This new instruction is the dual of the existing `AliasedDefinition` instruction. Whereas that instruction defines the contents of aliased memory before the function was called, `AliasedUse` represents the potential use of all aliased memory after the function returns. This ensures that writes to aliased memory do not appear "dead", even if there are no further reads from aliased memory within the function itself.
Semmle QL

How do I learn QL and run queries?
There is extensive documentation on getting started with writing QL. You can use the interactive query console on LGTM.com or the QL for Eclipse plugin to try out your queries on any open-source project that's currently being analyzed.
