This patch moves the __PTHREAD_SPINS definition to arch specific header since pthread_mutex_t layout is also arch specific. This leads to no need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the undefined compiler warning. |

This is the glibc ports add-on, an add-on for the GNU C Library (glibc). It contains code that is not maintained in the official glibc source tree. This includes working ports to GNU/Linux on some machine architectures that are not maintained in the official glibc source tree. It also includes some code once used by old libc ports now defunct, which has been abandoned but may be useful for some future porter to examine. It may also include some optimized functions tailored for specific CPU implementations of an architecture, to be selected using --with-cpu. The ports add-on is cooperatively maintained by volunteers on the <libc-ports@sourceware.org> mailing list, and housed in the ports subdirectory of the glibc git repository. See http://www.gnu.org/software/libc/download.html for details on using git. To report a bug in code housed in the ports add-on, please go to http://sourceware.org/bugzilla/ and file a bug report under the glibc "ports" component. An add-on for an individual port can be made from just the sysdeps/ subdirectories containing the port's code. You may want to include a README and Banner of your own talking about your port's code in particular, rather than the generic ones here. The real source code for any ports is found in the sysdeps/ subdirectories. These should be exactly what would go into the main libc source tree if you were to incorporate it directly. The only exceptions are the files sysdeps/*/preconfigure and sysdeps/*/preconfigure.ac; these are fragments used by this add-on's configure fragment. The purpose of these is to set $base_machine et al when the main libc configure's defaults are not right for some machine. Everything else can and should be done from a normal sysdeps/.../configure fragment that is used only when the configuration selects that sysdeps subdirectory. Each port that requires some special treatment before the sysdeps directory list is calculated, should add a sysdeps/CPU/preconfigure file; this can either be written by hand or generated by Autoconf from sysdeps/CPU/preconfigure.ac, and follow the rules for glibc add-on configure fragments. No preconfigure file should do anything on an unrelated configuration, so that disparate ports can be put into a single add-on without interfering with each other. Like all glibc add-ons, this must be used by specifying the directory in the --enable-add-ons option when running glibc's configure script. The GNU C Library is free software. See the file COPYING.LIB in the libc repository 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., 2000-2013, indicating that every year in the range, inclusive, is a copyrightable year that would otherwise be listed individually.
