Jonathan Wakely	ad0a3be4df	libstdc++: Remove _GLIBCXX_USE_INT128 autoconf macro ... We don't need to decide whether to use __int128 when running configure, we can do so at compilation time by seeing if __SIZEOF_INT128__ is defined and if it's greater than __SIZEOF_LONG_LONG__. This removes another unnecessary architecture-specific config macro in <bits/c++config.h>, so the same header can work for 32-bit or 64-bit compilation on AIX. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_ENABLE_INT128_FLOAT128): Remove checks for __int128 and rename to GLIBCXX_ENABLE_FLOAT128. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac: Adjust to use GLIBCXX_ENABLE_FLOAT128. * include/bits/random.h (_Select_uint_least_t<s, 1>): Use __SIZEOF_INT128__ to decide whether to use __int128. * include/std/charconv (__to_chars_unsigned_type): Likewise.	2021-05-04 12:07:09 +01:00
Jonathan Wakely	7ddcd26ebb	libstdc++: Remove GLIBCXX_CHECK_INT64_T checks ... This simplifies the definition of std::streamoff by using the predefined __INT64_TYPE__ macro, instead of the _GLIBCXX_HAVE_INT64_T_LONG, _GLIBCXX_HAVE_INT64_T_LONG_LONG and _GLIBCXX_HAVE_INT64_T macros defined by configure. By using the __INT64_TYPE__ macro (which all of GCC, Clang and Intel define) we do not need to determine the type of int64_t in configure, we can just use that type directly. The background for the change was explained by David Edelsohn: Currently the type of streamoff is determined at libstdc++ configure time, chosen by the definitions of _GLIBCXX_HAVE_INT64_T_LONG and _GLIBCXX_HAVE_INT64_T_LONG_LONG. For a multilib configuration, the difference is encoded in the different multilib header file paths. For "FAT" library targets that package 32 bit and 64 bit libraries together, G++ also expects a single header file directory hierarchy, causing an incorrect value for streamoff in some situations. And in a subsequent mail: Most of the libstdc++ headers are architecture-neutral, OS neutral and ABI neutral. The differences are localized in bits/c++config.h. And most of c++config.h is identical for 32 bit AIX and 64 bit AIX. The only differences that matter are __int128 and __int64_t. This change removes some of those differences. With the only uses of the INT64_T configure macros removed, the configure checks themselves can also be removed.

(streamoff): Use __INT64_TYPE__ if defined.	2021-04-30 20:30:46 +01:00
Jonathan Wakely	7c1e7eed89	libstdc++: Add C++ runtime support for new 128-bit long double format ... This adds support for the new __ieee128 long double format on powerpc64le targets. Most of the complexity comes from wanting a single libstdc++.so library that contains the symbols needed by code compiled with both -mabi=ibmlongdouble and -mabi=ieeelongdouble (and not forgetting -mlong-double-64 as well!) In a few places this just requires an extra overload, for example std::from_chars has to be overloaded for both forms of long double. That can be done in a single translation unit that defines overloads for 'long double' and also '__ieee128', so that user code including <charconv> will be able to link to a definition for either type of long double. Those are the easy cases. The difficult parts are (as for the std::string ABI transition) the I/O and locale facets. In order to be able to write either form of long double to an ostream such as std::cout we need the locale to contain a std::num_put facet that can handle both forms. The same approach is taken as was already done for supporting 64-bit long double and 128-bit long double: adding extra overloads of do_put to the facet class. On targets where the new long double code is enabled, the facets that are registered in the locale at program startup have additional overloads so that they can work with any long double type. Where this fails to work is if user code installs its own facet, which will probably not have the additional overloads and so will only be able to output one or the other type. In practice the number of users expecting to be able to use their own locale facets in code using a mix of -mabi=ibmlongdouble and -mabi=ieeelongdouble is probably close to zero. libstdc++-v3/ChangeLog: * Makefile.in: Regenerate. * config.h.in: Regenerate. * config/abi/pre/gnu.ver: Make patterns less greedy. * config/os/gnu-linux/ldbl-ieee128-extra.ver: New file with patterns for IEEE128 long double symbols. * configure: Regenerate. * configure.ac: Enable alternative 128-bit long double format on powerpc64*-*-linux*. * doc/Makefile.in: Regenerate. * fragment.am: Regenerate. * include/Makefile.am: Set _GLIBCXX_LONG_DOUBLE_ALT128_COMPAT. * include/Makefile.in: Regenerate. * include/bits/c++config: Define inline namespace for new long double symbols.

Jonathan Wakely	a2c2eec183	libstdc++: Test errno macros directly, not via autoconf [PR 93151] ... This fixes a bug caused by a mismatch between the macros defined by <errno.h> when GCC is built and the macros defined by <errno.h> when users include <system_error>. If the user code is compiled with _XOPEN_SOURCE defined to 500 or 600, Darwin suppresses the ENOTRECOVERABLE and EOWNERDEAD macros, which are not defined by SUSv3 (aka POSIX.1-2001). Since POSIX requires the errno macros to be macros (and not variables or enumerators) we can just test for them directly using the preprocessor. That means that <system_error> will match what is actuallydefined when it's included, not what was defined when GCC was built. With that change there is no need for the GLIBCXX_CHECK_SYSTEM_ERROR configure checks and they can be removed. libstdc++-v3/ChangeLog: PR libstdc++/93151 * acinclude.m4 (GLIBCXX_CHECK_SYSTEM_ERROR): Remove. * configure.ac: Regenerate. * config/os/generic/error_constants.h: Test POSIX errno macros directly, instead of corresponding _GLIBCXX_HAVE_EXXX macros. * testsuite/19_diagnostics/headers/system_error/errc_std_c++0x.cc: Likewise. * testsuite/19_diagnostics/headers/system_error/93151.cc: New test.	2020-12-16 13:36:02 +00:00

Jonathan Wakely	932fbc868a	libstdc++: Add std::from_chars for floating-point types ... This adds the missing std::from_chars overloads for floating-point types, as required for C++17 conformance. The implementation is a hack and not intended to be used in the long term. Rather than parsing the string directly, this determines the initial portion of the string that matches the pattern determined by the chars_format parameter, then creates a NTBS to be parsed by strtod (or strtold or strtof). Because creating a NTBS requires allocating memory, but std::from_chars is noexcept, we need to be careful to minimise allocation. Even after being careful, allocation failure is still possible, and so a non-conforming std::no_more_memory error code might be returned. Because strtod et al depend on the current locale, but std::from_chars does not, we change the current thread's locale to "C" using newlocale and uselocale before calling strtod, and restore it afterwards. Because strtod doesn't have the equivalent of a std::chars_format parameter, it has to examine the input to determine the format in use, even though the std::from_chars code has already parsed it once (or twice for large input strings!) By replacing the use of strtod we could avoid allocation, avoid changing locale, and use optimised code paths specific to each std::chars_format case. We would also get more portable behaviour, rather than depending on the presence of uselocale, and on any bugs or quirks of the target libc's strtod. Replacing strtod is a project for a later date. libstdc++-v3/ChangeLog: * acinclude.m4 (libtool_VERSION): Bump version. * config.h.in: Regenerate. * config/abi/pre/gnu.ver: Add GLIBCXX_3.4.29 version and new exports. * config/os/gnu-linux/ldbl-extra.ver: Add _GLIBCXX_LDBL_3.4.29 version and new export. * configure: Regenerate. * configure.ac: Check for <xlocale.h> and uselocale. * crossconfig.m4: Add macro or checks for uselocale. * include/std/charconv (from_chars): Declare overloads for float, double, and long double. * src/c++17/Makefile.am: Add new file. * src/c++17/Makefile.in: Regenerate. * src/c++17/floating_from_chars.cc: New file.

David Edelsohn	47ddb895df	aix: Add GCC64 configuration and FAT target libraries. ... This patch adds the ability to configure GCC on AIX to build as a 64 bit application and to build target libraries "FAT" libraries in both 32 bit and 64 bit mode. The patch adds makefile fragment hooks to target libraries that allows them to include target-specific rules. The target specific rules for AIX place both 32 bit and 64 bit objects and shared objects in archives at the top-level, not multilib subdirectories. The multilibs are built in subdirectories, but must be combined during the last parts of the target library build process. Because of the way that GCC bootstrap works, the libraries must be combined during the multiple stages of GCC bootstrap, not solely when installed in the final destination, so the libraries are correct at the end of each target library build stage, not solely an install recipe. gcc/ChangeLog 2020-06-21 David Edelsohn <dje.gcc@gmail.com> * config.gcc: Use t-aix64, biarch64 and default64 for cpu_is_64bit. * config/rs6000/aix72.h (ASM_SPEC): Remove aix64 option.

Mike Crowe	ab40695a46	libstdc++: Add full steady_clock support to shared_timed_mutex ... The pthread_rwlock_clockrdlock and pthread_rwlock_clockwrlock functions were added to glibc in v2.30. They have also been added to Android Bionic. If these functions are available in the C library then they can be used to implement shared_timed_mutex::try_lock_until, shared_timed_mutex::try_lock_for, shared_timed_mutex::try_lock_shared_until and shared_timed_mutex::try_lock_shared_for so that they are no longer unaffected by the system clock being warped. (This is the shared_mutex equivalent of PR libstdc++/78237 for mutex.) If the new functions are available then steady_clock is deemed to be the "best" clock available which means that it is used for the relative try_lock_for calls and absolute try_lock_until calls using steady_clock and user-defined clocks. It's not possible to have _GLIBCXX_USE_PTHREAD_RWLOCK_CLOCKLOCK defined without _GLIBCXX_USE_PTHREAD_RWLOCK_T, so the requirement that the clock be the same as condition_variable is maintained. Calls explicitly using system_clock (aka high_resolution_clock) continue to use CLOCK_REALTIME via the old pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock functions. If the new functions are not available then system_clock is deemed to be the "best" clock available which means that the previous suboptimal behaviour remains. Additionally, the user-defined clock used with shared_timed_mutex::try_lock_for and shared_mutex::try_lock_shared_for may have higher precision than __clock_t. We may need to round the duration up to ensure that the timeout is long enough.

Jonathan Wakely	b0c0d878a8	PR libstdc++/85494 use rdseed and rand_s in std::random_device ... Add support for additional sources of randomness to std::random_device, to allow using RDSEED for Intel CPUs and rand_s for Windows. When supported these can be selected using the tokens "rdseed" and "rand_s". For *-w64-mingw32 targets the "default" token will now use rand_s, and for other i?86-*-* and x86_64-*-* targets it will try to use "rdseed" first, then "rdrand", and finally "/dev/urandom". To simplify the declaration of std::random_device in <bits/random.h> the constructors now unconditionally call _M_init instead of _M_init_pretr1, and the function call operator now unconditionally calls _M_getval. The library code now decides whether _M_init and _M_getval should use a real source of randomness or the mt19937 engine. Existing code compiled against old libstdc++ headers will still call _M_init_pretr1 and _M_getval_pretr1, but those functions now forward to _M_init and _M_getval if a real source of randomness is available.

Jonathan Wakely	a4395a846a	PR libstdc++/89466 avoid slow xsltproc command in configure ... Certain broken versions of xsltproc ignore the --nonet option and will attempt to fetch the docbook stylesheet from the WWW when it isn't in the local XML catalog. This patch checks for the local stylesheet directory first, and doesn't use xsltproc if no local stylesheets are found. Checking for the local directory is done using xmlcatalog if available, only checking the hardcoded list of directories if xmlcatalog fails. The right directory for Suse is added to the hardcoded list. This should avoid doing an xsltproc check that would need to download the stylesheet, so no network connection is made even if a broken xsltproc is present.

Jonathan Wakely	da29d2a36e	PR libstdc++/67843 set shared_ptr lock policy at build-time ... This resolves a longstanding issue where the lock policy for shared_ptr reference counting depends on compilation options when the header is included, so that different -march options can cause ABI changes. For example, objects compiled with -march=armv7 will use atomics to synchronize reference counts, and objects compiled with -march=armv5t will use a mutex. That means the shared_ptr control block will have a different layout in different objects, causing ODR violations and undefined behaviour. This was the root cause of PR libstdc++/42734 as well as PR libstdc++/67843. The solution is to decide on the lock policy at build time, when libstdc++ is configured. The configure script checks for the availability of the necessary atomic built-ins for the target and fixes that choice permanently. Different -march flags used to compile user code will not cause changes to the lock policy. This results in an ABI change for certain compilations, but only where there was already an ABI incompatibility between the libstdc++.so library and objects built with an incompatible -march option. In general, this means a more stable ABI that isn't silently altered when -march flags make addition atomic ops available. To force a target to use "atomic" or "mutex" the new configure option --with-libstdcxx-lock-policy can be used. In order to turn ODR violations into linker errors, the uses of shared_ptr in filesystem directory iterators have been replaced with __shared_ptr, and explicit instantiations are declared. This ensures that object files using those types cannot link to libstdc++ libs unless they use the same lock policy.

Joseph Myers	22e0527251	Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856). ... This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.

Jonathan Wakely	c3be340eb6	PR libstdc++/86450 use -Wabi=2 and simplify -Werror use ... Use -Wabi=2 to fix warnings about -Wabi having no effect on its own. This requires suppressing two warnings in src/c++11/debug.cc which do not affect the library ABI. Previously libstdc++ defaulted to --enable-werror but the -Werror flag was not actually added unless --enable-maintainer-mode was used. This is not documented and not the expected behaviour. This removes any special treatment for maintainer-mode, makes -Werror depend directly on --enable-werror, and changes the default to --enable-werror=no.
