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

3941 The address of the ordinary FUNCTION_DECL is given by the
3942 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3943 FUNCTION_DECL. The job of the thunk is to either adjust the this
3944 pointer before transferring control to the FUNCTION_DECL, or call
3945 FUNCTION_DECL and then adjust the result value. Note, the result
3946 pointer adjusting thunk must perform a call to the thunked
3947 function, (or be implemented via passing some invisible parameter
3948 to the thunked function, which is modified to perform the
3949 adjustment just before returning).
3951 A thunk may perform either, or both, of the following operations:
3953 o Adjust the this or result pointer by a constant offset.
3954 o Adjust the this or result pointer by looking up a vcall or vbase offset
3957 A this pointer adjusting thunk converts from a base to a derived
3958 class, and hence adds the offsets. A result pointer adjusting thunk
3959 converts from a derived class to a base, and hence subtracts the
3960 offsets. If both operations are performed, then the constant
3961 adjustment is performed first for this pointer adjustment and last
3962 for the result pointer adjustment.
3964 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3965 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3966 used. For this pointer adjusting thunks, it is the vcall offset
3967 into the vtable. For result pointer adjusting thunks it is the
3968 binfo of the virtual base to convert to. Use that binfo's vbase
3971 It is possible to have equivalent covariant thunks. These are
3972 distinct virtual covariant thunks whose vbase offsets happen to
3973 have the same value. THUNK_ALIAS is used to pick one as the
