This patch removes the HP_TIMING_BITS usage for fast random bits and replace
with clock_gettime (CLOCK_MONOTONIC). It has unspecified starting time and
nano-second accuracy, so its randomness is significantly better than
gettimeofday.
Althoug it should incur in more overhead (specially for architecture that
support hp-timing), the symbol is also common implemented as a vDSO.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu. I also
checked on a i686-gnu build.

With clock_getres, clock_gettime, and clock_settime refactor to remove the
generic CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID support through
hp-timing, there is no usage of internal __get_clockfreq. This patch removes
both generic and Linux implementation..

The Linux 3.2 clock_getres kernel code (kernel/posix-cpu-timers.c)
issued for clock_getres CLOCK_PROCESS_CPUTIME_ID (process_cpu_clock_getres)
and CLOCK_THREAD_CPUTIME_ID (thread_cpu_clock_getres) call
posix_cpu_clock_getres. And it fails on check_clock only if an invalid
clock is used (not the case) or if we pass an invalid the pid/tid in
29 msb of clock_id (not the case either).
This patch assumes that clock_getres syscall always support
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID, so there is no need
to fallback to hp-timing support for _SC_MONOTONIC_CLOCK neither to issue
the syscall to certify the clock_id is supported bt the kernel. This
allows simplify the sysconf support to always use the syscall.
it also removes ia64 itc drift check and assume kernel handles it correctly.

This patch removes CLOCK_THREAD_CPUTIME_ID and CLOCK_PROCESS_CPUTIME_ID support
from clock_gettime and clock_settime generic implementation. For Linux, kernel
already provides supports through the syscall and Hurd HTL lacks
__pthread_clock_gettime and __pthread_clock_settime internal implementation.
As described in clock_gettime man-page [1] on 'Historical note for SMP
system', implementing CLOCK_{THREAD,PROCESS}_CPUTIME_ID with timer registers
is error-prone and susceptible to timing and accurary issues that the libc
can not deal without kernel support.
This allows removes unused code which, however, still incur in some runtime
overhead in thread creation (the struct pthread cpuclock_offset
initialization).
If hurd eventually wants to support them it should either either implement as
a kernel facility (or something related due its architecture) or in system
specific implementation.

Two cases of "int * 1.4" may result in imprecise results, which
in at least one case resulted in i686 and x86-64 producing
different locale files. This replaced that floating point multiply
with integer operations. While the hash table margin is increased
from 40% to 50%, testing shows only 2% increase in overall size
of the locale archive.

This patch updates sysdeps/unix/sysv/linux/syscall-names.list for
Linux 5.0. Based on testing with build-many-glibcs.py, the only new
entry needed is for old_getpagesize (a newly added __NR_* name for an
old syscall on ia64). (Because 5.0 changes how syscall tables are
handled in the kernel, checking diffs wasn't a useful way of looking
for new syscalls in 5.0 as most of the syscall tables were moved to
the new representation without actually adding any syscalls to them.)

Fixes bug 24216. This patch adds security checks for bk and bk_nextsize pointers

The stub implementations are turned into compat symbols.
Linux actually has two reserved system call numbers (for getpmsg
and putpmsg), but these system calls have never been implemented,
and there are no plans to implement them, so this patch replaces
the wrappers with the generic stubs.
According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>,
the presence of the XSI STREAMS declarations is a minor portability
hazard because they are not actually implemented.
This commit does not change the TIRPC support code in
sunrpc/rpc_svcout.c. It uses additional XTI functionality and
therefore never worked with glibc.

This patch makes build-many-glibcs.py use Linux 5.0 in place of 4.20

The test for obsolete typedefs in installed headers was implemented
using grep, and could therefore get false positives on e.g. “ulong”
in a comment. It was also scanning all of the headers included by
our headers, and therefore testing headers we don’t control, e.g.
Linux kernel headers.
This patch splits the obsolete-typedef test from
scripts/check-installed-headers.sh to a separate program,
scripts/check-obsolete-constructs.py. Being implemented in Python,
it is feasible to make it tokenize C accurately enough to avoid false
positives on the contents of comments and strings. It also only
examines $(headers) in each subdirectory--all the headers we install,
but not any external dependencies of those headers. Headers whose
installed name starts with finclude/ are ignored, on the assumption
that they contain Fortran.
It is also feasible to make the new test understand the difference
between _defining_ the obsolete typedefs and _using_ the obsolete
typedefs, which means posix/{bits,sys}/types.h no longer need to be
exempted. This uncovered an actual bug in bits/types.h: __quad_t and
__u_quad_t were being used to define __S64_TYPE, __U64_TYPE,
__SQUAD_TYPE and __UQUAD_TYPE. These are changed to __int64_t and
__uint64_t respectively. This is a safe change, despite the comments
in bits/types.h claiming a difference between __quad_t and __int64_t,
because those comments are incorrect. In all current ABIs, both
__quad_t and __int64_t are ‘long’ when ‘long’ is a 64-bit type, and
‘long long’ when ‘long’ is a 32-bit type, and similarly for __u_quad_t
and __uint64_t. (Changing the types to be what the comments say they
are would be an ABI break, as it affects C++ name mangling.) This
patch includes a minimal change to make the comments not completely
wrong.
sys/types.h was defining the legacy BSD u_intN_t typedefs using a
construct that was not necessarily consistent with how the C99 uintN_t
typedefs are defined, and is also too complicated for the new script to
understand (it lexes C relatively accurately, but it does not attempt
to expand preprocessor macros, nor does it do any actual parsing).
This patch cuts all of that out and uses bits/types.h's __uintN_t typedefs
to define u_intN_t instead. This is verified to not change the ABI on
any supported architecture, via the c++-types test, which means u_intN_t
and uintN_t were, in fact, consistent on all supported architectures.

The check for "/finclude/" fails with the actual location of
Fortran headers because they are now stored in the "finclude"
subdirectory of the top-level include directory, so a relative path
does not contain a slash '/' before the "finclude" string.

This patch assumes realtime clock support for nptl and thus removes
all the associated code.
For __pthread_mutex_timedlock the fallback usage for the case where
lll_futex_timed_wait_bitset it not set define is also removed. The
generic lowlevellock-futex.h always define it, so for NPTL code the
check always yield true.
Checked on x86_64-linux-gnu and i686-linux-gnu.
* nptl/nptl-init.c (__have_futex_clock_realtime,
__have_futex_clock_realtime): Remove definition.
(__pthread_initialize_minimal_internal): Remove FUTEX_CLOCK_REALTIME
check test for !__ASSUME_FUTEX_CLOCK_REALTIME.
* nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock): Assume
__ASSUME_FUTEX_CLOCK_REALTIME support.

wcsmbs: optimize wcscat
powerpc64 and powerpc64le builds fail when configured with
--disable-multi-arch and --with-cpu=power6 (or newer), due to an
undefined reference to __GI___wcscpy. This patch fixes this on
sysdeps/powerpc/powerpc64/power6/wcscpy.c, which is only used when
multi-arch is disabled.
This patch does nothing for the failures on 32-bits powerpc builds,
because the file is under the powerpc64 subdirectory, however, powerpc
builds were already failing with --disable-multi-arch, with multiple
error messages, even before the aforementioned commit.
Tested for powerpc, powerpc64, and powerpc64le with multi-arch enabled
(all pass) and disabled (powerpc still fails as explained above).

Set the default function alignment to 16 bytes in order to
get rid of some unwanted performance effects.
Please see also GCC commit "S/390: Set default function
alignment to 16." (Subversion revision 262817)
ChangeLog:
* sysdeps/s390/s390-64/sysdep.h(ENTRY): Use alignment of 16byte.

The offset in era-string format for Taisho gan-nen (1912) is currently
defined as 2, but it should be 1. So fix it. "Gan-nen" means the 1st
(origin) year, Taisho started on July 30, 1912.

* localedata/locales/ja_JP (LC_TIME): Change the offset for Taisho
gan-nen from 2 to 1. Problem reported by Morimitsu, Junji.

This patch adds test cases for the compatibility versions of the
functions: err, errx, verr, verrx, warn, warnx, vwarn, vwarnx (from
err.h), error, and error_at_line (from error.h), when long double has
the same format as double (-mlong-double-64).
Tested for powerpc, powerpc64 and powerpc64le.
|
|
On platforms where long double may have the same format as double
(-mlong-double-64), error and error_at_line do not take that into
account and might produce wrong output if a long double conversion is
requested by the format string ('%Lf'). This patch adds compatibility
functions for this situation and redirects calls via header magic.
Tested for powerpc, powerpc64 and powerpc64le.
|
|
When support for long double format with 128-bits (-mlong-double-128)
was added for platforms where long double had the same format as double,
such as powerpc, compatibility versions for the functions listed in the
commit title were missed. Since the older format of long double can
still be used (with -mlong-double-64), using these functions with a
format string that requests the printing of long double variables will
produce wrong outputs.
This patch adds the missing compatibility functions and header magic to
redirect calls to them when -mlong-double-64 is in use.
Tested for powerpc, powerpc64 and powerpc64le.
|
|
The test case tst-ldbl-argp checks that the conversion specifier '%Lf'
correctly prints long double values with the default long double format
for a platform. This patch reuses the test case for long double with
the same format as double (-mlong-double-64).
Tested for powerpc, powerpc64 and powerpc64le.
|
|
The functions argp_error and argp_failure are missing support for
printing long double values when long double has the same format as
double. This patch adds the new functions __nldbl_argp_error and
__nldbl_argp_failure, as well as header magic to redirect calls to them
when -mlong-double-64 is in use.
Tested for powerpc, powerpc64 and powerpc64le.

It is possible that the link editor injects an allocated ABI tag note
before the artificial, allocated large note in the test. Note parsing
in open_verify stops when the first ABI tag note is encountered, so if
the ABI tag note comes first, the problematic code is not actually
exercised.
Also tweak the artificial note so that it is a syntactically valid
4-byte aligned note, in case the link editor tries to parse notes and
process them.
Improves the testing part of commit 0065aaaaae51cd60210ec3a7e13.
