CMake: Add DCHECK_ALWAYS_ON flag Enables macros like ASSERT, UNIMPLEMENTED even in release builds.

SwiftShader is a high-performance CPU-based implementation of the 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
On Windows, open the SwiftShader.sln file using Visual Studio Community or compatible version, and build the solution. 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 ./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:
LLVM contains an outdated and diverged copy of the LLVM compiler framework. Until further notice, maintenance fixes can be made directly in the SwiftShader repository.
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.
