Yeah. I'm looking at the hotness calculation first.

[LLVMdev] Loss of precision with very large branch weights
In PR 22718, we are looking at issues with long running applications
producing non-representative frequencies. For example, in these two loops:
int g = 0;
__attribute__((noinline)) void bar() {
g++;
}
extern int printf(const char*, ...);
int main()
{
int i, j, k;
for (i = 0; i < 1000000; i++)
bar();
printf ("g = %d\n", g);
g = 0;
for (i = 0; i < 500000; i++)
