Fix integer overflow in Random::getInt() Random integer generation was having a signed integer overflow when calculating a range between min and max values. When casting an overflowed value to unsigned int the result by most (if not all) implementations would produce expected results due to modulo wraparound. However, this is not guaranteed to happen as signed integer overflow is regarded as undefined behavior. This change casts the min and max values to unsigned int which has defined under- and overflow behavior.

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.
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 scripts/qpa_image_viewer.html
, by opening the file with a web browser and following its instructions, or using the Cherry tool.
This repository includes Khronos Vulkan CTS under external/vulkancts
directory. For more information see Vulkan CTS README.
This repository includes Khronos OpenGL / OpenGL ES CTS under external/openglcts
directory. For more information see OpenGL / OpenGL ES CTS README.
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/
