+Standard debugger interface
+===========================
+
+The run-time linker exposes a rendezvous structure to allow debuggers
+to interface with it. This structure, r_debug, is defined in link.h.
+If the executable's dynamic section has a DT_DEBUG element, the
+run-time linker sets that element's value to the address where this
+structure can be found.
+
+The r_debug structure contains (amongst others) the following fields:
+
+ struct link_map *r_map:
+ A linked list of loaded objects.
+
+ enum { RT_CONSISTENT, RT_ADD, RT_DELETE } r_state:
+ The current state of the r_map list. RT_CONSISTENT means that r_map
+ is not currently being modified and may safely be inspected. RT_ADD
+ means that an object is being added to r_map, and that the list is
+ not guaranteed to be consistent. Likewise RT_DELETE means that an
+ object is being removed from the list.
+
+ ElfW(Addr) r_brk:
+ The address of a function internal to the run-time linker which is
+ called whenever r_state is changed. The debugger should set a
+ breakpoint at this address if it wants to notice mapping changes.
+
+This protocol is widely supported, but somewhat limited in that it
+has no provision to provide access to multiple namespaces, and that
+the notifications (via r_brk) only refer to changes to r_map--the
+debugger is notified that a new object has been added, for instance,
+but there is no way for the debugger to discover whether any of the
+objects in the link-map have been relocated or not.
+
+
+Probe-based debugger interface
+==============================
+
+Systemtap is a dynamic tracing/instrumenting tool available on Linux.
+Probes that are not fired at run time have close to zero overhead.
+glibc contains a number of probes that debuggers can set breakpoints
+on in order to notice certain events.
+
+All rtld probes have the following arguments:
+
+ arg1: Lmid_t lmid:
+ The link-map ID of the link-map list that the object was loaded
+ into. This will be LM_ID_BASE for the application's main link-map
+ list, or some other value for different namespaces.
+
+ arg2: struct r_debug *r_debug:
+ A pointer to the r_debug structure containing the link-map list
+ that the object was loaded into. This will be the value stored in
+ DT_DEBUG for the application's main link-map list, or some other
+ value for different namespaces.
+
+map_complete and reloc_complete may have the following additional
+argument:
+
+ arg3: struct link_map *new:
+ A pointer which, if not NULL, points to the entry in the specified
+ r_debug structure's link-map list corresponding to the first new
+ object to have been mapped or relocated, with new->l_next pointing
+ to the link-map of the next new object to have been mapped or
+ relocated, and so on. Note that because `new' is an entry in a
+ larger list, new->l_prev (if not NULL) will point to what was the
+ last link-map in the link-map list prior to the new objects being
+ mapped or relocated.
+
+The following probes are available:
+
+ init_start:
+ This is called once, when the linker is about to fill in the main
+ r_debug structure at application startup. init_start always has
+ lmid set to LM_ID_BASE and r_debug set to the value stored in
+ DT_DEBUG. r_debug is not guaranteed to be consistent until
+ init_complete is fired.
+
+ init_complete:
+ This is called once, when the linker has filled in the main
+ r_debug structure at application startup. init_complete always
+ has lmid set to LM_ID_BASE and r_debug set to the value stored
+ in DT_DEBUG. The r_debug structure is consistent and may be
+ inspected, and all objects in the link-map are guaranteed to
+ have been relocated.
+
+ map_start:
+ The linker is about to map new objects into the specified
+ namespace. The namespace's r_debug structure is not guaranteed
+ to be consistent until a corresponding map_complete is fired.
+
+ map_complete:
+ The linker has finished mapping new objects into the specified
+ namespace. The namespace's r_debug structure is consistent and
+ may be inspected, although objects in the namespace's link-map
+ are not guaranteed to have been relocated.
+
+ map_failed:
+ The linker failed while attempting to map new objects into
+ the specified namespace. The namespace's r_debug structure
+ is consistent and may be inspected.
+
+ reloc_start:
+ The linker is about to relocate all unrelocated objects in the
+ specified namespace. The namespace's r_debug structure is not
+ guaranteed to be consistent until a corresponding reloc_complete
+ is fired.
+
+ reloc_complete:
+ The linker has relocated all objects in the specified namespace.
+ The namespace's r_debug structure is consistent and may be
+ inspected, and all objects in the namespace's link-map are
+ guaranteed to have been relocated.
+
+ unmap_start:
+ The linker is about to remove objects from the specified
+ namespace. The namespace's r_debug structure is not guaranteed to
+ be consistent until a corresponding unmap_complete is fired.
+
+ unmap_complete:
+ The linker has finished removing objects into the specified
+ namespace. The namespace's r_debug structure is consistent and
+ may be inspected.
