1b6e07f8e0 sparc: M7 optimized memcpy/mempcpy/memmove 
Support added to identify Sparc M7/T7/S7/M8/T8 processor capability.
Performance tests run on Sparc S7 using new code and old niagara4 code.

Optimizations for memcpy also apply to mempcpy and memmove
where they share code. Optimizations for memset also apply
to bzero as they share code.

For memcpy/mempcpy/memmove, performance comparison with niagara4 code:
Long word aligned data
  0-127 bytes - minimal changes
  128-1023 bytes - 7-30% gain
  1024+ bytes - 1-7% gain (in cache); 30-100% gain (out of cache)
Word aligned data
  0-127 bytes - 50%+ gain
  128-1023 bytes - 10-200% gain
  1024+ bytes - 0-15% gain (in cache); 5-50% gain (out of cache)
Unaligned data
  0-127 bytes - 0-70%+ gain
  128-447 bytes - 40-80%+ gain
  448-511 bytes - 1-3% loss
  512-4096 bytes - 2-3% gain (in cache); 0-20% gain (out of cache)
  4096+ bytes - ± 3% (in cache); 20-50% gain (out of cache)

Tested in sparcv9-*-* and sparc64-*-* targets in both multi and
non-multi arch configurations.

875cd54855 Use libm_alias_double for sparc. 
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes sparc libm function implementations use
libm_alias_double to define function aliases (with consequent

a55430cb0e sparc: Assume VIS3 support

the default implementation was built with a different name, a new

8644588807 Fix TLS relocations against local symbols on powerpc32, sparc32 and sparc64 
Normally, TLS relocations against local symbols are optimised by the linker
to be absolute.  However, gold does not do this, and so it is possible to
end up with, for example, R_SPARC_TLS_DTPMOD64 referring to a local symbol.
Since sym_map is left as null in elf_machine_rela for the special local
symbol case, the relocation handling thinks it has nothing to do, and so
the module gets left as 0.  Havoc then ensues when the variable in question
is accessed.

Before this fix, the main_local_gold program would receive a SIGBUS on
sparc64, and SIGSEGV on powerpc32.  With this fix applied, that test now
passes like the rest of them.

	* sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela):
	Assign sym_map to be map for local symbols, as TLS relocations

831bbd5527 Remove SPARC sqrt wrappers (bug 21973). 
This patch removes the SPARC-specific wrappers for sqrt and sqrtf.

These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling.  They also do not serve a useful optimization purpose.  GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time).  Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.

The removal of the wrappers also uncovers, and fixes, an old bug.
32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a
sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl
was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to
hand to check for the sqrtl symbol in those).  This disappeared,
probably with:

commit 8847f03770
Author: David S. Miller <davem@davemloft.net>
Date:   Tue Feb 28 22:37:58 2012 -0800

    Add sparc optimized sqrt{,f}.

Removing the wrappers brings back the generic ldbl-opt logic for
creating such compat symbols, and so restores the compat symbol that
should be there.  This could of course also be fixed in the wrappers -
but as noted above, the wrappers are optimizing a case it's not useful
to optimize, so the bug of the missing compat symbol serves to
illustrate the risks involved with the extra complexity of
architecture-specific function versions where not needed.

Tested with build-many-glibcs.py.

813378e9fe Obsolete matherr, _LIB_VERSION, libieee.a. 
This patch obsoletes support for SVID libm error handling (the system
where a user-defined function matherr is called on a libm function
error; only enabled if you also set _LIB_VERSION = _SVID_ or
_LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global
variable to control libm error handling.  matherr and _LIB_VERSION are
made into compat symbols, not supported for new ports or for static
linking.  The libieee.a object file (which sets _LIB_VERSION = _IEEE_,
so disabling errno setting for some functions) is also removed, and
all the related definitions are removed from math.h.

The manual already recommends against using matherr, and it's already
not supported for _Float128 functions (those use new wrappers that
don't support matherr, only errno) - this patch means that it becomes
possible to e.g. add sinf32 as an alias to sinf without that resulting
in undesired matherr support in sinf32 for existing glibc ports.
matherr support is not part of any standard supported by glibc (it was
removed in XPG4).

Because matherr is a function to be defined by the user, of course
user programs defining such a function will still continue to link; it
just quietly won't be used.  If they try to write to the library's
copy of _LIB_VERSION to enable SVID error handling, however, they will
get a link error (but if they define their own _LIB_VERSION variable,
they won't).

I expect the most likely case of build failures from this patch to be
programs with unconditional cargo-culted uses of -lieee (based on a
notion of "I want IEEE floating point", not any actual requirement for
that library).

Ideally, the new-port-or-static-linking case would use the new
wrappers used for _Float128.  This is not implemented in this patch,
because of the complication of architecture-specific (powerpc32 and
sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard
directly.  Thus, the old wrappers and __kernel_standard are still
built unconditionally, and _LIB_VERSION still exists in static libm.
But when the old wrappers and __kernel_standard are built in the
non-compat case, _LIB_VERSION and matherr are defined as macros so
code to support those features isn't actually built into static libm
or new ports' shared libm after this patch.

I intend to move to the new wrappers for static libm and new ports in
followup patches.  I believe the sqrt wrappers for powerpc32 and sparc
can reasonably be removed.  GCC already optimizes the normal case of
sqrt by generating code that uses a hardware instruction and only
calls the sqrt function if the argument was negative (if
-fno-math-errno, of course, it just uses the hardware instruction
without any check for negative argument being needed).  Thus those
wrappers will only actually get called in the case of negative
arguments, which is not a case it makes sense to optimize for.  But
even without removing the powerpc32 and sparc wrappers it should still
be possible to move to the new wrappers for static libm and new ports,
just without having those dubious architecture-specific optimizations
in static libm.

Everything said about matherr equally applies to matherrf and matherrl
(IA64-specific, undocumented), except that the structure of IA64 libm
means it won't be converted to using the new wrappers (it doesn't use
the old ones either, but its own error-handling code instead).

As with other tests of compat symbols, I expect test-matherr and
test-matherr-2 to need to become appropriately conditional once we
have a system for disabling such tests for ports too new to have the
relevant symbols.

Tested for x86_64 and x86, and with build-many-glibcs.py.

0572433b5b PowerPC64 ELFv2 PPC64_OPT_LOCALENTRY 
ELFv2 functions with localentry:0 are those with a single entry point,
ie. global entry == local entry, that have no requirement on r2 or
r12 and guarantee r2 is unchanged on return.  Such an external
function can be called via the PLT without saving r2 or restoring it
on return, avoiding a common load-hit-store for small functions.

This patch implements the ld.so changes necessary for this
optimization.  ld.so needs to check that an optimized plt call
sequence is in fact calling a function implemented with localentry:0,
end emit a fatal error otherwise.

The elf/testobj6.c change is to stop "error while loading shared
libraries: expected localentry:0 `preload'" when running
elf/preloadtest, which we'd get otherwise.

12d2dd7060 Optimize generic spinlock code and use C11 like atomic macros. 
This patch optimizes the generic spinlock code.

The type pthread_spinlock_t is a typedef to volatile int on all archs.
Passing a volatile pointer to the atomic macros which are not mapped to the
C11 atomic builtins can lead to extra stores and loads to stack if such
a macro creates a temporary variable by using "__typeof (*(mem)) tmp;".
Thus, those macros which are used by spinlock code - atomic_exchange_acquire,
atomic_load_relaxed, atomic_compare_exchange_weak - have to be adjusted.
According to the comment from  Szabolcs Nagy, the type of a cast expression is
unqualified (see http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_423.htm):
__typeof ((__typeof (*(mem)) *(mem)) tmp;
Thus from spinlock perspective the variable tmp is of type int instead of
type volatile int.  This patch adjusts those macros in include/atomic.h.
With this construct GCC >= 5 omits the extra stores and loads.

The atomic macros are replaced by the C11 like atomic macros and thus
the code is aligned to it.  The pthread_spin_unlock implementation is now
using release memory order instead of sequentially consistent memory order.
The issue with passed volatile int pointers applies to the C11 like atomic
macros as well as the ones used before.

I've added a glibc_likely hint to the first atomic exchange in
pthread_spin_lock in order to return immediately to the caller if the lock is
free.  Without the hint, there is an additional jump if the lock is free.

I've added the atomic_spin_nop macro within the loop of plain reads.
The plain reads are also realized by C11 like atomic_load_relaxed macro.

The new define ATOMIC_EXCHANGE_USES_CAS determines if the first try to acquire
the spinlock in pthread_spin_lock or pthread_spin_trylock is an exchange
or a CAS.  This is defined in atomic-machine.h for all architectures.

The define SPIN_LOCK_READS_BETWEEN_CMPXCHG is now removed.
There is no technical reason for throwing in a CAS every now and then,
and so far we have no evidence that it can improve performance.
If that would be the case, we have to adjust other spin-waiting loops
elsewhere, too!  Using a CAS loop without plain reads is not a good idea
on many targets and wasn't used by one.  Thus there is now no option to
do so.

Architectures are now using the generic spinlock automatically if they
do not provide an own implementation.  Thus the pthread_spin_lock.c files
in sysdeps folder are deleted.

e1d6e08dd6 Remove useless SPARC signbit aliases. 
The SPARC implementations of __signbit* functions have aliases
signbit, signbitf, signbitl.  These are useless, as they aren't
exported from the shared libraries (only the __signbit* functions are
exported, to be used by the type-generic signbit macro with older
compilers).  This patch removes the useless aliases.

f67d78192c Move wrappers to libm-compat-calls-auto 
This commit moves one step towards the deprecation of wrappers that
use _LIB_VERSION / matherr / __kernel_standard functionality, by
adding the suffix '_compat' to their filenames and adjusting Makefiles
and #includes accordingly.

New template wrappers that do not use such functionality will be added
by future patches and will be first used by the float128 wrappers.

8a9f4eb958 sparc: remove fdim sparc specific implementations 
The fdim and fdimf functions on sparc do not fully follow the standard
and do not set errno to ERANGE when the result overflows. Since glibc
2.24 this causes the two following tests to fail:

  Failure: fdim (max_value, -max_value): errno set to 0, expected 34 (ERANGE)
  Failure: fdim_upward (max_value, -max_value): errno set to 0, expected 34 (ERANGE)

It happens that using GCC with the generic C code generates very similar
code to the sparc specific implementations. Therefore this patches
remove them. Note it might still worth adding a vis3 specific version of
fdim on sparc32/sparcv9, this is done in a following patch to ease
backporting.

When building for sparc32/sparcv9 or sparc64, we assume that VIS

slightly suboptimal code.

bdf20beac1 sparc64: add a VIS3 version of ceil, floor and trunc 
sparc64 passes floating point values in the floating point registers.
As the the generic ceil, floor and trunc functions use integer
instructions, it makes sense to provide a VIS3 version consisting in
the the generic version compiled with -mvis3. GCC will then use
movdtox, movxtod, movwtos and movstow instructions.

sparc32 passes the floating point values in the integer registers, so it
doesn't make sense to do the same.

33ae5b17cd sparc: remove ceil, floor, trunc sparc specific implementations 
The ceil, floor and trunc functions on sparc do not fully follow the
standard and trigger an inexact exception when presented a value which
is not an integer. Since glibc 2.24 this causes a few tests to fail,
for instance:

  testing double (without inline functions)
  Failure: ceil (lit_pi): Exception "Inexact" set
  Failure: ceil (-lit_pi): Exception "Inexact" set
  Failure: ceil (min_subnorm_value): Exception "Inexact" set
  Failure: ceil (min_value): Exception "Inexact" set
  Failure: ceil (0.1): Exception "Inexact" set
  Failure: ceil (0.25): Exception "Inexact" set
  Failure: ceil (0.625): Exception "Inexact" set
  Failure: ceil (-min_subnorm_value): Exception "Inexact" set
  Failure: ceil (-min_value): Exception "Inexact" set
  Failure: ceil (-0.1): Exception "Inexact" set
  Failure: ceil (-0.25): Exception "Inexact" set
  Failure: ceil (-0.625): Exception "Inexact" set

I tried to fix that by using the same strategy than used on other
architectures, that is by saving the FSR register at the beginning
and restoring it at the end of the function. When doing so I noticed
a comment that this operation might be very costly, so I decided to
do some benchmarks.

The benchmarks below represent the time required to run each of the
function 60 millions of times with different input value. I have done
that in the basic V9 code, the VIS2 code, and using the default C
implementation of the libc, for both sparc32 and sparc64, on a Niagara
T1 based machine and an UltraSparc IIIi. Given I don't have access to a
more recent machine), I haven't been able to test the VIS3 version. Also
it should be noted that it doesn't make sense to do this benchmark for
V8 or earlier as in that case we use the default C implementation. The
results are available in the table below, the "+ fix" version correspond
to the one saving and restoring the FSR.

The first thing that should be noted is that the C implementation is
always faster on the Niagara T1 based machine. On the UltraSparc IIIi
the float version on sparc32 is also faster.

Coming back about the fix saving and restoring the FSR, it appears
it has a big impact as expected. In that case the C implementation is
always faster than the fixed implementations.

This patch therefore removes the sparc specific implementations in
favor of the generic ones.

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.

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).

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.
