Author: sjhill
Date: 2005-12-05 18:32:21 -0800 (Mon, 05 Dec 2005)
New Revision: 12677

Log:
Remove unused source files and other extraneous glibc files. If you want to understand the design, go read it in the glibc stuff. uClibc is all about size, including the tarball.

-Now that the Linux kernel is once again able to run all the tests we
-have and since glibc 2.3 was released it was time for a new code drop.
-I've uploaded the second code drop for the Native POSIX Thread
-Library:
-
-  ftp://people.redhat.com/drepper/nptl/nptl-0.2.tar.bz2
-
-You need
-
-- the latest of Linus' kernel from BitKeeper (or 2.5.41 when it
-  is released);
-
-- glibc 2.3
-
-- the very latest in tools such as
-
-  + gcc either from the current development branch or the gcc 3.2
-    from Red Hat Linux 8;
-
-  + binutils preferrably from CVS, from H.J. Lu's latest release for
-    Linux, or from RHL 8.
-
-
-Compiling glibc should proceed smoothly.  But there are a number of
-tests which fail, mostly because some functionality is missing in
-glibc.  Ignore those errors.  It is only important that all tests in
-nptl/ are passing.  Run
-
-  make subdirs=nptl check
-
-to run all thread tests.
-
-
-This version features several improvements:
-
-- all APIs are now implemented;
-
-- fork handling has been improved; stacks in the child are freed;
-  atfork handlers are removed if they were registered from a module
-  which gets unloaded.
-
-- pthread_tryjoin_np and pthread_timedjoin_np are implemented
-
-- TSD handling corrected and optimized.
-
-- many more tests which also test the underlying kernel implementation.
-
-- the build infrastructure has been implemented so that the DSO and
-  archives are built in usable form and with correct named.
-
-- libthread_db has been implemented.  This is the library which is
-  needed by all program which need to get access to internals of
-  libpthread (mainly debuggers).
-
-- the CPU clock functions are implemented
-
-
-
-The white paper hasn't yet been updated.  It's still available at
-
-  http://people.redhat.com/drepper/nptl-design.pdf
-
-
-This release should be ready for some serious testing.  I know it is
-hard to compile which I why I'm looking into providing binary RPMs.
-They can be used on non-critical systems.  I'll only be able to
-provide binaries for RHL8 based systems, though, and the kernel still
-must be installed separately.
-
-
-The next steps will include:
-
-- write more tests and fix the bugs which are discovered this way
-
-- update the white paper
-
-- write and run more performance tests
-
-- port to IA-64
-
