/* diagnostics::digraphs provides support for directed graphs.
|
|
|
|
diagnostics::state_graphs provides a way to extend these graphs
|
|
for representing "state graphs" i.e. a representation of the state
|
|
of memory inside a program, for use e.g. by -fanalyzer.
|
|
|
|
Specifically, nodes represent memory regions, and we use property bags
|
|
in these nodes to stash extra properties (e.g. what kind of memory region
|
|
a node is e.g. stack vs heap). */
