Continuing the process of building up and using Python infrastructure
for extracting and using values in headers, this patch adds a test
that MAP_* constants from sys/mman.h agree with those in the Linux
kernel headers. (Other sys/mman.h constants could be added to the
test separately.)
This set of constants has grown over time, so the generic code is
enhanced to allow saying extra constants are OK on either side of the
comparison (where the caller sets those parameters based on the Linux
kernel headers version, compared with the version the headers were
last updated from). Although the test is a custom Python file, my
intention is to move in future to a single Python script for such
tests and text files it takes as inputs, once there are enough
examples to provide a guide to the common cases in such tests (I'd
like to end up with most or all such sets of constants copied from
kernel headers having such tests, and likewise for structure layouts
from the kernel).
The Makefile code is essentially the same as for tst-signal-numbers,
but I didn't try to find an object file to depend on to represent the
dependency on the headers used by the test (the conform/ tests don't
try to represent such header dependencies at all, for example).
Tested with build-many-glibcs.py, and also for x86_64 with older
kernel headers.

This patch eliminates the gen-py-const.awk variant of gen-as-const,
switching to use of gnu-as-const.py (with a new --python option) to
process .pysym files (i.e., to generate nptl_lock_constants.py), as
the syntax of those files is identical to that of .sym files.
Note that the generated nptl_lock_constants.py is *not* identical to
the version generated by the awk script. Apart from the trivial
changes (comment referencing the new script, and output being sorted),
the constant FUTEX_WAITERS, PTHREAD_MUTEXATTR_FLAG_BITS,
PTHREAD_MUTEXATTR_FLAG_PSHARED and PTHREAD_MUTEX_PRIO_CEILING_MASK are
now output as positive rather than negative constants (on x86_64
anyway; maybe not necessarily on 32-bit systems):
< FUTEX_WAITERS = -2147483648
---
> FUTEX_WAITERS = 2147483648
< PTHREAD_MUTEXATTR_FLAG_BITS = -251662336
< PTHREAD_MUTEXATTR_FLAG_PSHARED = -2147483648
---
> PTHREAD_MUTEXATTR_FLAG_BITS = 4043304960
> PTHREAD_MUTEXATTR_FLAG_PSHARED = 2147483648
< PTHREAD_MUTEX_PRIO_CEILING_MASK = -524288
---
> PTHREAD_MUTEX_PRIO_CEILING_MASK = 4294443008
This is because gen-as-const has a cast of the constant value to long
int, which gen-py-const lacks.
I think the positive values are more logically correct, since the
constants in question are in fact unsigned in C. But to reliably
produce gen-as-const.py output for constants that always (in C and
Python) reflects the signedness of values with the high bit of "long
int" set would mean more complicated logic needs to be used in
computing values.
The more correct positive values by themselves produce a failure of
nptl/test-mutexattr-printers, because masking with
~PTHREAD_MUTEXATTR_FLAG_BITS & ~PTHREAD_MUTEX_NO_ELISION_NP now leaves
a bit -1 << 32 in the Python value, resulting in a KeyError exception.
To avoid that, places masking with ~ of one of the constants in
question are changed to mask with 0xffffffff as well (this reflects
how ~ in Python applies to an infinite-precision integer whereas ~ in
C does not do any promotions beyond the width of int).
Tested for x86_64.

This patch converts the tst-signal-numbers test from shell + awk to
Python.
As with gen-as-const, the point is not so much that shell and awk are
problematic for this code, as that it's useful to build up general
infrastructure in Python for use of a range of code involving
extracting values from C headers. This patch moves some code from
gen-as-const.py to a new glibcextract.py, which also gains functions
relating to listing macros, and comparing the values of a set of
macros from compiling two different pieces of code.
It's not just signal numbers that should have such tests; pretty much
any case where glibc copies constants from Linux kernel headers should
have such tests that the values and sets of constants agree except
where differences are known to be OK. Much the same also applies to
structure layouts (although testing those without hardcoding lists of
fields to test will be more complicated).
Given this patch, another test for a set of macros would essentially
be just a call to glibcextract.compare_macro_consts (plus boilerplate
code - and we could move to having separate text files defining such
tests, like the .sym inputs to gen-as-const, so that only a single
Python script is needed for most such tests). Some such tests would
of course need new features, e.g. where the set of macros changes in
new kernel versions (so you need to allow new macro names on the
kernel side if the kernel headers are newer than the version known to
glibc, and extra macros on the glibc side if the kernel headers are
older). tst-syscall-list.sh could become a Python script that uses
common code to generate lists of macros but does other things with its
own custom logic.
There are a few differences from the existing shell + awk test.
Because the new test evaluates constants using the compiler, no
special handling is needed any more for one signal name being defined
to another. Because asm/signal.h now needs to pass through the
compiler, not just the preprocessor, stddef.h is included as well
(given the asm/signal.h issue that it requires an externally provided
definition of size_t). The previous code defined __ASSEMBLER__ with
asm/signal.h; this is removed (__ASSEMBLY__, a different macro,
eliminates the requirement for stddef.h on some but not all
architectures).
Tested for x86_64, and with build-many-glibcs.py.

It was reported in
<https://sourceware.org/ml/libc-alpha/2018-12/msg00045.html> that
gen-as-const.py fails to generate test code in the case where a .sym
file has no symbols in it, so resulting in a test failing to link for
Hurd.
The relevant difference from the old awk script is that the old script
treated '--' lines as indicating that the text to do at the start of
the test (or file used to compute constants) should be output at that
point if not already output, as well as treating lines with actual
entries for constants like that. This patch changes gen-as-const.py
accordingly, making it the sole responsibility of the code parsing
.sym files to determine when such text should be output and ensuring
it's always output at some point even if there are no symbols and no
'--' lines, since not outputting it means the test fails to link.
Handling '--' like that also avoids any problems that would arise if
the first entry for a symbol were inside #ifdef (since the text in
question must not be output inside #ifdef).
Tested for x86_64, and with build-many-glibcs.py for i686-gnu. Note
that there are still compilation test failures for i686-gnu
(linknamespace tests, possibly arising from recent posix_spawn-related
changes).
* scripts/gen-as-const.py (compute_c_consts): Take an argument
'START' to indicate that start text should be output.
(gen_test): Likewise.
(main): Generate 'START' for first symbol or '--' line, or at end
of input if not previously generated.

hurd's jmp_buf-ssp.sym does not define any symbol.
scripts/gen-as-const.py currently was emitting an empty line in that
case, and the gawk invocation was prepending "asconst_" to it, ending up
with:
.../build/glibc/setjmp/test-as-const-jmp_buf-ssp.c:1:2: error: expected « = », « , », « ; », « asm » or
« __attribute__ » at end of input
1 | asconst_
| ^~~~~~~~
* scripts/gen-as-const.py (main): Avoid emitting empty line when
there is no element in `consts'.
|

Hurd has this in libc.so:
0024db9c g D .bss 00000000 GLIBC_2.2.6 _end
This g/D combination was not recognized before.

This patch replaces gen-as-const.awk, and some fragments of the
Makefile code that used it, by a Python script. The point is not such
much that awk is problematic for this particular script, as that I'd
like to build up a general Python infrastructure for extracting
information from C headers, for use in writing tests of such headers.
Thus, although this patch does not set up such infrastructure, the
compute_c_consts function in gen-as-const.py might be moved to a
separate Python module in a subsequent patch as a starting point for
such infrastructure.
The general idea of the code is the same as in the awk version, but no
attempt is made to make the output files textually identical. When
generating a header, a dict of constant names and values is generated
internally then defines are printed in sorted order (rather than the
order in the .sym file, which would have been used before). When
generating a test that the values computed match those from a normal
header inclusion, the test code is made into a compilation test using
_Static_assert, where previously the comparisons were done only when
the test was executed. One fragment of test generation (converting
the previously generated header to use asconst_* prefixes on its macro
names) is still in awk code in the makefiles; only the .sym processing
and subsequent execution of the compiler to extract constants have
moved to the Python script.
Tested for x86_64, and with build-many-glibcs.py.
* scripts/gen-as-const.py: New file.
* scripts/gen-as-const.awk: Remove.

These files were both auto-generated and shipped in the source tree.
We can assume that sed is available and always generate the files
during the build.

Now that build-many-glibcs.py touches at checkout time all files that
might get rebuilt in the glibc source directory in a normal glibc
build and test run, this patch stops the script from copying the glibc
source directory, so that all builds use the original directory
directly (and less disk space is used, less I/O is involved and cached
copies of the sources in memory can be shared between all the builds -
as well as avoiding spurious failures from copying while "git gc" is
running). This is similar to how all other components were already
handled. Any bugs involving writing into the source directory can be
dealt with in future as normal bugs, just as such bugs already are
handled.
Tested with build-many-glibcs.py runs with a read-only glibc source
directory, with all files not touched by the script having timestamps
in forwards alphabetical order and separately with all files not
touched by the script having timestamps in backwards alphabetical
order.
* scripts/build-many-glibcs.py (Glibc.build_glibc): Use original
source directory instead of a copy.
(CommandList.create_copy_dir): Remove.

Mathieu Desnoyers ran into an issue with his rseq patch where he
was the first person to add weak thread-local data and this
resulted in an ABI list update with entries like this:
"GLIBC_2.29 w ? D .tdata 0000000000000020".
The weakness of the symbol has nothing to do with the DSOs ABI
and so we should not write anything about weak symbols here. The
.tdata entries should be treated exactly like .tbss entries and
the output should have been: "GLIBC_2.29 __rseq_abi T 0x20"
This change makes abilist.awk handle .tdata just like .tbss,
while at the same time adding an error case for the default, and
the unknown line cases. We never want anyone to be able to add
such entries to any ABI list files and should see an immediate
error and consult with experts.
Tested by Mathieu Desnoyers <mathieu.desnoyers@efficios.com> with
the rseq patch set and 'make update-all-abi'.
Tested myself with 'make update-all-abi' on x86_64 with no
changes.

build-many-glibcs.py currently copies the source tree to avoid issues
with parallel builds trying to write into it. This copying can result
in occasional spurious build failures from bots, when a "git gc" is in
progress that changes .git contents while copying is taking place, and
it would also be desirable to avoid the need to copy to save on disk
space, I/O and memory used in build-many-glibcs.py builds.
In preparation for removing the copying, this patch arranges for
build-many-glibcs.py to touch more files on checkout so their
timestamps do not result in make attempting to rebuild them. Before
actually removing the copying, I intend to do further tests to ensure
I haven't missed any other such makefile dependencies.
This is of course without prejudice to possibly moving more of these
files to being generated in the build directory rather than being
checked in at all, where that can be done using build tools already
required for the build. For sysdeps files (installed and otherwise)
it would be necessary to make sure this does not affect the search
ordering, for headers used in the build it would be necessary to
ensure they are generated early enough, and for errlist.c there may be
dual licensing reasons for keeping it checked in.
Tested that a checkout with build-many-glibcs.py does touch the
expected files and that a glibcs build for aarch64-linux-gnu succeeds.

Since we have consensus on requiring Python 3.4 or later to build
glibc, it follows that compatibility with older Python versions is
also no longer relevant to auxiliary Python scripts for use in glibc
development. This patch removes such compatibility code from
build-many-glibcs.py (compatibility code needed for 3.4, which lacks
the newer subprocess interface, is kept). Because
build-many-glibcs.py is not itself called from the glibc build system,
this patch is independent of the configure checks for having a
new-enough Python version, which are only relevant to uses of Python
from the main build and test process.
Tested with build-many-glibcs.py building glibc for aarch64-linux-gnu
(with Python 3.4 to make sure that still works).
* scripts/build-many-glibcs.py: Remove compatibility for missing
os.cpu_count and re.fullmatch.

For architectures and ABIs that are added in version 2.29 or later the

compatibility library is built.

Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =
| ^
* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for

We've had issues before with build failures (with new GCC) in code
only built with --enable-obsolete-rpc or --enable-obsolete-nsl not
being reported for a while because build-many-glibcs.py does not test

64-bit) using those options so that in future we can notice quickly if
they start failing to build.
Tested the new configurations do build with GCC 8.

As noted in bug 13888, and as I noted previously in
<https://sourceware.org/ml/libc-alpha/2000-10/msg00111.html>, various
tests used hardcoded paths in /tmp, so posing issues for simultaneous
test runs from different build directories.
This patch fixes such uses of hardcoded file names to put them in the
build directory instead (in the case of stdio-common/bug5 the file
names are changed as well, to avoid a conflict with the name bug5.out
also used for the automatic test output redirection). It also fixes
test-installation.pl likewise (that was using filenames with $$ in
them rather than strictly hardcoded names, but that's still not good
practice for temporary file naming).
Note that my list of files changed is not identical to that in bug
13888. I added tst-spawn3.c and test-installation.pl, and removed
some tests that seem to me (now) to create temporary files securely
(simply using /tmp is not itself a problem if the temporary files are
handled properly with mkstemp; I haven't checked whether those tests
used to do things insecurely). conformtest is not changed because the
makefiles always pass a --tmpdir option so the /tmp default is
irrelevant, and for the same reason there is no actual problem with
nptl/tst-umask1.c because again the makefiles always override the
default.
nptl/sockperf.c is ignored because there is no code to run it;
probably that file should actually be removed.
Some tests use the mktemp function, but I think they all use it in a
way that *is* secure (for generating names for directories / sockets /
fifos / symlinks, where the operation using the name will not follow
symlinks and so there is no potential for a symlink attack on the
account running the testsuite).
Some tests use the tmpnam function to generate temporary file names.
This is in principle insecure, but not addressed by this patch (I
consider it a separate issue from the fully hardcoded paths).
Tested for x86_64.

A recent binutils patch
<https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the
MIPS linker including the _gp_disp absolute symbol in dynamic symbol
tables.
With older binutils, it is included for MIPS o32 (despite the use of
symbol versioning), and this means that all the ABI test baselines for
MIPS o32 include "_gp_disp _gp_disp A". This symbol is not
meaningfully part of the ABI for shared libraries, since it always has
to be resolved at static link time to the local definition for the
linked object.
All the other absolute symbols in ABI test baselines are the names of
symbol versions. I don't think the mere existence of a symbol version
with a given name - as opposed to the contents of that version if
nonempty - is part of the ABI either. Thus, this patch allows the ABI
tests to pass both before and after the binutils change by changing
abilist.awk not to include absolute symbols in its output, and
changing the baselines accordingly.
Tested for x86_64, and with build-many-glibcs.py.

Since tile support has been removed from the Linux kernel for 4.17,
this patch removes the (unmaintained) port to tilegx from glibc (the
tilepro support having been previously removed). This reflects the
general principle that a glibc port needs upstream support for the
architecture in all the components it build-depends on (so binutils,
GCC and the Linux kernel, for the normal case of a port supporting the
Linux kernel but no other OS), in order to be maintainable.
Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile,
there are updates to various comments referencing tile for which
removal of those references seemed appropriate. The configuration is
removed from README and from build-many-glibcs.py. contrib.texi keeps
mention of removed contributions, but I updated Chris Metcalf's entry
to reflect that he also contributed the non-removed support for the
generic Linux kernel syscall interface.
__ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used
by tile.
* sysdeps/tile: Remove.
* sysdeps/unix/sysv/linux/tile: Likewise.
* README (tilegx-*-linux-gnu): Remove from list of supported
configurations.
* manual/contrib.texi (Contributors): Mention Chris Metcalf's
contribution of support for generic Linux kernel syscall
interface.

Now that GCC 8 has branched, this patch makes build-many-glibcs.py
default to using GCC 8 branch instead of GCC 7. The effect should be
that all builds complete cleanly and the compilation parts of the
glibc testsuite complete cleanly except for on i686-gnu (with GCC 7
there were testsuite failures for some other configurations as well).
I've replaced my bot building using GCC 6 branch with one using GCC 8
branch. (Of course glibc should continue building with GCC 6 - and
for that matter GCC 5 and 4.9, which are no longer maintained, are
supported versions as well - but building with GCC 6 will no longer be
included in my bot testing.)
* scripts/build-many-glibcs.py (Context.checkout): Default GCC
version to GCC 8 branch.

If e.g. the testcase nptl/test-mutex-printers is run
with enabled lock-elision, it fails on s390x with:
Error: Response does not match the expected pattern.
Command: print *mutex
Expected pattern: pthread_mutex_t
Response: No symbol "mutex" in current context.
(gdb)
See https://www.sourceware.org/ml/libc-alpha/2018-03/msg00583.html
for more details.
In fact the mutex pretty printer tests rely on looking at the
internal details of the lock, thus we disable it by setting up
the GLIB_TUNABLES environment variable inside gdb.
ChangeLog:
* scripts/test_printers_common.py (init_test): Disable lock elision.

The powerpcspe GCC port has been obsoleted in GCC 8 for not having had
the removal of code for non-SPE processors completed. This patch
accordingly arranges for build-many-glibcs.py to configure GCC with
--enable-obsolete for affected configurations. This is temporary;
either the port gets cleaned up and unobsoleted in GCC and the
configure option can be removed, or the port gets removed in GCC and
we should remove the corresponding glibc support.
Tested with build-many-glibcs.py for the affected configurations.
* scripts/build-many-glibcs.py (Context.add_all_configs): Use
--enable-obsolete for powerpc-linux-gnuspe.

We shipped 2.27 with libio.h and _G_config.h still installed but
issuing warnings when used. Let's stop installing them early in 2.28
so that we have plenty of time to think of another plan if there are
problems.
The public stdio.h had a genuine dependency on libio.h for the
complete definitions of FILE and cookie_io_functions_t, and a genuine
dependency on _G_config.h for the complete definitions of fpos_t and
fpos64_t; these are moved to single-type headers.
bits/types/struct_FILE.h also provides a handful of accessor and
bitflags macros so that code is not duplicated between bits/stdio.h
and libio.h. All the other _IO_ and _G_ names used by the public
stdio.h can be replaced with either public names or __-names.
In order to minimize the risk of breaking our own compatibility code,
bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism
exactly as it was in libio.h, but you have to define _LIBC to use it,
or it'll error out. Similarly, _IO_lock_t_defined is preserved
exactly, but will error out if used without defining _LIBC.
Internally, include/stdio.h continues to include libio.h, and libio.h
scrupulously provides every _IO_* and _G_* name that it always did,
perhaps now defined in terms of the public names. This is how this
patch avoids touching dozens of files throughout glibc and becoming
entangled with the _IO_MTSAFE_IO mess. The remaining patches in this
series eliminate most of the _G_ names.
Tested on x86_64-linux; in addition to the test suite, I installed the
library in a sysroot and verified that a simple program that uses
stdio.h could be compiled against the installed library, and I also
verified that installed stripped libraries are unchanged.
* libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h:
New single-type headers split from _G_config.h.
* libio/bits/types/cookie_io_functions_t.h
* libio/bits/types/struct_FILE.h
New single-type headers split from libio.h.
* libio/Makefile: Install the above new headers. Don't install
libio.h, _G_config.h, bits/libio.h, bits/_G_config.h, or
bits/libio-ldbl.h.
* libio/_G_config.h, libio/libio.h: Delete file.
* libio/bits/libio.h: Remove improper-inclusion guard.
Include stdio.h and don't repeat anything that it does.
Define _IO_fpos_t as __fpos_t, _IO_fpos64_t as __fpos64_t,
_IO_BUFSIZ as BUFSIZ, _IO_va_list as __gnuc_va_list,
__io_read_fn as cookie_read_function_t,
__io_write_fn as cookie_write_function_t,
__io_seek_fn as cookie_seek_function_t,
__io_close_fn as cookie_close_function_t,
and _IO_cookie_io_functions_t as cookie_io_functions_t.
Define _STDIO_USES_IOSTREAM, __HAVE_COLUMN, and _IO_file_flags
here, in the "compatibility defines" section. Remove an #if 0
block. Use the "body" macros from bits/types/struct_FILE.h to
define _IO_getc_unlocked, _IO_putc_unlocked, _IO_feof_unlocked,
and _IO_ferror_unlocked.
Move prototypes of __uflow and __overflow...
* libio/stdio.h: ...here. Don't include bits/libio.h.
Don't define _STDIO_USES_IOSTREAM. Get __gnuc_va_list
directly from stdarg.h. Include bits/types/__fpos_t.h,
bits/types/__fpos64_t.h, bits/types/struct_FILE.h,
and, when __USE_GNU, bits/types/cookie_io_functions_t.h.
Use __gnuc_va_list, not _G_va_list; __fpos_t, not _G_fpos_t;
__fpos64_t, not _G_fpos64_t; FILE, not struct _IO_FILE;
cookie_io_functions_t, not _IO_cookie_io_functions_t;
__ssize_t, not _IO_ssize_t. Unconditionally define
BUFSIZ as 8192 and EOF as (-1).
* libio/bits/stdio.h: Add multiple-include guard. Use the "body"
macros from bits/types/struct_FILE.h instead of _IO_* macros
from libio.h; use __gnuc_va_list instead of va_list and __ssize_t
instead of _IO_ssize_t.
* libio/bits/stdio2.h: Similarly.
* libio/iolibio.h: Add multiple-include guard.
Include bits/libio.h after stdio.h.
* libio/libioP.h: Add multiple-include guard.
Include stdio.h and bits/libio.h before iolibio.h.
* include/bits/types/__fpos_t.h, include/bits/types/__fpos64_t.h
* include/bits/types/cookie_io_functions_t.h
* include/bits/types/struct_FILE.h: New wrappers.
* bits/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h:
Get definitions of _G_fpos_t and _G_fpos64_t from
bits/types/__fpos_t.h and bits/types/__fpos64_t.h
respectively. Remove improper-inclusion guards.
* conform/data/stdio.h-data: Update expectations of va_list.
* scripts/check-installed-headers.sh: Remove special case for
libio.h and _G_config.h.

With the git checkouts of Hurd components in build-many-glibcs.py
involving running autoreconf, there's a risk that generated files
could be left behind by an old autoreconf run (if an old version of
the sources generates those files in the source directory but a new
version does not).
This patch avoids that by using git clean -dxfq when updating git
checkouts. In this patch, that's conditional on --replace-sources, to
avoid removing any local not-checked-in files someone may have in
their checkout unless the option has been specifically passed that
says it's OK to blow old checkouts away, complete with any local
changes to them.
* scripts/build-many-glibcs.py (Context.git_checkout): Use git
clean -dxfq for git updates when replacing sources.

The disabling of libcilkrts in build-many-glibcs.py has some
peculiarities. It's only for the final GCC build, not the initial
bootstrap one, whereas normally anything disabled for the final build
should be disabled for the bootstrap one as well. And it's only for
Hurd, when it's more natural by analogy with the libsanitizer
disabling to disable this library unconditionally, not only for
targets where it's known to break. This patch cleans up that
disabling accordingly, adding a comment so it's obvious it can be
removed once GCC 7 is too old to build glibc.
* scripts/build-many-glibcs.py (Config.build_gcc): Use
--disable-libcilkrts unconditionally, not just for the final GCC
build for Hurd.

This patch makes build-many-glibcs.py use Linux 4.15. Other glibc

Since it turns out soft-float ColdFire has a different glibc ABI to
hard-float ColdFire, as well as various differences in which glibc
code gets built, this patch adds such a configuration to
build-many-glibcs.py to (hopefully) complete the set of ABIs being
tested. (Note that the build for soft-float ColdFire is currently
broken even with GCC mainline - I have a glibc patch to fix this, but
it needs before-and-after build-many-glibcs.py comparison of stripped
binaries for all configurations before being committed.)
