Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2908.mcz
==================== Summary ====================
Name: VMMaker.oscog-eem.2908 Author: eem Time: 22 December 2020, 6:11:26.000244 pm UUID: fddf1a4f-c585-45ab-8a74-442230cd3dbd Ancestors: VMMaker.oscog-eem.2907
StackInterpreter: Provide a selective event printing facility for primGetNextEvent:. Add vm parameter 12 (also potentially settable via a command line argument) to provide a mask of event types to print.
Slang: Upgrade the f:printf: transformation to allow specifying stderr as the stream. Upgrade literal array declararions to allow more than one (mangle the target variable name).

!InterpreterPrimitives commentStamp: 'eem 8/24/2018 11:05' prior: 0! InterpreterPrimitives implements most of the VM's core primitives. It is the root of the interpreter hierarchy so as to share the core primitives amongst the varioius interpreters.
Instance Variables argumentCount <Integer> ffiExceptionResponse <Integer> inFFIFlags <Integer> messageSelector <Integer> newMethod <Integer> nextProfileTick <Integer> objectMemory <ObjectMemory> (simulation only) preemptionYields <Boolean> primFailCode <Integer> osErrorCode <Integer> profileMethod <Integer> profileProcess <Integer> profileSemaphore <Integer> secHasEnvironmentAccess <Integer>
argumentCount - the number of arguments of the current message
ffiExceptionResponse - controls system response to exceptions during FFI calls. See primitiveFailForFFIException:at:
inFFIFlags - flags recording currently only whether the system is in an FFI call
messageSelector - the oop of the selector of the current message
newMethod - the oop of the result of looking up the current message
nextProfileTick - the millisecond clock value of the next profile tick (if profiling is in effect)
objectMemory - the memory manager and garbage collector that manages the heap
preemptionYields - a boolean controlling the process primitives. If true (old, incorrect, blue-book semantics) a preempted process is sent to the back of its run-queue. If false, a process preempted by a higher-priority process is put back at the head of its run queue, hence preserving cooperative scheduling within priorities.
primFailCode - primitive success/failure flag, 0 for success, otherwise the reason code for failure
osErrorCode - a 64-bit value settable by external primitives conveying arbitrary error codes from the operating system and/or system libraries
profileMethod - the oop of the method at the time nextProfileTick was reached
profileProcess - the oop of the activeProcess at the time nextProfileTick was reached
profileSemaphore - the oop of the semaphore to signal when nextProfileTick is reached
secHasEnvironmentAccess - the function to call to check if access to the envronment should be granted to primitiveGetenv !
