* Fix namespace conformance issue with Bessel functions.Chris Metcalf2014-12-224-6/+12
| | | | | | | | | [BZ #17747] The y0/y1/yn and j0/j1/jn functions provided a strong_alias to the "l"-suffixed variants when no long double support is being compiled. This breaks namespace conformance when the basename versions conform but the l-suffixed ones don't. Fixed by making them weak aliases instead.
* tilegx: remove implicit boolean conversion in strstr.Chris Metcalf2014-12-223-2/+8
| | | | | | | | [BZ #17746] The __builtin_expect() truncated a uint64_t to a 32-bit long in ILP32 mode, discarding the high 32 bits, and potentially missing the NUL terminator that we were searching for with SIMD operations. Explicitly compare to zero to fix the problem.

* Split __kernel_standard* functions (fixes bug 17724).Joseph Myers2014-12-226-93/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 17724 reports references to fesetround being brought in by ldbl-128ibm rintl via references to __rintl from __kernel_standard_l. Because all three __kernel_standard* functions are in the same file, this gets brought in even though only the long double version __kernel_standard_l needs __rintl, and the C90 functions use only __kernel_standard. This patch fixes this by splitting the three versions into separate files; it's fine for long double functions to refer to fe* functions directly, unless they get called by C90 double functions. Tested for x86_64 (testsuite; the reordering of code means disassembly of shared libraries can't usefully be compared). Tested for powerpc that the relevant issue disappears from the linknamespace test output. [BZ #17724] * sysdeps/ieee754/k_standard.c: Don't include <float.h>. (__kernel_standard_f): Remove. Moved to k_standardf.c. (__kernel_standard_l): Remove. Moved to k_standardl.c with (char *) casts added. * sysdeps/ieee754/k_standardf.c: New file. * sysdeps/ieee754/k_standardl.c: Likewise. * math/Makefile (libm-support): Remove k_standard.

* Fix resolver bind, getsockname namespace (bug 17733).Joseph Myers2014-12-224-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | On Linux architectures using socketcall, the resolver ends up bringing in strong symbols for bind and getsockname, which are not in POSIX.1-1996. This causes linknamespace test failures: FAIL: conform/POSIX/pthread.h/linknamespace FAIL: conform/POSIX/sched.h/linknamespace FAIL: conform/POSIX/time.h/linknamespace These functions are defined as strong symbols with __bind and __getsockname as weak aliases. This patch switches this to the other way round by removing the NO_WEAK_ALIAS definitions and so letting the default case in socket.S act; I see no reason for the existing arrangements. Tested for x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17733] * sysdeps/unix/sysv/linux/bind.S (NO_WEAK_ALIAS): Do not define. (__bind): Do not define as weak alias. * sysdeps/unix/sysv/linux/getsockname.S (NO_WEAK_ALIAS): Do not define. (__getsockname): Do not define as weak alias.
* Require bison 2.7 or newer for regenerating intl/plural.yWill Newton2014-12-225-17/+65
| | | | | | | | | | | | | | | | | | | The merge of the latest gettext code introduced changes to the yacc parser source that are incompatible with versions of bison older than 2.7. Add a configure check for the appropriate versions and document the requirement in INSTALL. ChangeLog: 2014-12-22 Will Newton <will.newton@linaro.org> * manual/install.texi: Document that we require bison 2.7 or above. * INSTALL: Regenerate. * configure.ac: Use AC_CHECK_PROG_VER instead of AC_PATH_PROG when checking for bison and check for version 2.7 or above. * configure: Regenerate.

* Add hidden __tls_get_addr/___tls_get_addr aliasH.J. Lu2014-12-217-15/+34
| | | | | | | | | | | | | | | | | | | | __tls_get_addr/___tls_get_addr is always defined in ld.so. There is no need to call them via PLT inside ld.so. This patch adds the hidden __tls_get_addr/___tls_get_addr aliases and calls them directly from _dl_tlsdesc_dynamic. There is no need to set up the EBX register in i386 _dl_tlsdesc_dynamic when calling the hidden ___tls_get_addr. * elf/dl-tls.c (__tls_get_addr): Provide the hidden definition if not defined. * sysdeps/i386/dl-tls.h (___tls_get_addr): Provide the hidden definition. * sysdeps/i386/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Call the hidden ___tls_get_addr. * sysdeps/x86_64/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Call the hidden __tls_get_addr. * sysdeps/generic/localplt.data (__tls_get_addr): Removed. * sysdeps/unix/sysv/linux/i386/localplt.data (___tls_get_addr): Likewise.

* Compile s_llround.c with -Wno-error for x32 buildH.J. Lu2014-12-192-0/+10
| | | | | | Since x32 returns 32-bit long int and 64-bit long long int in the same 64-bit register, we make the 32b-bit lround an alias of the 64-bit llround. Add -Wno-error for x32 build to silence the compiler.
* Replace 1L with (mp_limb_t) 1H.J. Lu2014-12-192-1/+6
| | | | | | | | | | | | | | | X86-64 and x32 use sysdeps/i386/ldbl2mpn.c. res_ptr is a pointer to mp_limb_t, which is long for i386 and x86-64 and long long for x32. On x32, I got ../sysdeps/x86_64/../i386/ldbl2mpn.c: In function ‘__mpn_extract_long_double’: ../sysdeps/x86_64/../i386/ldbl2mpn.c:72:4: error: left shift count >= width of type [-Werror] res_ptr[N - 1] &= ~(1L << ((LDBL_MANT_DIG - 1) % BITS_PER_MP_LIMB)); ^ cc1: all warnings being treated as errors This patch replaces 1L with (mp_limb_t) 1. Verified on x32, i686 and x86-64 with GCC 4.8.3.

* Fix profil_counter namespace (bug 17725).Joseph Myers2014-12-1716-21/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM, where profil_counter is not static, it is brought in by references to various standard functions, as noted in <https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although it is not a standard function itself. I don't know if this also causes test failures on SPARC, although I see no reason for it not to do so. This patch fixes this namespace issue. profil_counter is renamed to __profil_counter and made a weak alias on ARM and SPARC. Because of the uses in profil.c / sprofil.c it seems simplest to make the rename globally, including on the other architectures for which profil_counter was static and so the change is of no substance. The variant names profil_counter_* used in sprofil.c are also renamed to start with __ so that undesired function names do not get exported in static libc. As I noted in bug 17726, profil_counter should probably be a compat symbol on ARM and SPARC, so it wouldn't exist at all in static libc even as a weak alias. Since defining a compat symbol still requires an internal name as a target of an alias, this patch still seems reasonable as an intermediate step towards that goal: it wouldn't be possible for the function simply to be static profil_counter on ARM and SPARC with profil_counter also being the exported compat symbol name, so profil.c / sprofil.c would still need to be prepared to call the function under another name (here, __profil_counter). Tested for x86_64 (testsuite, and that stripped installed shared libraries are unchanged by the patch) and ARM (ABI and linknamespace tests - this patch reduces the number of linknamespace failures I see on ARM from 227 to 5, the residue being math.h failures for fe* functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases). 2014-12-17 Joseph Myers <joseph@codesourcery.com> [BZ #17725] * sysdeps/generic/profil-counter.h (profil_counter): Rename to __profil_counter. * sysdeps/unix/sysv/linux/hppa/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/i386/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/ia64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/sh/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/tile/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/x86_64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Likewise.

* Fix resolver inet_* namespace (bug 17722).Joseph Myers2014-12-178-12/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parts of the resolver brought in by pthreads (at least) use inet_* functions that aren't in the 1995/6 edition of POSIX that introduced pthreads (or in one case, use __inet_aton which is then defined in the same file as non-weak inet_addr). This patch fixes this by making the affected functions into weak alias for __inet_* and using those names in the problematic resolver code.
