Hi Roberto
It seems that I understand.
The whole thing is:
"GC" is trigger on two circumstances. When VM is "paused"(interacting with C), the stack top indicates exactly what it referenced. When VM is "running"(executing instructions), the stack top indicates the last register this function used. So on the latter circumstances, we need to use the instructions to indicate the current top.
Is it right?
