Subject: [PATCH] IPA: do not release body if still needed
Date: Thu, 1 Dec 2022 10:59:07 +0100 [thread overview]
Message-ID: <a4208860-1af9-6c47-6109-5c2fe4c9d444@suse.cz> (raw)
Hi.
Noticed during building of libbackend.a with the LTO partial linking.
The function release_body is called even if clone_of is a clone
of a another function and thus it shares tree declaration. We should
preserve it in that situation.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
