Currently Go produces shared libraries that cannot be shared between processes because they have relocations against the text segment (not text section). This fixes this by moving some data to sections with magic names recognized by the static linker. Fixes #10914 Updates #9210 Change-Id: I7178daadc0ae87953d5a084aa3d580f4e3b46d47 Reviewed-on: https://go-review.googlesource.com/10300 Run-TryBot: Michael Hudson-Doyle <michael.hudson@canonical.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
