648 used to implement C++ virtual function calls with multiple inheritance. The
649 thunk acts as a wrapper around a virtual function, adjusting the implicit
650 object parameter before handing control off to the real function.
652 First, emit code to add the integer DELTA to the location that contains the
653 incoming first argument. Assume that this argument contains a pointer, and
654 is the one used to pass the this' pointer in C++. This is the incoming
655 argument *before* the function prologue, e.g. %o0' on a sparc. The
656 addition must preserve the values of all other incoming arguments.
658 After the addition, emit code to jump to FUNCTION, which is a
659 FUNCTION_DECL'. This is a direct pure jump, not a call, and does not touch
660 the return address. Hence returning from FUNCTION will return to whoever
661 called the current thunk'.
663 The effect must be as if FUNCTION had been called directly with the adjusted
664 first argument. This macro is responsible for emitting all of the code for
665 a thunk function; FUNCTION_PROLOGUE' and FUNCTION_EPILOGUE' are not
668 The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already been
669 extracted from it.) It might possibly be useful on some targets, but
672 If you do not define this macro, the target-independent code in the C++
673 frontend will generate a less efficient heavyweight thunk that calls
674 FUNCTION instead of jumping to it. The generic approach does not support
