Detailed Description

Implements the OP_BNOT opcode bitwise NOT (uint32).

Opcode snippet included by vm.c. Performs a 32-bit unsigned bitwise NOT on a single integer operand from the VM stack.

Stack effects:

• pops: a
• pushes: (uint32_t)(~a)

Notes:

• Operand is interpreted as 32-bit unsigned when of type VAL_INT; non-integer values are treated as 0.
• The result is pushed as VAL_INT with the 32-bit value preserved in the low bits.
