--On some targets, it is impossible to use profiling when the frame
--pointer has been omitted.  For example, on x86 GNU/Linux systems,
--the @code{mcount} routine provided by the GNU C Library finds the
--address of the routine that called the routine that called @code{mcount}
--by looking in the immediate caller's stack frame.  If the immediate
--caller has no frame pointer, this lookup will fail.
--
--By default, GCC assumes that the target does allow profiling when the
--frame pointer is omitted.  This macro should be defined to a C
--expression that evaluates to @code{false} if the target does not allow
--profiling when the frame pointer is omitted.
