| # Note - we do not try any fancy optimizations of the return |
| # sequences here, it is just not worth it. Instead keep things |
| # simple. Restore all the save resgisters, including the link |
| # register and then perform the correct function return instruction. |
| # We also save/restore r3 to ensure stack alignment. |
