80 | /* If a value represents a C++ object, then the `type' field gives |
81 | the object's compile-time type. If the object actually belongs | |
82 | to some class derived from `type', perhaps with other base | |
83 | classes and additional members, then `type' is just a subobject | |
84 | of the real thing, and the full object is probably larger than | |
85 | `type' would suggest. | |
86 | ||
87 | If `type' is a dynamic class (i.e. one with a vtable), then GDB | |
88 | can actually determine the object's run-time type by looking at | |
89 | the run-time type information in the vtable. When this | |
90 | information is available, we may elect to read in the entire | |
91 | object, for several reasons: | |
92 | ||
93 | - When printing the value, the user would probably rather see | |
94 | the full object, not just the limited portion apparent from | |
95 | the compile-time type. | |
96 | ||
97 | - If `type' has virtual base classes, then even printing | |
98 | `type' alone may require reaching outside the `type' | |
99 | portion of the object to wherever the virtual base class | |
100 | has been stored. | |
101 | ||
102 | When we store the entire object, `enclosing_type' is the | |
103 | run-time type --- the complete object --- and `embedded_offset' | |
104 | is the offset of `type' within that larger type, in bytes. The | |
105 | VALUE_CONTENTS macro takes `embedded_offset' into account, so | |
106 | most GDB code continues to see the `type' portion of the value, | |
107 | just as the inferior would. | |
108 | ||
109 | If `type' is a pointer to an object, then `enclosing_type' is a | |
110 | pointer to the object's run-time type, and `pointed_to_offset' | |
111 | is the offset in bytes from the full object to the pointed-to | |
112 | object --- that is, the value `embedded_offset' would have if | |
113 | we followed the pointer and fetched the complete object. (I | |
114 | don't really see the point. Why not just determine the | |
115 | run-time type when you indirect, and avoid the special case? | |
116 | The contents don't matter until you indirect anyway.) | |
117 | ||
118 | If we're not doing anything fancy, `enclosing_type' is equal to | |
119 | `type', and `embedded_offset' is zero, so everything works | |
120 | normally. */ | |
