We built such an animal 'bout 6 years ago at Norsk Data, a company that
has long since gone out of the compiler-making business. It was really
quite easy - you could stop the compiler when the abstract tree was
constructed, and shovel the tree into a database (CODASYL that could be
tweaked to have a relational view) along with the file name and other
information. With the report generator it was child's play to sort the
declare and use of functions together, and we found many of these stupid
errors - like TODAY being an integer function and a longint constant...
Sure would be a nice feature to find in a compiler toolbox!
