nptl: Remove remaining code from libpthread Only the placeholder compatibility symbols are left now. The __errno_location symbol was removed (moved) using scripts/move-symbol-to-libc.py. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

GLIBC_2.0 __libpthread_version_placeholder F
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.

GLIBC_2.1 __libpthread_version_placeholder F
nptl: Move sem_unlink into libc The symbol was moved using scripts/move-symbol-to-libc.py. A small adjust to the sem_unlink implementation is necessary to avoid a check-localplt failure. A placeholder symbol to keep the GLIBC_2.1.1 version alive in libpthread is added with this commit. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

GLIBC_2.1.1 __libpthread_version_placeholder F
nptl: Remove vfork IFUNC-based forwarder from libpthread [BZ #20188] With commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]"), the dynamic linker will find the definition of vfork in libc and binds a vfork reference to that symbol, even if the soname in the version reference says that the symbol should be located in libpthread. As a result, the forwarder (whether it's IFUNC-based or a duplicate of the libc implementation) is no longer necessary. On older architectures, a placeholder symbol is required, to make sure that the GLIBC_2.1.2 symbol version does not go away, or is turned in to a weak symbol definition by the link editor. (The symbol version needs to preserved so that the symbol coverage check in elf/dl-version.c does not fail for old binaries.) mips32 is an outlier: It defined __vfork@@GLIBC_2.2, but the baseline is GLIBC_2.0. Since there are other @@GLIBC_2.2 symbols, the placeholder symbol is not needed there.

GLIBC_2.1.2 __libpthread_version_placeholder F

GLIBC_2.12 __libpthread_version_placeholder F
nptl: Move pthread_getattr_default_np into libc The symbol was moved using scripts/move-symbol-to-libc.py. A new placeholder symbol __libpthread_version_placeholder@GLIBC_2.18 is needed to keep the GLIBC_2.18 symbol version in libpthread. The __pthread_getattr_default_np@@GLIBC_PRIVATE export is used from pthread_create. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

GLIBC_2.18 __libpthread_version_placeholder F
nptl: Move pthread_getcpuclockid into libc The symbol was moved using scripts/move-symbol-to-libc.py. __libpthread_version_placeholder@@GLIBC_2.2 is needed by this change; the Versions entry for GLIBC_2.2 in libpthread had leftover symbols due to an error in a previous conflict resolution. The condition for the placeholder symbol is complicated because some architectures have earlier symbols at the GLIBC_2.2 symbol versions, so the placeholder is not required there (yet).

nptl: Move pthread_gettattr_np into libc This is part of the libpthread removal project: <https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html> Use __getline instead of __getdelim to avoid a localplt failure. Likewise for __getrlimit/getrlimit.

GLIBC_2.2.3 __libpthread_version_placeholder F
nptl: Add more missing placeholder abi symbol from nanosleep move This patch adds the missing __libpthread_version_placeholder for GLIBC_2.2.6 version from the nanosleep implementation move from libpthread to libc (79a547b162). It also fixes the wrong compat symbol definitions added by changing back the version used on vfork check and remove the __libpthread_version_placeholder added on some ABI (4f4bb489e0dd). The __libpthread_version_placeholder is also refactored to make it simpler to add new compat_symbols by adding a new macro compat_symbol_unique which uses the compiler extension __COUNTER__ to generate unique strong alias to be used with compat_symbol. Checked with a updated-abi on the all affected abis of the nanosleep move. Change-Id: I347a4dbdc931bb42b359456932dd1e17aa4d4078

GLIBC_2.28 __libpthread_version_placeholder F
nptl: Move core condition variable functions into libc Onl pthread_cond_clockwait did not have a forwarder, so it needs a new symbol version. Some complications arise due to the need to supply hidden aliases, GLIBC_PRIVATE exports (for the C11 condition variable implementation that still remains in libpthread) and 64-bit time_t stubs. pthread_cond_broadcast, pthread_cond_signal, pthread_cond_timedwait, pthread_cond_wait, pthread_cond_clockwait have been moved using scripts/move-symbol-to-libc.py.
