--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC is emitting the mcount call correctly for each function.
Glibc is the library where the mcount is located and enabling of the timer
(SIGPROF) is enabled and it controls the outputting of the gmon.out.
>>From what I can tell if the timer does not happen, then there will be no
gmon.out outputted.
With a slower/older machine (AMD Athlon(tm) II X4 640 Processor), I sometim=
es
get gmon.out and sometimes don't.=
