Avoid an issue in gcc where some of the vector (aka SIMD) ops will
sometimes end up getting wrongly optimized out. We use these
instructions in many of the string implementations. If/when we
have an upstreamed fix for this problem in gcc we can conditionalize
the use of the extended assembly workaround in glibc.
This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect,
and x86-64 implementations of pkey_get and pkey_set, which abstract over
the PKRU CPU register and hide the actual number of memory protection
keys supported by the CPU. pkey_mprotect with a -1 key is implemented
using mprotect, so it will work even if the kernel does not support the
pkey_mprotect system call.
The system call wrapers use unsigned int instead of unsigned long for
parameters, so that no special treatment for x32 is needed. The flags
argument is currently unused, and the access rights bit mask is limited
to two bits by the current PKRU register layout anyway.

The new sinf implementation introduced localplt failures for all
platforms where the compiler did not inline the calls to floor
(converted to trunc by machine-independent optimizations). This patch
changes the calls to use __floor as normal in libm.
We can't use the public function names floor / floorf / floorl /
floorf128 in libm code in the absence of appropriate asms to redirect
floor/trunc calls, if not inlined, to use the internal names instead
(while avoiding breaking code building the floor functions themselves)
- while having such asms and then calling the public functions
unconditionally would be desirable for optimization (few architectures
have __floor inlines in math_private.h, and once the built-in function
is used you don't need them), using __floor is the minimum safe fix
for the present test regressions.
Tested with build-many-glibcs.py that this fixes the localplt test
failure for arm-linux-gnueabi.
* sysdeps/ieee754/flt-32/s_sinf.c (SINF_FUNC): Use __floor instead
of floor.
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.
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.

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.

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
compat symbol based on llround.
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.

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).

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.

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.

Some m68k libm functions have their own templates replacing the
generic math/ ones but using the type-generic template machinery.

preparation for additional _FloatN / _FloatNx function aliases, this

instead.

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)

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.

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.
