Subject: [PATCH v2 00/14] libpthread removal: pthread-compat-wrappers and other libc symbols
Date: Fri, 19 Mar 2021 17:29:00 -0300 [thread overview]
Message-ID: <20210319202914.2475530-1-adhemerval.zanella@linaro.org> (raw)
This patchse moves all missing the pthread-compat-wrappers symbols
from libpthread plus some others that are already presented on libc
(the pthread_kill was done to enable the raise removal).
I based this version on top of Florian's 'Transparent multi-version
symbol support' [1] so it can use compat_symbol without the
strong_alias requirement.
It has been tested on i686-linux-gnu and x86_64-linux-gnu, and
built by build-many-glibcs.py for all ABIs that required abilist
changes.
Changes from v1 [2]:
* Make libc version the default one for lseek, open, pread, and pwrite.
* Make aarch64 and nios2 libpthread __send compat symbol.
* Removed alpha specific implementation for pread and pwrite.
* Renamed the commit message for msgrcv, msgsnd, and sigsupend.
* Fixed the split pthread_kill abi addition.
* Fixed the localplt.data for raise on arm.
