Hi, during a discussion with upstream (MongoDB) they asked me about default Fedora C/C++ build flags. And I don't remember all Fedora System Wide changes where it was introduced,... so is there some place where it's described? Main upstream question was: """ I don't know what is in those various hardening scripts, so hard to say what they do. I am somewhat interested in whether you think we should be applying these flags for our hardened builds. Do you have some guidance on the runtime costs? -fstack-clash-protection -D_GLIBCXX_ASSERTIONS -fcf-protection I'm also curious about why you are applying -fexceptions and -fasynchronous-unwind-tables. The first seems unnecessary for a C++ project, and the second seems potentially interesting, if you have some context on why it is applied. """ So some link or explanation in this thread (which I can link to upstream) would be really helpful. Thanks, Marek (link to upstream issue - https://jira.mongodb.org/browse/SERVER-35935) _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/WYREDEDXEE57GESAB3TTYDG6S5OIX4ZN/
