Hi, I'm still trying to advance with this. Don't know what caused the
ObjectMemory classPools but it seems to be away now, maybe I did some
mistake last time.
The thing is that now I have in ObjectMemory classPools all the original
ones plus 4 new elements, which I think were added with this
Alien-VMMaker-Support override:
ObjectMemory>>#initialize
initialize
#( #ClassAlien #ClassUnsafeAlien #InvokeCallbackSelector
#SelectorAttemptToAssign)
do: [:c |
[ObjectMemory addClassVarName: c] ifError: []].
the thing is that it never assigns them any value, so my theory is that
there's some code missing? Then in Interpreter it happens something quite
similar. Interpreter>>#initialize does this:
...
#(#PrimErrBadArgument #PrimErrBadIndex #PrimErrBadNumArgs
#PrimErrBadReceiver #PrimErrGenericFailure #PrimErrInappropriate
#PrimErrNoCMemory #PrimErrNoMemory #PrimErrNoModification
#PrimErrNotFound #PrimErrTableIndex #PrimErrUnsupported #PrimNoErr )
do: [:c |
[Interpreter addClassVarName: c] ifError: []].
#(#primFailCode)
do: [:i | [Interpreter addInstVarName: i] ifError: []].
...
but then never calls initializePrimitiveErrorCodes, which would set the vars
to a meaningfull value.
In conclusion, the question would be, where is this missing initialization
code?
Hope you can help, thanks!
Javier.
