From e64ac02c24b43659048622714afdc92fedf561fa Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Sun, 1 Jul 2012 13:06:41 +0000 Subject: Move all files into ports/ subdirectory in preparation for merge with glibc --- ports/README | 50 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 ports/README (limited to 'ports/README') diff --git a/ports/README b/ports/README new file mode 100644 index 0000000000..51e0a303b6 --- /dev/null +++ b/ports/README @@ -0,0 +1,50 @@ +This is the glibc ports repository, 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 repository is cooperatively maintained by volunteers on the + mailing list, and housed in a separate +ports 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 repository, please +go to http://sources.redhat.com/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.in; 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.in, 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. Files that +would go in scripts/data/ for libc go in data/ in ports. + +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., 2000-2011, indicating that every year in the range, +inclusive, is a copyrightable year that would otherwise be listed +individually. -- cgit v1.2.3
