[PATCH] D153430: [Clang][Driver] Warn on invalid Arm or AArch64 baremetal target triple

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Thank you for implementing this warning. Side note: it would be better to (a) fix the tests separately from (b) implementing the warning and (c) adding tests to demonstrate the warning.
This way the patch is more focused.
