            Bug ID: 89701
           Summary: Provide -fcf-protection=branch,return
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bonzini at gnu dot org
  Target Milestone: ---

Right now the only possibility to specify that combination
-fcf-protection=full, but this is not future proof; if other suboptions are
added later, they could be applied to code that does not support them.

Code that wants to be reliable against future extensions to -fcf-protection
needs to specify each desired option manually, as in
"-fcf-protection=branch,return".
