| 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. |
|---|
| 9 | | |
|---|
| 10 | | Input: result in fp0,fp1 |
|---|
| 11 | | |
|---|
| 12 | | d2 & a0 should be kept unmodified |
|---|
| 13 | | |
|---|
| 14 | | Output: moves the result to the true destination reg or mem |
|---|
| 15 | | |
|---|
| 16 | | Modifies: destination floating point register |
