--- Comment #1 from Fangrui Song <i at maskray dot me> ---
The idea is that section+offset should be preferred over
far_away_symbol+large_offset because the former is more relevant.
Update: d1bcae833b32f1408485ce69f844dcd7ded093a8 ("ELF: Don't generate unused
section symbols") may reveal more instances. This suggests that even in the
absence of STT_SECTION (they are optional, not useful if no relocation
references them), we should synthesize them from section headers.
