This patch removes CALL_THREAD_FCT macro usage and its defition for
x86. For 32 bits it usage is only for force 16 stack alignment,
however stack is already explicit aligned in clone syscall. For
64 bits and x32 it just a function call and there is no need to
code it with inline assembly.
Checked on i686-linux-gnu, x86_64-linux-gnu, and x86_64-linux-gnu-x32.
* nptl/pthread_create.c (START_THREAD_DEFN): Remove
CALL_THREAD_FCT macro usage.
* sysdeps/i386/nptl/tls.h (CALL_THREAD_FCT): Remove definition.
* sysdeps/x86_64/nptl/tls.h (CALL_THREAD_FCT): Likewise.
* sysdeps/x86_64/32/nptl/tls.h: Remove file.
This directory contains the sources of the GNU C Library.
See the file "version.h" for what release version you have.
The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system. It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.
In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.
The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[4567]86-*-gnu. The current
GNU/Hurd support requires out-of-tree patches that will eventually be
incorporated into an official GNU C Library release.
When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 3.2 or later on all architectures except
i[4567]86 and x86_64, where Linux kernel version 2.6.32 or later
suffices.
Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.
The GNU C Library supports these configurations for using Linux kernels:
aarch64*-*-linux-gnu
alpha*-*-linux-gnu
arm-*-linux-gnueabi
hppa-*-linux-gnu Not currently functional without patches.

If you are interested in doing a port, please contact the glibc
maintainers; see http://www.gnu.org/software/libc/ for more
information.
See the file INSTALL to find out how to configure, build, and install
the GNU C Library. You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.
The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory. The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like. For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below. Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.
Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information. We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.
The GNU C Library is free software. See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed. License copyright years may be
listed using range notation, e.g., 1996-2015, indicating that every year in
the range, inclusive, is a copyrightable year that would otherwise be listed
individually.
