-/* A C compound statement that outputs the assembler code for a thunk function,
- 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. */
