56e5b8da8e A mega-patch that gets tocktest compiling again 
However, around a quarter of the tests currently fail...

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

b48129d4e5 Fixed some uses of Map.lookup that used the old system of it working with any monad (in GHC 6.10, it's always Maybe) 2008-11-28 11:38:06 +00:00

be6c57ce5b Corrected some of my documentation of flowAlgorithm that has repeatedly confused me ever since I wrote it 2008-11-20 15:39:06 +00:00

2a15f4ef5f Filled in all the gaps such that the CheckTest tests now run (including some debug output, for now) 
One of the tests fails at the moment because the specification node has two entries associated with it in the flowgraph.  One is the scope-in and one is the scope-out.  I think the analysis is currently picking the scope-out node and looking beyond that, where -- surprise, surprise -- the variable is not used again.  So I need some easy way of telling the flow analyses which of the two nodes I want to start from, in this case and other ones where I also add two nodes related to the same point in the AST.

a417708cda Fixed some of the flow graph tests that were broken by the change to Rep 2008-06-04 18:32:16 +00:00

41ff60cb78 Removed the Rep constructor from Structured and instead added a Rep constructor to SpecType 
This way, all replicators are declared like other names, and their scope is considered replicated.  This simplifies the code a little.

Fixes #55

6df110dce4 Wrap QuickCheck tests into HUnit tests. 
This means all the tests now get run as part of one list, and HUnit keeps track
of the number of failures for us. (The reason I was doing this was so that
tocktest will exit non-zero on QuickCheck test failure too.)

As part of this, I've reworked TestMain's main function quite a bit. It'll now
filter QuickCheck tests into response to options too.
