bipush : push one-byte signed integer : index : visitIntInsn()

Description

bipush takes a single parameter, <n> (an 8-bit signed integer), sign extends it to a 32-bit int, and pushes the resulting int value onto the operand stack.

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

Example

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