Will similar changes be needed on the Chromium side when rolling this into
Chromium?  If so, could you commit those changes before committing this?

[mazda, 2014/12/17 17:11:27]

Yes, similar changes like the following are needed on the Chromium.
https://codereview.chromium.org/794573002/diff/20001/components/nacl_nonsfi.gyp

Let me clarify the commit order of the related CLs.

1. The similar change on Chromium side
(https://codereview.chromium.org/794573002/diff/20001/components/nacl_nonsfi.gyp)
2. This CL
3. (After NaCl is rolled), Chrome side change
(https://codereview.chromium.org/794573002/) except the change hunk in 1.

Is my understanding correct?
