Experimentation reveals that gcc ignores -mrtd for the implicit arithmetic functions (e.g. __udivdi3), but not for the implicit memcpy() and memset() functions. Mark the implicit arithmetic functions with __attribute__((cdecl)) to compensate for this. (Note: we cannot mark with with __cdecl, because we define __cdecl to incorporate regparm(0) as well.)

* gcc sometimes likes to insert implicit calls to memcpy().
|
|
* Unfortunately, there doesn't seem to be any way to prevent it from
|
|
* doing this, or to force it to use the optimised memcpy() as seen by
|
|
* C code; it insists on inserting a symbol reference to "memcpy". We
|
|
* therefore include wrapper functions just to keep gcc happy.
