-!  ======================================================================
-!
-!  Perform the sequence *a = b atomically with respect to previous value
-!  of a (a0). If *a==a0 then assign *a to b, all in one atomic operation.
-!  Returns 1 if assignment happened, and 0 otherwise.	
-!
-!  usage : old_val = compare_and_swap(address, oldval, newval)
-!
-!  -----------------------
-!  Note on REGISTER USAGE:
-!  as this is a LEAF procedure, a new stack frame is not created;
-!  we use the caller stack frame so what would normally be %i (input)
-!  registers are actually %o (output registers).  Also, we must not
-!  overwrite the contents of %l (local) registers as they are not
-!  assumed to be volatile during calls.
-!
-!  So, the registers used are:
-!     %o0  [input]   - the address of the value to increment
-!     %o1  [input]   - the old value to compare with	
-!     %o2  [input]   - the new value to set for [%o0]
-!     %o3  [local]   - work register
