  "message": "Revert \"Roll libc++ from b16984ce99c7 to 97b436da4c33 (215 revisions)\"\n\nThis reverts commit f25e1b6e8f70fad3d0bed260a1a9838da2878a83\n\nReason for revert: Tree close due to the build failures\n\nFailure Link: https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20CFI/32553/overview\n\nOriginal change\u0027s description:\n\u003e Roll libc++ from b16984ce99c7 to 97b436da4c33 (215 revisions)\n\u003e\n\u003e https://chromium.googlesource.com/external/github.com/llvm/llvm-project/libcxx.git/+log/b16984ce99c7..97b436da4c33\n\u003e\n\u003e This change causes a large increase in binary size that is likely\n\u003e due to `_LIBCPP_ABI_VECTOR_LAYOUT_SIZE_BASED`. However, we cannot\n\u003e disable that feature as a separate PR introduced a change that\n\u003e requires complete types to call `empty()` on vectors, which breaks\n\u003e our builds. It is also possible that new PGO profiles will reduce\n\u003e the binary size, so we should land this to compare canary binary sizes\n\u003e in a couple days. If the profiles don\u0027t change anything we can revert\n\u003e this roll. See the linked bug crbug.com/534049474 for more discussion\n\u003e around the binary size increase.\n\u003e\n\u003e This change replaces a multi-cast in playback_rate_shifter.cc on\n\u003e buffer-\u003echannel_data().data() with an explicit\n\u003e std::array\u003cfloat*, kMaxChannels\u003e channel pointer mapping. This is to\n\u003e prevent a crash in Clang\u0027s -Wunsafe-buffer-usage pass due to passing in\n\u003e an incomplete type.\n\u003e\n\u003e This change defers a call to dumps.erase(dumps.begin()) in\n\u003e minidump_uploader.cc until after attachment file cleanup. Previously,\n\u003e the erase call freed the DumpInfo instance before iterating over\n\u003e that instance\u0027s attachments, which caused a UaF that this recent roll\n\u003e surfaced.\n\u003e\n\u003e 2026-07-20 phosek@google.com [libcxx][NFC] Address -Wmicrosoft-cast in MSVC\u0027s exception_ptr (#210570)\n\u003e 2026-07-19 github.snugness349@passinbox.com [libc++][ranges] Add missing test cases for `[[nodiscard]]` tests in `enumerate_view` (#209289)\n\u003e 2026-07-17 aidengrossman@google.com Revert \"[lit] Delete the external shell\" (#210433)\n\u003e 2026-07-17 aidengrossman@google.com [lit] Delete the external shell (#209571)\n\u003e 2026-07-17 ldionne.2@gmail.com [libc++] Update release runners to the image that was used on main at the branch point (#210378)\n\u003e 2026-07-17 oyzawqgcfc@gmail.com [libcxx] avoid include Uppercase windows headers (#208903)\n\u003e 2026-07-16 nikolasklauser@berlin.de [libc++] Optimize std::is_heap_until (#209141)\n\u003e 2026-07-16 phosek@google.com [libc++] Partially revert #208330 (#209928)\n\u003e 2026-07-15 paulkirth@google.com [libcxx] Mark test unsupported in clang-24 (#209794)\n\u003e 2026-07-15 ldionne.2@gmail.com [libc++] Treat negative counts in copy_n \u0026 friends as no-ops (#207086)\n\u003e 2026-07-15 ldionne.2@gmail.com [libc++] Add benchmarks for std::binary_search and std::equal_range (#207268)\n\u003e 2026-07-15 ldionne.2@gmail.com [libc++] Add benchmarks for std::replace_copy and std::replace_copy_if (#207070)\n\u003e 2026-07-15 michaelrj@google.com [libcxx][libc] update LLVM-libc test status (#201236)\n\u003e 2026-07-15 ldionne.2@gmail.com [libc++] Create libc++ 24 release notes (#208814)\n\u003e 2026-07-14 efriedma@qti.qualcomm.com Make ios_base::xalloc non-atomic with LIBCXX_ENABLE_THREADS\u003dOFF.
