    • Implement VK_EXT_separate_stencil_usage · 009667d5
      Sean Risser authored 
      This extension allows users to query and specify different usages for
the main image and the stencil. SwiftShader does not use an image's
usage for non-debug purposes outside of
vkGetPhysicalDeviceImageFormatProperties2. This applies to separate
stencil usage as well.

Bug: b/176098507
Tests: dEQP-VK.pipeline.sampler.separate_stencil_usage.*
Tests: dEQP-VK.renderpass.suballocation.multisample.separate_stencil_usage.*
Tests: dEQP-VK.renderpass2.suballocation.multisample.separate_stencil_usage.*

    • Add support for Vulkan12Properties · ff29e249
      Sean Risser authored 
      VkPhysicalDeviceVulkan12Properties was added to the core spec by Vulkan
1.2. It allows users to query the following properties simultaneously:
    * VkPhysicalDeviceDriverProperties
    * VkPhysicalDeviceFloatControlsProperties
    * VkPhysicalDeviceDescriptorIndexingProperties
    * VkPhysicalDeviceDepthStencilResolveProperties
    * VkPhysicalDeviceSamplerFilterMinmaxProperties
    * VkPhysicalDeviceTimelineSemaphoreProperties
    * and framebufferIntegerColorSampleCounts

All these structs are a part of the core spec and must be supported.

    • Optimize reciprocal sqrt operation · 1cc5b335
      Antonio Maiorano authored 
      This change deprecates rr::RcpSqrt_pp with rr::RcpSqrt. As with Rcp,
RcpSqrt computes the result using Newton-Rhapson if it's faster and the
initial approximation intrinsic is available on the current target.
Currently, only LLVM on Intel will use NR for RelaxedPrecision. Note
that passing in Precision::Relaxed will produce a faster, but less
precise reciprocal sqrt.

Also made it so that SprivShader instruction GLSLstd450InverseSqrt now
invokes RcpSqrt(x, Precision::Full) instead of performing 1/sqrt(x).
Note that the Vulkan spec states that inversesqrt()'s precision is 2
ULP, and sqrt()'s precision is inherited from 1.0 / inversesqrt();
however, our rr::Sqrt is implemented in terms of x86's sqrt intrinsic on
x86, or as calls to sqrt from Math.h.

    • Optimize reciprocal operation · d1561871
      Antonio Maiorano authored 
      This change deprecates rr::Rcp_pp with rr::Rcp, which makes sure to
correctly compute the reciprocal using the Newton-Rhapson refinement
only if the current target supports the required instrinsic, otherwise
using 1 / x. Currently, only LLVM on Intel will use NR. Note that
passing in Precision::Relaxed will produce a faster, but less precise
reciprocal.

Also removed PixelProgram::linearToSRGB as it's unused.
