-// This file defines CXXSelfAssignmentChecker, which tests all custom defined
-// copy and move assignment operators for the case of self assignment, thus
-// where the parameter refers to the same location where the this pointer
-// points to. The checker itself does not do any checks at all, but it
-// causes the analyzer to check every copy and move assignment operator twice:
-// once for when 'this' aliases with the parameter and once for when it may not.
-// It is the task of the other enabled checkers to find the bugs in these two
-// different cases.
