DECL_THUNK_P (in a member FUNCTION_DECL)
Usage of language-independent fields in a language-dependent manner:
- TREE_USED
- This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
-
TYPE_ALIAS_SET
This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
forth as a substitute for the mark bits provided in `lang_type'.
At present, only the six low-order bits are used.
- TYPE_BINFO
+ TYPE_LANG_SLOT_1
For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
BINFO_VIRTUALS
- For a binfo, this is a TREE_LIST. The BV_DELTA of each node
- gives the amount by which to adjust the `this' pointer when
- calling the function. If the method is an overriden version of a
- base class method, then it is assumed that, prior to adjustment,
- the this pointer points to an object of the base class.
+ For a binfo, this is a TREE_LIST. There is an entry for each
+ virtual function declared either in BINFO or its direct and
+ indirect primary bases.
+
+ The BV_DELTA of each node gives the amount by which to adjust the
+ `this' pointer when calling the function. If the method is an
+ overridden version of a base class method, then it is assumed
+ that, prior to adjustment, the this pointer points to an object
+ of the base class.
The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
- index of the vcall offset for this entry. If
- BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
- use a virtual thunk, as opposed to an ordinary thunk.
+ index of the vcall offset for this entry.
The BV_FN is the declaration for the virtual function itself.
to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
to extract the VAR_DECL for the complete vtable.
- DECL_ARGUMENTS
- For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
-
DECL_VINDEX
This field is NULL for a non-virtual function. For a virtual
function, it is eventually set to an INTEGER_CST indicating the
index in the vtable at which this function can be found. When
a virtual function is declared, but before it is known what
- function is overriden, this field is the error_mark_node.
+ function is overridden, this field is the error_mark_node.
Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
the virtual function this one overrides, and whose TREE_CHAIN is
the old DECL_VINDEX. */

A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
The address of the ordinary FUNCTION_DECL is given by the
DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
- FUNCTION_DECL. The job of the thunk is to adjust the `this'
- pointer before transferring control to the FUNCTION_DECL.
+ FUNCTION_DECL. The job of the thunk is to either adjust the this
+ pointer before transferring control to the FUNCTION_DECL, or call
+ FUNCTION_DECL and then adjust the result value. Note, the result
+ pointer adjusting thunk must perform a call to the thunked
+ function, (or be implemented via passing some invisible parameter
+ to the thunked function, which is modified to perform the
+ adjustment just before returning).
A thunk may perform either, or both, of the following operations:
- o Adjust the `this' pointer by a constant offset.
- o Adjust the `this' pointer by looking up a vcall-offset
+ o Adjust the this or result pointer by a constant offset.
+ o Adjust the this or result pointer by looking up a vcall or vbase offset
in the vtable.
- If both operations are performed, then the constant adjument to
- `this' is performed first.
-
- The constant adjustment is given by THUNK_DELTA. If the
- vcall-offset is required, the index into the vtable is given by
- THUNK_VCALL_OFFSET. */
+ A this pointer adjusting thunk converts from a base to a derived
+ class, and hence adds the offsets. A result pointer adjusting thunk
+ converts from a derived class to a base, and hence subtracts the
+ offsets. If both operations are performed, then the constant
+ adjustment is performed first for this pointer adjustment and last
+ for the result pointer adjustment.
+
+ The constant adjustment is given by THUNK_FIXED_OFFSET. If the
+ vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
+ used. For this pointer adjusting thunks, it is the vcall offset
+ into the vtable. For result pointer adjusting thunks it is the
+ binfo of the virtual base to convert to. Use that binfo's vbase
+ offset.
+
+ It is possible to have equivalent covariant thunks. These are
+ distinct virtual covariant thunks whose vbase offsets happen to
+ have the same value. THUNK_ALIAS is used to pick one as the
+ canonical thunk, which will get all the this pointer adjusting
+ thunks attached to it. */
