-- compilations as needed to resolve ASIS queries, but if any tree (.adt)
-- files are already present, use those instead. The ASIS-for-GNAT problem
-- appears to be that when doing an OTF compilation something about the
-- generated tree file is not correctly read in, and this shows up when
-- making the Asis.Compilation_Units.Relations.Semantic_Dependence_Order
-- query (and perhaps others). However, if the .adt tree file already exists
-- when the context is opened, then the tree file is properly read in and the
-- Semantic_Dependence_Order query works correctly. So what the following
-- sequence does is initially open the ASIS context, make an ASIS query to
-- force an OTF compilation (which generates and leaves the .adt file), close
-- the context, and then reopens it--though now the adt file exists and is
-- ready to load. And so off we go.
