memcpy_falkor: Fix code style in comments

aarch64: Optimized memcpy for Qualcomm Falkor processor

This is an optimized implementation of the memcpy routine that gives a
significant gain in performance for all sizes of copies on the
Qualcomm Falkor processor.  A detailed rationale of the implementation
is written in a comment in the patch.

This implementation improves time for copies up to 128 bytes by up to
15% and for larger copies by up to 35% in the glibc
microbenchmark. The memcpy-random benchmark sees improvements in all
sizes in the range of 13%-18%.

Here are the full numbers extracted from the glibc microbenchmark
using the commands:

manual: Document getcontext uc_stack value on Linux [BZ #759]

As decribed in BZ#759, Linux getcontext implementation on Linux does
differs from other SysV system about the returned uc_stack.  This is
true not only for i386, but for all the architecture I could actually
check (aarch64, arm, alpha, hppa, m68k, mips, mips64, mips64n32,
powerpc, powerpc64, powerpc64le, s390x, sh, sparc, sparc64, and x86).

And I think we should not change current behavior for some reasons:

1. POSIX 2008 removed this SySV interface for a good reason and changing
   this behavior adds nothing for current portable code.  POSIX 2001
   specification does states that stack should be saved [1] and current
   GLIBC code does in a arch-specific manner (inside the mcontext_t)
   which allows the setcontext to work correctly.

2. Changing this behavior would potentially require compat symbols and
   I see no gain in adding compat symbols for deprecated interfaces.

3. Also, for comment #2 in BZ#759, it is up to kernel do setup the contents
   for ucontext_t and currently it does not provide the stack information
   as well.  Trying to change it is also another fix that does not worth
   the possible gains.

Instead my proposal is to make it clear the current interface may differ
depending of the underlying operational system.

glibc documentation and close this bug as invalid.

Do not use __ptr_t.

sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *.  void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.

Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net).  I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

getaddrinfo: Remove unreachable return statement from gaih_inet

i386: Add <startup.h> [BZ #21913]

On Linux/i386, there are 3 ways to make a system call:

1. call *%gs:SYSINFO_OFFSET.  This requires TLS initialization.
2. call *_dl_sysinfo.  This requires relocation of _dl_sysinfo.
3. int $0x80.  This is slower than #2 and #3, but works everywhere.

When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo.  For
dynamic executables, ld.so initializes TLS.  However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for system calls.

This patch adds <startup.h> which defines _startup_fatal and defaults
it to __libc_fatal.  It replaces __libc_fatal with _startup_fatal in
static executables where it is called before __libc_setup_tls is called.
This header file is included in all files containing functions which are
called before __libc_setup_tls is called.  On Linux/i386, when PIE is
enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and
I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system
calls before __libc_setup_tls is called.

Tested on i686 and x86-64.  Without this patch, all statically-linked
tests will fail on i686 when the compiler defaults to -fPIE.

[BZ #21913]
* csu/libc-tls.c: Include <startup.h> first.
(__libc_setup_tls): Call _startup_fatal instead of __libc_fatal.
* elf/dl-tunables.c: Include <startup.h> first.
* include/libc-symbols.h (BUILD_PIE_DEFAULT): New.
* sysdeps/generic/startup.h: New file.
* sysdeps/unix/sysv/linux/i386/startup.h: Likewise.

(I386_USE_SYSENTER): New.  Defined to 0.

Don't use IFUNC resolver for longjmp or system in libpthread (bug 21041)

Unlike the vfork forwarder and like the fork forwarder as in bug 19861,
there won't be a problem when the compiler does not turn this into a tail
call.

posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)

Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:

$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to ENOTSUP (223)
error: 1 test failures

The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.

Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).

Fix XPG4.2 bits/sigaction.h namespace (bug 21899).

For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.

This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.

For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round.  This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.

For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.

(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)

Tested for x86_64, and with build-many-glibcs.py.

Consistently use uintN_t not u_intN_t everywhere.

This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test.  This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

Tested for x86_64, and with build-many-glibcs.py.

Remove __long_double_t.

sys/cdefs.h has a macro __long_double_t used in two places in glibc.
long double is a standard part of C since C89; there is no need for
such an alias for it.  This patch removes that macro and uses long
double directly everywhere.  As an implementation-namespace,
undocumented symbol, it should not be considered part of the API for
users, and codesearch.debian.net shows no sign of it being used
outside glibc in a way that would break with this patch.

Tested for x86_64.

* misc/sys/cdefs.h (__long_double_t): Remove.
* stdio-common/printf_fp.c (__printf_fp_l): Use long double
instead of __long_double_t,

benchtests: Avoid a display error when running in text terminal

performs a comparison on and that fails if X is not available.  Avoid
the error and ensure that only the graph is generated and saved as a
PNG file.

* benchtests/scripts/compare_strings.py: Avoid display error
when generating graph.

benchtests: Allow selecting baseline for compare_string.py

This patch allows one to provide the function name using an optional
-base option to compare all other functions against.  This is useful
when pitching one implementation of a string function against
alternatives.  In the absence of this option, comparisons are done
against the first ifunc in the list.

* benchtests/scripts/compare_strings.py (main): Add an
optional -base option.
(process_results): New argument base_func.

benchtests: Use TEST_NAME instead of hardcoding memcpy

The hardcoded 'memcpy' name turns up in other derived tests like
mempcpy.

       * benchtests/bench-memcpy.c (test_main): Use TEST_NAME instead of
       hardcoding memcpy.
       * benchtests/bench-memcpy-large.c (test_name): Likewise.

Reimplement min_of_type using __MATH_TG.

This patch reimplements the libm-internal min_of_type macro to use

x86: Remove __memset_zero_constant_len_parameter [BZ #21790]

__memset_zero_constant_len_parameter should be removed by

commit 61062f56304750c367c5c1533351621353c112a7
Author: Ulrich Drepper <drepper@redhat.com>
Date:   Tue Mar 1 00:35:23 2005 +0000

    2005-02-24  Roland McGrath  <roland@redhat.com>

            * debug/Versions (libc: GLIBC_2.4): Remove
            __memset_zero_constant_len_parameter.
            * sysdeps/generic/memset_chk.c: Remove alias and warning.
            * misc/sys/cdefs.h (__warndecl): New macro.
            * debug/warning-nop.c: New file.
            * string/bits/string3.h (memset): Call __warn_memset_zero_len with no
            arguments, instead of calling __memset_zero_constant_len_parameter.
            Use __warndecl for __warn_memset_zero_len.
            * debug/Makefile (routines): Add $(static-only-routines).
            (static-only-routines): New variable.

This patch removes the last emaining pieces of it.  Tested it on i586,
i686 and x86-64.

[BZ #21790]
* sysdeps/i386/i586/memset.S

Fix the return type of the getentropy stub

The return type of the getentropy stub is wrongly defined as ssize_t,
while both the <sys/random.h> header and the Linux implementation
define it as int. This patch fixes that.

Changelog:
* stdlib/getentropy.c (getentropy): Change return type to int.

i686/multiarch: Regenerate ulps

This comes from running “make regen-ulps” on an AMD Opteron 2378 CPU.

Changelog:
* sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Regenerated.

Consistently use uintN_t not u_intN_t in libm.

This patch changes libm code to make consistent use of C99 uintN_t
types instead of sometimes using those and sometimes using the older
nonstandard u_intN_t names.  This makes sense as a cleanup in its own
right, and also facilitates merges to GCC's libquadmath (which gets
the types from stdint.h and so may not have u_intN_t available at
all).

Tested for x86_64, and with build-many-glibcs.py.

tst-tlsopt-powerpc as a shared lib

This makes the __tls_get_addr_opt test run as a shared library, and so
actually test that DTPMOD64/DTPREL64 pairs are processed by ld.so to
support the __tls_get_adfr_opt call stub fast return.  After a
2017-01-24 patch (binutils f0158f4416) ld.bfd no longer emitted
unnecessary dynamic relocations against local thread variables,
instead setting up the __tls_index GOT entries for the call stub fast
return.  This meant tst-tlsopt-powerpc passed but did not check ld.so
relocation support.  After a 2017-07-16 patch (binutils 676ee2b5fa)
ld.bfd no longer set up the __tls_index GOT entries for the call stub
fast return, and tst-tlsopt-powerpc failed.

Compiling mod-tlsopt-powerpc.c with -DSHARED exposed a bug in
powerpc64/tls-macros.h, which defines a __TLS_GET_ADDR macro that
clashes with one defined in dl-tls.h.  The tls-macros.h version is
only used in that file, so delete it and expand.

[hurd]: Add __libc_init_secure stub

csu/libc-start.c now insists on calling __libc_init_secure, while the Hurd

* sysdeps/mach/hurd/enbl-secure.c (__libc_init_secure): Define

Fix tgmath.h for __int128 (bug 21686).

When a tgmath.h macro is passed a double argument and an argument of
type __int128, it generates a call to a long double function (although
the result still gets converted to type double).  __int128 is similar
enough to integer types that it should be handled consistently like
them, so always like double for these macros rather than sometimes
like double and sometimes like long double.  This patch fixes the
logic accordingly and makes gen-tgmath-tests.py generate tests for
__int128.

Tested for x86_64 and x86.

Fix tgmath.h for bit-fields (bug 21685).

The tgmath.h macros produce errors for bit-field arguments, because
they apply sizeof and typeof to the arguments.  This patch fixes them
to use unary + systematically before using sizeof or typeof on
arguments that might be bit-fields (note that __real__ of a bit-field
is still a bit-field for this purpose, since it's an lvalue).
gen-tgmath-tests.py is extended to add tests for this case.

Tested for x86_64.

mutex: Fix robust mutex lock acquire (Bug 21778)

65810f0ef05e8c9e333f17a44e77808b163ca298 fixed a robust mutex bug but
introduced BZ 21778: if the CAS used to try to acquire a lock fails, the
expected value is not updated, which breaks other cases in the loce
acquisition loop.  The fix is to simply update the expected value with
the value returned by the CAS, which ensures that behavior is as if the
first case with the CAS never happened (if the CAS fails).

This is a regression introduced in the last release.

Tested on x86_64, i686, ppc64, ppc64le, s390x, aarch64, armv7hl.

microblaze: Resolve non-relocatable branch in pt-vfork.S (BZ#21779)

The relative branch directly to __libc_vfork results in an relocation
that cannot be resolved. Specifically a R_MICROBLAZE_64_PCREL relocation
is created for this branch, however for MicroBlaze R_MICROBLAZE_64_PCREL
type relocations symbols are not resolved. Additionally due to the
branch being located in the .text section the instruction cannot be
rewritten as the section is not writable, and causes a segfault at
runtime when loading libpthread.

To resolve this issue, ensure the branch is done using PLT. This removes
the need to modify the instruction and trades the R_MICROBLAZE_64_PCREL
for a more common R_MICROBLAZE_JUMP via the PLT.

[BZ #21779]
* sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Branch using PLT.

rwlock: Fix explicit hand-over (bug 21298)

Without this fix, the rwlock can fail to execute the explicit hand-over
in certain cases (e.g., empty critical sections that switch quickly between
read and write phases).  This can then lead to errors in how __wrphase_futex
is accessed, which in turn can lead to deadlocks.

manual: Refactor documentation of CHAR_BIT.

This single-@item @table is better defined with @deftypevr, since the
CHAR_BIT macro has @standards (being declared in a header), and @items
in @tables are not considered annotatable.  Using @deftypevr
automatically includes the macro in the Variable and Constant Macro
Index and ensures its inclusion the Summary of Library Facilities.
@deftypevr is used to record the type of the macro so that it also
appears in the Summary.

tunables: Use direct syscall for access (BZ#21744)

The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno.  It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector.  But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.

This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

H.J. Lu  <hongjiu.lu@intel.com>
Adhemerval Zanella  <adhemerval.zanella@linaro.org>

[BZ #21744]
* elf/dl-tunables.c: Include not-errno.h header.
* include/unistd.h (__access_noerrno): Remove definition.
* sysdeps/unix/sysv/linux/access.c (__access_noerrno): Likewise.
* sysdeps/generic/not-errno.h: New file.
* sysdeps/unix/sysv/linux/not-errno.h: Likewise.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]

__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack.  We should avoid
accessing stack when stack is corrupted.

This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.

[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace.  Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

Remove extra semicolons in struct pthread_mutex (bug 21804)
