DFSan changes the ABI of each function in the module. This makes it possible for a function with the native ABI to be called with the instrumented ABI, or vice versa, thus possibly invoking undefined behavior. A simple way of statically detecting instances of this problem is to prepend the prefix "dfs$" to the name of each instrumented-ABI function. This will not catch every such problem; in particular function pointers passed across the instrumented-native barrier cannot be used on the other side. These problems could potentially be caught dynamically.
