@jfbastien, What is the minimum Xcode version required to build with this change?

Is that all that was missing? I had to work around `register` and other issues too. Or was that fixed in other patches?

Anyhow, lgtm if bots happy, assuming Linux also works.

Note that there are important steps to take when updating ANGLE. See http://trac.webkit.org/wiki/UpdatingANGLE

The patch is a bit shrunk: Just enabling C++17 for Xcode.
In my local environment, it works fine. But the bot cannot use gnu++17 option...
Can we upgrade the bot's clang?

[Yusuke Suzuki]

Currently I'm using C++14 for ANGLE and libwebrtc. libwebrtc requires a bit change to adopt C++17. The change is posted to the upstream[1].

I think the bot is using clang-4 or so. I'll change xcode option to gnu++1z to make EWS green. Please change this option once build bot is upgraded.

EWS becomes green, let's land it.

[Ryan Haddad]

Though this change is green on EWS and on the webkit.org bots, it causes multiple Apple internal builds to fail. I need to roll this out for now.

Jonathan is going to try to work through some of the build errors that we are seeing so that we can attempt to land this again without any unexpected breakage.

[Ryan Haddad]

Reverted r232052 for reason:

Breaks internal builds.
