Import various libgcc functions from syslinux. 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.) 2007-07-30 02:37:42 +01:00			`/*`
