149 Usage of language-independent fields in a language-dependent manner:
152 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
153 forth as a substitute for the mark bits provided in `lang_type'.
154 At present, only the six low-order bits are used.
157 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
158 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
161 For a binfo, this is a TREE_LIST. There is an entry for each
162 virtual function declared either in BINFO or its direct and
163 indirect primary bases.
165 The BV_DELTA of each node gives the amount by which to adjust the
166 `this' pointer when calling the function. If the method is an
167 overridden version of a base class method, then it is assumed
168 that, prior to adjustment, the this pointer points to an object
171 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
172 index of the vcall offset for this entry.
174 The BV_FN is the declaration for the virtual function itself.
176 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
177 primary virtual base and can be left null in the vtable.
180 This is an expression with POINTER_TYPE that gives the value
181 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
182 to extract the VAR_DECL for the complete vtable.
185 This field is NULL for a non-virtual function. For a virtual
186 function, it is eventually set to an INTEGER_CST indicating the
187 index in the vtable at which this function can be found. When
188 a virtual function is declared, but before it is known what
189 function is overridden, this field is the error_mark_node.
191 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
192 the virtual function this one overrides, and whose TREE_CHAIN is
193 the old DECL_VINDEX. */

3809 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3810 The address of the ordinary FUNCTION_DECL is given by the
3811 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3812 FUNCTION_DECL. The job of the thunk is to either adjust the this
3813 pointer before transferring control to the FUNCTION_DECL, or call
3814 FUNCTION_DECL and then adjust the result value. Note, the result
3815 pointer adjusting thunk must perform a call to the thunked
3816 function, (or be implemented via passing some invisible parameter
3817 to the thunked function, which is modified to perform the
3818 adjustment just before returning).
3820 A thunk may perform either, or both, of the following operations:
3822 o Adjust the this or result pointer by a constant offset.
3823 o Adjust the this or result pointer by looking up a vcall or vbase offset
3826 A this pointer adjusting thunk converts from a base to a derived
3827 class, and hence adds the offsets. A result pointer adjusting thunk
3828 converts from a derived class to a base, and hence subtracts the
3829 offsets. If both operations are performed, then the constant
3830 adjustment is performed first for this pointer adjustment and last
3831 for the result pointer adjustment.
3833 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3834 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3835 used. For this pointer adjusting thunks, it is the vcall offset
3836 into the vtable. For result pointer adjusting thunks it is the
3837 binfo of the virtual base to convert to. Use that binfo's vbase
3840 It is possible to have equivalent covariant thunks. These are
3841 distinct virtual covariant thunks whose vbase offsets happen to
3842 have the same value. THUNK_ALIAS is used to pick one as the
3843 canonical thunk, which will get all the this pointer adjusting
