2fb8f67e - [libc++] Allow enabling assertions when back-deploying

Thu, 04 Aug 2022 19:25:48 +0000

[libc++] Allow enabling assertions when back-deployingWhen back-deploying to older platforms, we can still provide assertions,but we might not be able to provide a great implementation for the verbosehandler. Instead, we can just call ::abort().Differential Revision: https://reviews.llvm.org/D131199(cherry picked from commit e36f9e13bca41223bd6af7e49bf020e58a676e9d) List of files: /llvm-project-15.0.7/libcxx/utils/ci/run-buildbot

f1c30135 - [libc++] Drop the legacy debug mode symbols by default

Tue, 19 Jul 2022 15:04:31 +0000

[libc++] Drop the legacy debug mode symbols by defaultLeave the escape hatch in place with a note, but don't include thedebug mode symbols by default since we don't support the debug modein the normal library anymore.This is technically an ABI break for users who were depending onthose debug mode symbols in the dylib, however those users willalready be broken at compile-time because they must have been using_LIBCPP_DEBUG=2, which is now an error.Differential Revision: https://reviews.llvm.org/D127360 List of files: /llvm-project-15.0.7/libcxx/utils/ci/run-buildbot

8711fcae - [libc++] Treat incomplete features just like other experimental features

Thu, 30 Jun 2022 15:57:52 +0000

[libc++] Treat incomplete features just like other experimental featuresIn particular remove the ability to expel incomplete features from thelibrary at configure-time, since this can now be done through the_LIBCPP_ENABLE_EXPERIMENTAL macro.Also, never provide symbols related to incomplete features inside thedylib, instead provide them in c++experimental.a (this changes thesymbols list, but not for any configuration that should have shipped).Differential Revision: https://reviews.llvm.org/D128928 List of files: /llvm-project-15.0.7/libcxx/utils/ci/run-buildbot

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/utils/ci/run-buildbot

1cf41139 - [libcxx][AIX] Switch build compiler to clang

Tue, 14 Jun 2022 01:44:58 +0000

[libcxx][AIX] Switch build compiler to clangThis patch switches the build compiler for AIX from ibm-clang to clang. ibm-clang++_r has `-pthread` by default, but clang for AIX doesn't, so `-pthread` had to be added to the test config. A bunch of tests now pass, so the `XFAIL` was removed. This patch also switch the build to use the visibility support available in clang-15 to control symbols exported by the shared library (AIX traditionally uses explicit export lists for this purpose).Reviewed By: #libc, #libc_abi, daltenty, #libunwind, ldionneDifferential Revision: https://reviews.llvm.org/D127470 List of files: /llvm-project-15.0.7/libcxx/utils/ci/run-buildbot

f3966eaf - [libc++] Make the Debug mode a configuration-time only option

Fri, 01 Apr 2022 20:38:30 +0000

[libc++] Make the Debug mode a configuration-time only optionThe debug mode has been broken pretty much ever since it was shippedbecause it was possible to enable the debug mode in user code withoutactually enabling it in the dylib, leading to ODR violations thatcaused various kinds of failures.This commit makes the debug mode a knob that is configured whenbuilding the library and which can't be changed afterwards. This isless flexible for users, however it will actually work as intendedand it will allow us, in the future, to add various kinds of checksthat do not assume the same ABI as the normal library. Furthermore,this will make the debug mode more robust, which means that vendorsmight be more tempted to support it properly, which hasn't been thecase with the current debug mode.This patch shouldn't break any user code, except folks who are buildingagainst a library that doesn't have the debug mode enabled and who tryto enable the debug mode in their code. Such users will get a compile-timeerror explaining that this configuration isn't supported anymore.In the future, we should further increase the granularity of the debugmode checks so that we can cherry-pick which checks to enable, like wedo for unspecified behavior randomization.Differential Revision: https://reviews.llvm.org/D122941 List of files: /llvm-project-15.0.7/libcxx/utils/ci/run-buildbot
