I would appreciate anyone interested in objects-as-methods on Cog pounding on the latest Cog VMs (http://www.mirandabanda.org/files/Cog/VM/VM.r2313/) as this involved substantial changes to method lookup/inline cacheing machinery and there could easily be bugs. The tests run, but they're insubstantial compared e.g. to a full coverage test. best Eliot On Sat, Sep 25, 2010 at 9:20 PM, < squeak-dev-noreply@lists.squeakfoundation.org> wrote:

OSCogVM: Support object-as-method: Eagerly evaluate the interpreter version of a primitive to ease the object-as-method implementation and to improve interpreter performance. Refuse to enter anything that isn't a CompiledMethod into the method-lookup cache to avoid open PICs having to check for valid compiled methods. Have various places check for isOopCOmpiledMethod: rather than isCompiledMethod: to allow SmallIntegers to be used as methods. Interpreter: Have various places check for isOopCOmpiledMethod: rather than isCompiledMethod: to allow SmallIntegers to be used as methods. Slang: support super sends by expanding them at translation time. This allows CoInterpreter>>addMethodToCache to avoid cacheing non-compiled methods via a super send, avoiding duplicating SrackInterpreter's method.
