32/// \class Address Address.h "lldb/Core/Address.h"
33/// A section + offset based address class.
34///
35/// The Address class allows addresses to be relative to a section that can
36/// move during runtime due to images (executables, shared libraries, bundles,
37/// frameworks) being loaded at different addresses than the addresses found
38/// in the object file that represents them on disk. There are currently two
39/// types of addresses for a section:
40/// \li file addresses
41/// \li load addresses
42///
43/// File addresses represent the virtual addresses that are in the "on disk"
44/// object files. These virtual addresses are converted to be relative to
45/// unique sections scoped to the object file so that when/if the addresses
46/// slide when the images are loaded/unloaded in memory, we can easily track
47/// these changes without having to update every object (compile unit ranges,
48/// line tables, function address ranges, lexical block and inlined subroutine
49/// address ranges, global and static variables) each time an image is loaded
50/// or unloaded.
51///
52/// Load addresses represent the virtual addresses where each section ends up
53/// getting loaded at runtime. Before executing a program, it is common for
54/// all of the load addresses to be unresolved. When a DynamicLoader plug-in
55/// receives notification that shared libraries have been loaded/unloaded, the
56/// load addresses of the main executable and any images (shared libraries)
57/// will be resolved/unresolved. When this happens, breakpoints that are in
58/// one of these sections can be set/cleared.
