| ;; When a function is compiled for profiling, gcc will insert |
| ;; a call to __mcount without checking for resources. Hence, |
| ;; we need save all of the argument registers and temp registers, |
| ;; extract the address of <func_name>, and call the _mcount_internal |
| ;; to do the real work. Finally, restore all the argument registers |
| ;; before returning. |
