40 * NB: It is not possible to provide a compatible interface
41 * here, if the size of an int is different from the size of a
42 * cell, since we don't know how to promote the arguments. We
43 * simply promote arguments treating them as unsigned integers;
44 * thus pointers will be properly promoted and negative signed
45 * integer value will not be properly promoted. This isn't an
46 * issue for LP64 client programs since this code will simply
47 * pass the entire 64-bit arguments through unchanged.
48 *
49 * XXX: This is not fully capable via this interface. Use
50 * p1275_cif_handler directly for all features. Specifically,
51 * there's no catch_result and no result cells available via this
52 * interface. This interface provided for compatibilty with
53 * existing OBP code. Note that we also assume that the
54 * arguments are not to be sign extended. Assuming the code
55 * using these arguments is written correctly, this should be OK.
