2021-01-02Update copyright dates with scripts/update-copyrightsPaul Eggert
I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

2019-11-27sparc: Use atomic compiler builtins on sparcAdhemerval Zanella
This patch removes the arch-specific atomic instruction, relying on compiler builtins. The __sparc32_atomic_locks support is removed and a configure check is added to check if compiler uses libatomic to implement CAS. It also removes the sparc specific sem_* and pthread_barrier_* implementations. It in turn allows buidling against a LEON3/LEON4 sparcv8 target, although it will still be incompatible with generic sparcv9. Checked on sparcv9-linux-gnu and sparc64-linux-gnu. I also checked with build against sparcv8-linux-gnu with -mcpu=leon3. Tested-by: Andreas Larsson <andreas@gaisler.com>

Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !

2019-03-22Refactor hp-timing rtld usageAdhemerval Zanella
This patch refactor how hp-timing is used on loader code for statistics report. The HP_TIMING_AVAIL and HP_SMALL_TIMING_AVAIL are removed and HP_TIMING_INLINE is used instead to check for hp-timing avaliability. For alpha, which only defines HP_SMALL_TIMING_AVAIL, the HP_TIMING_INLINE is set iff for IS_IN(rtld). Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu.

2018-09-27Use copysign functions not __copysign functions in glibc libm.Joseph Myers
Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __copysign functions to call the corresponding copysign names instead, with asm redirection to __copysign when the calls are not inlined (all cases are inlined except for IBM long double for powerpc soft-float / e500v1). This eliminates the need for an inline function defining __copysign in terms of __builtin_copysign. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (MATH_REDIRECT_BINARY_ARGS): New macro.

2018-09-14Use rint functions not __rint functions in glibc libm.Joseph Myers
Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __rint functions to call the corresponding rint names instead, with asm redirection to __rint when the calls are not inlined. The x86_64 math_private.h is removed as no longer useful after this patch. This patch is relative to a tree with my floor patch <https://sourceware.org/ml/libc-alpha/2018-09/msg00148.html> applied, and much the same considerations arise regarding possibly replacing an IFUNC call with a direct inline expansion. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (rint): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_rint.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_rintf.c: Likewise. * sysdeps/alpha/fpu/s_rint.c: Likewise. * sysdeps/alpha/fpu/s_rintf.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/ieee754/dbl-64/s_rint.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_rint.c: Likewise. * sysdeps/ieee754/float128/s_rintf128.c: Likewise. * sysdeps/ieee754/flt-32/s_rintf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_rintl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_rintl.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rint.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintl.c: Likewise. * sysdeps/powerpc/fpu/s_rint.c: Likewise. * sysdeps/powerpc/fpu/s_rintf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Likewise. * sysdeps/riscv/rvf/s_rintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/math_private.h: Remove file. * math/e_scalb.c (invalid_fn): Use rint functions instead of __rint variants. * math/e_scalbf.c (invalid_fn): Likewise. * math/e_scalbl.c (invalid_fn): Likewise. * sysdeps/ieee754/dbl-64/e_gamma_r.c (__ieee754_gamma_r): Likewise. * sysdeps/ieee754/flt-32/e_gammaf_r.c (__ieee754_gammaf_r): Likewise. * sysdeps/ieee754/k_standard.c (__kernel_standard): Likewise. * sysdeps/ieee754/k_standardl.c (__kernel_standard_l): Likewise. * sysdeps/ieee754/ldbl-128/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-96/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrint.c (__llrint): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrintf.c (__llrintf): Likewise.

2017-11-30Remove SPARC lllrint aliases.Joseph Myers
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. Tested (compilation only) with build-many-glibcs.py for sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrint.S (__lllrint): Remove alias.

2017-11-29Fix missing sparcv9 --disable-multi-arch fabsl compat symbol (bug 22229).Joseph Myers
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. [BZ #22229] * sysdeps/sparc/sparc32/sparcv9/fpu/s_fabs.S: Include <math_ldbl_opt.h>.

This leads to some code simplification, mostly on multiarch build where there is only one variant instead of previously two (whether binutils supports VIS3 instructions or not).

32-bit SPARC libm should have compat symbols for copysignl (GLIBC_2.0), fabsl (GLIBC_2.0), fmal (GLIBC_2.1), pointing to the double functions; they were present in glibc 2.8, for example, but are now missing, probably when optimized SPARC function implementations were added without appropriate compat symbol handling.

2017-09-13Define and use libm_alias_double.Joseph Myers
Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_double macro and uses it in the type-generic templates. This macro handles defining aliases for double, and for long double in the NO_LONG_DOUBLE case. It also handles defining compat symbols for long double = double for architectures that changed their long double format. By so doing, it eliminates the need for the M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single declare_mgen_alias call in each template now suffices to define all required compat symbols. When used for more double functions (not based on type-generic templates), I expect it will eliminate the need for most ldbl-opt wrappers for such functions. A few special cases are needed. __clog10l is a public symbol (for historical reasons) so needs to be given appropriate compat versions for architectures that changed their long double format, but is not defined as an alias using the normal macros since __clog10* are *not* public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and log1p, the changes adding errno setting support for those functions left compat symbols pointing directly to the non-errno-setting implementations. There is no requirement for the compat symbols not to set errno; that just made for the simplest patches at that time. Now, with these common macros, it's natural to redirect the compat symbols to the errno-setting wrappers, which I intend to do in a separate patch. Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt platforms the stripped libm.so binaries are changed (disassembly unchanged) because the details of how the clog10l compat symbol is created mean it ceases to be weak as it was before; for other platforms, stripped libm.so binaries are unchanged. 2017-09-13 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/libm-alias-double.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Likewise. * sysdeps/generic/math-type-macros-double.h: Include <libm-alias-double.h>.

2017-08-21Remove SPARC sqrt wrappers (bug 21973).Joseph Myers
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 8847f0377003fbfe9cbe951ce9f8717d74f26247 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.

2017-08-21Obsolete matherr, _LIB_VERSION, libieee.a.Joseph Myers
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.

2017-06-06Optimize generic spinlock code and use C11 like atomic macros.Stefan Liebler
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.

2017-04-06sparc: Fix .udiv plt on libcAdhemerval Zanella
With the removal of divdi3 object from sparcv9-linux-gnu build, its definition came from libgcc and its functions internall calls .udiv. Since glibc also exports these symbols for compatibility reasons, it will end up creating PLT calls internally in libc.so. To avoid it, this patch uses the linker option --wrap to replace all the internal libc.so .udiv calls to the wrapper __wrap_.udiv. Along with strong alias in the udiv implementations, it makes linker do local calls. Checked on sparcv9-linux-gnu. * sysdeps/sparc/sparc32/Makefile (libc.so-gnulib): New rule. * sysdeps/sparc/sparc32/sparcv8/udiv.S (.udiv): Make a strong_alias to __wrap_.udiv. * sysdeps/sparc/sparc32/sparcv9/udiv.S (.udiv): Likewise. * sysdeps/sparc/sparc32/udiv.S (.udiv): Likewise.

2017-01-04Move wrappers to libm-compat-calls-autoGabriel F. T. Gomes
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.

2016-09-15nptl: Consolidate sem_init implementationsAdhemerval Zanella
Current sparc32 sem_init and default one only differ on sem.newsem.pad initialization. This patch removes sparc32 and sparc32v9 sem_init arch specific implementation and set sparc32 to use nptl default one. The default implementation sets the required sem.newsem.pad to 0 (which is ununsed in other architectures). I checked on i686 and a sparc32v9 build. * nptl/sem_init.c (sem_init): Init pad value to 0. * sysdeps/sparc/sparc32/sem_init.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_init.c: Likewise.
2016-09-15nptl: Remove sparc sem_waitAdhemerval Zanella
This patch removes the sparc32 sem_wait.c implementation since it is identical to default nptl one. The sparcv9 is no longer required with the removal. Checked with a sparcv9 build. * sysdeps/sparc/sparc32/sem_wait.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_wait.c: Likewise.
2016-09-15nptl: Consolidate sem_open implementationsAdhemerval Zanella
Current sparc32 sem_open and default one only differ on: 1. Default one contains a 'futex_supports_pshared' check. 2. sem.newsem.pad is initialized to zero. This patch removes sparc32 and sparc32v9 sem_open arch specific implementation and instead set sparc32 to use nptl default one. Using 1. is fine since it should always evaluate 0 for Linux (an optimized away by the compiler). Adding 2. to default implementation should be ok since 'pad' field is used mainly on sparc32 code. I checked on i686 and checked a sparc32v9 build. * nptl/sem_open.c (sem_open): Init pad value to 0. * sysdeps/sparc/sparc32/sem_open.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_open.c: Likewise.
2016-09-01Make common fdim implementation generic.Paul E. Murphy
The only difference is the usage of math_narrow_eval when building s_fdiml.c. This should be harmless for long double, but I did observe some code generation changes on m68k, but lack the resources to test it. Likewise, to more easily support overriding symbol generation, the aliasing macros are always conditionally defined on their absence to reduce boilerplate. I also ran builds for i486, ppc64, sparcv9, aarch64, s390x and observed no changes to s_fdim* objects.

2016-08-05sparc32/sparcv9: add a VIS3 version of fdimAurelien Jarno
sparc32 passes floating point values in the integer registers. VIS3 instructions gives access to the movwtos instruction to directly transfer a value from an integer register to a floating point register. Therefore it makes sense to provide a VIS3 version consisting in the generic version compiled with -mvis3.

2016-08-05sparc: remove fdim sparc specific implementationsAurelien Jarno
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. Changelog: * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile [$(subdir) = math && $(have-as-vis3) = yes] (libm-sysdep_routines): Remove s_fdimf-vis3, s_fdim-vis3. * sysdeps/sparc/sparc32/fpu/s_fdim.S: Delete file. * sysdeps/sparc/sparc32/fpu/s_fdimf.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdimf-vis3.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdimf.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_fdim.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_fdimf.S: Likewise. * sysdeps/sparc/sparc64/fpu/s_fdim.S: Likewise. * sysdeps/sparc/sparc64/fpu/s_fdimf.S: Likewise.
2016-08-05sparc: build with -mvis on sparc32/sparcv9 and sparc64Aurelien Jarno
When building for sparc32/sparcv9 or sparc64, we assume that VIS instructions are available and use them in the sparc specific assembly code. However we do not tell GCC to use such instructions, resulting in slightly suboptimal code. Fix that by passing -Wa,-Av9a -mvis to GCC. Changelog: * sysdeps/sparc/sparc32/sparcv9/Makefile (sysdep-CFLAGS): Add -mvis. * sysdeps/sparc/sparc64/Makefile (sysdep-CFLAGS): New. Define to -Wa,-Av9a -mvis.

2016-08-02sparc: remove ceil, floor, trunc sparc specific implementationsAurelien Jarno
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.

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.

2016-07-01SPARC: fix nearbyint on sNaN inputAurelien Jarno
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. Changelog: * sparc/sparc32/sparcv9/fpu/s_nearbyint.S (__nearbyint): Trigger an invalid exception for a sNaN input. * sparc/sparc32/sparcv9/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise * sparc/sparc64/fpu/s_nearbyint.S (__nearbyint): Likewise. * sparc/sparc64/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise.
2016-01-15New pthread_barrier algorithm to fulfill barrier destruction requirements.Torvald Riegel
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.

2015-09-11Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers
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).
