2cbec36566 SPARC: fix nearbyint on sNaN input
nearbyint and nearbyintf should not trigger inexact exceptions, but
should still trigger an invalid exception for a sNaN input.

The SPARC specific implementations of these functions save the FSR at
the beginning of the function and restore it at the end to not trigger
an inexact exception. This however doesn't work for an sNaN input which
need to trigger an invalid exception. Fix that by adding a fcmp
instruction using the input value before saving FSR, so that an invalid
exception is triggered for a sNaN input.

This fixes the math/test-nearbyint-except test on SPARC.

16396c41de Add _STRING_INLINE_unaligned and string_private.h
As discussed in

https://sourceware.org/ml/libc-alpha/2015-10/msg00403.html

the setting of _STRING_ARCH_unaligned currently controls the external
GLIBC ABI as well as selecting the use of unaligned accesses withing
GLIBC.

Since _STRING_ARCH_unaligned was recently changed for AArch64, this
would potentially break the ABI in GLIBC 2.23, so split the uses and add
_STRING_INLINE_unaligned to select the string ABI. This setting must be
fixed for each target, while _STRING_ARCH_unaligned may be changed from
release to release.  _STRING_ARCH_unaligned is used unconditionally in
glibc.  But <bits/string.h>, which defines _STRING_ARCH_unaligned, isn't
included with -Os.  Since _STRING_ARCH_unaligned is internal to glibc and
may change between glibc releases, it should be made private to glibc.
_STRING_ARCH_unaligned should defined in the new string_private.h heade
file which is included unconditionally from internal <string.h> for glibc
build.

b02840bacd New pthread_barrier algorithm to fulfill barrier destruction requirements.
The previous barrier implementation did not fulfill the POSIX requirements
for when a barrier can be destroyed.  Specifically, it was possible that
threads that haven't noticed yet that their round is complete still access
the barrier's memory, and that those accesses can happen after the barrier
has been legally destroyed.
The new algorithm does not have this issue, and it avoids using a lock
internally.

f63f2bfdfa Convert 69 more function definitions to prototype style (line wrap cases).
This automatically-generated patch converts 69 function definitions in
glibc from old-style K&R to prototype-style.

This patch, covering both sysdeps and non-sysdeps files, deals with
cases where the prototype needed to be wrapped over more than one
line.  Otherwise, exclusions and caveats are as for

shared libraries are unchanged by the patch).

bd2260a206 Convert 231 sysdeps function definitions to prototype style.
This mostly automatically-generated patch converts 231 sysdeps
function definitions in glibc from old-style K&R to prototype-style.

For __aio_sigqueue and __gai_sigqueue I had to add internal_function
to the definitions as noted by Florian in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00595.html> to keep
the functions compiling on x86 after conversion to prototype
definitions.  Otherwise, the patch is automatically generated with all
the same exclusions and caveats as in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> except
that it's a patch for sysdeps files.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).  Also tested for arm,
mips64 and powerpc32 that installed stripped shared libraries are
unchanged by the patch.

da2f4f2dd5 Make scalbn set errno (bug 6803).
As noted in bug 6803, scalbn fails to set errno on overflow and
underflow.  This patch fixes this by making scalbn an alias of ldexp,
which has exactly the same semantics (for floating-point types with
radix 2) and already has wrappers that deal with setting errno,
instead of an alias of the internal __scalbn (which ldexp calls).

Notes:

* Where compat symbols were defined for scalbn functions, I didn't
  change what they point to (to keep the patch minimal), so such
  compat symbols continue to go directly to the non-errno-setting
  functions.

* Mike, I didn't do anything with the IA64 versions of these
  functions, where I think both the ldexp and scalbn functions already
  deal with setting errno.  As a cleanup (not needed to fix this bug)
  however you might want to make those functions into aliases for
  IA64; there is no need for them to be separate function
  implementations at all.

* This concludes the fix for bug 6803 since the scalb and scalbln
  cases of that bug were fixed some time ago.

Tested for x86_64, x86, mips64 and powerpc.

de071d199a Move bits/atomic.h to atomic-machine.h (bug 14912).
It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/atomic.h to atomic-machine.h to follow that
convention.

This is the only change in this series that needs to change the
filename rather than simply removing a directory level (because both
atomic.h and bits/atomic.h exist at present).

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

a2f0363f81 Add and use new glibc-internal futex API.
This adds new functions for futex operations, starting with wait,
abstimed_wait, reltimed_wait, wake.  They add documentation and error
checking according to the current draft of the Linux kernel futex manpage.

Waiting with absolute or relative timeouts is split into separate functions.
This allows for removing a few cases of code duplication in pthreads code,
which uses absolute timeouts; also, it allows us to put platform-specific
code to go from an absolute to a relative timeout into the platform-specific
futex abstractions..

Futex operations that can be canceled are also split out into separate
functions suffixed by "_cancelable".

There are separate versions for both Linux and NaCl; while they currently
differ only slightly, my expectation is that the separate versions of
lowlevellock-futex.h will eventually be merged into futex-internal.h
when we get to move the lll_ functions over to the new futex API.

4eb984d3ab Clean up BUSY_WAIT_NOP and atomic_delay.
This patch combines BUSY_WAIT_NOP and atomic_delay into a new
atomic_spin_nop function and adjusts all clients.  The new function is
put into atomic.h because what is best done in a spin loop is
architecture-specific, and atomics must be used for spinning.  The
function name is meant to tell users that this has no effect on
synchronization semantics but is a performance aid for spinning.

90dd591393 Fix mq_notify pthread_barrier_* namespace (bug 18544).
mq_notify (present in POSIX by 1996) brings in references to
pthread_barrier_init and pthread_barrier_wait (new in the 2001 edition
of POSIX).  This patch fixes this by making those functions into weak
aliases of __pthread_barrier_*, exporting the __pthread_barrier_*
names at version GLIBC_PRIVATE and using them in mq_notify.

Tested for x86_64 and x86 (testsuite, and comparison of installed
stripped shared libraries).  Changes in addresses from dynamic symbol
table / PLT changes render most comparisons not particularly useful,
but when the addresses of subsequent code don't change there's no sign
of unexpected changes there.  This patch does not remove any
linknamespace XFAILs because of other namespace issues remaining with
mqueue.h functions.

d051b143f7 Fix sem_* tdelete, tfind, tsearch, twalk namespace (bug 18536).
The sem_* functions bring in references to tdelete, tfind, tsearch and
twalk.  But the t* functions are XSI-shaded, while sem_* aren't.  This
patch fixes this by using __t* instead, exporting those functions from
libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and
using libc_hidden_* for the benefit of calls within libc.

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed stripped shared libraries).  libpthread gets changes from
PLT reordering; addresses in libc change because of PLT / dynamic
symbol table changes.

0747f81811 Fix libm feraiseexcept namespace (bug 17723).
Various C90 and UNIX98 libm functions call feraiseexcept, which is not
in those standards.  This causes linknamespace test failures - except
on x86 / x86_64, where feraiseexcept is inline (for the relevant
constant arguments) in bits/fenv.h.

This patch fixes this by making those functions call __feraiseexcept
instead.  All changes are applied to all architectures rather than
considering the possibility that some might not be needed in some
cases (e.g. x86) as it seems most maintainable to keep architectures
consistent.

Where __feraiseexcept does not exist, it is added, with feraiseexcept
made a weak alias; where it is a strong alias, it is made weak.
libm_hidden_def / libm_hidden_proto are used with __feraiseexcept
(this might in some cases improve code generation for existing calls
to __feraiseexcept in some code on some architectures).  Where there
are dummy feraiseexcept macros (on architectures without
floating-point exceptions support, to avoid compile errors from
references to undefined FE_* macros), corresponding dummy
__feraiseexcept macros are added.  And on x86, to ensure
__feraiseexcept calls still get inlined, the inline function in
bits/fenv.h is refactored so that most of it can be reused in an
inline __feraiseexcept in a separate include/bits/fenv.h.

Calls are changed in C90/UNIX98 functions, but generally not in
functions missing from those standards.  They are also changed in
libc_fe* functions (on the basis that those might be used in any libm
function), and in feupdateenv (on the same basis - may be used, via
default libc_*, in any libm function - of course feupdateenv will need
changing to __feupdateenv in a subsequent patch to make that fully
namespace-clean).

No __feraiseexcept is added corresponding to the feraiseexcept in
powerpc bits/fenvinline.h, because that macro definition is
conditional on !defined __NO_MATH_INLINES, and glibc libm is built
with -D__NO_MATH_INLINES, so changing internal calls to use
__feraiseexcept should make no difference.

Tested for x86_64 (testsuite; the only change in disassembly of
installed shared libraries is a slight code reordering in clog10, of
no apparent significance).  Also tested for MIPS, where (in the
configuration tested) it eliminates math.h linknamespace failures for
n32 and n64 (some for o32 remain because of other issues).

USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the
__atomic* builtins (aarch64, mips partially) or if this has been

c5684fdb2b Don't use INTDEF/INTUSE with _dl_init (bug 14132).
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch eliminates its use for _dl_init.  Since _dl_init was already
declared with hidden visibility, creating a second hidden alias for it
was completely pointless, so this patch replaces all uses of
_dl_init_internal with plain _dl_init instead of using hidden_proto /
hidden_def (which are only needed when you want a hidden alias for a
non-hidden symbol; it's quite possible there are cases where they are
used but don't need to be because the symbol in question is not part
of the public ABI and is only used within a single library, so using
attributes_hidden instead would suffice).

Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

73e28d9c88 soft-fp: Refactor exception handling for comparisons.
This patch refactors how soft-fp comparisons handle setting exceptions
for NaN operands, so that exceptions are set through the FP_CMP macros
rather than directly in the C files calling them.

The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when
exceptions should be set, 0 for no exception setting (I'm not sure
this is actually needed - at least it's not needed for IEEE operations
in glibc / libgcc, but might be relevant in some cases for kernel
use), 1 for exceptions only for signaling NaNs and 2 for exceptions
for all NaNs.  This argument is handled through _FP_CMP_CHECK_NAN,
newly called by the _FP_CMP* macros when a NaN is encountered.  Calls
to these macros are updated, which eliminates all the existing
checking and exception setting in soft-fp *.c files in glibc.

Tested for powerpc-nofpu.  (The __unord* functions have no code
changes; the __eq* / __ge* / __le* functions get slightly larger, but
I don't think that's significant.)

2d6a47ba4c soft-fp: Remove FP_CLEAR_EXCEPTIONS.
As noted in
<https://sourceware.org/ml/libc-alpha/2013-10/msg00516.html>, the
soft-fp macro FP_CLEAR_EXCEPTIONS should not be necessary, as soft-fp
code should never set an exception and later clear it.

In fact, all four uses in glibc (for SPARC) are indeed unnecessary:
they appear in files that convert 32-bit or 64-bit integers to IEEE
binary128, an operation that can never raise any exceptions.  If this
was intended to enable the compiler to optimize away any FP_FROM_INT
code testing for exceptional cases, we now have a better way of doing
this: defining FP_NO_EXCEPTIONS before including soft-fp.h causes all
code handling exceptions to be stubbed out, and the rounding mode to
be hardwired for round-to-zero, to allow such optimizations for source
files where (a) the operation in question, for the particular types in
question, can never raise exceptions, but (b) some instances of the
operation for other types can, so the macros used in the file do
contain references to rounding or exceptions, albeit dead in that
particular file.

The uses in the Linux kernel are also unnecessary (clearing exceptions
at a point where they are already cleared).

This patch duly removes FP_CLEAR_EXCEPTIONS, making the SPARC code in
question use FP_NO_EXCEPTIONS and stop using exception-related macros.
