From f47f1d91af985a9028fb399da21eab460d887a15 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 21 May 2021 22:35:00 +0200 Subject: nptl: Move pthread_create, thrd_create into libc The symbols were moved using scripts/move-symbol-to-libc.py. The libpthread placeholder symbols need some changes because some symbol versions have gone away completely. But __errno_location@@GLIBC_2.0 still exists, so the GLIBC_2.0 version is still there. The internal __pthread_create symbol now points to the correct function, so the sysdeps/nptl/thrd_create.c override is no longer necessary. There was an issue how the hidden alias of pthread_getattr_default_np was defined, so this commit cleans up that aspects and removes the GLIBC_PRIVATE export altogether.
