Advanced Stack & Memory Management

These instructions manage the evaluation stack's memory footprint and capacity. They provide fine-grained control over resource allocation, helping to optimize performance and prevent memory fragmentation within the virtual machine.

Opcode	Arguments	Operands (stack)	Description
init_stack	size	-	Initialize the evaluation stack memory capacity at the beginning of VM execution to prevent reallocation
shrink	-	target, length	Reduces the capacity of the stack to fit its current length
truncate	-	target_size	Clear/reset the stack elements efficiently
