472 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 473 | |
7ddedda4 MM |
474 | TYPE_ALIAS_SET |
475 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
476 | forth as a substitute for the mark bits provided in `lang_type'. | |
477 | At present, only the six low-order bits are used. | |
478 | ||
95b4aca6 | 479 | TYPE_LANG_SLOT_1 |
0fc81d78 NS |
480 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS. |
481 | For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE. | |
1f81b321 NS |
482 | For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE, |
483 | RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO, | |
0aafb128 | 484 | |
9df2c88c | 485 | BINFO_VIRTUALS |
bb5e8a7f MM |
486 | For a binfo, this is a TREE_LIST. There is an entry for each |
487 | virtual function declared either in BINFO or its direct and | |
488 | indirect primary bases. | |
489 | ||
490 | The BV_DELTA of each node gives the amount by which to adjust the | |
491 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 492 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
493 | that, prior to adjustment, the this pointer points to an object |
494 | of the base class. | |
174eceea | 495 | |
5e19c053 | 496 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 497 | index of the vcall offset for this entry. |
c0bbf652 | 498 | |
5e19c053 | 499 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 500 | |
02dea3ff JM |
501 | If BV_LOST_PRIMARY is set, it means that this entry is for a lost |
502 | primary virtual base and can be left null in the vtable. | |
503 | ||
c35cce41 | 504 | BINFO_VTABLE |
3461fba7 | 505 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 506 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 507 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 508 | |
051e6fd7 MM |
509 | DECL_VINDEX |
510 | This field is NULL for a non-virtual function. For a virtual | |
511 | function, it is eventually set to an INTEGER_CST indicating the | |
512 | index in the vtable at which this function can be found. When | |
513 | a virtual function is declared, but before it is known what | |
4639c5c6 | 514 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 515 | |
bb20cc46 | 516 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
517 | the virtual function this one overrides, and whose TREE_CHAIN is |
518 | the old DECL_VINDEX. */ | |

4706 | pointer before transferring control to the FUNCTION_DECL, or call | |
4707 | FUNCTION_DECL and then adjust the result value. Note, the result | |
4708 | pointer adjusting thunk must perform a call to the thunked | |
4709 | function, (or be implemented via passing some invisible parameter | |
4710 | to the thunked function, which is modified to perform the | |
4711 | adjustment just before returning). | |
19114537 | 4712 | |
eb68cb58 MM |
4713 | A thunk may perform either, or both, of the following operations: |
4714 | ||
4977bab6 ZW |
4715 | o Adjust the this or result pointer by a constant offset. |
4716 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
eb68cb58 MM |
4717 | in the vtable. |
4718 | ||
4977bab6 ZW |
4719 | A this pointer adjusting thunk converts from a base to a derived |
4720 | class, and hence adds the offsets. A result pointer adjusting thunk | |
4721 | converts from a derived class to a base, and hence subtracts the | |
4722 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 4723 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 4724 | for the result pointer adjustment. |
eb68cb58 | 4725 | |
4977bab6 | 4726 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
e00853fd NS |
4727 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
4728 | used. For this pointer adjusting thunks, it is the vcall offset | |
4729 | into the vtable. For result pointer adjusting thunks it is the | |
4730 | binfo of the virtual base to convert to. Use that binfo's vbase | |
4731 | offset. | |
4732 | ||
4733 | It is possible to have equivalent covariant thunks. These are | |
4734 | distinct virtual covariant thunks whose vbase offsets happen to | |
4735 | have the same value. THUNK_ALIAS is used to pick one as the | |
4736 | canonical thunk, which will get all the this pointer adjusting | |
4737 | thunks attached to it. */ | |
