2015-04-28Fix ldbl-128 roundl for exponents in [31, 47] (bug 18346).Joseph Myers1-1/+1
The implementation of roundl for ldbl-128 involves undefined behavior for arguments with exponents from 31 to 47 inclusive, from the shift: u_int64_t i = -1ULL >> (j0 - 48); For example, on mips64, this means roundl (0xffffffffffff.8p0L) wrongly returns its argument, which is not an integer. A condition checking for exponents < 31 should actually be checking for exponents < 48, and this patch makes it do so. (That condition is for whether the bit representing 0.5 is in the high 64-bit half of the floating-point number. The value 31 might have arisen from an incorrect conversion of the ldbl-96 version to handle ldbl-128.) This was originally reported as a GCC libquadmath bug <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65757>. Tested for mips64; also tested for x86_64 and x86 to make sure the new tests pass there. [BZ #18346] * sysdeps/ieee754/ldbl-128/s_roundl.c (__roundl): Handle all exponents less than 48 as cases where high part of mantissa needs examining to determine whether argument is integral. * math/libm-test.inc (round_test_data): Add more tests.

2015-04-24S/390: Get cache information via sysconfStefan Liebler1-0/+230
This patch adds support to query cache information on s390 via sysconf() function - e.g. with _SC_LEVEL1_ICACHE_SIZE. The attributes size, linesize and assoc can be queried for cache level 1 - 4 via "extract cpu attribute" instruction, which was first available with z10. * NEWS: Mention sysconf() cache information support for s390. * sysdeps/unix/sysv/linux/s390/sysconf.c: New File.

2015-04-16tile: Enable PI_STATIC_AND_HIDDENChris Metcalf2-0/+13
This does make ld.so very slightly larger (0.3%) and doesn't seem to actually improve performance; in fact, my limited testing suggested a slight (0.1%) performance decrease (running fork/exec of a no-op program in a loop), but I didn't do enough testing to establish statistical significance. However, Roland agrees that it makes sense to switch tile to using this path, since it's the more standard way.
2015-04-15powerpc: Fix __wcschr static buildAdhemerval Zanella2-6/+22
This patch fix the static build for strftime, which uses __wcschr. Current powerpc32 implementation defines the __wcschr be an alias to __wcschr_ppc32 and current implementation misses the correct alias for static build. It also changes the default wcschr.c logic so a IFUNC implementation should just define WCSCHR and undefine the required alias/internal definitions.

2015-04-13Set errno for log1p on pole/domain error.Stefan Liebler17-17/+112
According to bug 6792, errno is not set to ERANGE/EDOM by calling log1p/log1pf/log1pl with x = -1 or x < -1. This patch adds a wrapper which sets errno in those cases and returns the value of the existing __log1p function. The log1p is now an alias to the wrapper function instead of __log1p. The files in sysdeps are reflecting these changes. The ia64 implementation sets errno by itself, thus the wrapper-file is empty. The libm-test is adjusted for log1p-tests to check errno.

2015-04-08Fix dbl-64 atan2 in non-default rounding modes (bug 18210, bug 18211).Joseph Myers3-36/+46
The dbl-64 implementation of atan2 does computations that expect to run in round-to-nearest mode, and in other modes the errors can accumulate to more than the maximum accepted 9ulp. This patch makes it use FE_TONEAREST internally, similar to other functions with such issues. Tests that previously produced large errors are added for atan2 and the closely related carg, clog and clog10 functions. Tested for x86_64 and x86 and ulps updated accordingly. [BZ #18210] [BZ #18211] * sysdeps/ieee754/dbl-64/e_atan2.c: Include <fenv.h>.

Silvermont and Knights Landing have a modular system design with two cores sharing an L2 cache. If more than 2 cores are detected to shared L2 cache, it should be adjusted for Silvermont and Knights Landing. [BZ #18185] * sysdeps/x86_64/cacheinfo.c (init_cacheinfo): Limit threads sharing L2 cache to 2 for Silvermont/Knights Landing.
2015-03-31Add ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA to x86H.J. Lu5-5/+31
With copy relocation, address of protected data defined in the shared library may be external. When there is a relocation against the protected data symbol within the shared library, we need to check if we should skip the definition in the executable copied from the protected data. This patch adds ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA and defines it for x86. If ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA isn't 0, do_lookup_x will skip the data definition in the executable from copy reloc. [BZ #17711] * elf/dl-lookup.c (do_lookup_x): When UNDEF_MAP is NULL, which indicates it is called from do_lookup_x on relocation against protected data, skip the data definion in the executable from copy reloc. (_dl_lookup_symbol_x): Pass ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA, instead of ELF_RTYPE_CLASS_PLT, to do_lookup_x for EXTERN_PROTECTED_DATA relocation against STT_OBJECT symbol. * sysdeps/generic/ldsodefs.h * (ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA): New. Defined to 4 if DL_EXTERN_PROTECTED_DATA is defined, otherwise to 0. * sysdeps/i386/dl-lookupcfg.h (DL_EXTERN_PROTECTED_DATA): New. * sysdeps/i386/dl-machine.h (elf_machine_type_class): Set class to ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for R_386_GLOB_DAT. * sysdeps/x86_64/dl-lookupcfg.h (DL_EXTERN_PROTECTED_DATA): New. * sysdeps/x86_64/dl-machine.h (elf_machine_type_class): Set class to ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for R_X86_64_GLOB_DAT.
2015-03-28NPTL: Remove duplicate definition of PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NPMartin Galvan1-2/+0
The PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NP macro was defined twice with the same values in pthread.h; this removes the second definition.
2015-03-28NPTL: swap comments for THREAD_SETMEM and THREAD_SETMEM_NC for i386 and x86_64Martin Galvan2-4/+5
The comments for THREAD_SETMEM and THREAD_SETMEM_NC were swapped for i386 and x86_64; this patch fixes that.
2015-03-26Harden powerpc64 elf_machine_fixup_pltAlan Modra1-5/+25
IFUNC is difficult to correctly implement on any target needing a GOT to support position independent code, due to the dependency on order of dynamic relocations. ld.so should be changed to apply IFUNC relocations last, globally, because without that it is actually impossible to write an IFUNC resolver in C that works in all situations. Case in point, vfork in libpthread.so is an IFUNC with the resolver returning &__libc_vfork. (system and fork are similar.) If another shared library, libA say, uses vfork then it is quite possible that libpthread.so hasn't been dynamically relocated before the unfortunate libA is dynamically relocated. In that case the GOT entry for &__libc_vfork is still zero, so the IFUNC resolver returns NULL. LD_BIND_NOW=1 results in libA PLT dynamic relocations being applied using this NULL value and ld.so segfaults. This patch hardens ld.so to not segfault on a NULL from an IFUNC resolver. It also fixes a problem with undefined weak. If you leave the plt entry as-is for undefined weak then if the entry is ever called it will loop in ld.so rather than segfaulting. * sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_fixup_plt): Don't segfault if ifunc resolver returns a NULL. Do set plt to zero for undefined weak. (elf_machine_plt_conflict): Similarly.

2015-03-25Support six-argument syscalls from C for 32-bit x86, use generic ↵Joseph Myers5-153/+106
lowlevellock-futex.h (bug 18138). This patch follows the approach outlined in <https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86, making them call a function __libc_do_syscall that takes the syscall number and three syscall arguments in the registers in which the kernel expects them, along with a pointer to a structure containing the other three arguments. In turn, this allows the generic lowlevellock-futex.h to be used on 32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138 for 32-bit x86 and leaving hppa as the only architecture missing lll_futex_timed_wait_bitset). The change to lowlevellock.h's definition of SYS_futex is because the generic lowlevelloc-futex.h ends up bringing in bits/syscall.h which defines SYS_futex to __NR_futex, so resulting in redefinition errors. The revised definition in lowlevellock.h is in line with what the x86_64 version does. __libc_do_syscall is only needed in libpthread at present (meaning nothing special needs to be done to make it shared-only in most libraries containing it, static in libc only, as on ARM). Tested for 32-bit x86, with the glibc testsuite and with the test in bug 18138. The failures seen FAIL: nptl/tst-cleanupx4 FAIL: rt/tst-cpuclock2 are pre-existing.
