So far, input_reads was a bitmap tracking which vertex input locations
were being used.
In OpenGL, an attribute bigger than a vec4 (like a dvec3 or dvec4)
consumes just one location, any other small attribute. So we mark the
proper bit in inputs_read, and also the same bit in double_inputs_read
if the attribute is a dvec3/dvec4.
But in Vulkan, this is slightly different: a dvec3/dvec4 attribute
consumes two locations, not just one. And hence two bits would be marked
in inputs_read for the same vertex input attribute.
To avoid handling two different situations in NIR, we just choose the
latest one: in OpenGL, when creating NIR from GLSL/IR, any dvec3/dvec4
vertex input attribute is marked with two bits in the inputs_read bitmap
(and also in the double_inputs_read), and following attributes are
adjusted accordingly.
As example, if in our GLSL/IR shader we have three attributes:
layout(location = 0) vec3 attr0;
layout(location = 1) dvec4 attr1;
layout(location = 2) dvec3 attr2;
then in our NIR shader we put attr0 in location 0, attr1 in locations 1
and 2, and attr2 in location 3 and 4.
Checking carefully, basically we are using slots rather than locations
in NIR.
When emitting the vertices, we do a inverse map to know the
corresponding location for each slot.
v2 (Jason):
- use two slots from inputs_read for dvec3/dvec4 NIR from GLSL/IR.
v3 (Jason):
- Fix commit log error.
- Use ladder ifs and fix braces.
- elements_double is divisible by 2, don't need DIV_ROUND_UP().
- Use if ladder instead of a switch.
- Add comment about hardware restriction in 64bit vertex attributes.

We use *64*_PASSTHRU formats to upload vertex attributes of 64 bits
to avoid conversions. From the BDW PRM, Volume 2d, page 586
(VERTEX_ELEMENT_STATE):
"When SourceElementFormat is set to one of the *64*_PASSTHRU
formats, 64-bit components are stored in the URB without any
conversion. In this case, vertex elements must be written as 128
or 256 bits, with VFCOMP_STORE_0 being used to pad the output
as required. E.g., if R64_PASSTHRU is used to copy a 64-bit Red
component into the URB, Component 1 must be specified as
VFCOMP_STORE_0 (with Components 2,3 set to VFCOMP_NOSTORE)
in order to output a 128-bit vertex element, or Components 1-3 must
be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
element. Likewise, use of R64G64B64_PASSTHRU requires Component 3
to be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
element."
v2,v3 (Jason):
- Don't delete unused formats.

When an application attempts to create many pipelines in a single

creation (for example, due to out of memory errors), the

This moves the nir_lower_indirect_derefs() call into

We want to do this pass in nir to be able to move loop unrolling

There is a increase of 1-3 instructions in a small number of shaders,
and 2 Kerbal Space program shaders that increase by 32 instructions.
The changes seem to be caused be the difference in the GLSL IR vs
NIR variable index lowering passes. The GLSL IR pass creates a
simple if ladder for arrays of size 4 or less, while the NIR pass
implements a binary search for all arrays regardless of size.

This fixes a regression in a bunch of image store vulkan CTS tests
from commit ad38ba1134, which started
using OWORD block read messages to implement UBO loads. The reason
for the failure is that we were giving bogus buffer alignment limits
to the application (1B), so the CTS would happily come back with
descriptor sets pointing at not even word-aligned uniform buffer
addresses.
Surprisingly the sampler messages used to fetch pull constants before
that commit were able to cope with the non-texel aligned addresses,
but the dataport messages used to fetch pull constants after that
commit and the ones used to access storage buffers (before and after
the same commit) aren't as permissive with unaligned addresses.

We rename do_blorp_blit() to try_blorp_blit(), and add a return error
if the surface size for the blit is too large. Now, do_blorp_blit() is
rewritten to try to split the blit into smaller operations if
try_blorp_blit() fails.
Note: In this commit, try_blorp_blit() will always attempt to blit and
never return an error, which matches the previous behavior. We will
enable the size checking and splitting in a future commit.
The motivation for this splitting is that in some cases when we
flatten an image, it's dimensions grow, and this can then exceed the
programmable hardware limits. An example is w-tiled+MSAA blits.
