/**
|
|
* @file not.c
|
|
* @brief Implements the OP_NOT opcode for logical NOT in the VM.
|
|
*
|
|
* This file handles the OP_NOT instruction, which performs a logical NOT operation
|
|
* on a boolean value. The value is popped from the stack, and the result is pushed back.
|
|
*
|
|
* Behavior:
|
|
* - Pops a boolean value from the stack.
|
|
* - Performs a logical NOT operation.
|
|
* - Pushes the result (1 or 0) onto the stack.
|
|
*
|
|
* Error Handling:
|
|
* - Exits with an error if the operand is not a boolean value.
|
|
*
|
|
* Example:
|
|
* // Bytecode: OP_NOT
|
|
* // Stack before: [0]
|
|
* // Stack after: [1]
|
