

If we're merely sampling, not rendering, we do not need the extra alignment. So
we add a flag to handle this case so we keep passing the generated ail tests.

Fixes KHR-GLES31.core.texture_cube_map_array.color_depth_attachments

Similarly, we page-align colour attachments. I don't have a good theoretical
justification for this part, but it seems to be necessary and layered rendering
fails otherwise. Possibly the PBE requires page-aligned layers unconditionally?

08e0c5a9cf agx: Fuse compares into selects
This lets us save a LOT of instructions at the cost of increased register
pressure. However, on my shader-db, this is still coming out ahead since no
shaders are hurt for thread count/spills, and only 1/10 of the shaders helped
for instruction count are hurt for register pressure. The shaders most hurt
for pressure have very low pressure (7 -> 15 is the worst case) and you need a
certain number of registers to use a 4 source instruction at all. Analyzing the
hurt shaders, nothing concerns me too much ... this isn't as bad as I feared.

So I think at this point it's worth ripping off the bandage, given the massive
potential for instruction count win. This is a big improvement for some of the
shaders I'm working on for my $SECRET_PROJECT.

e7ffc799d1 agx: Fuse conditions into if's
Simple greedy thing that has the potential to inflate register pressure but
reduces instructions. Thanks to the recent loop work that turns if { break }
into while_icmp, this also implicitly handles fusing conditions into loops,
which is what actually prompted this.

Surprisingly, this helps register pressure on my shader-db (no change to thread
count), I guess by eliminating the boolean temps in case where the sources are
used multiple times.

139e56c0db agx: Only use nest by 1 for loops w/o continue
Apple doesn't do this, but it should be equivalent and it makes it easier to see
that we can use while_icmp for break_if_icmp in loops that don't use continue
(which Apple does do). So, the effect of this commit is to use while_icmp for
most breaks, which saves an instruction.

8f06252e9b agx: Add helper to determine if a NIR loop uses continue
We need to emit extra instructions to handle continues, but if we don't have
any, we can omit those.

5c9495cf37 agx: Omit while_icmp without continue
The only role of the while_icmp at the end of a NIR loop is to make continue
jumps work. If, after emitting the loop, we learn that there are no continues,
there is no need to insert a while_icmp since it would be a no-op anyway.

e71a1469a8 agx: Omit push_exec at top level
In general, loops need a push_exec at the start for correctness. However, a
push_exec at the top level (non-nested) is a no-op, so we can omit and save a
few cycles.
