List of stackUsage() Examples

Examples of stackUsage()

alt.jiapi.reflect.Instruction.stackUsage()
Get the stack usage this Instruction uses. Negative stack usage means this Instruction consumes(pops) data from stack. Positive stack usage means this Instructions produces(pushes) data on stack.
Some instructions may both consume and produce data on stack. This method returns the total usage after instruction has been executed. @return Stack usage

Examples of alt.jiapi.reflect.Instruction.stackUsage()

        Instruction start = end;


        int stackConsumption = end.stackConsumption();
        while(stackConsumption > 0) {
            start = il.get(idx - 1); // Previous instruction
            stackConsumption -= start.stackUsage();
            idx--;
        }


        return new HotSpot(il, start, end);
    }
