* i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120] hjl/pr21120/masterH.J. Lu2017-06-304-10/+56
| | | | | | | | | | | | | | | | | | | | | | | GCC 7 changed the definition of max_align_t on i386: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2 As a result, glibc malloc no longer returns memory blocks which are as aligned as max_align_t requires. This causes malloc/tst-malloc-thread-fail to fail with an error like this one: error: allocation function 0, size 144 not aligned to 16 This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h> and increases the malloc alignment to 16 for i386. [BZ #21120] * malloc/malloc-internal.h (MALLOC_ALIGNMENT): Moved to ... * sysdeps/generic/malloc-alignment.h: Here. New file. * sysdeps/i386/malloc-alignment.h: Likewise. * sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

* posix: Improve default posix_spawn implementationAdhemerval Zanella2017-06-292-183/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the default posix implementation of posix_spawn{p} and align with Linux one. The main idea is to fix some issues already fixed in Linux code, and deprecated vfork internal usage (source of various bug reports). In a short: - It moves POSIX_SPAWN_USEVFORK usage and sets it a no-op. Since the process that actually spawn the new process do not share memory with parent (with vfork), it fixes BZ#14750 for this implementation. - It uses a pipe to correctly obtain the return upon failure of execution (BZ#18433). - It correctly enable/disable asynchronous cancellation (checked on ptl/tst-exec5.c). - It correctly disable/enable signal handling. Using this version instead of Linux shows only one regression, posix/tst-spawn3, because of pipe2 usage which increase total number of file descriptor. * sysdeps/posix/spawni.c (__spawni_child): New function. (__spawni): Rename to __spawnix.

* Support _Float128 in tgmath.h.Joseph Myers2017-06-284-40/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds tgmath.h support for _Float128, so eliminating the awkward caveat in NEWS about the type not being supported there. This does inevitably increase the size of macro expansions (which grows particularly fast when you have nested calls to tgmath.h macros), but only when _Float128 is supported and the declarations of _Float128 interfaces are visible; otherwise the expansions are unchanged. Tested for x86_64 and arm. * math/tgmath.h: Include <bits/libc-header-start.h> and <bits/floatn.h>. (__TGMATH_F128): New macro. (__TGMATH_CF128): Likewise. (__TGMATH_UNARY_REAL_ONLY): Use __TGMATH_F128. (__TGMATH_UNARY_REAL_RET_ONLY): Likewise. (__TGMATH_BINARY_FIRST_REAL_ONLY): Likewise. (__TGMATH_BINARY_FIRST_REAL_STD_ONLY): New macro.

* Use clog10 not __clog10 in tgmath.h log10 macro.Joseph Myers2017-06-283-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | As a GNU extension, for _GNU_SOURCE glibc's complex.h provides a clog10 function and tgmath.h supports complex arguments to the log10 macro. However, tgmath.h uses __clog10 not clog10 in defining the macro. There is no namespace reason (ignoring the block-scope namespace issues that would apply equally to *every* function called by tgmath.h macros) for using __clog10 here, since this is only for _GNU_SOURCE so clog10 is always visible when this macro definition is used. Furthermore, __clog10f128 is not exported, so supporting _Float128 in tgmath.h implies using clog10 not __clog10 there. (__clog10 and clog10 aren't used in libstdc++ either, although that library would have a good case for using the __clog10 reserved-namespace export: the standard C++ library includes log10 of a complex number.) This patch duly changes the header to use clog10, and enables tests of the macro for complex arguments. Tested for x86_64. * math/tgmath.h [__USE_GNU] (log10): Use clog10 not __clog10. * math/gen-tgmath-tests.py (Tests.add_all_tests): Test log10 for complex arguments.
* Fix tgmath.h totalorder, totalordermag return type (bug 21687).Joseph Myers2017-06-284-9/+31
| | | | | | | | | | | | | | | | | | | The tgmath.h totalorder and totalordermag macros wrongly return a floating-point type. They should return int, like the underlying functions. This patch fixes them accordingly, updating tests including enabling tests of those functions from gen-tgmath-tests.py. Tested for x86_64. [BZ #21687] * math/tgmath.h (__TGMATH_BINARY_REAL_RET_ONLY): New macro. (totalorder): Use it. (totalordermag): Likewise. * math/gen-tgmath-tests.py (Tests.add_all_tests): Enable tests of totalorder and totalordermag. * math/test-tgmath.c (F(compile_test)): Do not call totalorder or totalordermag in arguments of calls to those functions. (NCALLS): Change to 134.
* Simplify tgmath.h for integer return types.Joseph Myers2017-06-282-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | The tgmath.h macros for function with integer return types generate unnecessary casts to the return type. Since in those cases the return type does not depend on the argument type, all the cases in the conditional expressions already have the right type, and no casts are needed; this patch removes them. Tested for x86_64. * math/tgmath.h (__TGMATH_UNARY_REAL_RET_ONLY): Do not take or cast to return type argument. (__TGMATH_TERNARY_FIRST_REAL_RET_ONLY): Likewise. (lrint): Update call to __TGMATH_UNARY_REAL_RET_ONLY. (llrint): Likewise. (lround): Likewise. (llround): Likewise. (ilogb): Likewise. (llogb): Likewise.

* Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).Joseph Myers2017-06-2818-48/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are no longer effective. For most this is harmless - they were only present because of long double functions not being declared with _LIBC defined, and _LIBC is no longer defined for building most tests. For the few where this is actually relevant to the test, testing LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the test to public APIs. This patch fixes the tests accordingly. Tested for x86_64 and arm. [BZ #21607] * math/basic-test.c [!NO_LONG_DOUBLE]: Change conditionals to [LDBL_MANT_DIG > DBL_MANT_DIG]. * math/bug-nextafter.c [!NO_LONG_DOUBLE]: Remove conditionals. * math/bug-nexttoward.c [!NO_LONG_DOUBLE]: Likewise. * math/test-math-isinff.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-math-iszero.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-overflow.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-payload.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except-2.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except.c [!NO_LONG_DOUBLE]: Likewise. * math/test-powl.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite-c99.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-main.c [!NO_LONG_DOUBLE]: Likewise. * math/test-snan.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath-ret.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath.c: Include <float.h>.

* Add more thorough generated tgmath.h test.Joseph Myers2017-06-283-0/+623
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a more thorough test of tgmath.h macros, verifying both the return type and the function called for all the cases of valid argument types. (Cases with current problems - I've just filed four bugs - are disabled or omitted pending fixing those problems.) The test uses a Python generator (works with both Python 2 and 3) to generate a C file which is then built and run as a test in the usual way (and that C file includes its own dummy definitions of libm functions similar to existing tgmath.h tests). The motivation is to make it easier to add tests of tgmath.h for _Float128 when adding tgmath.h support for that type; the _FloatN / _FloatNx support is present in the script, but disabled until the tgmath.h support is written. Tested for x86_64, and for arm to check things in the long double = double case. (In that case, it's OK to call either double or long double functions when the selected type is double or long double, as long as the return type of the macro is exactly correct.) * math/gen-tgmath-tests.py: New file. * math/Makefile [PYTHON] (tests): Add test-tgmath3. [PYTHON] (generated): Add test-tgmath3.c. [PYTHON] (CFLAGS-test-tgmath3.c): New variable. [PYTHON] ($(objpfx)test-tgmath3.c): New rule.
* Require binutils 2.25 or later to build glibc.Joseph Myers2017-06-2810-145/+20
| | | | | | | | | | | | | | | | | | | | | | | This patch implements a requirement of binutils >= 2.25 (up from 2.22) to build glibc. Tests for 2.24 or later on x86_64 and s390 are removed. It was already the case, as indicated by buildbot results, that 2.24 was too old for building tests for 32-bit x86 (produced internal linker errors linking elf/tst-gnu2-tls1mod.so). I don't know if any configure tests for binutils features are obsolete given the increased version requirement. Tested for x86_64. * configure.ac (AS): Require binutils 2.25 or later. (LD): Likewise. * configure: Regenerated. * sysdeps/s390/configure.ac (AS): Remove version check. * sysdeps/s390/configure: Regenerated. * sysdeps/x86_64/configure.ac (AS): Remove version check. * sysdeps/x86_64/configure: Regenerated. * manual/install.texi (Tools for Compilation): Document requirement for binutils 2.25 or later. * INSTALL: Regenerated.

* Miscellaneous sys/ucontext.h namespace fixes (bug 21457).Joseph Myers2017-06-286-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes various miscellaneous namespace issues in sys/ucontext.h headers. Some struct tags are removed where the structs also have *_t typedef names, while other struct tags without such names are renamed to start __; the changes are noted in NEWS as they can affect C++ name mangling (although there seems to be little if any external use of these types, at least based on checking codesearch.debian.net). For powerpc, pointers to struct pt_regs (not defined in this header) are changed to point to struct __ctx(pt_regs), so in the __USE_MISC case those struct fields continue to point to the existing struct pt_regs type for maximum compatibility, while when that's a namespace issue they point to a struct __pt_regs type which is always an incomplete struct. Tested for affected architectures with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h (fpregset_t): Remove struct tag. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h (fpregset_t): Likewise. * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h (mcontext_t): Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (pt_regs): Declare struct type with __ctx. [__WORDSIZE != 32] (mcontext_t): Use __ctx with pt_regs struct tag. (ucontext_t) [__WORDSIZE == 32]: Use __ctx with pt_regs struct tag and regs field name.
* Fix elf/loadtest.c build with GCC 8.Joseph Myers2017-06-272-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Building the testsuite with current GCC mainline fails with: loadtest.c: In function 'main': loadtest.c:76:3: error: macro expands to multiple statements [-Werror=multistatement-macros] for (map = MAPS; map != NULL; map = map->l_next) \ ^ loadtest.c:165:2: note: in expansion of macro 'OUT' OUT; ^~~ loadtest.c:164:7: note: some parts of macro expansion are not guarded by this 'if' clause if (debug) ^~ This seems like a genuine bug, although fairly harmless; it means the fflush call in the OUT macro is unconditional instead of being inside the conditional as presumably intended. This patch makes this macro use do { } while (0) to avoid the problem. Tested for x86_64 (testsuite), and with build-many-glibcs.py for aarch64-linux-gnu with GCC mainline. * elf/loadtest.c (OUT): Define using do { } while (0).
* Fix strftime build with GCC 8.Joseph Myers2017-06-272-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building with current GCC mainline fails with: strftime_l.c: In function '__strftime_internal': strftime_l.c:719:4: error: macro expands to multiple statements [-Werror=multistatement-macros] digits = d > width ? d : width; \ ^ strftime_l.c:1260:6: note: in expansion of macro 'DO_NUMBER' DO_NUMBER (1, tp->tm_year + TM_YEAR_BASE); ^~~~~~~~~ strftime_l.c:1259:4: note: some parts of macro expansion are not guarded by this 'else' clause else ^~~~ In fact this particular instance is harmless; the code looks like: if (modifier == L_('O')) goto bad_format; else DO_NUMBER (1, tp->tm_year + TM_YEAR_BASE); and because of the goto, it doesn't matter that part of the expansion isn't under the "else" conditional. But it's also clearly bad style to rely on that. This patch changes DO_NUMBER and DO_NUMBER_SPACEPAD to use do { } while (0) to avoid such problems. Tested (full testsuite) for x86_64 (GCC 6), and with build-many-glibcs.py with GCC mainline, in conjunction with my libgcc patch <https://gcc.gnu.org/ml/gcc-patches/2017-06/msg02032.html>. * time/strftime_l.c (DO_NUMBER): Define using do { } while (0). (DO_NUMBER_SPACEPAD): Likewise.
* [ARM] Optimise memchr for NEON-enabled processorsPrakhar Bahuguna2017-06-276-1/+304
| | | | | | | | | | | | | | | | | | | | | | | This patch provides an optimised implementation of memchr using NEON instructions to improve its performance, especially with longer search regions. This gave an improvement in performance against the Thumb2+DSP optimised code, with more significant gains for larger inputs. The NEON code also wins in cases where the input is small (less than 8 bytes) by defaulting to a simple byte-by-byte search. This avoids the overhead imposed by filling two quadword registers from memory. * sysdeps/arm/armv7/multiarch/Makefile: Add memchr_neon to sysdep_routines. * sysdeps/arm/armv7/multiarch/ifunc-impl-list.c: Add define for __memchr_neon. Add ifunc definitions for __memchr_neon and __memchr_noneon. * sysdeps/arm/armv7/multiarch/memchr.S: New file. * sysdeps/arm/armv7/multiarch/memchr_impl.S: Likewise. * sysdeps/arm/armv7/multiarch/memchr_neon.S: Likewise. Testing done: Ran regression tests for arm-none-linux-gnueabihf as well as a full toolchain bootstrap. Benchmark tests were ran on ARMv7-A and ARMv8-A hardware targets.
