iadd : add two integers : index : visitInsn()

Description

Pops two integers from the operand stack, adds them, and pushes the integer result back onto the stack. On overflow, iadd produces a result whose low order bits are correct, but whose sign bit may be incorrect.

Example

bipush  5       ; push first int
bipush  4       ; push second int
iadd            ; add integers
                ; the top of the stack now
                ; contains the integer 9
