CogVM binaries as per VMMaker.oscog-eem.255/r2672 [New[Co]]ObjectMemory: Fix becomeForward: so that objects whose references are deleted are freed and can no longer be resurrected via allObjects or allInstances. Remove freed young roots from the rootsTable. Filter freed objects pointed to from the extraRootsTable (because these locations can change it is wrong to remove entries from the extraRootsTable). Make primitiveIdentityHash pop all arguments, for Newspeak VMMirrors. StackToRegisterMappingCogit: Fix marshalling of absent receiver sends. The items beneath the arguments (and to-be-pushed receiver) must be spilled before the receiver is pushed. Improve code quality for numArgs > numRegArgs sends when receiver is not a spill and there are no uses of ReceiverResultReg amongst args. e.g. now avoids loading ReceiverResultReg from stack in code such as 1 with: 2 with: 3. -- best, Eliot
