757 used to implement C++ virtual function calls with multiple inheritance. The
758 thunk acts as a wrapper around a virtual function, adjusting the implicit
759 object parameter before handing control off to the real function.
760
761 First, emit code to add the integer DELTA to the location that contains the
762 incoming first argument. Assume that this argument contains a pointer, and
763 is the one used to pass the this' pointer in C++. This is the incoming
764 argument *before* the function prologue, e.g. %o0' on a sparc. The
765 addition must preserve the values of all other incoming arguments.
766
767 After the addition, emit code to jump to FUNCTION, which is a
768 FUNCTION_DECL'. This is a direct pure jump, not a call, and does not touch
769 the return address. Hence returning from FUNCTION will return to whoever
770 called the current thunk'.
771
772 The effect must be as if FUNCTION had been called directly with the adjusted
773 first argument. This macro is responsible for emitting all of the code for
774 a thunk function; FUNCTION_PROLOGUE' and FUNCTION_EPILOGUE' are not
775 invoked.
776
777 The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already been
778 extracted from it.) It might possibly be useful on some targets, but
779 probably not.
780
781 If you do not define this macro, the target-independent code in the C++
782 frontend will generate a less efficient heavyweight thunk that calls
783 FUNCTION instead of jumping to it. The generic approach does not support
784 varargs. */
