50cfb76e - [libc++] Define ostream nullptr inserter for >= C++17 only

Fri, 03 Jun 2022 23:05:23 +0000

[libc++] Define ostream nullptr inserter for >= C++17 onlyThe `ostream` `nullptr` inserter implemented in 3c125fe is missing a C++ versionguard. Normally, `libc++` takes the stance of backporting LWG issues to olderstandards modes as was done in 3c125fe. However, backporting to older standardsmodes breaks existing code in popular libraries such as `Boost.Test` and`Google Test` who define their own overload for `nullptr_t`.Instead, only apply this `operator<<` overload in C++17 or later.Fixes https://github.com/llvm/llvm-project/issues/55861.Differential Revision: https://reviews.llvm.org/D127033 List of files: /llvm-project-15.0.7/libcxx/include/ostream

de4a57cb - [libc++] Re-add transitive includes that had been removed since LLVM 14

Mon, 27 Jun 2022 19:53:41 +0000

[libc++] Re-add transitive includes that had been removed since LLVM 14This commit re-adds transitive includes that had been removed by4cd04d1687f1, c36870c8e79c, a83f4b9cda57, 1458458b558d, 2e2f3158c604,and 489637e66dd3. This should cover almost all the includes that hadbeen removed since LLVM 14 and that would contribute to breaking usercode when releasing LLVM 15.It is possible to disable the inclusion of these headers by defining_LIBCPP_REMOVE_TRANSITIVE_INCLUDES. The intent is that vendors willenable that macro and start fixing downstream issues immediately. Wecan then remove the macro (and the transitive includes) by default ina future release. That way, we will break users only once by removingtransitive includes in bulk instead of doing it bit by bit a everyrelease, which is more disruptive for users.Note 1: The set of headers to re-add was found by re-generating the transitive include test on a checkout of release/14.x, which provided the list of all transitive includes we used to provide.Note 2: Several includes of , , and have been added in this commit. These transitive inclusions were added when we implemented boyer_moore_searcher in .Note 3: This is a best effort patch to try and resolve downstream breakage caused since branching LLVM 14. I wasn't able to perfectly mirror transitive includes in LLVM 14 for a few headers, so I added a release note explaining it. To summarize, adding boyer_moore_searcher created a bunch of circular dependencies, so we have to break backwards compatibility in a few cases.Differential Revision: https://reviews.llvm.org/D128661 List of files: /llvm-project-15.0.7/libcxx/include/ostream

2ae52326 - [libc++] Towards a simpler extern template story in libc++

Tue, 08 Jun 2021 21:25:08 +0000

[libc++] Towards a simpler extern template story in libc++The flexibility around extern template instantiation declarations inlibc++ result in a very complicated model, especially when support forslightly different configurations (like the debug mode or assertionsin the dylib) are taken into account. That results in unexpected bugslike http://llvm.org/PR50534 (and there have been multiple similarbugs in the past, notably around the debug mode).This patch gets rid of the _LIBCPP_DISABLE_EXTERN_TEMPLATE knob, whichI don't think is fundamental. Indeed, the motivation for that knob was toavoid taking a dependency on the library, however that can be done betterby linking against the static library instead. And in fact, some parts ofthe headers will always depend on things defined in the library, whichdefeats the original goal of _LIBCPP_DISABLE_EXTERN_TEMPLATE.Differential Revision: https://reviews.llvm.org/D103960 List of files: /llvm-project-15.0.7/libcxx/include/ostream

385cc25a - [libc++] Ensure that all public C++ headers include <__assert>

Fri, 25 Mar 2022 16:55:36 +0000

[libc++] Ensure that all public C++ headers include <__assert>This patch changes the requirement for getting the declaration of theassertion handler from including <__assert> to including any publicC++ header of the library. Note that C compatibility headers areexcluded because we don't implement all the C headers ourselves --some of them are taken straight from the C library, like assert.h.It also adds a generated test to check it. Furthermore, this newgenerated test is designed in a way that will make it possible toreplace almost all the existing test-generation scripts with thissystem in upcoming patches.Differential Revision: https://reviews.llvm.org/D122506 List of files: /llvm-project-15.0.7/libcxx/include/ostream

Mon, 23 Aug 2021 19:32:36 +0000

[libc++] Add an option to disable wide character support in libc++Some embedded platforms do not wish to support the C library functionalityfor handling wchar_t because they have no use for it. It makes sense forlibc++ to work properly on those platforms, so this commit adds a carve-outof functionality for wchar_t.Unfortunately, unlike some other carve-outs (e.g. random device), thispatch touches several parts of the library. However, despite the wideimpact of this patch, I still think it is important to support thisconfiguration since it makes it much simpler to port libc++ to someembedded platforms.Differential Revision: https://reviews.llvm.org/D111265 List of files: /llvm-project-15.0.7/libcxx/include/ostream

[libc++] Remove some _LIBCPP_CXX03_LANG from iostreams headers.With the STL containers, I didn't enable move operations in C++03 modebecause that would change the overload resolution for things that todayare copy operations. With iostreams, though, the copy operations aren'tpresent at all, and so I see no problem with enabling move operationseven in (Clang's greatly extended) C++03 mode.Clang's C++03 mode does not support delegating constructors.Differential Revision: https://reviews.llvm.org/D104310 List of files: /llvm-project-15.0.7/libcxx/include/ostream
