s: optimize for binary size

github-actions · 2026-04-30T00:39:14Z

GNU testsuite comparison:

Skipping an intermittent issue tests/date/date-locale-hour (passes in this run but fails in the 'main' branch)
Skipping an intermittent issue tests/tail/follow-name (passes in this run but fails in the 'main' branch)
Skipping an intermittent issue tests/tail/tail-n0f (passes in this run but fails in the 'main' branch)
Congrats! The gnu test tests/cut/bounded-memory is now passing!
Congrats! The gnu test tests/printf/printf-surprise is now passing!

@oech3 some of these regressions seem pretty bad:

true_consecutive_calls
-99%
199.4 ns
21,985.3 ns

I wonder if we should remove release-small profile?

oech3 · 2026-04-30T00:59:20Z

This is same with Ubuntu's default.
Also this is very useful for test only usage for less build time. We should NOT remove this profile.

oech3 · 2026-04-30T04:28:53Z

Since we benches uu_main only, we cannot bench overhead of caching binary to RAM. So uu_true bench is not reliable at here.

It might be able to use Command.
