To Artifact [a6501f118e]:

• File src/forwarding/apple-forwarding-arm64.S — part of check-in [07d8ae8c34] at 2014-01-14 00:56:13 on branch trunk — apple-forwarding-arm64.S: Fix two bugs.

  The offset for the stored x0 was wrong so that comparing the result of
  the call to -[forwardingTargetForSelector:] with self did not work. The
  other bug was that x19 was not restored before jumping to
  of_method_not_found. (user: js, size: 2153) [annotate] [blame] [check-ins using]
