Ideally, it'll be copy-propped and DCE'd away; this removes a source of

The proposed flag is more tolerant than -Wformat-nonliteral.
Specifically, it tolerates common mesa formatting like:
static const char *shader_template = "really long string %d";
printf(shader_template, uniform_number);

With 8 and 16-bit types and anything where we have to use non-trivial
strides registersto deal with restrictions, we end up with things that
look like partial writes even though we don't care about any values in
the register except those written by that instruction. This is
particularly important when dealing with loops because liveness sees
is_partial_write and the fact that an old version from a previous loop
iteration may be valid at that point and extends all purely partially
written values to the entire loop.
This commit adds a new UNDEF instruction which does nothing (the
generator doesn't emit anything) but which does a fake write to the
register. This informs liveness that we don't care about any values
before that point so it won't consider those registers to be falsely
live. We can safely emit UNDEF instructions for all SSA values that
come in from NIR and nearly all temporaries generated by various stages
of the compiler. In particular, we need to insert UNDEF instructions
when we handle region restrictions because the newly allocated registers
are almost guaranteed to be partially written.
No shader-db changes.

are slightly different (include an OpenCLstd_ prefix), so this patch
also fixes vtn_opencl.c to use those.

If libdrm is found the pipe loader enables drm anyway, and that is
pretty much the only extra dependency this code has.
This enables creating libva display using a drm fd without having
to enable the DRM (GBM really) backend of EGL, which is completely
unrelated.
Leaving the X11 platforms alone as they would still result in the
additional inclusion of extra deps.

This might be slightly faster since we're doing one read rather than
two before we decide to skip. The more important reason, however, is
because no_spill prevents us from re-spilling spill registers. In the
new world in which we don't re-calculate liveness every spill, we may
not have valid liveness for spill registers so we shouldn't even look
their live ranges up.

The automatic header generation unifies identical registers in a series
and only emits definitions for the first one. This is mostly to avoid
emitting excessive definitions for CB registers, but special-casing
an exception for this family of registers doesn't seem worth it.
The definition of the fields differs, but PITCH_GFX9 is a mere extension
of PITCH_GFX6 that does not conflict with any other fields.
This aligns the definitions with what will be generated from the
register JSON.
The information about how large the fields really are is preserved in
the register database.
The field layout wasn't actually changed in gfx9, so having the suffix
isn't very useful. The field *contents* were changed, but this is
reflected in the V_xxx_xxx definitions and is taken into account by
the ac_debug logic based on the register JSON.
This aligns the definitions with what will be generated from the
register JSON.
We will derive both the debugging tables and (the majority of) the
register headers from descriptions in JSON, instead of deriving the
debugging tables from an awkward parsing of the register headers.
Some of the scripts are useful for maintaining the register database
itself. The scripts are designed to output reasonably readable JSON
by default.

Change the iris_binding_table to keep track of what surfaces are
actually going to be used, then assign binding table indices just for
those. Reducing unused bytes on those are valuable because we use a
reduced space for those tables in Iris.
The rest of the driver can go from "group indices" (i.e. UBO #2) to
BTI and vice-versa using helper functions. The value
IRIS_SURFACE_NOT_USED is returned to indicate a certain group index is
not used or a certain BTI is not valid.
The environment variable INTEL_DISABLE_COMPACT_BINDING_TABLE can be
set to skip compacting binding table.

Stop using brw_compiler to lower the final binding table indices for
surface access. This is done by simply not setting the
'prog_data->binding_table.*_start' fields. Then make the driver
perform this lowering.
This is a better place to perfom the binding table assignments, since
the driver has more information and will also later consume those
assignments to upload resources.
This also prepares us for two changes: use ibc without having to
implement binding table logic there; and remove unused entries from
the binding table.
Since the `block` field in brw_ubo_range now refers to the final
binding table index, we need to adjust it before using to index
shs->constbuf.

Previously the loop for assigning registers was bailing out early if
the register had a null source. I think the intention is that in this
case it isn’t necessary to assign a register. However it was also
missing out the part to fix up the types. This can happen if the
instruction is copy propagated to be a move from a constant half-float
input register. In that case it still needs to fix up the types.
