CogVM binaries as per VMMaker.oscog-eem.270/r2697 Fix the become issue where methods that are identical are failing the code test because their penultimate literals are different objects. Add a flag "cmUsesPenultimateLit" to jitted methods, stealing bits from stackCheckOffset (which was way larger than needed). Shrink stackCheckOffset to 12 bits (still an order of magnitude larger than needed) and add an error check on assigning it. Also add a check for max method size (2^16-1 bytes) and refuse to jit a method that generates too much code. When comparing code, use the cmUsesPenultimateLit flag to decide if comparison includes penultimate lit or not. This is mildly insane, but the VM really doesn't know about the penultimate literal and it shouldn't depend on knowing it can be ignored. Note that the CoInterpreter knows about the last literal; it uses this in supersends. With this hack, Pharo's condenseSources works. Fix bug in primitiveClone/cloneContext: that causes the copy to be a word short. Use isPointerNonInt: and isContextNonInt: in a few places. Implement unknownBytecode. Send unknownBytecode to the activeContext on unknown bytecode if the selector is in the specialObjectsArray. Fix page size bug in platforms/Cross/vm/sqHeapMap.c. -- best, Eliot
