Hash : 0004ecc2
Message : Write GL info to test artifact in end2end_tests. These will show up as glinfo.json in the "cas outputs" of the shard that runs these tests. We currently have information for Pixel 4, NVIDIA and Intel Win/Linux, and SwiftShader Windows. GLES 1.x extensions are treated separately. Some WebGL/Mac-only/D3D-only extensions show as unsupported anywhere. In order to capture artifacts on Android, we use a render test output parameter. Bug: angleproject:6379 Change-Id: I560b219b5a586cdbb68d272090f38eedc76aba20 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3176780 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Ian Elliott <ianelliott@google.com> Reviewed-by: Tim Van Patten <timvp@google.com> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com>
