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

3902 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3903 The address of the ordinary FUNCTION_DECL is given by the
3904 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3905 FUNCTION_DECL. The job of the thunk is to either adjust the this
3906 pointer before transferring control to the FUNCTION_DECL, or call
3907 FUNCTION_DECL and then adjust the result value. Note, the result
3908 pointer adjusting thunk must perform a call to the thunked
3909 function, (or be implemented via passing some invisible parameter
3910 to the thunked function, which is modified to perform the
3911 adjustment just before returning).
3913 A thunk may perform either, or both, of the following operations:
3915 o Adjust the this or result pointer by a constant offset.
3916 o Adjust the this or result pointer by looking up a vcall or vbase offset
3919 A this pointer adjusting thunk converts from a base to a derived
3920 class, and hence adds the offsets. A result pointer adjusting thunk
3921 converts from a derived class to a base, and hence subtracts the
3922 offsets. If both operations are performed, then the constant
3923 adjustment is performed first for this pointer adjustment and last
3924 for the result pointer adjustment.
3926 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3927 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3928 used. For this pointer adjusting thunks, it is the vcall offset
3929 into the vtable. For result pointer adjusting thunks it is the
3930 binfo of the virtual base to convert to. Use that binfo's vbase
3933 It is possible to have equivalent covariant thunks. These are
3934 distinct virtual covariant thunks whose vbase offsets happen to
3935 have the same value. THUNK_ALIAS is used to pick one as the
3936 canonical thunk, which will get all the this pointer adjusting
