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

3938 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3939 The address of the ordinary FUNCTION_DECL is given by the
3940 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3941 FUNCTION_DECL. The job of the thunk is to either adjust the this
3942 pointer before transferring control to the FUNCTION_DECL, or call
3943 FUNCTION_DECL and then adjust the result value. Note, the result
3944 pointer adjusting thunk must perform a call to the thunked
3945 function, (or be implemented via passing some invisible parameter
3946 to the thunked function, which is modified to perform the
3947 adjustment just before returning).
3949 A thunk may perform either, or both, of the following operations:
3951 o Adjust the this or result pointer by a constant offset.
3952 o Adjust the this or result pointer by looking up a vcall or vbase offset
3955 A this pointer adjusting thunk converts from a base to a derived
3956 class, and hence adds the offsets. A result pointer adjusting thunk
3957 converts from a derived class to a base, and hence subtracts the
3958 offsets. If both operations are performed, then the constant
3959 adjustment is performed first for this pointer adjustment and last
3960 for the result pointer adjustment.
3962 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3963 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3964 used. For this pointer adjusting thunks, it is the vcall offset
3965 into the vtable. For result pointer adjusting thunks it is the
3966 binfo of the virtual base to convert to. Use that binfo's vbase
3969 It is possible to have equivalent covariant thunks. These are
3970 distinct virtual covariant thunks whose vbase offsets happen to
3971 have the same value. THUNK_ALIAS is used to pick one as the
