24fa36ccda Modified the test harness so that it gives a meta tag on failure (in case we want it) 2009-02-10 21:33:53 +00:00

4b44da8008 Removed obsolete conditions from the valid set as we search for constraints 
Previously, conditions from IF branches were being retained even after the end of the whole IF.  Now I use the just-added information from the flow graph as to when those conditions are no longer applicable.

c315352647 Added information in the flow graph edges as to when a condition becomes non-usable (e.g. when the branches of an IF merge again) 2009-02-09 16:57:13 +00:00

d21e7c7437 Changed the usage checker so that it can cope with background knowledge that it does not end up using being unusable 
Previously, if any variable in scope had unusable BK, the usage checker would fail -- even if that variable was not needed in the check (because all BK was processed fully before the later lookup).  So now it is done lazily -- BK is stored with possible errors, which are then ignored unless that BK is looked up and used.

b638c20ee8 Improved an error message from the usage checking 2009-02-08 19:43:09 +00:00

a75a195654 Fixed a bug in the flow utils code that was using the old name stack when removing an element 2009-02-08 19:11:58 +00:00

a71499c268 Filtered out all non-defined names from the background knowledge for each node 
Previously, replicators (and possibly other names) could appear at nodes where they weren't even in scope.

b08ac42547 Augmented the flow graph building to store in each node a list of the names defined at that point 2009-02-08 18:41:30 +00:00

3da315497a Tidied up the flow graph stuff a little by changing the quintuple state into a record type 2009-02-08 18:17:57 +00:00

a29197bcab Fixed the usage checking to handle the new test cases 
This is two changes.  The first drills down through the BK, adding everything relevant (this helps deal with abbreviations of replicators).  The second is that checkPlainVarUsage now only checks non-array variables, and leaves all the array variables to checkArrayUsage, to prevent false alarms where array accesses with an abbreviation of a replicator were being handled by checkPlainVarUsage instead of checkArrayUsage.  The only downside of all the changes is that multidimensional array accesses (they only worked with all constants before) are now no longer handled.
