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