675 used to implement C++ virtual function calls with multiple inheritance. The
676 thunk acts as a wrapper around a virtual function, adjusting the implicit
677 object parameter before handing control off to the real function.
678
679 First, emit code to add the integer DELTA to the location that contains the
680 incoming first argument. Assume that this argument contains a pointer, and
681 is the one used to pass the this' pointer in C++. This is the incoming
682 argument *before* the function prologue, e.g. %o0' on a sparc. The
683 addition must preserve the values of all other incoming arguments.
684
685 After the addition, emit code to jump to FUNCTION, which is a
686 FUNCTION_DECL'. This is a direct pure jump, not a call, and does not touch
687 the return address. Hence returning from FUNCTION will return to whoever
688 called the current thunk'.
689
690 The effect must be as if FUNCTION had been called directly with the adjusted
691 first argument. This macro is responsible for emitting all of the code for
692 a thunk function; FUNCTION_PROLOGUE' and FUNCTION_EPILOGUE' are not
693 invoked.
694
695 The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already been
696 extracted from it.) It might possibly be useful on some targets, but
697 probably not.
698
699 If you do not define this macro, the target-independent code in the C++
700 frontend will generate a less efficient heavyweight thunk that calls
701 FUNCTION instead of jumping to it. The generic approach does not support

1375 pack(pop)'. The pack(push,<n>) pragma specifies the maximum
1376 alignment (in bytes) of fields within a structure, in much the
1377 same way as the __aligned__' and __packed__' __attribute__'s
1378 do. A pack value of zero resets the behaviour to the default.
1379 Successive invocations of this pragma cause the previous values to
1380 be stacked, so that invocations of #pragma pack(pop)' will return
1381 to the previous value. */
