sipush : push two-byte signed integer : index : visitIntInsn()

Description

sipush takes a single parameter, <n> (a 16-bit signed integer), sign extends it to a 32-bit int, and pushes the resulting int onto the operand stack.

sipush is typically more efficient than ldc. It also occupies fewer bytes in the class file.

Example

sipush    0x10    ; push the value 0x10 (16)
                  ; onto the operand stack
