Subject: [PATCH 00/14] Move libdl into libc
Date: Wed, 19 May 2021 20:03:34 +0200 [thread overview]
Message-ID: <cover.1621446837.git.fweimer@redhat.com> (raw)
This patch series removes all code from libdl.so.2. I have not removed
the shared object itself because I want to mirror what we are doing for
libpthread, and the discussion there is still ongoing.
There is an oddity because for several targets, the baseline ABI version
for libdl is GLIBC_2.0 and not GLIBC_2.2. This cannot be expressed with
the existing Versions framework. Since the affected targets are more or
less on the way out anyway (hppa, ia64, sh, sparc64), I didn't
overdesign the solution and emitted the required version nodes directly
in scripts/versions.awk.
This move also happens on Hurd because the implementation isn't
separate.
This fixes a POSIX conformance issue with the c99 command because POSIX
requires that dlopen etc. are available without -ldl.
Tested on i386-linux-gnu and x86_64-linux-gnu. Built with
build-many-glibcs.py (including most intermediate steps).
Thanks,
Florian
