Differences From Artifact [9c077ad9ee]:

To Artifact [aba6c5c543]:

  • File tests/ForwardingTests.m — part of check-in [0c332aa2d2] at 2013-12-27 02:07:14 on branch trunk — Rework forwarding API and ABI.

    It matches the Apple API and ABI now and the forwarding handler itself
    determines whether it should forward or not.

    This moves handling of +[resolve{Class,Instance}Method:] to the runtime
    and allows adding new kinds of forwarding without changing the runtime.

    Also fixes a potential stack problem in the forwarding for MIPS. (user: js, size: 6357) [annotate] [blame] [check-ins using]
