// leaks. Support for annotations is implemented in LeakSanitizer. Annotated
|

// objects will be treated as a source of live pointers, i.e. any heap objects
|

// reachable by following pointers from an annotated object will not be
|
|
// reported as leaks.

|
|
// ANNOTATE_SCOPED_MEMORY_LEAK: all allocations made in the current scope
|

// will be annotated as leaks.
|
|
// ANNOTATE_LEAKING_OBJECT_PTR(X): the heap object referenced by pointer X will
|
|
// be annotated as a leak.
