  Ok I understand that you can't help me with that rc5des client. But i
downloaded the VIS SDK for usage of VIS
in my own computations and read in the documentaion that  i need  a sun
compiler version 4 or higher ! They
have an inline expansion file in their SDK ( vis.il ) .
I am not sure if i can use that with gcc ( cause i don't have that cc 4.x
) and i never used Assembler on a sun.

It looks like that :

! @(#)vis.il    1.4     97/03/30 SMI

! The interface to the VIS instructions as declared below (and in the VIS
! User's Guide) will not change, but the macro implementation might change

! in the future.

!
! Pure edge handling instructions
!
! int vis_edge8(void */*frs1*/, void */*frs2*/);
!
        .inline vis_edge8,2
        edge8   %o0,%o1,%o0
        .end
!
! int vis_edge8l(void */*frs1*/, void */*frs2*/);
!
        .inline vis_edge8l,2
        edge8l  %o0,%o1,%o0
        .end

.......
And so on .
