[jira] [Updated] (SYSTEMML-2050) Prints show in reverse order of
merge of statement blocks
[ https://issues.apache.org/jira/browse/SYSTEMML-2050?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matthias Boehm updated SYSTEMML-2050:
-------------------------------------
Description:
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.
