ineg : negate an integer : index : visitInsn()

Description

Pops an int off the stack, negates it, and pushes the negated integer value back onto the stack. This is the same as multiplying the integer by -1.

Notes

Because of the two's-complement representation used for negative numbers, negating Integer.MIN_VALUE actually produces Integer.MIN_VALUE, not Integer.MAX_VALUE as you might expect.
