Enum Profile 

pub enum Profile {
    No,
    Early,
    Late,
}

Whether every function calls a profiler on the way in, and where that call goes.

What -pg asks for, with -mfentry and -mno-fentry choosing between the last two. The choice has already been made against the target by the time this is built, which is why there is no answer here for a command line that named neither.

Variants

No

It does not, which is what nearly every command line asks for.

Early

In front of the prologue, which is the hook a tracer can replace while the program runs.

Late

Once the frame is taken, which is the hook that reads the frame pointer.
