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