35 /* This file defines macros which can be used to annotate intentional memory
36 * leaks. Support for annotations is implemented in HeapChecker and
37 * LeakSanitizer. Annotated objects will be treated as a source of live
38 * pointers, i.e. any heap objects reachable by following pointers from an
39 * annotated object will not be reported as leaks.
40 *
41 * ANNOTATE_SCOPED_MEMORY_LEAK: all allocations made in the current scope
42 * will be annotated as leaks.
43 * ANNOTATE_LEAKING_OBJECT_PTR(X): the heap object referenced by pointer X will
44 * be annotated as a leak.
45 *
46 * Note that HeapChecker will report a fatal error if an object which has been
47 * annotated with ANNOTATE_LEAKING_OBJECT_PTR is later deleted (but
48 * LeakSanitizer won't).
