13937 | /* A C compound statement that outputs the assembler code for a thunk |
13938 | function, used to implement C++ virtual function calls with | |
13939 | multiple inheritance. The thunk acts as a wrapper around a virtual | |
13940 | function, adjusting the implicit object parameter before handing | |
13941 | control off to the real function. | |
13942 | ||
13943 | First, emit code to add the integer DELTA to the location that | |
13944 | contains the incoming first argument. Assume that this argument | |
13945 | contains a pointer, and is the one used to pass the `this' pointer | |
13946 | in C++. This is the incoming argument *before* the function | |
13947 | prologue, e.g. `%o0' on a sparc. The addition must preserve the | |
13948 | values of all other incoming arguments. | |
17167fd8 MM |
13949 | |
13950 | After the addition, emit code to jump to FUNCTION, which is a | |
a4f6c312 SS |
13951 | `FUNCTION_DECL'. This is a direct pure jump, not a call, and does |
13952 | not touch the return address. Hence returning from FUNCTION will | |
13953 | return to whoever called the current `thunk'. | |
17167fd8 | 13954 | |
a4f6c312 SS |
13955 | The effect must be as if FUNCTION had been called directly with the |
13956 | adjusted first argument. This macro is responsible for emitting | |
13957 | all of the code for a thunk function; output_function_prologue() | |
13958 | and output_function_epilogue() are not invoked. | |
17167fd8 | 13959 | |
a4f6c312 SS |
13960 | The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already |
13961 | been extracted from it.) It might possibly be useful on some | |
13962 | targets, but probably not. | |
17167fd8 | 13963 | |
a4f6c312 SS |
13964 | If you do not define this macro, the target-independent code in the |
13965 | C++ frontend will generate a less efficient heavyweight thunk that | |
13966 | calls FUNCTION instead of jumping to it. The generic approach does | |
13967 | not support varargs. */ | |
