[PATCH] D110258: [AArch64][Clang] Always add -tune-cpu argument to -cc1 driver

[Dave Green via Phabricator via cfe-commits]

dmgreen added a comment.

My understanding is that -mtune doesn't work sensibly for Arm backends. The tuning features and architecture features are not separated out at the subtarget level.

Is the idea to teach people to start using it? That sounds dangerous without fixing the issues with it first. Or is this to make sure it's set to something?

(Fixing it properly would be a really good thing.)
