[Bf-committers] PVS-Studio Static Analysis

[Jason Wilkins]

If the source line changes then diff isn't a good enough tool.  What
is needed is a that these programs need to maintain a database that
keeps a signature of each problem that is basically an AST of the area
affected and is independent of source line and whitespace changes.
Then you could annotate this database with information about false
positives instead of your source.  Such a database might even be able
to keep new false positives from appearing if you duplicate the
problem exactly in a different source file.
