Missing "with amendments" compared to the other languages. We already implement 
some DRs against c++17.

[PATCH] D36532: Add -std=c++17

2017-08-09 Thread Hans Wennborg via Phabricator via cfe-commits 
hans created this revision.

As suggested on PR33912.

Trying to keep this small to make it easy to merge to the 5.0 branch. We can do 
a follow-up with more thorough renaming (diagnostic text, options, ids, etc.) 
later.

(For c++14 this was done in r215982, and I think a smaller patch for the 3.5 
branch:
