[PATCH] D38123: [driver] [cl] Add/fix c++17/c++latest

[daxpedda via Phabricator via cfe-commits]

daxpedda created this revision.

Current "/std:c++latest" adds "-std=c++17", VS has it's own "/std:c++17" for that now.

This is my first commit by the way, please tell me if there is anything I can do to improve.
Thanks.
