Avoid undefined behaviour when calculating subgroup ballot masks

The affected tests are shifting the bits of the last component of the
computed ballot masks by 32. However, the SPIR-V specification
establishes that the result of OpShift* is undefined if `Shift` is
greater than *or equal* to the bit width of the components of `Base`.

Affects:

dEQP-VK.subgroups.ballot_other.*

Components: Vulkan

VK-GL-CTS issue: 2083

dEQP README

This repository contains a GPU testing suite called dEQP (drawElements Quality Program). dEQP contains tests for several graphics APIs, including OpenGL ES, EGL, and Vulkan.

Documentation

Up-to-date documentation for the dEQP is available at Android Open Source Project site.

The .qpa logs generated by the conformance tests may contain embedded png images of the results. These can be viewed with the Cherry tool.

Khronos Vulkan Conformance Tests

This repository includes Khronos Vulkan CTS under external/vulkancts directory. For more information see Vulkan CTS README.

Khronos OpenGL / OpenGL ES Conformance Tests

This repository includes Khronos OpenGL / OpenGL ES CTS under external/openglcts directory. For more information see OpenGL / OpenGL ES CTS README.

ANGLE for Android

ANGLE can be built for Android by following the instructions here.

The resulting ANGLE shared object libraries can be linked against and embedded into dEQP.apk with the --angle-path option. This will cause dEQP.apk to use the ANGLE libraries for OpenGL ES calls, rather than the native drivers.

An ABI must be specified and the directory structure containing the ANGLE shared objects must match it so the build system can find the correct *.so files.

Assuming ANGLE shared objects are generated into ~/chromium/src/out/Release/ and dEQP.apk will be generated with --abis arm64-v8a, issue the following commands:

cd ~/chromium/src/out/Release/
mkdir arm64-v8a && cd arm64-v8a
cp ../lib*_angle.so .

The --angle-path ~/chromium/src/out/Release/ option can then be used to link against and embed the ANGLE shared object files. The full command would be:

python scripts/android/build_apk.py --sdk <path to Android SDK> --ndk <path to Android NDK> --abis arm64-v8a --angle-path ~/chromium/src/out/Release/
