icf_safe_so_test.cc has
---
// The goal of this program is to verify if identical code folding
// in safe mode correctly folds functions in a shared object. The
// foo_* functions below should not be folded on X86_64.
// For 32-bit X86, the hidden protected and internal symbols can be folded.
// foo_glob and bar_glob should not be folded, because function pointer
// of foo_glob is taken.
int __attribute__ ((visibility ("protected")))
foo_prot()
{
return 1;
}
int __attribute__ ((visibility ("hidden")))
foo_hidden()
{
return 1;
}
int __attribute__ ((visibility ("internal")))
foo_internal()
{
return 1;
}
static int
foo_static()
{
return 1;
}
int foo_glob()
{
return 2;
}
int bar_glob()
{
return 2;
}
int main()
{
int (*p)() = foo_glob;
(void)p;
foo_static();
foo_prot();
foo_hidden();
foo_internal();
return 0;
}

I don't see why foo_hidden, foo_internal and foo_prot can't be folded for
x86-64.
