    • Address cubemap faces as consecutive layers · bb575d48
      Nicolas Capens authored 
      Vulkan cubemaps use six consecutive layers for the faces, so we can
reuse the same addressing logic as for 2D array textures. Hence the
3D lookup vector becomes a 2D coordinate plus layer coordinate after
projection. The only difference is we don't have to clamp to the range
of layers.

This simplifies the sampled image descriptor since we only have to store
a single pointer per mipmap level. We also avoid the per-lane lookup
(gather) operation. YCbCr sampling was adjusted to not use the same
array of buffer pointers.

Also eliminate the unused lodOrBias parameter from computeLod*(). It's
added afterwards.

    • BuiltInPointCoord implementation · 95b1db96
      Alexis Hetu authored 
      BuiltInPointCoord is defined as:

"The following formulas are used to evaluate s and t:

s = 1/2 + (xp - xf) / size
t = 1/2 + (yp - yf) / size

where size is the point’s size; (xp,yp) is the location at which the
point sprite coordinates are evaluated - this may be the framebuffer
coordinates of the fragment center, or the location of a sample; and
(xf,yf) is the exact, unrounded framebuffer coordinate of the vertex
for the point."

So it was implemented by writing (xf,yf) in SetupRoutine, where this
information is present and using the fragment's x and y coordinates
as (xp,yp), which passes the test.

Tests: dEQP-VK.glsl.builtin_var.simple.pointcoord

    • 32 bit compilation fixes for Visual Studio · 5e3c9d53
      Alexis Hetu authored 
      This cl fixes all issues related to building Vulkan using the x86 compiler in Visual Studio:
- Added dummy function to prevent compiler crash in VkGetProcAddress.cpp
- Added missing WIN32 check in SwiftShader's Vulkan unit tests
- Removed alignment code which broke Win32 DLL. Removing all of it should work on all other
  platforms as well.

Minor nit fix:
- Renamed VkWrapper to VkNonDispatchableHandle, which is a more accurate name.
