Galen Williamson

We introduce a new proof technique for showing the
correctness of 0CFA-like analyses with respect to small-step
semantics.  We illustrate the technique by proving the correctness of
0CFA for the pure lambda-calculus under arbitrary beta-reduction.  This
result was claimed by Palsberg in 1995; unfortunately, his proof was
flawed.  We provide a correct proof of this result, using a simpler
and more general proof method.  We illustrate the extensibility of the
new method by showing the correctness of an analysis for the
Abadi-Cardelli object calculus under small-step semantics.
