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/ctime

21f73d58 - [libc++] Remove workaround for C11 features on compilers that don't support using_if_exists

Wed, 18 Aug 2021 13:08:17 +0000

[libc++] Remove workaround for C11 features on compilers that don't support using_if_existsInstead of carrying around #ifdefs to determine whether those functionsare available on the platform, unconditionally use the using_if_existsattribute to import it into namespace std only when available. That wasthe purpose of this attribute from the start.This change means that trying to use libc++ with an old SDK (or on anold platform for platforms that ship system headers in /usr/include)will require a recent Clang that supports the using_if_exists attribute.When using an older Clang or GCC, the underlying platform has to supporta C11 standard library.Differential Revision: https://reviews.llvm.org/D108203 List of files: /llvm-project-15.0.7/libcxx/include/ctime

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/ctime

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/ctime

5201b962 - [libc++] Re-apply the workaround for timespec_get not always being available in Apple SDKs

Wed, 02 Sep 2020 14:36:48 +0000

[libc++] Re-apply the workaround for timespec_get not always being available in Apple SDKsThis commit re-applies 99f3b231cb21, which was reverted in 814242572731because it broke the modules build. The modules failure was a circulardependency between the Darwin module and __config. Specifically, theissue was that if <__config> includes a system header, the std_configmodule depends on the Darwin module. However, the Darwin module alreadydepends on the std_config header because some of its headers includelibc++ headers like (they mean to include the C ,but libc++ headers are first in the header search path).This is fixed by moving the workaround to only.https://llvm.org/PR47208rdar://68157284 List of files: /llvm-project-15.0.7/libcxx/include/ctime

19fd9039 - Fix _LIBCPP_HAS_ definitions for Android.

Mon, 18 Nov 2019 20:16:45 +0000

Fix _LIBCPP_HAS_ definitions for Android.Summary:Android added quick_exit()/at_quick_exit() in API level 21,aligned_alloc() in API level 28, and timespec_get() in API level 29,but has the other C11 features at all API levels (since they're basicallyjust coming from clang directly)._LIBCPP_HAS_QUICK_EXIT and _LIBCPP_HAS_TIMESPEC_GET already existed,so we can reuse them. (And use _LIBCPP_HAS_TIMESPEC_GET in a few moreplaces where _LIBCPP_HAS_C11_FEATURES has been used as a proxy. Thisisn't correct for Android.)_LIBCPP_HAS_ALIGNED_ALLOC is added, to cover aligned_alloc() (obviously).Add a missing std:: before aligned_alloc in a cstdlib test, and remove acouple of !defined(_WIN32)s now that we're explicitly testingTEST_HAS_ALIGNED_ALLOC rather than TEST_HAS_C11_FEATURES.Reviewers: danalbert, EricWF, mclow.listsReviewed By: danalbertSubscribers: srhines, christof, libcxx-commitsTags: #libcDifferential Revision: https://reviews.llvm.org/D69929 List of files: /llvm-project-15.0.7/libcxx/include/ctime

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/ctime

e0cf3b9a - Make support for thread-unsafe C functions optional.

Wed, 24 Jun 2015 08:44:38 +0000

Make support for thread-unsafe C functions optional.One of the aspects of CloudABI is that it aims to help you write codethat is thread-safe out of the box. This is very important if you wantto write libraries that are easy to reuse. For CloudABI we decided tonot provide the thread-unsafe functions. So far this is working outpretty well, as thread-unsafety issues are detected really early on.The following patch adds a knob to libc++,_LIBCPP_HAS_NO_THREAD_UNSAFE_C_FUNCTIONS, that can be set to disablethread-unsafe functions that can easily be avoided in practice. Thefollowing functions are not thread-safe:- : locale handles should be preferred over setlocale().- : mbrlen(), mbrtowc() and wcrtomb() should be preferred over their non-restartable counterparts.- : asctime(), ctime(), gmtime() and localtime() are not thread-safe. The first two are also deprecated by POSIX.Differential Revision: http://reviews.llvm.org/D8703Reviewed by: marshallllvm-svn: 240527 List of files: /llvm-project-15.0.7/libcxx/include/ctime
