__mcount:
;; When a function is compiled for profiling, gcc creates code
;; like this at the start of each profiled function:
;;
;; .global <func_name>
;; <func_name>:
;; bsr __mcount
;; <...function's prologue...>
;; <...function's body...>
;;
;; We must save all of the argument registers, extract the
;; address of <func_name>, call _mcount_internal to do the
;; real work and then restore the argument registers before
;; returning.
