0.8.1

Deprecated APIs

  • The library semmle.code.cpp.dataflow.DataFlow has been deprecated. Please use semmle.code.cpp.dataflow.new.DataFlow instead.

New Features

  • The DataFlow::StateConfigSig signature module has gained default implementations for isBarrier/2 and isAdditionalFlowStep/4. Hence it is no longer needed to provide none() implementations of these predicates if they are not needed.

Minor Analysis Improvements

  • Data flow configurations can now include a predicate neverSkip(Node node) in order to ensure inclusion of certain nodes in the path explanations. The predicate defaults to the end-points of the additional flow steps provided in the configuration, which means that such steps now always are visible by default in path explanations.
  • The IRGuards library has improved handling of pointer addition and subtraction operations.
