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/cwchar

c137a075 - [libc++] Remove _LIBCPP_HAS_NO_LONG_LONG in favour of using_if_exists

Tue, 24 Aug 2021 14:30:39 +0000

[libc++] Remove _LIBCPP_HAS_NO_LONG_LONG in favour of using_if_exists_LIBCPP_HAS_NO_LONG_LONG was only defined on FreeBSD. Instead, use theusing_if_exists attribute to skip over declarations that are not availableon the base system. Note that there's an annoying limitation that we can'tconditionally define a function based on whether the base system providesa function, so for example we still need preprocessor logic to define theabs() and div() overloads.Differential Revision: https://reviews.llvm.org/D108630 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

87dd5198 - [libc++] Remove support for CloudABI, which has been abandoned

Tue, 24 Aug 2021 15:40:05 +0000

[libc++] Remove support for CloudABI, which has been abandonedBased on https://github.com/NuxiNL/cloudlibc, it appears that the CloudABIproject has been abandoned. This patch removes a bunch of CloudABI specificlogic that had been added to support that platform.Note that some knobs like LIBCXX_ENABLE_STDIN and LIBCXX_ENABLE_STDOUTcoud be useful in their own right, however those are currently broken.If we want to re-add such knobs in the future, we can do it like we'vedone it for localization & friends so that we can officially supportthat configuration.Differential Revision: https://reviews.llvm.org/D108637 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

a9c9183c - [libc++] Use the using_if_exists attribute when provided

Wed, 02 Jun 2021 14:41:37 +0000

[libc++] Use the using_if_exists attribute when providedAs discussed on cfe-dev [1], use the using_if_exists Clang attribute whenthe compiler supports it. This makes it easier to port libc++ on top ofnew platforms that don't fully support the C Standard library.Previously, libc++ would fail to build when trying to import a missingdeclaration in a header. With the attribute, the declaration willsimply not be imported into namespace std, and hence it won't be availablefor libc++ to use. In many cases, the declarations were *not* actuallyrequired for libc++ to work (they were only surfaced for users to usethem as std::XXXX), so not importing them into namespace std is acceptable.The same thing could be achieved by conscious usage of `#ifdef` alongwith platform detection, however that quickly creates a maintenanceproblem as libc++ is ported to new platforms. Furthermore, this problemis exacerbated when mixed with vendor internal-only platforms, which canlead to difficulties maintaining a downstream fork of the library.For the time being, we only use the using_if_exists attribute when itis supported. At some point in the future, we will start removing #ifdefpaths that are unnecessary when the attribute is supported, and folkswho need those #ifdef paths will be required to use a compiler thatsupports the attribute.[1]: http://lists.llvm.org/pipermail/cfe-dev/2020-June/066038.htmlDifferential Revision: https://reviews.llvm.org/D90257 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

57b08b09 - Update more file headers across all of the LLVM projects in the monorepo

Sat, 19 Jan 2019 10:56:40 +0000

Update more file headers across all of the LLVM projects in the monorepoto reflect the new license. These used slightly different spellings thatdefeated my regular expressions.We understand that people may be surprised that we're moving the headerentirely to discuss the new license. We checked this carefully with theFoundation's lawyer and we believe this is the correct approach.Essentially, all code in the project is now made available by the LLVMproject under our new license, so you will see that the license headersinclude that license only. Some of our contributors have contributedcode under our old license, and accordingly, we have retained a copy ofour old license notice in the top-level files in each project andrepository.llvm-svn: 351648 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

5fd17ab1 - Fix overload sets of strchr, strpbrk, strrchr, memchr and strstr from

Wed, 10 Feb 2016 00:59:02 +0000

Fix overload sets of strchr, strpbrk, strrchr, memchr and strstr from and wcschr, wcspbrk, wcsrchr, wmemchr, and wcsstr from toprovide a const-correct overload set even when the underlying C library doesnot.This change adds a new macro, _LIBCPP_PREFERRED_OVERLOAD, which (if defined)specifies that a given overload is a better match than an otherwise equallygood function declaration without the overload. This is implemented in modernversions of Clang via __attribute__((enable_if)), and not elsewhere.We use this new macro to define overloads in the global namespace for thesefunctions that displace the overloads provided by the C library, unless webelieve the C library is already providing the correct signatures.llvm-svn: 260337 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

f4ac884f - Make the presence of stdin and stdout optional.

Thu, 26 Mar 2015 14:35:46 +0000

Make the presence of stdin and stdout optional.The idea behind Nuxi CloudABI is that it is targeted at (but not limited to)running networked services in a sandboxed environment. The model behind stdin,stdout and stderr is strongly focused on interactive tools in a command shell.CloudABI does not support the notion of stdin and stdout, as 'standardinput/output' does not apply to services. The concept of stderr does makessense though, as services do need some mechanism to log error messages in auniform way.This patch extends libc++ in such a way that std::cin and std::cout and theassociated / functions can be disabled through the flags_LIBCPP_HAS_NO_STDIN and _LIBCPP_HAS_NO_STDOUT, respectively. At the same timeit attempts to clean up src/iostream.cpp a bit. Instead of using a single arrayof mbstate_t objects and hardcoding the array indices, it creates separateobjects that declared next to the iostream objects and their buffers. The codeis also restructured by interleaving the construction and setup of c* and wc*objects. That way it is more obvious that this is done identically.The c* and wc* objects already have separate unit tests. Make use of this factby adding XFAILs in case libcpp-has-no-std* is set. That way the tests work inboth directions. If stdin or stdout is disabled, these tests will thereforetest for the absence of c* and wc*.Differential Revision: http://reviews.llvm.org/D8340llvm-svn: 233275 List of files: /llvm-project-15.0.7/libcxx/include/cwchar

Thu, 01 Aug 2013 18:17:34 +0000

Nico Rieck: Currently _MSC_VER and _WIN32 are used to guard code which isMSVC-specific, MSVCRT-specific, or Windows-specific. Because Clang canalso define _MSC_VER, and MSVCRT is not necessarily the only C runtime,these macros should not be used interchangeably.This patch divides all Windows-related bits into the aforementionedcategories. Two new macros are introduced:- _LIBCPP_MSVC: Defined when compiling with MSVC. Detected using _MSC_VER, excluding Clang.- _LIBCPP_MSVCRT: Defined when using the Microsoft CRT. This is the default when _WIN32 is defined.This leaves _WIN32 for code using the Windows API.This also corrects the spelling of _LIBCP_HAS_IS_BASE_OF to _LIBCPP_HAS_IS_BASE_OF.Nico, please prepare a patch for CREDITS.TXT, thanks.llvm-svn: 187593 List of files: /llvm-project-15.0.7/libcxx/include/cwchar
