* Compile archives with -fno-pie hjl/pr17841/masterH.J. Lu2015-05-285-5/+30
| | | | | | | | | | | | | | | | | | | | | | | When compiler defaults to PIE, we compile archives with -fno-pie. Since archives won't be used with PIE, compile them with -fpie isn't necessary.

* Support compilers defaulting to PIEH.J. Lu2015-05-285-0/+42
| | | | | | | | | | | | | | | | | To support building glibc with GCC 6 configured with --enable-default-pie, which generates PIE by default, we need to build programs as PIE. But elf/tst-dlopen-aout must not be built as PIE since it tests dlopen on ET_EXEC file and PIE is ET_DYN. [BZ #17841] * Makeconfig (no-pie-ldflag): New. (+link): Set to $(+link-pie) if default to PIE. (+link-tests): Set to $(+link-pie-tests) if default to PIE. * config.make.in (build-pie-default): New. * configure.ac (libc_cv_pie_default): New. Set to yes if -fPIE is default. AC_SUBST. * configure: Regenerated. * elf/Makefile (LDFLAGS-tst-dlopen-aout): New.

* tile: use better variable naming in INLINE_SYSCALLChris Metcalf2015-05-262-14/+21
| | | | | | | | | | | | | | | At issue for INLINE_SYSCALL was that it used "err" and "val" as variable names in a #define, so that if it was used in a context where the "caller" was also using "err" or "val", and those variables were passed in to INLINE_SYSCALL, we would end up referencing the internal shadowed variables instead. For example, "char val" in check_may_shrink_heap() in sysdeps/unix/sysv/linux/malloc-sysdep.h was being shadowed by the syscall return "val" in INLINE_SYSCALL, causing the "char val" not to get updated at all, and may_shrink_heap ended up always false. A similar fix was made to INTERNAL_VSYSCALL_CALL.

| | | | | | | | This patch removes the architecture specific gettimeofday implementation to use the vDSO symbol and consolidate it on a common Linux one. Similar to clock_gettime and clock_getres vDSO implementation, each port that supports gettimeofday through vDSO should just implement INLINE_VSYSCALL to access the symbol and define HAVE_{GETTIME,GETRES}_VSYSCAL as 1.
* Fix sorting order for Ukrainian locale (BZ 17293)Andriy Rysin2015-05-265-73/+76
| | | | | | | | | | | | | In the introduction for the official orthography rules for Ukrainian language (http://spelling.ulif.org.ua/peredmova.htm) there's a note that only apostrophe does not affect order of the words when sorting. As could be seen from the official alphabet the soft sign (U+044C/U+042C) has its hard position and thus affects the order and also letters "е" and "є" (CYR-IE: U+0435/U+0415 and UKR-IE: U+0454/U+0404) have their own positions and should have separate place when sorting. This also corresponds to official Unicode collation chart for these letters: http://unicode.org/charts/collation/chart_Cyrillic.html

* Consolidate vDSO macros and usageAdhemerval Zanella2015-05-2627-552/+409
| | | | | | | | | | | | | | | | This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.

* Remove obsolete aliases that broke 'locale -a'Paul Eggert2015-05-223-4/+23
| | | | | | | | | [BZ #18412] * intl/locale.alias: Remove obsolete aliases "bokmål" and "français" which caused 'locale -a' to output Latin-1 data in UTF-8 locales, breaking some applications that use 'locale -a' output. Change the encoding of this file from Latin-1 to ASCII to avoid other potential problems with people grepping this file.
* Remove socket.S implementationAdhemerval Zanella2015-05-2263-1718/+702
| | | | | | | | | | | | | | | This patch removes the socket.S implementation for all ports and replace it by a C implementation using socketcall. For ports that implement the syscall directly, there is no change. The patch idea is to simplify the socket function implementation that uses the socketcall to be based on C implemetation instead of a pseudo assembly implementation with arch specific parts. The patch then remove the assembly implementatation for the ports which uses socketcall (i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh). I have cross-build GLIBC for afore-mentioned ports and tested on both i386 and ppc32 without regressions.
* Fix soft-fp fma for -Wuninitialized.Joseph Myers2015-05-224-0/+43
| | | | | | | | | | | | | | | | | | | | | The soft-fp implementations of fma produce -Wuninitialized warnings because, in the cases where the result is not a nonzero finite value, the soft-fp does not set the exponent of the result since the (cooked) packing will do so, but the compiler does not then see that the exponent is always set in packing before it's used if it wasn't set earlier. This patch uses DIAG_* macros to suppress those warnings. Tested for mips64. (In fact this allows the mips64 build to complete with the -Wno-uninitialized removed from math/Makefile, but more cleanups are still needed in the ldbl-128ibm code for uninitialized warnings there.) * soft-fp/fmadf4.c: Include <libc-internal.h>.

* Fix ldbl-128 / ldbl-128ibm tanl for -Wuninitialized.Joseph Myers2015-05-223-0/+29
| | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of tanl produce uninitialized variable warnings with -Wuninitialized because of a variable that is initialized only conditionally, then used under the same conditions under which it is set. This patch uses DIAG_* macros to suppress those warnings. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/k_tanl.c: Include <libc-internal.h>.

* Fix ldbl-128 / ldbl-128ibm erfcl for -WuninitializedJoseph Myers2015-05-223-2/+6
| | | | | | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of erfcl produce uninitialized variable warnings with -Wuninitialized because of switch statements where in fact one of the cases will always be executed, but the compiler does not see that these cases cover all possibilities (and because the reasoning that it does involves inequalities on the representation of a floating point value leading to a set of possible values for 8.0 times that value, converted to int, it's highly nontrivial for the compiler to see that). This patch fixes those warnings by converting the last case in those switch statements to a "default" case. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/s_erfl.c (__erfcl): Make case 9 in switch statement into default case. * sysdeps/ieee754/ldbl-128ibm/s_erfl.c (__erfcl): Likewise.
* Fix ldbl-128 / ldbl-128ibm asinl for -Wuninitialized.Joseph Myers2015-05-223-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of asinl produce uninitialized variable warnings with -Wuninitialized because the code for small arguments in fact always returns but the compiler cannot see this and instead sees that a variable would be uninitialized if the "if (huge + x > one)" conditional used to force the "inexact" exception were false. All the code in libm trying to force "inexact" for functions that are not exactly defined is suspect and should be removed at some point given that we now have a clear definition of the accuracy goals for libm functions which, following C99/C11, does not require anything about "inexact" for most functions (likewise, the multi-precision code that tries to give correctly-rounded results, very slowly, for functions for which the goals clearly do not include correct rounding, if the faster paths are accurate enough). However, for now this patch simply changes the code to use math_force_eval, rather than "if", to ensure the evaluation of the inexact computation. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/e_asinl.c (__ieee754_asinl): Don't use a conditional in forcing "inexact". * sysdeps/ieee754/ldbl-128ibm/e_asinl.c (__ieee754_asinl): Likewise.

* Restore _POSIX2_C_VERSION definition (bug 438).Joseph Myers2015-05-224-11/+19
| | | | | | | | | | | | | | | | | | | My review of conformtest expectations for POSIX showed up that the _POSIX2_C_VERSION macro, required by POSIX and XPG standards before 2001, was missing in unistd.h, having been removed on 2003-04-03 despite those standards still being supported. This patch adds it back. As it's in the implementation namespace, there's no need for it to be conditional, and other such macros aren't conditional in this header either. Tested for x86_64 and x86 (testsuite). Note that this *does* change the installed libraries, because it affects the sysconf support (present all along) for _SC_2_C_VERSION. [BZ #438] * posix/unistd.h (_POSIX2_C_VERSION): New macro. * conform/Makefile (test-xfail-POSIX/unistd.h/conform): Remove variable.

| | | | | | | | | | | | | | | | | | | | | pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename. But pathconf is in POSIX back to 1990 while basename is only reserved with external linkage in those standards including XPG functions. This patch fixes this namespace issue in the usual way, renaming basename to __basename and making it into a weak alias. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18444] * string/basename.c (basename): Rename to __basename and define as weak alias of __basename. Use libc_hidden_weak. * include/string.h (__basename): Declare.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you remove the "override CFLAGS += -Wno-uninitialized" in math/Makefile, you get errors from lgamma implementations of the form: ../sysdeps/ieee754/dbl-64/e_lgamma_r.c: In function '__ieee754_lgamma_r': ../sysdeps/ieee754/dbl-64/e_lgamma_r.c:297:13: error: 'nadj' may be used uninitialized in this function [-Werror=maybe-uninitialized] if(hx<0) r = nadj - r; This is one of the standard kinds of false positive uninitialized warnings: nadj is set under a certain condition, and then later used under the same condition. This patch uses DIAG_* macros to suppress the warning on the use of nadj. The ldbl-128 / ldbl-128ibm implementation has a substantially different structure that avoids this issue. Tested for x86_64. (In fact this patch eliminates the need for that -Wno-uninitialized on x86_64, but I want to test on more architectures before removing it.) * sysdeps/ieee754/dbl-64/e_lgamma_r.c: Include <libc-internal.h>.

| | | | | | | | | | | | | | | | | | | | If you remove the "override CFLAGS += -Wno-uninitialized" in math/Makefile, one of the errors you get is: ../sysdeps/ieee754/dbl-64/mpa.c: In function '__mp_dbl.part.0': ../sysdeps/ieee754/dbl-64/mpa.c:183:5: error: 'c' may be used uninitialized in this function [-Werror=maybe-uninitialized] c *= X[0]; The problem is that the p < 5 case initializes c if p is 1, 2, 3 or 4 but not otherwise, and in fact p is positive for all calls to this function so the uninitialized case can't actually occur. This patch replaces the "if (p == 4)" last case with a comment so the compiler can see that all paths do initialize c.

* Fix ldbl-96 remquol (finite, Inf) (bug 18244).Joseph Myers2015-05-194-3/+46
| | | | | | | | | | | | | | | | | | ldbl-96 remquol wrongly handles the case where the first argument is finite and the second infinite, because the check for the second argument being a NaN fails to disregard the explicit high mantissa bit and so wrongly interprets an infinity as being a NaN. This patch fixes this by masking off that bit, and improves test coverage for both remainder and remquo (various cases were missing tests, or, as in the case of the bug, were tested only for one of the two functions). Tested for x86_64 and x86. [BZ #18244] * sysdeps/ieee754/ldbl-96/s_remquol.c (__remquol): Ignore explicit high mantissa bit when testing whether P is a NaN. * math/libm-test.inc (remainder_test_data): Add more tests. (remquo_test_data): Likewise.
* Fix i386 atanhl spurious underflows (bug 18049).Joseph Myers2015-05-195-4/+352
| | | | | | | | | | | | | | | | The i386 implementation of atanhl, for small arguments, does a calculation that involves computing twice the square of the argument, resulting in spurious underflows for some arguments. This patch fixes this by just returning the argument when its exponent is below -32, with underflow being forced as needed for subnormal arguments. Tested for x86 and x86_64. [BZ #18049] * sysdeps/i386/fpu/e_atanhl.S (__ieee754_atanhl): For exponents below -32, return the argument, with underflow if subnormal. * math/auto-libm-test-in: Add more tests of atanh. * math/auto-libm-test-out: Regenerated.

| | | | | | [BZ #17581] The checking chain of unused chunks was terminated by a hash of the block pointer, which was sometimes confused with the chunk length byte. We now avoid using a length byte equal to the magic byte.
