Regres: Generate coverage data on nightly runs Push this to https://github.com/swiftshader-regres/swiftshader-coverage so that it can be viewed at: https://swiftshader-regres.github.io/swiftshader-coverage/ There's quite a lot of new code and fixes in this change. The most notable: * The regres daily run for the subzero backend now produces combined coverage information for all the test runs. The LLVM backend does not produce coverage information. * Regres now takes two additional command line arguments: `gh-user` and `gh-pass` for the swiftshader-regres account. If you omit these, then coverage will not be produced. * test.srcDir has been renamed to checkoutDir, as this was confusing with the `src` directory in the repo. * The coverage JSON now contains a root field to describe the git revision to which it relates. This prevents the coverage going out of sync with the source. * `git.CheckoutRemoteBranch()` drops back to a depth of 1 again. This was only increased to 99 to deal with issues checking out from gitlab, which we don't do any more. * Regres now builds using `third_party/llvm-10.0` * Fixed the `--limit` regres command line flag which wasn't actually limiting, as it was using the len() on the number of groups, not the number of tests.

SwiftShader is a high-performance CPU-based implementation of the Vulkan, OpenGL ES, and Direct3D 9 graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
SwiftShader libraries can be built for Windows, Linux, and Mac OS X.
Android and Chrome (OS) build environments are also supported.
Visual Studio
For building the Vulkan ICD library, use Visual Studio 2019 to open the project folder and wait for it to run CMake. Open the CMake Targets View in the Solution Explorer and select the vk_swiftshader project to build it.
There is also a legacy SwiftShader.sln file for Visual Studio 2017 for building OpenGL ES and Direct3D libraries. Output DLLs will be placed in the out subfolder. Sample executables such as OGLES3ColourGrading can be found under the Tests solution folder and can be run from the IDE.
CMake
Install CMake for Linux, Mac OS X, or Windows and use either the IDE or run the following terminal commands:
cd build cmake .. make --jobs=8 ./gles-unittests ./OGLES2HelloAPI
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.

All changes require a Change-ID tag in the commit message. A commit hook may be used to add this tag automatically, and can be found at: https://gerrit-review.googlesource.com/tools/hooks/commit-msg. To clone the repository and install the commit hook in one go:
git clone https://swiftshader.googlesource.com/SwiftShader && (cd SwiftShader && curl -Lo `git rev-parse --git-dir`/hooks/commit-msg https://gerrit-review.googlesource.com/tools/hooks/commit-msg ; chmod +x `git rev-parse --git-dir`/hooks/commit-msg)
Changes are uploaded to Gerrit by executing:
git push origin HEAD:refs/for/master
SwiftShader's OpenGL ES implementation can be tested using the dEQP test suite.
See docs/dEQP.md for details.
The third_party directory contains projects which originated outside of SwiftShader:
subzero contains a fork of the Subzero project. It is part of Google Chrome‘s (Portable) Native Client project. Its authoritative source is at https://chromium.googlesource.com/native_client/pnacl-subzero/. The fork was made using git-subtree to include all of Subzero’s history, and until further notice it should not diverge from the upstream project. Contributions must be tested using the README instructions, reviewed at https://chromium-review.googlesource.com, and then pulled into the SwiftShader repository.
llvm-subzero contains a minimized set of LLVM dependencies of the Subzero project.
PowerVR_SDK contains a subset of the PowerVR Graphics Native SDK for running several sample applications.
googletest contains the Google Test project, as a Git submodule. It is used for running unit tests for Chromium, and Reactor unit tests. Run git submodule update --init to obtain/update the code. Any contributions should be made upstream.
