Understanding the output of -ftime-report

Hi,
I'm trying to understand what each entry in -ftime-report means so that
I can better optimize my C++ code for compilation code.
What I currently have is attached.
What do each of the high entries correspond to (phase generate, parser
struct body, ...), and why could they be so high?
Also which entries are subparts of others? Adding every percentage gives
way more than 100%.
Thanks
