/* 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. */
