__mcount:
;; 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.
