I put it after in order to make more obvious it is a MD part (alpha is the sole arch which remove such sections). Some investigations: -R .shstrtab was added in 2017 commit e8a1490d19dbdd7d68fc1a5e96fc7c5115e2c42a from: deraadt <dera...@openbsd.org> date: Sun Sep 17 16:33:07 2017 UTC Some further shrinking, but obviously not enough. Something unknown caused bloat about a month ago (and it wasn't purely the ctf additions since those are being stripped). Maybe the compiler generates different code when stronger debugging information is requested? -R .eh_frame was added in 2004 commit ec828d0bd39e2262e00f331f64c0a74a91cf0e0c from: miod <m...@openbsd.org> date: Fri Nov 5 21:22:37 2004 UTC Binutils 2.15 require more aggressive stripping for installation media binaries, if we want to still fit on floppies (binaries carry one extra section now, which we don't need on installation media). ok deraadt@ I would be interested to know the bytes gained by removing these sections. We might removed them on others archs too. Thanks. -- Sebastien Marie
