Detailed Description

Implements the OP_BXOR opcode bitwise XOR (uint32).

This file is an opcode snippet included by vm.c. It implements a 32-bit unsigned bitwise XOR of two integer operands from the VM stack.

Stack effects:

• pops: b, a
• pushes: (uint32_t)(a ^ b)

Notes:

• Operands are taken as 32-bit unsigned integers when of type VAL_INT; non-integer values are treated as 0.
• Result is pushed back as VAL_INT, preserving 32-bit value in the low bits of the 64-bit integer storage.
