Paul Clarke f4b2aea6e1 New generic cosf
The same logic used in s_cosf.S version for x86 and powerpc
is used to create a generic s_cosf.c, so there is no performance
improvement in x86_64 and powerpc64.

	* sysdeps/ieee754/flt-32/s_cosf.c: New implementation.

Adhemerval Zanella c9cd7b0ce5 powerpc: POWER8 memcpy optimization for cached memory
On POWER8, unaligned memory accesses to cached memory has little impact
on performance as opposed to its ancestors.

It is disabled by default and will only be available when the tunable
glibc.tune.cached_memopt is set to 1.

Stefan Liebler dee943668f S390: Add CFI rule in _dl_runtime_resolve[_vx] for unwinding.
In _dl_runtime_resolve[_vx], unwinding fails after the new stack frame
is created as there is no CFI rule for r15. This is also observeable in
GDB: Backtrace stopped: previous frame inner to this frame (corrupt stack?)

Therefore this patch is now storing r15 on stack and is using cfi_offset rule.
The stmg/lmg instruction is used to store/load r14 and r15 with one instruction.
On 64bit, the offsets of the fprs have moved to store r15 directly after r14.
On 31bit, the r14/r15 is now stored between the other gprs and fprs as the space
wasn't used.

ChangeLog:

	* sysdeps/s390/s390-64/dl-trampoline.h (_dl_runtime_resolve):
	Store r15 on stack and add cfi rule.
	* sysdeps/s390/s390-32/dl-trampoline.h (_dl_runtime_resolve):
	Likewise.

Joseph Myers d15e83c5f5 Fix ctanh (0 + i NaN), ctanh (0 + i Inf) (bug 22568, DR#471).
As per C11 DR#471, ctanh (0 + i NaN) and ctanh (0 + i Inf) should
return 0 + i NaN (with "invalid" exception in the second case but not
the first), not NaN + i NaN.  This has corresponding implications for
ctan since its special cases are defined by ctan (z) = -i ctanh (iz).
This patch implements these cases for ctanh and ctan, updating
tests accordingly.

Joseph Myers 1f9055ce04 Add _Float32 function aliases.
This patch concludes filling out TS 18661-3 support for different
types by adding *f32 function aliases of float functions to support
_Float32.  As with _Float64 and _Float32x, this is supported for all
glibc configurations.  As with the previous such patches there are
some x86 ulps updates because of inline functions present for float
but not for _Float32.  The patch also has the usual
bits/floatn-common.h update, symbol versions, ABI baselines updates,
test enablement and documentation.

As per C11 DR#471 (adjusted resolution accepted for C17), cacosh (0 +
iNaN) should return NaN +/- i pi/2, not NaN + iNaN.

This patch fixes the code accordingly.  The test has hardcoded the

comment), since the unspecified sign for a result other than 0 or
infinity isn't currently supported by the test infrastructure.

Joseph Myers 1dbe6f64ab Don't make local variables static in ldbl-96 j1l.
The ldbl-96 implementation of j1l has some function-local variables
that are declared static for no apparent reason (this dates back to
the first addition of that file).

Any vaguely recent compiler, probably including any that are supported
for building glibc, optimizes away the "static" here, as the values of
the variables on entry to the function are dead.  So there is not
actually a user-visible bug here at present (but with any compilers
that didn't optimize away the static at all, possibly building with
less or no optimization, so that the function stored intermediate
values to and then loaded them from the variables, there would have
been a thread-safety issue).  But the "static" clearly doesn't belong
there and might potentially make things unsafe were compilation
without optimization to be supported in future, so this patch removes
it.

Tested for x86_64.

I noticed that an x86_64 build of libm unexpectedly contained more

did.  The problem is non-const arrays in the ldbl-128 j0l and j1l
implementations; this patch makes those arrays, and the corresponding
ldbl-128ibm ones, const.

Tested for x86_64, and tested compilation for powerpc with

Joseph Myers 0d93b7fd7c Add _Float64, _Float32x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64 and
*f32x function aliases, supporting _Float64 and _Float32x, as aliases
for double functions.  These types are supported for all glibc
configurations.  The API corresponds exactly to that for _Float128 and
_Float64x.  _Float32 aliases to float functions remain to be added in
subsequent patches to complete this process (then there are a few
miscellaneous functions in TS 18661-3 to implement that aren't simply
versions of existing functions for new types).

The patch enables the feature in bits/floatn-common.h, adds symbol
versions and documentation with updates to ABI baselines, and arranges
for the libm functions for the new types to be tested.  As with the
_Float64x changes there are some x86 ulps updates because of header
inlines not used for the new types (and one other change to the
non-multiarch libm-test-ulps, which I suppose comes from using a
different compiler version / configuration from when it was last
regenerated).

Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

	* bits/floatn-common.h (__HAVE_FLOAT64): Define to 1.
	(__HAVE_FLOAT32X): Likewise.
	* manual/math.texi (Mathematics): Document support for _Float64

Joseph Myers f778723496 Use long double not double for _Float64 with old GCC if values the same.
If double, long double and _Float64 all have the same set of values,
TS 18661-3 requires the usual arithmetic conversions on long double
and _Float64 to produce _Float64.  For this to be the case when
building with a compiler without a distinct _Float64 type, _Float64
must be a typedef for long double, not for double.  (_Float32x,
however, must be double in such a case, not long double, because the
usual arithmetic conversions on _Float32x and double must produce
double.)

This patch adjusts the fallback definition of _Float64 and associated
macros accordingly in that case, to fix the build of test-tgmath3 with
GCC 6 for such a configuration.  Tested in conjunction with _Float64
changes with build-many-glibcs.py for arm-linux-gnueabi, to make sure
the issue with test-tgmath3 is fixed.  Also tested for x86_64.

Rogerio Alves 07ed18d26a Add elision tunables
This patch adds several new tunables to control the behavior of
elision on supported platforms[1].   Since elision now depends
on tunables, we should always *compile* with elision enabled,
and leave the code disabled, but available for runtime
selection.  This gives us *much* better compile-time testing of
the existing code to avoid bit-rot[2].

Tested on ppc, ppc64, ppc64le, s390x and x86_64.

Florian Weimer 446d22e91d Linux: Implement interfaces for memory protection keys
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.

Mike FABIAN 1f6d91f328 hr_HR locale: Don’t use single code points for the digraphs in LC_TIME
[BZ #10580]
	* localedata/locales/hr_HR (LC_TIME): Use two letters for the
	digraphs in the month and day names. Using single code points for
	digraphs is deprecated.  While there are dedicated Unicode
	codepoints, for the digraphs, these are included for backwards
	compatibility and modern texts use a sequence of Basic Latin
	characters. See: https://www.unicode.org/faq/ligature_digraph.html
	This makes the month and day names agree exactly with CLDR now,
	CLDR does not use the single code points for the digraphs either.

Joseph Myers 73895b499b Use __floor not floor in sinf.
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.

Siddhesh Poyarekar 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.

Stefan Liebler 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,
	 CLOBBER_3, CLOBBER_4, CLOBBER_5, CLOBBER_6,
	INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK): Remove.

Joseph Myers 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.
