Unsigned int GLSL parsing fixed Unsigned integers in GLSL were being parsed using the regular integer parser, so it was limited to INT_MAX. All values from INT_MAX + 1 to UINT_MAX could not be parsed properly. Also, added constant folding for the 4 bit conversion glsl functions.

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.
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.
Prebuilt binaries can be found at: https://goo.gl/5MOcdb

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LLVM contains an outdated and diverged copy of the LLVM compiler framework.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.
