I found that the optimization must be on in order to see the frequency.

Then I think I shouldn't use -fprofile-arcs. The reason why I used
-fprofile-arcs is when I debugged a program without any flags, I saw
the frequency was zero. When I added this flag, I saw frequency with
values.
I checked the frequency after life_analysis and before
combine_instructions. I used
