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). Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged for all its hard-float powerpc configurations. * sysdeps/powerpc/power7/fpu/s_logb.c: Include <libm-alias-double.h>.

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.
2017-12-01Ues libm_alias_double for various powerpc functions.Joseph Myers
Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch various powerpc functions use libm_alias_double to define function aliases (with consequent removal of the need for local compat symbol handling). (The present patch excludes the changes to some functions where such changes could result in differences in installed stripped shared libraries because of changes to the exact ordering or properties of symbols in individual .os files.)

2017-12-01Use libm_alias_double for powerpc fabs, fma.Joseph Myers
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). Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged for all its hard-float powerpc configurations. * sysdeps/powerpc/fpu/s_fabs.S: Include <libm-alias-double.h>.

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>.

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.

2017-11-30x86: Make a space in jmpbuf for shadow stack pointerH.J. Lu
To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement Technology (CET) in setjmp/longjmp, we need to save shadow stack pointer in jmp_buf. The __saved_mask field in jmp_buf has type of __sigset_t. On Linux, __sigset_t is defined as #define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int))) typedef struct { unsigned long int __val[_SIGSET_NWORDS]; } __sigset_t; which is much bigger than expected by the __sigprocmask system call, which has typedef struct { unsigned long sig[_NSIG_WORDS]; } sigset_t; For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf to add paddings for shadow stack pointer. As long as the new __sigset_t is not smaller than sigset_t expected by the __sigprocmask system call, it should work correctly. This patch adds an internal header file, <setjmpP.h>, to define __jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a space to store shadow stack pointer. It verifies __jmp_buf_sigset_t has the suitable size for the __sigprocmask system call. A run-time test, tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t is sufficient. If its size is too small, the test fails with rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc 0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address) rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc 0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address) rt_sigprocmask(SIG_SETMASK, NULL, 0x7fa8aa28effc, 8) = -1 EFAULT (Bad address) exit_group(1) = ?

2017-11-30Fix integer overflow in malloc when tcache is enabled [BZ #22375]Arjun Shankar
When the per-thread cache is enabled, __libc_malloc uses request2size (which does not perform an overflow check) to calculate the chunk size from the requested allocation size. This leads to an integer overflow causing malloc to incorrectly return the last successfully allocated block when called with a very large size argument (close to SIZE_MAX). This commit uses checked_request2size instead, removing the overflow.
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.

2017-11-29Use libm_alias_double for sparc.Joseph Myers
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 simplification where compat symbol handling is now done by those macros rather than locally in architecture-specific code).

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>. (fabsl): Define as compat symbol at version GLIBC_2_0 for libm.
2017-11-29Add SPARC --disable-multi-arch builds to build-many-glibcs.py.Joseph Myers
While working on SPARC changes to use libm_alias_* I noticed that the non-multi-arch sparc32/sparcv9/fpu/s_fabs.S was missing compat symbol support for fabsl. This clearly shows inadequate test coverage, so this patch adds SPARC --disable-multi-arch builds to build-many-glibcs.py (the 32-bit one fails testing until that bug is fixed, the 64-bit one passes testing). * scripts/build-many-glibcs.py (Context.add_all_configs): Add SPARC --disable-multi-arch glibc variants.
