* 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.
* tile: separate ffsll from ffsChris Metcalf2014-12-213-11/+36
| | | | | This avoids a linknamespace failure when ffs is legal but ffsll is not.
* tile: remove localplt.data and use generic one again.Chris Metcalf2014-12-212-18/+4
| | | | With the __tls_get_addr removed, it works for tile.
* 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.

* manual: Correct guarantee about pointers compared by qsort()Anders Kaseorg2014-12-212-6/+13

* tilegx: fix strstr to build and link betterChris Metcalf2014-12-192-1/+7
| | | | | | | | The two_way_short_needle() routine included from str-two-way.h is not used, so mark it so to avoid compiler warnings. Calling strnlen() breaks linknamespace tests, so change it to __strnlen().

| | | | | We rewrite strncat to use strnlen and malloc calls which simplifies code an is faster as these functions are better optimized than original code.

* 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. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

* Fix x86_64 memrchr namespace (bug 17719).Joseph Myers2014-12-164-8/+14
| | | | | | | | | | | | | | | | | | | | | | | On x86_64, memrchr (not a standard function) is defined as a strong symbol, instead of a weak alias of __memrchr as on other architectures. This results in linknamespace test failures from the use of __memrchr from dirname. (Not a conformance issue because of the mem* reservation, but contrary to glibc conventions.) This patch makes x86_64 follow other architectures by defining memrchr as a weak alias. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17719] * sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and define as weak alias of __memrchr.
