10633 | The required alignment for V.4 is 16 bytes, or 8 bytes if -meabi is |
10634 | given. (But note below and in sysv4.h that we require only 8 and | |
10635 | may round up the size of our stack frame anyways. The historical | |
10636 | reason is early versions of powerpc-linux which didn't properly | |
10637 | align the stack at program startup. A happy side-effect is that | |
10638 | -mno-eabi libraries can be used with -meabi programs.) | |
10639 | ||
50d440bc | 10640 | The EABI configuration defaults to the V.4 layout. However, |
5376a30c KR |
10641 | the stack alignment requirements may differ. If -mno-eabi is not |
10642 | given, the required stack alignment is 8 bytes; if -mno-eabi is | |
10643 | given, the required alignment is 16 bytes. (But see V.4 comment | |

12980 | multiple inheritance. The thunk acts as a wrapper around a virtual | |
12981 | function, adjusting the implicit object parameter before handing | |
12982 | control off to the real function. | |
12983 | ||
12984 | First, emit code to add the integer DELTA to the location that | |
12985 | contains the incoming first argument. Assume that this argument | |
12986 | contains a pointer, and is the one used to pass the `this' pointer | |
12987 | in C++. This is the incoming argument *before* the function | |
12988 | prologue, e.g. `%o0' on a sparc. The addition must preserve the | |
12989 | values of all other incoming arguments. | |
17167fd8 MM |
12990 | |
12991 | After the addition, emit code to jump to FUNCTION, which is a | |
a4f6c312 SS |
12992 | `FUNCTION_DECL'. This is a direct pure jump, not a call, and does |
12993 | not touch the return address. Hence returning from FUNCTION will | |
12994 | return to whoever called the current `thunk'. | |
17167fd8 | 12995 | |
a4f6c312 SS |
12996 | The effect must be as if FUNCTION had been called directly with the |
12997 | adjusted first argument. This macro is responsible for emitting | |
12998 | all of the code for a thunk function; output_function_prologue() | |
12999 | and output_function_epilogue() are not invoked. | |
17167fd8 | 13000 | |
a4f6c312 SS |
13001 | The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already |
13002 | been extracted from it.) It might possibly be useful on some | |
13003 | targets, but probably not. | |
17167fd8 | 13004 | |
a4f6c312 SS |
13005 | If you do not define this macro, the target-independent code in the |
13006 | C++ frontend will generate a less efficient heavyweight thunk that | |
13007 | calls FUNCTION instead of jumping to it. The generic approach does | |
13008 | not support varargs. */ | |
