Subject: [PATCH v4 05/37] nptl: Remove longjmp, siglongjmp from libpthread
Date: Fri, 16 Apr 2021 11:20:38 +0200 [thread overview]
Message-ID: <50f98b68745e97127c6df91d4fb1f5a191e8a4c8.1618564630.git.fweimer@redhat.com> (raw)
In-Reply-To: <cover.1618564630.git.fweimer@redhat.com>
The definitions in libc are sufficient, the forwarders are no longer
needed.
The symbols have been moved using scripts/move-symbol-to-libc.py.
s390-linux-gnu and s390x-linux-gnu need a new version placeholder
to keep the GLIBC_2.19 symbol version in libpthread.
Tested on i386-linux-gnu, powerpc64le-linux-gnu, s390x-linux-gnu,
x86_64-linux-gnu. Built with build-many-glibcs.py.
