ishlStack
Before | After |
value1 | result |
value2 | ... |
... |
Pops two ints off the stack. Shifts value2 left by the amount indicated in the five low bits of value1. The int result is then pushed back onto the stack.
This is the same as computing the expression:
x * 2s
where s is value1 and x is value2.
Example
; This is like the Java code: ; int x; ; x <<= 3; ; iload_1 ; push integer in local variable 1 onto stack iconst_3 ; push the integer 3 onto the stack ishl ; shift left istore_1 ; store the result in local variable 1Bytecode
