2017-12-05math: Use sign as double for reduced case in sinfAdhemerval Zanella
This patch avoid an extra floating point to integer conversion in reduced internal function for generic sinf by defining the sign as double instead of integers. There is no much difference on Haswell with GCC 7.2.1: Before After min 9.11 9.108 mean 21.982 21.9224 However H.J. Lu reported gains on Skylake: Before: "sinf": { "": { "duration": 3.4044e+10, "iterations": 1.9942e+09, "max": 141.106, "min": 7.704, "mean": 17.0715 } } After: "sinf": { "": { "duration": 3.40665e+10, "iterations": 2.03199e+09, "max": 95.994, "min": 7.704, "mean": 16.765 } } Checked on x86_64-linux-gnu. * sysdeps/ieee754/flt-32/s_sinf.c (ones): Define as double. (reduced): Use ones as double instead of integer.
2017-12-05[PATCH] fix sinf(NAN)Szabolcs Nagy
sinf(NAN) should not signal invalid fp exception so use isless instead of < where NAN is compared. this makes the sinf tests pass on aarch64. * sysdeps/ieee754/flt-32/s_sinf.c (sinf): Use isless.
2017-12-05Support defining strfromf64, strfromf32x aliases.Joseph Myers
This patch adds support for defining strfromf64 and strfromf32x aliases of strfromd when the corresponding types are enabled. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float64 / _Float32x changes. * stdlib/strfromd.c: Include <bits/floatn.h>. [__HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (strfromf64): Define and later undefine as macro and define as weak alias. [__HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (strfromf32x): Likewise.
2017-12-05Add headers for _Float64, _Float32x testing.Joseph Myers
This patch adds the headers required for testing _Float64 and _Float32x function aliases (using double ulps). The corresponding makefile support will be included in the patch that actually adds those aliases; there doesn't seem much point in adding makefile conditionals for testing something that will be available unconditionally. In conjunction with other _Float64 / _Float32x changes, test for x86_64 and with build-many-glibcs.py. * math/test-float32x.h: New file. * math/test-float64.h: Likewise.
2017-12-05Support _Float64, _Float32x in libm_alias_double.Joseph Myers
This patch makes the libm_alias_double macros support creating _Float64 and _Float32x aliases, in preparation for enabling glibc support for those types. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float64 / _Float32x changes. * sysdeps/generic/libm-alias-double.h: Include <bits/floatn.h>. (libm_alias_double_other_r_f64): New macro. (libm_alias_double_other_r_f32x): Likewise. (libm_alias_double_other_r): Use libm_alias_double_other_r_f64 and libm_alias_double_other_r_f32x. (libm_alias_double_r): Use semicolon before call to libm_alias_double_other_r. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Include <bits/floatn.h>. (libm_alias_double_other_r_f64): New macro. (libm_alias_double_other_r_f32x): Likewise. (libm_alias_double_other_r): Use libm_alias_double_other_r_f64 and libm_alias_double_other_r_f32x.
2017-12-05s_sinf.c: Replace floor with simple castsH.J. Lu
Since s_sinf.c either assigns the return value of floor to integer or passes double converted from integer to floor, this patch replaces floor with simple casts. Also since long == int for 32-bit targets, we can use long instead of int to avoid 64-bit integer for 64-bit targets. On Skylake, bench-sinf reports performance improvement: Before After Improvement max 130.566 129.564 30% min 7.704 7.706 0% mean 21.8188 19.1363 30% * sysdeps/ieee754/flt-32/s_sinf.c (reduced): Replace long with int. (SINF_FUNC): Likewise. Replace floor with simple casts.

2017-12-05tilegx: work around vector insn bug in gccChris Metcalf
Avoid an issue in gcc where some of the vector (aka SIMD) ops will sometimes end up getting wrongly optimized out. We use these instructions in many of the string implementations. If/when we have an upstreamed fix for this problem in gcc we can conditionalize the use of the extended assembly workaround in glibc.
2017-12-05Linux: Implement interfaces for memory protection keysFlorian Weimer
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.

2017-12-05support/tst-test_compare: Fix 32-bit/64-bit expected output mismatchFlorian Weimer
The use of a long type resulted in test output differences between 32-bit and 64-bit architectures, causing the test to fail on 32-bit architectures.

2017-12-04Use __floor not floor in sinf.Joseph Myers
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.

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.
2017-12-04S390: Fix backtrace in vdso functions.Stefan Liebler
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. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise.

2017-12-02Use libm_alias_double for remaining powerpc functions.Joseph Myers
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).

2017-12-01Define powerpc64 lroundl compat symbol only once.Joseph Myers
sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c defines the lroundl compat symbol, version GLIBC_2_1, twice, once based on llround and once based on __lround. Those are aliases for each other (llround weak, __lround strong), but defining it twice does not make sense. This patch changes it to define the compat symbol once only, matching how libm_alias_double defines it. Tested with build-many-glibcs.py for its powerpc64 configurations. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c [LONG_DOUBLE_COMPAT(libm, GLIBC_2_1)] (lroundl): Do not define compat symbol based on llround.
2017-12-01Base powerpc logbl compat symbols on __logb not logb.Joseph Myers
Some powerpc logb implementations define a compat symbol for logbl based on logb, whereas libm_alias_double defines such a compat symbol based on __logb instead. This difference (logb is weak, __logb isn't) is enough to result in different installed stripped shared libraries. The difference in the installed libraries isn't significant, but first changing the compat_symbol calls helps make it possible to validate a subsequent change to use libm_alias_double by comparison of libraries, so this patch does such a preliminary change. Tested with build-many-glibcs.py for all its hard-float powerpc configurations. * sysdeps/powerpc/power7/fpu/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Define as compat symbol based on __logb, not on logb. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb.c [LONG_DOUBLE_COMPAT (libm, GLIBC_2_0)] (logbl): Likewise.

Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes powerpc fabs and fma use libm_alias_double to define function aliases. This brings in automatic symbol versioning compat handling, so the powerpc32 and powerpc64 wrappers that added such handling to the generic sysdeps/powerpc/fpu versions are removed as no longer required (there are no sysdeps directory ordering issues that would necessitate keeping trivial wrappers there).

2017-11-30Rework m68k libm functions to use declare_mgen_alias.Joseph Myers
Many m68k libm functions use their own system to share code between different types and functions, involving defining macros before including code for another function (for example, s_atan.c also acts as a template that can define other functions). Thes files serving as templates generate function aliases directly with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c. To be prepared to generate _Float32, _Float64 and _Float32x function aliases, this needs changing so that the libm_alias_* macros get used instead. As the macro to use varies depending on the type, that would mean additional macros to define in several different places to get the appropriate alias-generation macro used in each case. Rather than adding to the m68k-specific mechanisms, this patch converts the functions in question to use something closer to the math/ type-generic template mechanism. After this patch, these functions have m68k-specific templates such as s_atan_template.c, but those templates use all the same macros as in the math/ templates, such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias. There is no automatic generation of the files such as s_atan.c that include the appropriate math-type-macros-*.h header and the template file (the existing automatic generation logic is only applicable for the fixed set of templates listed in math/ - and sysdeps sources always override files generated that way), so those files are still checked in, but they are all the obvious two-line files (with one additional definition in the case of the expm1 implementations), rather than making e.g. s_atan.c special. Functions are only converted where they should have aliases for _FloatN / _FloatNx types. Those m68k functions that do not generate public names (those that only generate __ieee754_*, with wrappers generating the public names, and classification functions that only exist once per format not once per type so don't get aliases) are unchanged. However, log1p (public names generated by wrapper) and significand (not provided for new types so no new aliases needed) needed changing because they previously included the atan implementations. Now, s_significand.c is the main implementation for functions with that prototype and using the old implementation approach, while log1p includes it in place of atan. Any further cleanups in this area (which preserve the proper set of functions getting aliases defined by libm_alias_float and libm_alias_double) are of course welcome, just not needed for the goals of this patch. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/m68k/m680x0/fpu/s_atan_template.c: New file. * sysdeps/m68k/m680x0/fpu/s_ceil_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cos_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabs_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floor_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_frexp_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modf_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquo_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sin_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincos_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tan_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanh_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_atan.c: Reimplement to use s_atan_template.c. * sysdeps/m68k/m680x0/fpu/s_atanf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_atanl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_ceil.c: Reimplement to use s_ceil_template.c. * sysdeps/m68k/m680x0/fpu/s_ceilf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_ceill.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cos.c: Reimplement to use s_cos_template.c. * sysdeps/m68k/m680x0/fpu/s_cosf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cosl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1.c: Reimplement to use s_expm1_template.c. * sysdeps/m68k/m680x0/fpu/s_expm1f.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1l.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabs.c: Reimplement to use s_fabs_template.c. * sysdeps/m68k/m680x0/fpu/s_fabsf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabsl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floor.c: Reimplement to use s_floor_template.c. * sysdeps/m68k/m680x0/fpu/s_floorf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floorl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_frexp.c: Reimplement to use s_frexp_template.c. * sysdeps/m68k/m680x0/fpu/s_frexpf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrint.c: Reimplement to use s_lrint_template.c. * sysdeps/m68k/m680x0/fpu/s_lrintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modf.c: Reimplement to use s_modf_template.c. * sysdeps/m68k/m680x0/fpu/s_modff.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modfl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyint.c: Reimplement to use s_nearbyint_template.c. * sysdeps/m68k/m680x0/fpu/s_nearbyintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquo.c: Reimplement to use s_remquo_template.c. * sysdeps/m68k/m680x0/fpu/s_remquof.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquol.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint.c: Reimplement to use s_rint_template.c. * sysdeps/m68k/m680x0/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sin.c: Reimplement to use s_sin_template.c. * sysdeps/m68k/m680x0/fpu/s_sinf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sinl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincos.c: Reimplement to use s_sincos_template.c. * sysdeps/m68k/m680x0/fpu/s_sincosf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincosl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tan.c: Reimplement to use s_tan_template.c. * sysdeps/m68k/m680x0/fpu/s_tanf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanh.c: Reimplement to use s_tanh_template.c. * sysdeps/m68k/m680x0/fpu/s_tanhf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanhl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc.c: Reimplement to use s_trunc_template.c. * sysdeps/m68k/m680x0/fpu/s_truncf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_truncl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_significand.c: Reimplement based on s_atan.c instead of including s_atan.c. * sysdeps/m68k/m680x0/fpu/s_significandf.c: Reimplement based on s_atanf.c instead of including s_atanf.c. * sysdeps/m68k/m680x0/fpu/s_significandl.c: Reimplement based on s_atanl.c instead of including s_atanl.c. * sysdeps/m68k/m680x0/fpu/s_log1p.c: Include s_significand.c instead of s_atan.c. * sysdeps/m68k/m680x0/fpu/s_log1pf.c: Include s_significandf.c instead of s_atanf.c. * sysdeps/m68k/m680x0/fpu/s_log1pl.c: Include s_significandl.c instead of s_atanl.c.

2017-11-30plural.c: improve reproducibilityJuro Bystricky
There is a subtle non-determinism when building glibc. This depends on whether the glibc is built using the distibuted file intl/plural.c or built using the generated file intl/plural.c. These two files (intl/plural.c generated vs. distributed) are slightly different, hence we may end up with slightly different libraries. Originally, having "bison" installed was optional. So if "bison" was not present, we always built libraries with the distributed plural.c. If bison was installed, we *** may have *** replaced the distributed file plural.c with a new plural.c generated from plural.y. if the timestamps triggered this rule: plural.c plural.y $(BISON) $(BISONFLAGS) $@ $^ Given that timestamps are not preserved in GIT repositories, the above rule is not reliable without explicitly touching plural.c or plural.y. In other words, the rule may or may not have fired. In summary: there are two distinct sources of non-determinism: 1. Having "bison" installed or not 2. Having "bison" installed but timestamps poorly defined. This patch fixes this by requiring "bison" being installed and by always generating intl/plural.c from intl/plural.y. (This is achieved by simply removing checked-in intl/plural.c) [BZ #22432] * configure.ac (BISON): Require to be present. * configure: Regenerated. * intl/Makefile (generated): Add plural.c. [$(BISON) != no]: Make code unconditional. (plural.c): Change rule to $(objpfx)plural.c. ($(objpfx)plural.o): Depend on $(objpfx)plural.c. * intl/plural.c: Remove. * manual/install.texi (Tools for Compilation): Document bison as required. * INSTALL: Regenerated.
2017-11-30Use libm_alias macros in m68k llrint functions.Joseph Myers
Most m68k libm functions share code via sources for one function including those for another function or type, in a way that will require significant changes to create function aliases in a way friendly to adding _FloatN / _FloatNx aliases. The llrint function implementations, however, use a conventional separate implementation for each floating-point type. Thus preparing them for _FloatN / _FloatNx aliases is just a matter of changing them to include the appropriate headers and use the appropriate macros, which this patch does. The llrintl changes aren't strictly required, since m68k long double does not meet the criteria for a _FloatN / _FloatNx type, but are included anyway to keep consistency between the implementations for the three types. Tested with build-many-glibcs.py that installed stripped shared libraries for m68k-linux-gnu are unchanged by the patch. * sysdeps/m68k/m680x0/fpu/s_llrint.c: Include <libm-alias-double.h>. (llrint): Define using libm_alias_double. * sysdeps/m68k/m680x0/fpu/s_llrintf.c: Include <libm-alias-float.h>. (llrintf): Define using libm_alias_float. * sysdeps/m68k/m680x0/fpu/s_llrintl.c: Include <libm-alias-ldouble.h>. (llrintl): Define using libm_alias_ldouble.
2017-11-30Use declare_mgen_alias in m68k templates.Joseph Myers
Some m68k libm functions have their own templates replacing the generic math/ ones but using the type-generic template machinery. These currently define function aliases directly using weak_alias. In preparation for additional _FloatN / _FloatNx function aliases, this patch changes them to use declare_mgen_alias for creating aliases instead. Tested with build-many-glibcs.py that installed stripped shared libraries for m68k-linux-gnu are unchanged by the patch. * sysdeps/m68k/m680x0/fpu/s_ccosh_template.c (ccosh): Use declare_mgen_alias instead of weak_alias. * sysdeps/m68k/m680x0/fpu/s_cexp_template.c (cexp): Likewise. * sysdeps/m68k/m680x0/fpu/s_csin_template.c (csin): Likewise. * sysdeps/m68k/m680x0/fpu/s_csinh_template.c (csinh): Likewise.
