368faaca - [libc++] Revert "Protect users from relying on detail headers" & related changes

Mon, 28 Feb 2022 21:37:25 +0000

[libc++] Revert "Protect users from relying on detail headers" & related changesThis commit reverts 5aaefa51 (and also partly 7f285f48e77 and b6d75682f9,which were related to the original commit). As landed, 5aaefa51 hadunintended consequences on some downstream bots and didn't have propercoverage upstream due to a few subtle things. Implementing this issomething we should do in libc++, however we'll first need to addressa few issues listed in https://reviews.llvm.org/D106124#3349710.Differential Revision: https://reviews.llvm.org/D120683 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

5aaefa51 - [libcxx][modules] protects users from relying on detail headers

Fri, 25 Feb 2022 18:59:32 +0000

[libcxx][modules] protects users from relying on detail headerslibc++ has started splicing standard library headers into much morefine-grained content for maintainability. It's very likely that outdatedand naive tooling (some of which is outside of LLVM's scope) willsuggest users include things such as <__ranges/access.h> instead of, and Hyrum's law suggests that users will eventually begin torely on this without the help of tooling. As such, this commitintends to protect users from themselves, by making it a hard error foranyone outside of the standard library to include libc++ detail headers.Differential Revision: https://reviews.llvm.org/D106124 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

eb8650a7 - [runtimes][NFC] Remove filenames at the top of the license notice

[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.

a9b5fff5 - [libcxx{,abi}] Emit deplibs only when detected by CMake

Mon, 02 Dec 2019 10:49:20 +0000

[libcxx{,abi}] Emit deplibs only when detected by CMakeThis is a followup to 35bc5276ca3. It fixes the dependent libs usagein libcxx and libcxxabi to link pthread and rt libraries only if CMakedetects them, rather than based on explicit platform blacklist.Differential Revision: https://reviews.llvm.org/D70888 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

04501a22 - [libc++abi] Remove uses of C++ headers when possible

Tue, 01 Oct 2019 18:43:02 +0000

[libc++abi] Remove uses of C++ headers when possibleThis reduces the (circular) dependency of libc++abi on a C++ standardlibrary. Outside of the demangler which uses fancier C++ features, theonly C++ headers now required by libc++abi are pretty much and, and that's because libc++abi defines some types that aredeclared in those headers.llvm-svn: 373381 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

[runtimes] Check if pragma comment(lib, ...) is supported firstThis fixes the issue introduced by r362048 where we always usepragma comment(lib, ...) for dependent libraries when the compileris Clang, but older Clang versions don't support this pragma sowe need to check first if it's supported before using it.llvm-svn: 362055 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

996e62ee - [runtimes] Support ELF dependent libraries feature

Thu, 30 May 2019 01:34:41 +0000

[runtimes] Support ELF dependent libraries featureAs of r360984, LLD supports dependent libraries feature for ELF.libunwind, libc++abi and libc++ have library dependencies: libdl librtand libpthread, which means that when libunwind and libc++ are beingstatically linked (using -static-libstdc++ flag), user has to manuallyspecify -ldl -lpthread which is onerous.This change includes the lib pragma to specify the library dependenciesdirectly in the source that uses those libraries. This doesn't make anydifference when using linkers that don't support dependent libraries.However, when using LLD that has dependent libraries feature, users nolonger have to manually specifying library dependencies when usingstatic linking, linker will pick the library automatically.Differential Revision: https://reviews.llvm.org/D62090llvm-svn: 362048 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp

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/libcxxabi/src/cxa_thread_atexit.cpp

fe989a98 - [libc++abi] Clean up visibility

Wed, 01 Mar 2017 03:55:57 +0000

[libc++abi] Clean up visibilityUse the libc++abi visibility macros instead of pragmas or usingvisibility attributes directly. Clean up redundant attributes ondefinitions (where the declarations already have visibility attributesapplied, from either libc++ or libc++abi headers).Introduce _LIBCXXABI_WEAK as a drive-by cleanup, which matches thesemantics of _LIBCPP_WEAK.No functional change. Tested by building on Linux before and after thischange and verifying that the list of exported symbols is identical.Differential Revision: https://reviews.llvm.org/D26949llvm-svn: 296576 List of files: /llvm-project-15.0.7/libcxxabi/src/cxa_thread_atexit.cpp
