2021-04-13libstdc++: Remove outdated docs on libg++ and libstdc++-v2Jonathan Wakely6-934/+25
The libstdc++-v3 manual doesn't need to document how to use its predecessors. libstdc++-v3/ChangeLog: * doc/xml/manual/backwards_compatibility.xml: Remove porting notes for libg++ and libstdc++-v2, and bibliography. * doc/html/*: Regenerated.
2021-04-08libstdc++: Improve error reporting if PDF generation failsJonathan Wakely2-0/+2
If pdflatex runs out of memory the build fails with no hint what's wrong. This adds another grep command to the makefile so that an out-of-memory error will result in more information being shown. As suggested in https://bugzilla.redhat.com/show_bug.cgi?id=1841056 using lualatex can be used as a workaround. libstdc++-v3/ChangeLog: * doc/Makefile.am (stamp-pdf-doxygen): Also grep for out-of-memory error in log file. * doc/Makefile.in: Regenerate.

2021-02-12libstdc++: Fix filesystem::rename on Windows [PR 98985]Jonathan Wakely6-9/+73
The _wrename function won't overwrite an existing file, so use MoveFileEx instead. That allows renaming directories over files, which POSIX doesn't allow, so check for that case explicitly and report an error. Also document the deviation from the expected behaviour, and add a test for filesystem::rename which was previously missing. The Filesystem TS experimental::filesystem::rename doesn't have that extra code to handle directories correctly, so the relevant parts of the new test are not run on Windows. libstdc++-v3/ChangeLog: * doc/xml/manual/status_cxx2014.xml: Document implementation specific properties of std::experimental::filesystem::rename. * doc/xml/manual/status_cxx2017.xml: Document implementation specific properties of std::filesystem::rename. * doc/html/*: Regenerate. * src/c++17/fs_ops.cc (fs::rename): Implement correct behaviour for directories on Windows. * src/filesystem/ops-common.h (__gnu_posix::rename): Use MoveFileExW on Windows. * testsuite/27_io/filesystem/operations/rename.cc: New test. * testsuite/experimental/filesystem/operations/rename.cc: New test.

2021-01-27libstdc++: Add std::experimental::simd from the Parallelism TS 2Matthias Kretz1-0/+216
Adds <experimental/simd>. This implements the simd and simd_mask class templates via [[gnu::vector_size(N)]] data members. It implements overloads for all of <cmath> for simd. Explicit vectorization of the <cmath> functions is not finished. The majority of functions are marked as [[gnu::always_inline]] to enable quasi-ODR-conforming linking of TUs with different -m flags. Performance optimization was done for x86_64. ARM, Aarch64, and POWER rely on the compiler to recognize reduction, conversion, and shuffle patterns. Besides verification using many different machine flages, the code was also verified with different fast-math flags. libstdc++-v3/ChangeLog: * doc/xml/manual/status_cxx2017.xml: Add implementation status of the Parallelism TS 2. Document implementation-defined types and behavior. * include/Makefile.am: Add new headers. * include/Makefile.in: Regenerate. * include/experimental/simd: New file.

2020-12-16libstdc++: Add C++ runtime support for new 128-bit long double formatJonathan Wakely1-1/+5
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.

2020-11-26ada: c++: Get rid of libposix4, librt on SolarisRainer Orth1-2/+1
I recently noticed that neither libposix4 nor librt are needed on Solaris 11 any longer: * libposix4 was renamed to librt in Solaris 7 back in 1998. * librt was folded into libc in the OpenSolaris timeframe, leaving librt only as a filter on libc. Thus, it's no longer needed on either Solaris 11 or Illumos. The following patch removes both uses. At the same time, Ada's use of libthread has gone: it was folded into libc in Solaris 10 already. TIME_LIBRARY and friends in g++ are likewise removed: Solaris was the only user. Bootstrapped without regressions on i386-pc-solaris2.11, sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2020-11-16 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gcc/cp: * g++spec.c (TIMELIB, TIME_LIBRARY): Remove.

2020-06-01libstdc++: Fix incorrect Docbook linksJonathan Wakely4-6/+8
The <xref> element creates the link text automatically from the link target, rather than using the text node child of the element. This can be changed by using an endterm attribute, but it's simpler to just use the <link> element instead. * doc/xml/manual/containers.xml: Replace <xref> with <link>. * doc/xml/manual/evolution.xml: Likewise. * doc/html/manual/api.html: Regenerate. * doc/html/manual/containers.html: Regenerate.

2020-04-23libstdc++: Update C++20 library status docsJonathan Wakely5-1028/+1138
This reorganises the C++20 status table, grouping the proposals by category. It also adds more proposals, and documents all the feature test macros for C++20 library changes. * doc/xml/manual/status_cxx2020.xml: Update C++20 status table. * doc/html/*: Regenerate.
2020-04-21libstdc++: Improve C++14 and C++17 status docsJonathan Wakely8-235/+3467
This adds a full table of contents for the C++14 and C++17 standards, with status for each part. For C++14 the list of proposals is removed, as it adds little value now that everything is supported. For C++17 the table of proposals is retained, because it documents he feature test macros for the features. * doc/Makefile.am (xml_sources_manual): Add missing XML files. * doc/Makefile.in: Regenerate. * doc/xml/manual/status_cxx1998.xml: Refer to "this section" instead of "this page". * doc/xml/manual/status_cxx2011.xml: Formatting and other corrections to the C++11 status table. * doc/xml/manual/status_cxx2014.xml: Replace list of C++14 feature proposals with table matching contents of the C++14 standard. * doc/xml/manual/status_cxx2017.xml: Add table matching contents of the C++17 standard. * doc/html/*: Regenerate.

2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki1-0/+1
Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in. In the presence of the `--enable-version-specific-runtime-libs' option and for configurations building native GCC the option is ignored. config/ * toolexeclibdir.m4: New file. gcc/ * doc/install.texi (Cross-Compiler-Specific Options): Document `--with-toolexeclibdir' option. libada/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libatomic/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libffi/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * include/Makefile.in: Regenerate. * man/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libgcc/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libgfortran/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libgomp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libhsail-rt/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libitm/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libobjc/ * Makefile.in (aclocal_deps): Add `toolexeclibdir.m4'. * aclocal.m4: Include `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. liboffloadmic/ * plugin/configure.ac: Handle `--with-toolexeclibdir='. * plugin/Makefile.in: Regenerate. * plugin/aclocal.m4: Regenerate. * plugin/configure: Regenerate. * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libphobos/ * m4/druntime.m4: Handle `--with-toolexeclibdir='. * m4/Makefile.in: Regenerate. * libdruntime/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libquadmath/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libsanitizer/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * asan/Makefile.in: Regenerate. * interception/Makefile.in: Regenerate. * libbacktrace/Makefile.in: Regenerate. * lsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.in: Regenerate. * tsan/Makefile.in: Regenerate. * ubsan/Makefile.in: Regenerate. libssp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libstdc++-v3/ * acinclude.m4: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * include/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libvtv/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. zlib/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate.
