//      alpha version
//              - 6 argument registers for alpha
//              - size of allocation for each table entry address = 64 bits
//                (this was necessary with BL3 of the compiler, it may no
//                 longer be the case but this shouldn't hurt, the system
//                 service exception code will load long anyway)

//        The first line of this file was "6 8" which the new gensrv used
//        to set the number of in-register arguments (6) and the size of a
//        register (8).
//
//        Now instead, the ARGTBL_ENTRY macro itself converts i386/Mips 4
//        byte units into Alpha 8 byte units. This way, if an old version
//        of gensrv is used, we still get the proper byte counts for Alpha.

// To add a system service simply add the name of the service to the below
// table. If the system service has in memory arguments, then immediately
// follow the name of the serice with a comma and following that the number
// of bytes of in memory arguments, e.g. CreateObject,40.
