[PATCH] D82699: [driver][arm64] Set target CPU to A12 for compiler invocations that target Apple Silicon

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

Testing this out: `--target=arm64-apple-macos` now does the right thing, but `-march arm64` sets the target triple to iOS (and hence doesn't pass the a12 cpu either). That's different from what Xcode clang does. Could you upstream whatever causes that difference too?
