Reining in profile instrumentation
...for massively inlined template classes, and it is the instrumentation of these that is creating the real problem. And we do want to profile our own functions in the source file itself. For instance, a simple accessor function such as:
// From 'header.h'
struct X {
int k;
int getK() const { return k; }
...
};
// In 'source.cpp'
#include "header.h"
...
X anX;
...
int check = anX.getK();
Now the tiny accessor function which is usually trivially eliminated during inlining, is unnecessarily instrumented with the '__cyg_profile_func_enter...

Have you tried compiling with -fprofile-generate? It enables IR-based profiling
instrumentation, which
