==== 7.5.91 sipush ====

Push short 

Format 

sipush 

byte1 

byte2 

Forms 

sipush = 19 (0x13) 

Stack 

... -> ..., value1.word1, value1.word2 

Description 

The immediate unsigned byte1 and byte2 values are assembled into a signed short where the value of the short is (byte1 << 8) | byte2. The intermediate value is then sign-extended to an int, and the resulting value is pushed onto the operand stack. 

Notes 

If a virtual machine does not support the int data type, the sipush instruction will not be available.
