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