Module FlowSummaryImpl

Modules

Module Private

Provides predicates for compiling flow summaries down to atomic local steps, read steps, and store steps.

Imports

AccessPathSyntax

Module for parsing access paths from MaD models, both the identifying access path used by dynamic languages, and the input/output specifications for summary steps.

Predicates

summaryAllowParameterReturnInSelf	Holds if flow is allowed to pass from parameter `p`, to a return node, and back out to `p`.
summaryArgumentNode	Holds if summary node `arg` is at position `pos` in the call `c`.
summaryCallbackRange	Holds if a call targeting `receiver` should be synthesized inside `c`.
summaryNodeType	Gets the type of synthesized summary node `n`.
summaryOutNode	Holds if summary node `out` contains output of kind `rk` from call `c`.
summaryParameterNode	Holds if summary node `p` is a parameter with position `pos`.
summaryPostUpdateNode	Holds if summary node `post` is a post-update node with pre-update node `pre`.
summaryReturnNode	Holds if summary node `ret` is a return node of kind `rk`.

Modules

External	Provides a means of translating externally (e.g., MaD) defined flow summaries into a `SummarizedCallable`s.
RenderSummarizedCallable	Provides query predicates for rendering the generated data flow graph for a summarized callable.
Steps	Provides a compilation of flow summaries to atomic data-flow steps.
TestOutput	Provides a query predicate for outputting a set of relevant flow summaries.
