Reject copying from GL_RGB10_A2 to unsized formats. glCopyTexImage2D() with an framebuffer format of GL_RGB10_A2 and internalformat of GL_LUMINANCE_ALPHA was hitting the UNIMPLEMENTED() assert. The spec states that: If an effective internal format exists that has * the same component sizes as, * component sizes greater than or equal to, or * component sizes smaller than or equal to those of the source buffer's effective internal format (for all matching components in <internalformat>), that format is chosen for the new image array and this is the effective internal format of the new texel array. There is no unorm luminance+alpha format that has all components either greater or smaller, so this operation is invalid.

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
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

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 performing:
git push origin HEAD:refs/for/master
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LLVM contains an outdated and diverged copy of the LLVM compiler framework.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.
