  Hash : 6f755b21
  Message : Use angle::Result in front-end. (Part 1) This covers most of the hot paths used in draw calls. Gives in the order of a 5% reduction in draw call overhead. Bug: angleproject:2491 Change-Id: I2d53afb1163eaceed61fb9cd9ce6c1267c85c0fa Reviewed-on: https://chromium-review.googlesource.com/c/1258149 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
