2.1.0

New Features

  • Added a new predicate DataFlow::getARuntimeTarget for getting a function that may be invoked by a Call expression. Unlike Call.getTarget this new predicate may also resolve function pointers.
  • Added the predicate mayBeFromImplicitlyDeclaredFunction() to the Call class to represent calls that may be the return value of an implicitly declared C function.
  • Added the predicate getAnExplicitDeclarationEntry() to the Function class to get a FunctionDeclarationEntry that is not implicit.
  • Added classes RequiresExpr, SimpleRequirementExpr, TypeRequirementExpr, CompoundRequirementExpr, and NestedRequirementExpr to represent C++20 requires expressions and the simple, type, compound, and nested requirements that can occur in requires expressions.

Minor Analysis Improvements

  • The function call target resolution algorithm has been improved to resolve more calls through function pointers. As a result, dataflow queries may have more results.
