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