From memory: 

  the first 3(?) integer-type arguments in registers do,d1,d2 and/or
the first 2(?) pointer-type arguments in a0 and a1.

  The TC-specific keyword 'cdecl' allows you to disable this, so
you can link to libraries compiled with Alcyon ( or generate functions
with will be called by the AES ! ).

  Integer-type return value are in d0, but pointers are returned in a0.

  I never use floating point, but I know that TC ST has quite different
floating point formats in version 1.00 and 1.10, 1.10 supporting the
IEEE standard.



             I know that You believe You understand what You think I said, but
             I'm not sure You realize that what You heard is not what I meant.
