Fix Version/s: SystemML 1.1
> Prints show in reverse order of merge of statement blocks

> Key: SYSTEMML-2050
> URL: https://issues.apache.org/jira/browse/SYSTEMML-2050
> Project: SystemML
> Issue Type: Bug
> Reporter: Matthias Boehm
> Assignee: Matthias Boehm
> Fix For: SystemML 1.1
>
>
> As pointed out by [~dusenberrymw] - prints currently show up in reverse order
> after the merge of sequences of statement blocks. For instance, the following
> example
> {code}
> print("test1");
> print("test"+2);
> print("test"+3);
> if(1==1){}
> print("test4");
> print("test"+5);
> {code}
> currently produces the following output
> {code}
> test4
> test5
> test1
> test2
> test3
> {code}
> The new instruction scheduling introduced with SYSTEMML-2039 ensures (as a
> byproduct) that prints within one DAG are scheduled in their original order.
> However, after the merge of statement blocks, prints without data
> dependencies can be reordered.
> This task aims to simply sort all DAG output instructions accordingly to
> their line numbers. Note that his only affects the new instruction scheduling
> as used for spark, hybrid_spark, and singlenode.
