682 | used to implement C++ virtual function calls with multiple inheritance. The | |
683 | thunk acts as a wrapper around a virtual function, adjusting the implicit | |
684 | object parameter before handing control off to the real function. | |
685 | ||
686 | First, emit code to add the integer DELTA to the location that contains the | |
687 | incoming first argument. Assume that this argument contains a pointer, and | |
688 | is the one used to pass the this' pointer in C++. This is the incoming | |
689 | argument *before* the function prologue, e.g. %o0' on a sparc. The | |
690 | addition must preserve the values of all other incoming arguments. | |
691 | ||
692 | After the addition, emit code to jump to FUNCTION, which is a | |
693 | FUNCTION_DECL'. This is a direct pure jump, not a call, and does not touch | |
694 | the return address. Hence returning from FUNCTION will return to whoever | |
695 | called the current thunk'. | |
696 | ||
2bfcf297 DB |
697 | The effect must be as if FUNCTION had been called directly with the adjusted |
698 | first argument. This macro is responsible for emitting all of the code for | |
699 | a thunk function; FUNCTION_PROLOGUE' and FUNCTION_EPILOGUE' are not | |
9ebbca7d GK |
700 | invoked. |
701 | ||
702 | The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already been | |
703 | extracted from it.) It might possibly be useful on some targets, but | |
704 | probably not. | |
705 | ||
706 | If you do not define this macro, the target-independent code in the C++ | |
707 | frontend will generate a less efficient heavyweight thunk that calls | |
708 | FUNCTION instead of jumping to it. The generic approach does not support | |
