This calculates if any part of a MIR local could have previously been borrowed. This means that once a local has been borrowed, its bit will be set from that point and onwards, until we see a StorageDead statement for the local, at which points there is no memory associated with the local, so it cannot be borrowed. This is used to compute which locals are live during a yield expression for immovable generators.

A name describing the dataflow analysis that this BitDenotation is supporting. The name should be something suitable for plugging in as part of a filename e.g. avoid space-characters or other things that tend to look bad on a file system, like slashes or periods. It is also better for the name to be reasonably short, again because it will be plugged into a filename. Read more
