We'll get you some comments by the 12th at the latest. We've gotten
the Murphi implementation running.
One quick question for you. For the test cases in the umm.m file, you
apparently rely upon manual editing of the file to generate all the
different test cases. For example for TEST_WR, you note different
results for when variables are aliased and for when the variables are
Do you have any comprehensive list of all the test cases you
generate? We'd like to make sure we consider all of them in our test
Also, have you considered using the C preprocessor to generate the
different test cases?
