Add script for updating llvm 10

Upstream llvm now lives in a mono-repo along with clang, libc, lldb and a whole bunch of other projects (~90k files at time of writing).
SwiftShader only requires the llvm project from this repo, and does not wish to pull in everything else.

This script performs the following:
 * The llvm10-clean branch is fetched and checked out.
 * A sparse checkout of the llvm project is made to a temporary directory.
 * The third_party/llvm-10.0/llvm is replaced with the latest LLVM version.
 * This is committed and pushed.
 * The original branch is checked out again, and a merge from llvm10-clean to
   the original branch is made.

SwiftShader

License Build Status Build status

Introduction

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.

Building

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

Usage

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.

Contributing

See CONTRIBUTING.txt for important contributing requirements.

The canonical repository for SwiftShader is hosted at: https://swiftshader.googlesource.com/SwiftShader

All changes must be reviewed and approved in the Gerrit review tool at: https://swiftshader-review.googlesource.com

Authenticate your account here: https://swiftshader-review.googlesource.com/new-password

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

Testing

SwiftShader's OpenGL ES implementation can be tested using the dEQP test suite.

See docs/dEQP.md for details.

Third-Party Dependencies

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.

Documentation

See docs/Index.md.
