bbudge@chromium.org changed reviewers:
+ bradnelson@chromium.org

[bbudge, 2015-08-27 21:19:44]

Removing myself and adding Brad since he has a better understanding of how the
tests work.

[bbudge, 2015-08-27 21:20:24]

Actually remove myself.

[bbudge, 2015-08-27 21:23:57]

LGTM but it would be nice to leave some indication of how to add them back (e.g.
a commented out line that would do so.) That way, if we need the polyfill
someday (to implement Phase 2 types) it will be easy.

LGTM

[gdeepti1, 2015-09-01 21:48:17]

PTAL. Added --harmony-simd flag to SimdJs.json to fix performance tests.

I think you'll have to upload a separate, new patch to commit this.
