78e09591a5 Optimize scripts/merge-test-results.sh
The inner loop is called thousands of times per "make check" even
if there's otherwise nothing to do.  Avoid calling /bin/head all
those times when a builtin will do.

33dd32fd79 build-many-glibcs.py: Add a s390x -O3 glibc variant.
On s390x, gcc inlines more aggresive compared to other architectures.
This occaisionally leads to build warnings / errors.

Therefore this patch adds a s390x glibc variant with optimization.

There is the ccopts field which contain ABI options which are passed
to configure as CC / CXX.  Now there is also the cflags field which
contains non-ABI options like -g or -O. Those are passed to configure
as CFLAGS / CXXFLAGS.

Currently CC is passed to conformtest.py or linknamespace.py but not
the CFLAGS.

23a7896d06 Update build-many-glibcs.py for binutils ia64 obsoletion.
Since binutils has obsoleted ia64 support, use --enable-obsolete for
now when configuring binutils for ia64 in build-many-glibcs.py (which
requires adding support for architecture-specific binutils configure
options there).  As with other obsoletions, the removal of support for
ia64 in any of (binutils, GCC, Linux kernel) should imply its removal

5500cdba40 Remove --enable-obsolete-rpc configure flag
Sun RPC was removed from glibc. This includes rpcgen program, librpcsvc,
and Sun RPC headers. Also test for bug #20790 was removed
(test for rpcgen).

Backward compatibility for old programs is kept only for architectures
and ABIs that have been added in or before version 2.28.

libtirpc is mature enough, librpcsvc and rpcgen are provided in
rpcsvc-proto project.

NOTE: libnsl code depends on Sun RPC (installed libnsl headers use
installed Sun RPC headers), thus --enable-obsolete-rpc was a dependency
for --enable-obsolete-nsl (removed in a previous commit).

The arc ABI list file has to be updated because the port was added
with the sunrpc symbols

ae7a94e5e3 Remove --enable-obsolete-nsl configure flag
this means that *always* libnsl is only built as shared library for
backward compatibility and the NSS modules libnss_nis and libnss_nisplus
are not built at all, libnsl's headers aren't installed.

This compatibility is kept only for architectures and ABIs that have
been added in or before version 2.28.

Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>.

This change does not affect libnss_compat which does not depended
on libnsl since 2.27 and thus can be used without NIS.

libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed
libnsl headers use installed Sun RPC headers), which will be removed in
the following commit.

f13d260190 signal: Move sys_errlist to a compat symbol
The symbol is deprecated by strerror since its usage imposes some issues
such as copy relocations.

Its internal name is also changed to _sys_errlist_internal to avoid
static linking usage.  The compat code is also refactored by removing
the over enginered errlist-compat.c generation from manual entried and
extra comment token in linker script file.  It disantangle the code
generation from manual and simplify both Linux and Hurd compat code.

The definitions from errlist.c are moved to errlist.h and a new test
is added to avoid a new errno entry without an associated one in manual.

Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi
on all affected platforms.

076f09afba Linux: Remove <sys/sysctl.h> and the sysctl function
Linux 5.5 remove the system call in commit
61a47c1ad3a4dc6882f01ebdc88138ac62d0df03 ("Linux: Remove
<sys/sysctl.h>").  Therefore, the compat function is just a stub that
sets ENOSYS.

Due to SHLIB_COMPAT, new ports will not add the sysctl function anymore
automatically.

x32 already lacks the sysctl function, so an empty sysctl.c file is
used to suppress it.  Otherwise, a new compat symbol would be added.

f2144b7874 Script to generate ChangeLog-like output from git log
Co-authored-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br>

Reviewed-by: Joseph Myers <joseph@codesourcery.com>

The utility of a ChangeLog file has been discussed in various mailing
list threads and GNU Tools Cauldrons in the past years and the general
consensus is that while the file may have been very useful in the past
when revision control did not exist or was not as powerful as it is
today, it's current utility is fast diminishing.  Further, the
ChangeLog format gets in the way of modernisation of processes since
it almost always results in rewriting of a commit, thus preventing use
of any code review tools to automatically manage patches in the glibc
project.

There is consensus in the glibc community that documentation of why a
change was done (i.e. a detailed description in a git commit) is more
useful than what changed (i.e. a ChangeLog entry) since the latter can
be deduced from the patch.  The GNU community would however like to
keep the option of ascertaining what changed through a ChangeLog-like
output and as a compromise, it was proposed that a script be developed
that generates this output.

The script below is the result of these discussions.  This script
takes two git revisions references as input and generates the git log
between those revisions in a form that resembles a ChangeLog.  Its
capabilities and limitations are listed in a comment in the script.
On a high level it is capable of parsing C code and telling what
changed at the top level, but not within constructs such as functions.

Design
------

At a high level, the script analyses the raw output of a VCS, parses
the source files that have changed and attempts to determine what
changed.  The script driver needs three distinct components to be
fully functional for a repository:

- A vcstocl_quirks.py file that helps it parse weird patterns in
  sources that may result from preprocessor defines.
- A VCS plugin backend; the git backend is implemented for glibc
- A programming language parser plugin.  C is currently implemented.

Additional programming language parsers can be added to give more
detailed output for changes in those types of files.

For input in languages other than those that have a parser, the script
only identifies if a file has been added, removed, modified,
permissions changed, etc. but cannot understand the change in content.

The C Parser
------------

The C parser is capable of parsing C programs with preprocessor macros
in place, as if they were part of the language.  This presents some
challenges with parsing code that expands macros on the fly and to
help work around that, a vcstocl_quirks.py file has transformations to
ease things.

The C parser currently can identify macro definitions and scopes and
all global and static declarations and definitions.  It cannot parse
(and compare) changes inside functions yet, it could be a future
enhancement if the need for it arises.

Testing
-------

The script has been tested with the glibc repository up to glibc-2.29
and also in the past with emacs.  While it would be ideal to have
something like this in a repository like gnulib, that should not be a
bottleneck for glibc to start using this, so this patch proposes to
add these scripts into glibc.

And here is (hopefully!) one of the last ChangeLog entries we'd have
to write for glibc:

	* scripts/gitlog_to_changelog.py: New script to auto-generate
	ChangeLog.
	* scripts/vcs_to_changelog/frontend_c.py: New file.
	* scripts/vcs_to_changelog/misc_util.py: New file.
	* scripts/vcs_to_changelog/vcs_git.py: New file.
	* scripts/vcs_to_changelog/vcstocl_quirks.py: Likewise.

744e829637 Linux: Deprecate <sys/sysctl.h> and sysctl
Now that there are no internal users of __sysctl left, it is possible
to add an unconditional deprecation warning to <sys/sysctl.h>.

To avoid a test failure due this warning in check-install-headers,
skip the test for sys/sysctl.h.

Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*).
GCC 9 dropped support for the SPE extensions to PowerPC, which means
powerpc*-*-*gnuspe* configurations are no longer buildable with that
compiler.  This ISA extension was peculiar to the “e500” line of
embedded PowerPC chips, which, as far as I can tell, are no longer
being manufactured, so I think we should follow suit.

This patch was developed by grepping for “e500”, “__SPE__”, and
“__NO_FPRS__”, and may not eliminate every vestige of SPE support.
Most uses of __NO_FPRS__ are left alone, as they are relevant to
normal embedded PowerPC with soft-float.

        * sysdeps/powerpc/preconfigure: Error out on powerpc-*-*gnuspe*
        host type.
        * scripts/build-many-glibcs.py: Remove powerpc-*-linux-gnuspe
        and powerpc-*-linux-gnuspe-e500v1 from list of build configurations.
