gold has an option --print-symbol-counts= which prints: // For each archive archive $archive $members $fetched_members // For each object file symbols $object $defined_symbols $used_defined_symbols In most cases, `$defined_symbols = $used_defined_symbols` unless weak symbols are present. Strangely `$used_defined_symbols` includes symbols defined relative to --gc-sections discarded sections. The `symbols` lines do not appear to be useful. `archive` lines are useful: `$fetched_members=0` lines correspond to unused archives. The information can be used to trim dependencies. This patch implements --print-archive-stats= which prints the number of members and the number of fetched members for each archive.
