Subject [jira] [Created] (FLEX-34984) for-each loops cross-compile incorrectly
Date Fri, 11 Dec 2015 05:10:10 GMT
Andy Dufilie created FLEX-34984:

             Summary: for-each loops cross-compile incorrectly
                 Key: FLEX-34984
                 URL: https://issues.apache.org/jira/browse/FLEX-34984
             Project: Apache Flex
          Issue Type: Bug
          Components: Falcon, FlexJS
    Affects Versions: Apache FlexJS 0.5.0
            Reporter: Andy Dufilie

When you write a for-each loop, the iterable gets re-evaluated on every iteration.

Example code:
	for each (var item:Object in Test.getItems()) {
  for (var foreachiter0 in Test.getItems()) 
  var item = Test.getItems()[foreachiter0];

It should not call Test.getItems() on every loop iteration. Instead, it should generate a
new local variable prior to entering the loop to store the result.

I believe the offending code is reduce_forLoop() in JSGeneratingReducer.java:
