95 | /* If a value represents a C++ object, then the `type' field gives the |
96 | object's compile-time type. If the object actually belongs to some | |
97 | class derived from `type', perhaps with other base classes and | |
98 | additional members, then `type' is just a subobject of the real | |
99 | thing, and the full object is probably larger than `type' would | |
100 | suggest. | |
101 | ||
102 | If `type' is a dynamic class (i.e. one with a vtable), then GDB can | |
103 | actually determine the object's run-time type by looking at the | |
104 | run-time type information in the vtable. When this information is | |
105 | available, we may elect to read in the entire object, for several | |
106 | reasons: | |
107 | ||
108 | - When printing the value, the user would probably rather see the | |
109 | full object, not just the limited portion apparent from the | |
110 | compile-time type. | |
111 | ||
112 | - If `type' has virtual base classes, then even printing `type' | |
113 | alone may require reaching outside the `type' portion of the | |
114 | object to wherever the virtual base class has been stored. | |
115 | ||
116 | When we store the entire object, `enclosing_type' is the run-time | |
117 | type -- the complete object -- and `embedded_offset' is the offset | |
118 | of `type' within that larger type, in bytes. The value_contents() | |
119 | macro takes `embedded_offset' into account, so most GDB code | |
120 | continues to see the `type' portion of the value, just as the | |
121 | inferior would. | |
122 | ||
123 | If `type' is a pointer to an object, then `enclosing_type' is a | |
124 | pointer to the object's run-time type, and `pointed_to_offset' is | |
125 | the offset in bytes from the full object to the pointed-to object | |
126 | -- that is, the value `embedded_offset' would have if we followed | |
127 | the pointer and fetched the complete object. (I don't really see | |
128 | the point. Why not just determine the run-time type when you | |
129 | indirect, and avoid the special case? The contents don't matter | |
130 | until you indirect anyway.) | |
131 | ||
132 | If we're not doing anything fancy, `enclosing_type' is equal to | |
133 | `type', and `embedded_offset' is zero, so everything works | |
134 | normally. */ | |
