4c1d801a59 aarch64: Avoid hidden symbols for memcpy/memmove into static binaries
The __GI_* symbol aliases for __memcpy_generic are unnecessary since
they're never used.  Add them only for libc.so to avoid PLT.  Maybe
some time in future we need to evaluate the relative cost of PLT vs
gains from multiarch memcpy implementations and take a call on whether
to drop this completely.

	* sysdeps/aarch64/multiarch/memcpy_generic.S (__GI_memcpy):
	Define only for libc.so.

478593e637 S390: Fix backtrace in vdso functions.
On s390, GDB fails to show the complete backtrace from within vdso functions.
The macro INTERNAL_VSYSCALL_CALL saves the return address in r14 to r10
before branching to the vdso function. The branch-instruction updates r14
in order to let the vdso function return. Then the original address in r14 is
restored from r10. Unfortunately, there are no cfi-rules and GDB fails.

Furthermore the call of the vdso function does not comply with the s390 ABI
as no stack-frame for the vdso-function is generated.

This patch removes the s390 specific macro INTERNAL_VSYSCALL_CALL
and the common implementation in sysdeps/unix/sysv/linux/sysdep-vdso.h is used.
Then the vdso function is called via function-pointer and GCC generates a
new stack-frame and emits all needed cfi-rules.

The defines CLOBBER_[0-6] are removed as they  were only used in macro
INTERNAL_VSYSCALL_CALL.

The macro INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is not used on s390.
The only user is power. Thus it is removed from s390 sysdep.h.

ChangeLog:

	* sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h
	(INTERNAL_VSYSCALL_CALL, CLOBBER_0, CLOBBER_1, CLOBBER_2,

d17542d235 Use libm_alias_double for remaining powerpc functions.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes the remaining double powerpc functions use
libm_alias_double to define function aliases (with consequent removal
of the need for local compat symbol handling).  Previous cleanups
avoid this patch changing installed stripped shared libraries for any
build-many-glibcs.py configuration (there are still some functions in
this patch for which the order of double and float aliases changes
within an individual source file, but in this case this doesn't result
in changes to the final library).

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

0ddde474db Define powerpc64 lroundl compat symbol only once.
sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c defines the
lroundl compat symbol, version GLIBC_2_1, twice, once based on llround
and once based on __lround.  Those are aliases for each other (llround
weak, __lround strong), but defining it twice does not make sense.
This patch changes it to define the compat symbol once only, matching
how libm_alias_double defines it.

Tested with build-many-glibcs.py for its powerpc64 configurations.

	* sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c
	[LONG_DOUBLE_COMPAT(libm, GLIBC_2_1)] (lroundl): Do not define

0d5ba561c1 Base powerpc logbl compat symbols on __logb not logb.
Some powerpc logb implementations define a compat symbol for logbl
based on logb, whereas libm_alias_double defines such a compat symbol
based on __logb instead.  This difference (logb is weak, __logb isn't)
is enough to result in different installed stripped shared libraries.
The difference in the installed libraries isn't significant, but first
changing the compat_symbol calls helps make it possible to validate a
subsequent change to use libm_alias_double by comparison of libraries,
so this patch does such a preliminary change.

Tested with build-many-glibcs.py for all its hard-float powerpc
configurations.

51ea3b2042 Ues libm_alias_double for various powerpc functions.
Continuing the preparation for additional _FloatN / _FloatNx function

some functions where such changes could result in differences in
installed stripped shared libraries because of changes to the exact

ec2cf3f444 Use libm_alias_double for powerpc fabs, fma.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes powerpc fabs and fma use libm_alias_double
to define function aliases.  This brings in automatic symbol
versioning compat handling, so the powerpc32 and powerpc64 wrappers
that added such handling to the generic sysdeps/powerpc/fpu versions
are removed as no longer required (there are no sysdeps directory
ordering issues that would necessitate keeping trivial wrappers
there).

e53df1dee8 Rework m68k libm functions to use declare_mgen_alias.
Many m68k libm functions use their own system to share code between
different types and functions, involving defining macros before
including code for another function (for example, s_atan.c also acts
as a template that can define other functions).

Thes files serving as templates generate function aliases directly
with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c.  To be
prepared to generate _Float32, _Float64 and _Float32x function
aliases, this needs changing so that the libm_alias_* macros get used
instead.  As the macro to use varies depending on the type, that would
mean additional macros to define in several different places to get
the appropriate alias-generation macro used in each case.

Rather than adding to the m68k-specific mechanisms, this patch
converts the functions in question to use something closer to the
math/ type-generic template mechanism.  After this patch, these
functions have m68k-specific templates such as s_atan_template.c, but
those templates use all the same macros as in the math/ templates,
such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias.  There is no
automatic generation of the files such as s_atan.c that include the
appropriate math-type-macros-*.h header and the template file (the
existing automatic generation logic is only applicable for the fixed
set of templates listed in math/ - and sysdeps sources always override
files generated that way), so those files are still checked in, but
they are all the obvious two-line files (with one additional
definition in the case of the expm1 implementations), rather than
making e.g. s_atan.c special.

Functions are only converted where they should have aliases for
_FloatN / _FloatNx types.  Those m68k functions that do not generate
public names (those that only generate __ieee754_*, with wrappers
generating the public names, and classification functions that only
exist once per format not once per type so don't get aliases) are
unchanged.  However, log1p (public names generated by wrapper) and
significand (not provided for new types so no new aliases needed)
needed changing because they previously included the atan
implementations.  Now, s_significand.c is the main implementation for
functions with that prototype and using the old implementation
approach, while log1p includes it in place of atan.

Any further cleanups in this area (which preserve the proper set of
functions getting aliases defined by libm_alias_float and
libm_alias_double) are of course welcome, just not needed for the
goals of this patch.

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

1faaf7035c plural.c: improve reproducibility
There is a subtle non-determinism when building glibc.
This depends on whether the glibc is built using the distibuted
file intl/plural.c or built using the generated file intl/plural.c.
These two files (intl/plural.c generated vs. distributed) are slightly
different, hence we may end up with slightly different libraries.

Originally, having "bison" installed was optional. So if "bison" was
not present, we always built libraries with the distributed plural.c.
If bison was installed, we *** may have *** replaced the distributed
file plural.c with a new plural.c generated from plural.y. if the
timestamps triggered this rule:

plural.c plural.y
	$(BISON) $(BISONFLAGS) $@ $^

Given that timestamps are not preserved in GIT repositories, the above
rule is not reliable without explicitly touching plural.c or plural.y.
In other words, the rule may or may not have fired.

In summary: there are two distinct sources of non-determinism:

1. Having "bison" installed or not
2. Having "bison" installed but timestamps poorly defined.

This patch fixes this by requiring "bison" being installed
and by always generating intl/plural.c from intl/plural.y.
(This is achieved by simply removing checked-in intl/plural.c)

bd6ea9edd1 Use libm_alias macros in m68k llrint functions.
Most m68k libm functions share code via sources for one function
including those for another function or type, in a way that will
require significant changes to create function aliases in a way
friendly to adding _FloatN / _FloatNx aliases.

The llrint function implementations, however, use a conventional
separate implementation for each floating-point type.  Thus preparing
them for _FloatN / _FloatNx aliases is just a matter of changing them
to include the appropriate headers and use the appropriate macros,
which this patch does.  The llrintl changes aren't strictly required,
since m68k long double does not meet the criteria for a _FloatN /
_FloatNx type, but are included anyway to keep consistency between the
implementations for the three types.

Tested with build-many-glibcs.py that installed stripped shared
libraries for m68k-linux-gnu are unchanged by the patch.

f33632ccd1 x86: Make a space in jmpbuf for shadow stack pointer
To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement
Technology (CET) in setjmp/longjmp, we need to save shadow stack
pointer in jmp_buf.  The __saved_mask field in jmp_buf has type
of __sigset_t.  On Linux, __sigset_t is defined as

 #define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int)))
typedef struct
{
  unsigned long int __val[_SIGSET_NWORDS];
} __sigset_t;

which is much bigger than expected by the __sigprocmask system call,
which has

typedef struct {
        unsigned long sig[_NSIG_WORDS];
} sigset_t;

For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf
to add paddings for shadow stack pointer.  As long as the new __sigset_t
is not smaller than sigset_t expected by the __sigprocmask system call,
it should work correctly.

This patch adds an internal header file, <setjmpP.h>, to define
__jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a
space to store shadow stack pointer.  It verifies __jmp_buf_sigset_t has
the suitable size for the __sigprocmask system call.   A run-time test,
tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t
is sufficient.  If its size is too small, the test fails with

rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc
0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address)
rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc
0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address)
rt_sigprocmask(SIG_SETMASK, NULL, 0x7fa8aa28effc, 8) = -1 EFAULT (Bad address)
exit_group(1)                           = ?

34697694e8 Fix integer overflow in malloc when tcache is enabled [BZ #22375]
When the per-thread cache is enabled, __libc_malloc uses request2size (which
does not perform an overflow check) to calculate the chunk size from the
requested allocation size. This leads to an integer overflow causing malloc
to incorrectly return the last successfully allocated block when called with
a very large size argument (close to SIZE_MAX).

This commit uses checked_request2size instead, removing the overflow.

18305fba55 Remove SPARC lllrint aliases.
The sparc32/sparcv9/fpu/multiarch implementations of llrint / llrintf
have aliases lllrint / lllrintf.  No such function is exported from or
used in libm and these aliases should not be there; I expect they
arose accidentally in the course of converting a 64-bit implementation
(where lrint and llrint can be aliases) to a 32-bit llrint
implementation.  This patch removes those spurious aliases.

cf4ebc27fe Fix missing sparcv9 --disable-multi-arch fabsl compat symbol (bug 22229).
The --disable-multi-arch case of sparcv9 libm is missing a fabsl
compat symbol for when long double had the same ABI as double.  This
patch adds the missing compat symbol to this implementation.  As my
fix for other instances of this missing compat symbol postdates the
last release, I'm considering this as being part of bug 22229 that was
missing from my previous fix rather than as a separate issue, and so
as not needing a new bug report in Bugzilla.

Tested (compilation only) with build-many-glibcs.py for
sparcv9-linux-gnu --disable-multi-arch.

While working on SPARC changes to use libm_alias_* I noticed that the

support for fabsl.  This clearly shows inadequate test coverage, so
this patch adds SPARC --disable-multi-arch builds to
build-many-glibcs.py (the 32-bit one fails testing until that bug is
fixed, the 64-bit one passes testing).
