If the object actually belongs to some 99 class derived from `type', perhaps with other base classes and 100 additional members, then `type' is just a subobject of the real 101 thing, and the full object is probably larger than `type' would 102 suggest. 103 104 If `type' is a dynamic class (i.e. one with a vtable), then GDB can 105 actually determine the object's run-time type by looking at the 106 run-time type information in the vtable. When this information is 107 available, we may elect to read in the entire object, for several 108 reasons: 109 110 - When printing the value, the user would probably rather see the 111 full object, not just the limited portion apparent from the 112 compile-time type. 113 114 - If `type' has virtual base classes, then even printing `type' 115 alone may require reaching outside the `type' portion of the 116 object to wherever the virtual base class has been stored. 117 118 When we store the entire object, `enclosing_type' is the run-time 119 type -- the complete object -- and `embedded_offset' is the offset 120 of `type' within that larger type, in bytes. The value_contents() 121 macro takes `embedded_offset' into account, so most GDB code 122 continues to see the `type' portion of the value, just as the 123 inferior would. 124 125 If `type' is a pointer to an object, then `enclosing_type' is a 126 pointer to the object's run-time type, and `pointed_to_offset' is 127 the offset in bytes from the full object to the pointed-to object 128 -- that is, the value `embedded_offset' would have if we followed 129 the pointer and fetched the complete object. (I don't really see 130 the point. Why not just determine the run-time type when you 131 indirect, and avoid the special case? The contents don't matter 132 until you indirect anyway.) 133 134 If we're not doing anything fancy, `enclosing_type' is equal to 135 `type', and `embedded_offset' is zero, so everything works 136 normally. */ 137 138 extern struct type *value_enclosing_type (struct value *); 139 extern struct value *value_change_enclosing_type (struct value *val, 140 struct type *new_type); 141 extern int value_pointed_to_offset (struct value *value); 142 extern void set_value_pointed_to_offset (struct value *value, int val); 143 extern int value_embedded_offset (struct value *value); 144 extern void set_value_embedded_offset (struct value *value, int val); 145 146 /* For lval_computed values, this structure holds functions used to 147 retrieve and set the value (or portions of the value). 148 149 For each function, 'V' is the 'this' pointer: an lval_funcs 150 function F may always assume that the V it receives is an 151 lval_computed value, and has F in the appropriate slot of its 152 lval_funcs structure. */ 153 154 struct lval_funcs 155 { 156 /* Fill in VALUE's contents.
