Subject: [PATCH v4 1/1] Suppress "has no symbols" linker warnings on macOS.
Date: Tue, 28 Apr 2026 15:27:39 -0500
After a recent macOS update, building Postgres produces warnings
that look like this:
ranlib: warning: 'libpgport_shlib.a(pg_cpu_x86.c.o)' has no symbols
ranlib: warning: 'libpgport_shlib.a(pg_popcount_x86.c.o)' has no symbols
To fix, add a dummy symbol to files that may otherwise have none.
