  Hash : 35cd7332
  Message : Refactor test shader style. This change enforces a lot more consistency. We pass const char * to the Compile functions instead of std::string. Also fixes the indentation of C++11 block comments to be more consistent. Bug: angleproject:2995 Change-Id: Id6e5ea94055d8cbd420df4ea2e81b2d96cb5ce78 Reviewed-on: https://chromium-review.googlesource.com/c/1357103 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
