* Fix typo in sincos32.h inclusion guard.Stefan Liebler2017-09-252-1/+7
| | | | | | | | | | This patch fixes a typo in inclusion guard in sincos32.h. ChangeLog: * sysdeps/ieee754/dbl-64/sincos32.h [SINCCOS32_H]: Remove define. [SINCOS32_H]: Define.
* New expf and exp2f version without SVID compat wrapperSzabolcs Nagy2017-09-2534-9/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the expf and exp2f error handling semantics to only set errno accoring to POSIX rules. New symbol version is introduced at GLIBC_2.27. The old wrappers are kept for compat symbols. Internal calls to __expf now get the new error semantics, this seems to only affect sysdeps/i386/fpu/s_expm1f.S where the errno-only behaviour should be correct. ia64 needed assembly change to have the new and compat versioned symbol map to the same function. All linux libm abilists are updated. * math/Versions (expf): New libm symbol at GLIBC_2.27.

* Optimized generic expf and exp2f with wrappersSzabolcs Nagy2017-09-2516-567/+421
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on new expf and exp2f code from https://github.com/ARM-software/optimized-routines/ with wrapper on aarch64: expf reciprocal-throughput: 2.3x faster expf latency: 1.7x faster without wrapper on aarch64: expf reciprocal-throughput: 3.3x faster expf latency: 1.7x faster without wrapper on aarch64: exp2f reciprocal-throughput: 2.8x faster exp2f latency: 1.3x faster libm.so size on aarch64: .text size: -152 bytes .rodata size: -1740 bytes expf/exp2f worst case nearest rounding error: 0.502 ulp worst case non-nearest rounding error: 1 ulp Error checks are inline and errno setting is in separate tail called functions, but the wrappers are kept in this patch to handle the _LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls and once for __expf_finite calls on targets where the new code is used.) Double precision arithmetics is used which is expected to be faster on most targets (including soft-float) than using single precision and it is easier to get good precision result with it. Const data is kept in a separate translation unit which complicates maintenance a bit, but is expected to give good code for literal loads on most targets and allows sharing data across expf, exp2f and powf. (This data is disabled on i386, m68k and ia64 which have their own expf, exp2f and powf code.) Some details may need target specific tweaks: - best convert and round to int operation in the arg reduction may be different across targets. - code was optimized on fma target, optimal polynomial eval may be different without fma. - gcc does not always generate good code for fp bit representation access via unions or it may be inherently slow on some targets. The libm-test-ulps will need adjustment because.. - The argument reduction ideally uses nearest rounded rint, but that is not efficient on most targets, so the polynomial can get evaluated on a wider interval in non-nearest rounding mode making 1 ulp errors common in that case. - The polynomial is evaluated such that it may have 1 ulp error on negative tiny inputs with upward rounding. * math/Makefile (type-float-routines): Add math_errf and e_exp2f_data. * sysdeps/aarch64/fpu/math_private.h (TOINT_INTRINSICS): Define.

* resolv_test.c: also cope with CONNREFUSED errors returned by recvfromSamuel Thibault2017-09-252-1/+9
| | | | | | | | | | | server_thread_udp_process_one already takes care of calling sendto() instead of xsendto to be able to ignore the case where the client has closed the socket. Depending on the TCP/IP stack behavior, this error could be notified later through recvfrom(), so we need to ignore it there too. * support/resolv_test.c (server_thread_udp_process_one): Call recvfrom instead of xrecvfrom, and ignore ECONNREFUSED errors.

* Let fpclassify use the builtin when optimizing for size in C++ mode (bug 22146)Gabriel F. T. Gomes2017-09-222-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When optimization for size is on (-Os), fpclassify does not use the type-generic __builtin_fpclassify builtin, instead it uses __MATH_TG. However, when library support for float128 is available, __MATH_TG uses __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, libstdc++ undefines (in cmath) many macros from math.h, including fpclassify, so that it can provide its own functions. However, during its configure tests, libstdc++ just tests for the availability of the macros (it does not undefine them, nor does it provide its own functions). Finally, when libstdc++ is configured with optimization for size enabled, its configure tests include math.h and get the definition of fpclassify that uses __MATH_TG (and __builtin_types_compatible_p). Since libstdc++ does not undefine the macros during its configure tests, they fail. This patch lets fpclassify use the builtin in C++ mode, even when optimization for size is on. This allows the configure test in libstdc++ to work. Tested for powerpc64le and x86_64. [BZ #22146] math/math.h: Let fpclassify use the builtin in C++ mode, even when optimazing for size.
* Remove Banner mechanism.Joseph Myers2017-09-225-17/+13
| | | | | | | | | | | | | | | | | | | | This patch removes the Banner mechanism, with the last remaining Banner file replaced by a contrib.texi entry. This accords with the principle that the output of running libc.so.6 is not the place to credit particular contributions (the manual is), and with all other configuration options not mentioned there, it doesn't seem appropriate to focus there on the one question of whether the one remaining piece configured as an add-on was enabled or not. Tested for x86_64. * csu/Makefile (generated): Do not add version-info.h. (before-compile): Likewise. (all-Banner-files): Remove variable. ($(objpfx)version-info.h): Remove rule. * csu/version.c (banner): Do not include "version-info.h". * libidn/Banner: Remove. * manual/contrib.texi (Simon Josefsson): New entry.
* Remove conditional on LDBL_MANT_DIG from e_lgammal_r.cGabriel F. T. Gomes2017-09-213-10/+9
| | | | | | | | | | | | | | | | The IEEE 754 implementation of lgammal in sysdeps/ieee754/ldbl-128/ used to be shared by IBM's implementation in sysdeps/ieee754/ldbl-128ibm/ (by an inclusion of the source file). In order for the algorithm to work for IBM's implementation, a check for LDBL_MANT_DIG was required. Since the source file is no longer shared, the requirement for the check is gone. This patch removes the conditionals. Tested for powerpc64le and s390x. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Remove conditionals on LDBL_MANT_DIG. * sysdeps/ieee754/ldbl-128ibm/e_lgammal_r.c (__ieee754_lgammal_r): Likewise.
* ldbl-128ibm: Automatic replacing of _Float128 and L()Gabriel F. T. Gomes2017-09-217-2253/+2253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ldbl-128ibm implementation of j0l, j1l, lgammal_r, and cbrtl, as well as the tables used by expl were copied from ldbl-128. However, the original files used _Float128 for the type and L() for the literal suffix. This patch uses the following sed command to rewrite _Float128 as long double and L(x) as xL (for e_expl.c, e_j0l.c, e_j1l.c, e_lgammal_r.c, and t_expl.h): sed -i <filename> \ -e "/^#define _Float128 long double/d" \ -e "/^#define L(x) x ## L/d" \ -e "/L(/s/)/L/" \ -e "/L(/s/L(//" \ -e "s/_Float128/long double/g" For sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c, this sed command incorrectly replaces a few occurrences of L(), so the following command is used instead: sed -i sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c \ -e "/^#define _Float128 long double/d" \ -e "/^#define L(x) x ## L/d" \ -e "s/L(0\.3\{40\})/0.3333333333333333333333333333333333333333L/" \ -e "s/L(3\.7568280825958912391243e-1)/3.7568280825958912391243e-1L/" \ -e "/L(/s/)/L/" \ -e "/L(/s/L(//" \ -e "s/_Float128/long double/g" Tested for powerpc64le with patched [1] and unpatched gcc.

* ldbl-128ibm: Copy implementations from ldbl-128 instead of including themGabriel F. T. Gomes2017-09-217-12/+3827
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some files under sysdeps/ieee754/ldbl-128ibm/ are able to reuse the implementation in sysdeps/ieee754/ldbl-128/ by defining _Float128 to long double. This relied on compiler support for _Float128 being disabled. On powerpc, such support was disabled by default, however, it got enabled by default [1] in GCC 8. This patch copies the implementations from ldbl-128 to ldbl-128ibm. The uses of _Float128 and L() are kept intact in this patch and are replaced with a script in a subsequent patch.

* powerpc: Add redirection for finitef128, isinf128, and isnanf128Gabriel F. T. Gomes2017-09-214-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On powerpc64le, compiler support for float128 is not enabled by default on gcc. To enable it, the flag -mfloat128 must be passed as a command line option to the compiler. This means that only the few files that actively have -mfloat128 passed as an argument get compiler support for float128, whereas all other files don't. When -mfloat128 becomes enabled by default on powerpc [1], all the files that do not currently have compiler support for float128 enabled during their compilation, will start to have it. This will lead to build errors in s_finite.c, s_isinf.c, and s_isnan.c. The errors are due to the unintended macro expansion of __finitef128 to __redirect_finitef128 in math/bits/mathcalls-helper-functions.h. In that header, __MATHDECL_1 takes '__finite' and 'f128' as arguments and concatenates them. However, since '__finite' has been redefined in s_finite.c, the function declaration becomes __redirect_finitef128: extern int __redirect___finitef128 (_Float128 __value) __attribute__ ((__nothrow__ )) __attribute__ ((__const__)); This declaration itself is OK. The problem arises when include/math.h creates the hidden prototype ('hidden_proto (__finitef128)'), which expands to: extern __typeof (__finitef128) __finitef128 __attribute__ ((visibility ("hidden"))); Since __finitef128 is not declared, __typeof fails. This effect was already true for the 'float' and 'long double' versions and is now true for float128. Likewise for isinsff128 and isnanf128. This patch defines __finitef128 as __redirect___finitef128 in sysdeps/powerpc/powerpc64/fpu/multiarch/s_finite.c, similarly to what's done for the float and long double versions of these functions, to get rid of the build error. Likewise for isinff128 and isnanf128.

* powerpc64le: Add -mfloat128 to tst-strtod-nan-locale testcaseGabriel F. T. Gomes2017-09-212-0/+9

* Fix BZ# 22180.Paul Pluzhnikov2017-09-215-4/+180
| | | | | | | | | | | | | | | | | | | POSIX requires that dlclose() and exit() be thread safe, therefore you can have one thread in the middle of dlclose() and another thread executing exit() without causing any undefined behaviour on the part of the implementation. The existing implementation had a flaw that exit() exit handler processing did not consider a concurrent dlclose() and would not mark already run exit handlers using the ef_free flavour. The consequence of this is that a concurrent exit() with dlclose() will run all the exit handlers that dlclose() had not yet run, but then will block on the loader lock. The concurrent dlclose() will continue to run all the exit handlers again (twice) in violation of the Itanium C++ ABI requirements for __cxa_atexit(). This commit fixes this by having exit() mark all handlers with ef_free to ensure that concurrent dlclose() won't re-run registered exit handlers that have already run.
* Remove non-add-on Banner files.Joseph Myers2017-09-218-14/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various subdirectories of glibc include Banner files to put some text in the output of executing libc.so.6, under "Available extensions". Some of those subdirectories (e.g. crypt) may originally have been add-ons (and so optional, so a particular glibc build might or might not have included them), but except for libidn they aren't now (or if only included in some builds, in the case of soft-fp, the inclusion depends on the architecture for which glibc is configured rather than having any glibc configuration for which it's an optional feature), and it doesn't seem useful for the libc.so.6 output to call out a few features like that. This patch removes the non-add-on Banner files, updating contrib.texi where they noted contributions not otherwise mentioned there. Tested for x86_64. * crypt/Banner: Remove file. * nptl/Banner: Likewise. * resolv/Banner: Likewise. * soft-fp/Banner: Likewise. * nptl/Makefile ($(objpfx)banner.h): Remove rule.

This eliminates many ldbl-opt wrappers round these function implementations. Tested for x86_64, and with build-many-glibcs.py. All installed stripped shared libraries are unchanged except for libm.so on powerpc64le. As noted for a previous patch, powerpc64le's use of ldbl-opt means various long double functions get defined using long_double_symbol which gives them an explicit symbol version in the object files, and this patch results in some such functions using weak_alias instead (because powerpc64le never had a previous version of these functions for long double = double); both produce a valid libm.so with the same public symbols at the same versions, but macros expanding to call weak_alias is cleaner in this case. * math/s_fmal.c: Include <libm-alias-ldouble.h>.

They are only present for a limited set of libm functions, not all those that would need implementing for any hypothetical new long double format, and only for long double (plus sqrtf128), not for other floating-point types. I removed the corresponding ENOSYS tests in the testsuite in <https://sourceware.org/ml/libc-alpha/2013-05/msg00599.html>. I think these stubs are an inherently different case from stubs for functionality needing OS-specific implementations, since floating-point formats are generally standardized between modern processors (a new long double format does not seem likely - I'd expect new ports all to have long double = binary128 or long double = binary64 - though _Float16 functions *f16 are entirely possible in future) and libm functions are generally only expected to fail for domain / range / pole errors, not for other unknown system-specific conditions the way the functions needing OS-specific implementations may fail. This patch removes these stub implementations. The effect (which, as noted above, was actually mostly already the case, given the incompleteness of the set of stubs, and was certainly the case if you wanted your libm port to *work* rather than just build) is that any new long double format needs to provide a full set of functions for the build to succeed; any port using ldbl-128 needs to provide sqrtl (possibly using the soft-fp version from another port); any port using ldbl-96 needs to provide all those functions that all of x86_64/i386/ia64/m68k provide rather than getting from the ldbl-96 directory; any port with _Float128 as a type with a distinct format needs to provide sqrtf128. Tested for x86_64.

* [BZ #21745] powerpc: build some IFUNC math functions for libc and libmTulio Magno Quites Machado Filho2017-09-153-17/+36
| | | | | | | | | | | | | | | | | | | | | | | Some math functions have to be distributed in libc because they're required by printf. libc and libm require their own builds of these functions, e.g. libc functions have to call __stack_chk_fail_local in order to bypass the PLT, while libm functions have to call __stack_chk_fail. While math/Makefile treat the generic cases, i.e. s_isinff, the multiarch Makefile has to treat its own files, i.e. s_isinff-ppc64. [BZ #21745] * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile: [$(subdir) = math] (sysdep_calls): New variable. Has the previous contents of sysdep_routines, but re-sorted.. [$(subdir) = math] (sysdep_routines): Re-use the contents from sysdep_calls. [$(subdir) = math] (libm-sysdep_routines): Remove the functions defined in sysdep_calls and replace by the respective m_* names. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_isnan-ppc64.S: (compat_symbol): Undefine to avoid duplicated compat symbols in libc.

* Make more libm functions into weak aliases.Joseph Myers2017-09-1469-97/+395

This is not at all limited to cases where there is an internal call that has namespace reasons to need to call __<func> instead of <func>. The common macros for creating libm function aliases work on the basis of public function names all being aliases; that is, they define aliases for functions using the above pattern. Thus, where a function just defines the public name <func> directly, changing that to be a weak alias enables a subsequent conversion to the common macros to retain the exact existing symbols (and so be testable by comparison of stripped binaries). This patch converts many existing functions to use the weak alias pattern, as preparation for subsequent conversions to common macros. I do expect that _FloatN/_FloatNx function aliases will end up needing new variants of the common macros that do *not* create the original float / double / long double name of a function - for cases where that name is created specially to give it a particular symbol version, for example - but for functions that can use the most common macros to create all the public names as aliases, it makes sense for them to do so.

| | | | | | | | | | | | | | | | | | | | 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_float128 macro and uses it in the type-generic templates. (_Float128 functions will end up with _Float64x aliases on powerpc64le, but not on x86_64/x86/ia64 because _Float64x has long double format there, and the macro will provide a single place for the conditionals for that choice, as well as for once ldbl-128 functions always build *f128 and need conditionals for whether to have *l aliases.) Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-float128.h: New file. * sysdeps/generic/math-type-macros-float128.h: Include <libm-alias-float128.h>.
