This reverts commit 84e93afc7 ("Switch to UTF-8 for INSTALL") and
reinstates commit c14f2e4aa ("Make sure INSTALL is ASCII plaintext")
and regenerates INSTALL.
It turns out that different versions of makeinfo (texinfo/texi2any),
at least versions 7.0.3 and 7.1, put unicode quote glyphs in different
places (specifically whether contractions like you'd, don't, aren't or
you'll use ’ or '). This breaks the make dist target as used for
(snapshot) releases, which have a check on the regenerated INSTALL
file. Using --disable-encoding generates the same plaintext ASCII on
all versions.
An alternative would be to regenerate INSTALL with texinfo 7.1 and
require at least that version. But that seems too soon while various
distros don't have 7.1 yet. We can try again to use UTF-8 for INSTALL
in a couple of years.

The years of dealing with Binutils, GCC and GDB test results
made the community create good tools for comparison and analysis
of DejaGnu test results. This change allows to use those tools
for Glibc's test results as well.
The motivation for this change is Linaro's pre-commit testers,
which use a modified version of GCC's validate_failures.py
to create test xfail lists with baseline failures and known
flaky tests. See below links for an example xfails file (only
one link is supposed to work at any given time):

When building the testroot, the script runs the newly built ld.so on a
couple of binaries in order to copy over any additional libraries
needed. However, if the dependencies are found in the system cache, it
will be copied over using that path.
This is problematic if the system ld.so and the one built don't have the
exact same search configuration. We encountered this in Ubuntu, where we
build a variant of libc with -fno-omit-frame-pointer for accurate
performance profiling.
This variant is built using a non-standard slibdir to be able to be
co-installed with the default library (e.g. slibdir = /lib/libc6-prof).
Since we have /lib pointing to /usr/lib, any additional dependency
should still be reachable via /usr. However, resolving via the cache
might result in the additional DSOs being copied into $testroot/lib, out
of the search path in the container.
The problem has been triggered by 1d5024f4f052c12e404d42d3b5bfe9c3e9fd27c4
("support: Build with exceptions and asynchronous unwind tables [BZ #30587]")
which introduced a dependency on libgcc_s.so.1 under some circumstances.

We add a 'make check' test that lints all Makefiles in the source
directory of the glibc build. This linting test ensures that the
lines in all Makefiles will be sorted correctly as developers
creates patches. It is added to 'make check' because it is
light-weight and supports the existing developer workflow
The test adds ~3s to a 'make check' execution.

A new build flag, _TIME_BITS, enables the usage of the newer 64-bit
time symbols for legacy ABI (where 32-bit time_t is default). The 64
bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is
also used.
Different than LFS support, the y2038 symbols are added only for the
required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32,
mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with
64-bit time support are unchanged, both for symbol and types
redirection.
On Linux the full 64-bit time support requires a minimum of kernel
version v5.1. Otherwise, the 32-bit fallbacks are used and might
results in error with overflow return code (EOVERFLOW).
The i686-gnu does not yet support 64-bit time.

Expand the support infrastructure:
- Create $(complocaledir) in the testroot.pristine to support localedef.
- Add the variable $complocaledir to script support.
- Add the script command 'mkdirp'.
All localedef tests which run with default paths need to have the
$(complocaledir) created in testroot.pristine. The localedef binary
will not by itself create the default path, but it will write into
the path. By adding this we can simplify the localedef tests.
The variable $complocaledir is the value of the configured
$(complocaledir) which is the location of the compiled locales that
will be searched by the runtime by default.
The command mkdirp will be available in script setup and will
be equivalent to running `mkdir -p`.
The variable and command can be used to write more complex tests.

Debugging programs that have been dynamically linked against an
uninstalled glibc requires unusual steps, such as letting gdb know where
the thread db library is located and explicitly calling the loader.
However, when the program under test is statically linked, these steps
are not required (as a matter of fact, using the dynamic loader to run a
statically linked program is wrong and will fail), and gdb should be
called the usual way.
This patch modifies debugglibc.sh so that it checks if the program under
test is statically linked, then runs the debugger appropriately.

Some test cases are meant to be ran inside the container infrastructure
and make check automatically runs them as such. However, running a
single test case in a container without make check is useful.
This patch adds a new --tool option to testrun.sh that makes this easy,
as well as it adds a new option (-c or --in-container) to debugglibc.sh,
which causes the program under test to be ran in a container (with
WAIT_FOR_DEBUGGER=1), then automatically attaches GDB to it.
Automatically detecting if a test case is supposed to be ran inside a
container is harder (if not impossible), as Carlos pointed out [1],
however, this patch makes it easier to do it manually:
Using testrun.sh with containerized test:
$ ./testrun.sh --tool=container /absolute/path/to/program
Using debugglibc.sh with containerized test:
$ ./debugglibc.sh -c /absolute/path/to/program
Note: running these commands with relative paths causes error and
warning messages to be displayed, although the test case might succeed.
For example, with relative path:
$ ./testrun.sh --tool=container elf/tst-ldconfig-bad-aux-cache
error: subprocess failed: execv
error: unexpected error output from subprocess
/sbin/ldconfig: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf: No such file or directory
info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache
[...]
Whereas with absolute paths, the errors and warnings are gone:
$ ./testrun.sh --tool=container $PWD/elf/tst-ldconfig-bad-aux-cache
info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache

This patch addresses an issue reported in
<https://sourceware.org/ml/libc-alpha/2019-07/msg00661.html> where the
creation of testroot.pristine, on encountering
LD_TRACE_LOADED_OBJECTS=1 of the form
libc.so.6 => /scratch/jmyers/glibc/mbs/obj/glibc-8-0-mips64-linux-gnu-x86_64-linux-gnu/default/libc.so.6 (0x772dd000)

tries to copy /lib32/ld.so.1 (which does not exist) into the testroot
instead of copying the path on the RHS of "=>", which does exist,
because the Makefile logic assumes that the path on such a line with
'/' should be copied, when if there are such paths on both the LHS and
the RHS of "=>", only the one on the RHS necessarily exists and so
only that should be copied. The patch follows the approach suggested
by DJ in <https://sourceware.org/ml/libc-alpha/2019-07/msg00662.html>,
with the suggestion from Andreas in
<https://sourceware.org/ml/libc-alpha/2019-10/msg00514.html> of a
single sed command in place of pipeline of grep and three sed
commands.
Tested for x86_64, with and without --enable-hardcoded-path-in-tests;
a previous version with multiple sed commands, implementing the same
logic, also tested for MIPS, with and without
--enable-hardcoded-path-in-tests, to confirm it fixes the original

This patch adds a new make rule that generates a helper script for
debugging glibc test cases. The new script, debugglibc.sh, is similar
to testrun.sh, in the sense that it allows the execution of the
specified test case, however, it opens the test case in GDB, setting the
library path the same way that testrun.sh does. The commands are based
on the instructions on the wiki for glibc debugging [1,2].
By default, the script tells GDB to load the test case for symbol
information, so that, when a breakpoint is hit, the call stack is
displayed correctly (instead of printing lots of '??'s). For instance,
after running 'make' and 'make check', one could do the following:
$ ./debugglibc.sh nptl/tst-exec1 -b pthread_join
Reading symbols from /home/gabriel/build/powerpc64le/glibc//elf/ld.so...done.
Breakpoint 1 at 0x1444

Breakpoint 2 at 0x7ffff7f49d48: file pthread_join.c, line 23.
Notice that the script will always start GDB with the program running
and halted at _dl_start_user. So, in order to reach the actual
breakpoint of interest, one should hit 'c', not 'r':
>>> c

Whenever a sub-make is created, it inherits the variable subdirs from its
parent. This is also true when make check is called with a restricted
list of subdirs. In this scenario, make install is executed "partially"
and testroot.pristine ends up with an incomplete installation.

Some DSOs are distributed in hardware capability directories, e.g.
/usr/lib64/power7/libc.so.6
Whenever the processor is able to use one of these hardware-enabled
DSOs, testroot.pristine ends up with copies of glibc-provided libraries
from the system because it can't overwrite or remove them.
This patch avoids the unintended copies by executing ld.so with the same
arguments passed to each glibc test.

If building on a subset of architectures only, it is easy to miss
wrapper headers which are required by other architectures because
they lack the corresponding sysdeps header. The check ensures
that every installed header which is not itself a sysdeps header
has a header under include/ (that presumably wraps the header,
and perhaps also adding declarations and definitions for !_ISOMAC).
Also check for the absence of the sysdeps/generic/bits directory
removed in commit c72565e5f1124c2dc72573e83406fe999e56091f, to make
accidental re-introduction more difficult.
