[PATCH] D50837: [x86/SLH] Teach SLH to harden against the "ret2spec" attack by implementing the proposed mitigation technique described in the original design document.

[Chandler Carruth via Phabricator via llvm-commits]

chandlerc updated this revision to Diff 160988.
chandlerc added a comment.

Include a minor update to the documentation to make it clear that this
component is now implemented, and only jumptables remain unhandled (but can be
handled with retpolines).
