Why not just switch over unconditionally? __fentry__ seems like a better alternative to mcount overall and it has been around long enough that even older deployments should be relatively unaffected.Actually, it is switched on by default for i?86-*-linux* | x86_64-*-linux*. The default for --enable-x86-64-mfentry is "auto", which triggers the mentioned condition. One still has a chance to use "yes" or "no" in addition to "auto" when configuring with --{enable|disable}-x86-64-mfentry.
Oh that's good then. Thanks, Sid
