2 |       sto_res.sa 3.1 12/10/90
4 |       Takes the result and puts it in where the user expects it.
5 |       Library functions return result in fp0. If fp0 is not the
6 |       users destination register then fp0 is moved to the
7 |       correct floating-point destination register.  fp0 and fp1
8 |       are then restored to the original contents.
10 |       Input:  result in fp0,fp1
12 |               d2 & a0 should be kept unmodified
14 |       Output: moves the result to the true destination reg or mem
16 |       Modifies: destination floating point register
