CogVM binaries as per VMMaker.oscog-eem.887/r3085 Spur: Change become to flush method caches for becommed classes. Changes are to - add a BecameActiveClassFlag to becomeEffectsFlags - refuse to do an in-place become on active classes. - flush the caches before the post-become scan of the class table so that forwarded classes can be spotted. i.e. if a class index in a method cache is that of a forwarded class then it was becommed and the cache entry can be voided. Fix bug in sweepToFollowForwardersForPigCompact which failed to update and answer lowest forwarder. Fixes numForwarders == 0 assert failures. Fix bug with become and class table not removing classes which become causes them to be unhashed. Fix bogus assert fail in synchronousSignal:. Refactor following code into ensureSemaphoreForwardedThroughContext: and fix the assert there-in. Use rawOverflowSlotsOf: in bytesInObject:. Cogit: Make sure voidImplicitReceiverCacheAt: sets codeModified if IRCs are inline. Make sure freeMethod: clears cmRefersToYoung Fix assert in cogitPostGCAction: that would fire erroneously in Spur become. Fix regression in V3 become youngReferrers management in VMMaker.oscog-eem.882. We /must/ prune young referrers if mapObjectReferencesInMachineCodeForBecome removes a cog method from youngReferrers because it may get added back and youngReferrers cannot contain duplicates. Fix potential bug in Spur become argument validation. Check for immediates needs to come /after/ following forwarders since an object can become-forward to an immediate. Fix cPICHasForwardedClass:; this did /not/ enumerate the classIndices in a Spur Closed PIC. Install the callPrimitiveBytecode in the Interpreter's bytecodeDispatchTable on Spur. Modify callPrimitiveBytecode to not invoke unknownBytecode processing if at the first bytecode of a primitive method. Correct sign comparison of instructionPointer in justActivateNewMethod. Relax the validInstructionPointer:inMethod:framePointer: assert to accept any pc in initialPC to self size range now that callPrimitiveBytecode is more forgiving. Speed up primitiveMarkUnwindMethod & primitiveMarkHandlerMethod in the StackInterpreter by setting them to 0 in the primitive table. -- best,Eliot

With latest windows SpurVm the test 1 to: 50 do:[: i | Browser open] runs without any crash. I have not tested the VM much othervice, but it looks much more stable. Best regards, Karl On Tue, Sep 30, 2014 at 5:21 AM, Eliot Miranda <[hidden email]> wrote:
