Does the i386 and amd64 built "ld" utility support garbage collection, or is this feature only intended for arm and friends?

OTOH, if you meant LLVM's lld, then yes, that also supports --gc-sections. -Dimitry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAlj5KCQACgkQsF6jCi4glqOTqwCfQyA9PAYf0I48KRt6tCq+8TbH VvIAn376GFS6OekSQ/374cwu4yZ2SR3S =9aIm -----END PGP SIGNATURE-----
