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/istream

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/istream

e39095a3 - [libc++] Define _LIBCPP_HAS_NO_PRAGMA_SYSTEM_HEADER whenever we enable warnings in the test suite

Thu, 03 Mar 2022 18:39:12 +0000

[libc++] Define _LIBCPP_HAS_NO_PRAGMA_SYSTEM_HEADER whenever we enable warnings in the test suiteThis should make CI consistent on all the compilers we support. Most ofthis patch is working around various warnings emitted by GCC in our codebase, which are now being shown when we compile the tests.After this patch, the whole test suite should be warning free on allcompilers we support and test, except for a few warnings on GCC thatwe silence explicitly until we figure out the proper fix for them.Differential Revision: https://reviews.llvm.org/D120684 List of files: /llvm-project-15.0.7/libcxx/include/istream

[runtimes][NFC] Remove filenames at the top of the license noticeWe've stopped doing it in libc++ for a while now because these nameswould end up rotting as we move things around and copy/paste stuff.This cleans up all the existing files so as to stop the spreadingas people copy-paste headers around.

f4c1258d - [libc++] Add an option to disable wide character support in libc++

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/istream

a8d1182f - [libc++] Remove some _LIBCPP_CXX03_LANG from iostreams headers.

Tue, 15 Jun 2021 16:47:05 +0000

[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/istream

317e92a3 - [libc++] Enable `explicit` conversion operators, even in C++03 mode.

Tue, 15 Jun 2021 16:57:54 +0000

[libc++] Enable `explicit` conversion operators, even in C++03 mode.C++03 didn't support `explicit` conversion operators;but Clang's C++03 mode does, as an extension, so we can use it.This lets us make the conversion explicit in `std::function` (even in '03),and remove some silly metaprogramming in `std::basic_ios`.Drive-by improvements to the tests for these operators, in additionto making sure all these tests also run in `c++03` mode.Differential Revision: https://reviews.llvm.org/D104682 List of files: /llvm-project-15.0.7/libcxx/include/istream

[libc++] Implement LWG1203Libc++ had an issue where nonsensical code like decltype(std::stringstream{} << std::vector{});would compile, as long as you kept the expression inside decltype inan unevaluated operand.
