Moved all unused methods to the bottom of the file.
NOT yet ready to DELETE them for 2 reasons:
1) Some code is relevant to Jim's task of finding weakly connected heap groups.
2) If Jim ever decides that a state can have effects that go deeper than just 1 level (i.e. if we have effects that tell us that we can visit a.b.c without changing states), then we'd need to use the code to generate traversal graphs before printing. They've already been modified to (mostly) work with states, but just have a few small bugs from me changing other parts of the code.
stephey [Wed, 23 Mar 2011 10:22:39 +0000 (10:22 +0000)]
Changed a lot of things in RCR. It works for the most part (manually inspected with the state diagram from the power benchmark). There are minor issues with the printout such as empty { } and nothing being inlined since the refCount for states seems to NOT work. Also, there seems to be states with empty effects... which is weird. The major issue is that the buildcode has problems interfacing with the new code. Some problems, not even Jim could figure them out.

Work in progress... I need to rework how to handle the case if we have more than 1 starting location for each state.
Here's a TODO list for things out of my control:
1) Need total number of independent heaproots (for hashtable creation).
2) Need to be able to get connected component ID (heaproot ID) from current state.
3) Need to get to get Demsky's Pointer Analysis Graph (and someone should check the way I used it is correct, see createTraversalGraph and addToTraversalGraphStartingAt)
4) Fix the way BuildCodeOoOJavaCode gets a weakmap on line 1822
5) Need a list a list of Allocs that have transitions leading into them per state (needed to know where to start traversal from a transitioned-to state.)
