    • Use TSpan for TType's array sizes · 86d9c93a
      Shahbaz Youssefi authored 
      Until C++20, std::vector doesn't have a constexpr constructor, which
means TType cannot use a `TVector` for `mArraySizes` if an arrayed type
needs to be created constexpr.  This is needed for the upcoming
textureGatherOffsets implementation.

A new TSpan class is introduced, based on std::span (from C++20) that
holds the pointer/size allocated from a TVector without owning it.
Since TVector's allocation are made from a pool, the allocated memory
will live beyond the vector's destruction.  `TType::mArraySizes` is
changed to this type.

This change will allow a new constexpr constructor to be added to TType
that takes a TSpan as array directly, a value which is constexpr
initialized from a static array (instead of TVector).

    • Vulkan:Transform/feedback instanced draw support · c713abfd
      Tobin Ehlis authored 
      These fixes allow dEQP 3.1 KHR-GLES31.core.vertex_attrib_binding.basic-input*
test cases to pass.

This fixes a bug in instanced drawing with transform feedback buffers
where we were overwriting the initial transform feedback output as new
instances were drawn. To fix this, the vertices in each draw are passed
into a uniform value and the output is offset based on the current instance
and the number of vertices in the draw.

It also fixes a validation error where transform feedback descriptor
was sometimes setting a buffer range of 0. This is not allowed, so in
the 0 case we pull the actual buffer size from the bufferHelper object.

    • Vulkan:Update Vulkan Vertex Attribute Offsets · 67d8b63a
      Tobin Ehlis authored 
      This fixes most of the test for
dEQP 3.1 KHR-GLES31.core.vertex_attrib_binding.basic-input*

The bug fixes is that we were not correctly setting the vertex attribute
offset for vertex attribs that were converted into their own buffer.
We kept the attrib offset from the frontend as if the converted attribs
were in the original buffer, but converted vtx attrib buffers in the VK
backend are tightly packed from the start of the buffer so when converting
the actual offset should be 0.

Also, in order to avoid a VK validation error, this change includes a tmp
workaround to make sure transform feedback output buffer range is never 0,
but sets VK_WHOLE_SIZE in that case. A follow-on fix that focuses on
transform feedback fixes will address this validation error more fully.
