6 Registers a0 and d0 are assumed to be scratch registers,
7 and are not saved by these functions.
8
9 Register d0 is usually used as the return value register.
10 Exception: Motorola C uses a0 for the return value if it's a pointer.
11
12 This is true of most C compilers for the 68000, including:
13 Digital Research / Alcyon, Lattice, Aztec / Manx, Greenhills, Motorola.
