LukeCheeseman added a comment.
- Introduce the -mbranch-protection option. This is to be used for both pointer authentication and branch protection security features.
- The branch protection compiler support will follow later
- The options available are -mbranch-protection=<type>(+<type>)* where <type> ::= [bti,pac-ret[+leaf,b-key]*]
- This should be the primary way of using branch protection features and the -msign-return-address option should be deprecated
- Remove the b-key selection from the earlier patch for -msign-return-address
