/**
|
|
* @file min.c
|
|
* @brief Implements the OP_MIN opcode for finding the minimum of two values in the VM.
|
|
*
|
|
* This file handles the OP_MIN instruction, which finds the minimum of two integer values.
|
|
* The values are popped from the stack, and the result is pushed back.
|
|
*
|
|
* Behavior:
|
|
* - Pops two integer values from the stack.
|
|
* - Finds the minimum of the two values.
|
|
* - Pushes the result onto the stack.
|
|
*
|
|
* Error Handling:
|
|
* - Exits with an error if the operands are not integers.
|
|
*
|
|
* Example:
|
|
* // Bytecode: OP_MIN
|
|
* // Stack before: [10, 42]
|
|
* // Stack after: [10]
