Link: https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket/8665412825518147009/+/u/compile/raw_io.output_text_failure_summary_\n\nOriginal change\u0027s description:\n\u003e Roll libc++ from d816ed0274ed to 64f64c14ae2f (284 revisions)\n\u003e\n\u003e https://chromium.googlesource.com/external/github.com/llvm/llvm-project/libcxx.git/+log/d816ed0274ed..64f64c14ae2f\n\u003e\n\u003e - Removes obsolete `_LIBCPP_NO_ABI_TAG` from `buildtools/third_party/libc++/__config_site` to match `_LibcxxExplicitABIAnnotations` pragma behavior and avoid `abi_tag` redeclaration conflicts in `\u003c__locale_dir/support/windows.h\u003e` (#222081).\n\u003e - Adds `//third_party/libc++/src/src/debugging.cpp` to `buildtools/third_party/libc++/BUILD.gn` for C++26 `\u003cdebugging\u003e` (#81447) and removes `-Wundef` in `buildtools/third_party/libc++/BUILD.gn` (#236806).\n\u003e - Adds missing `\u003ccstddef\u003e` / `std::size_t` in `base/allocator/partition_allocator/src/partition_alloc/internal_allocator_forward.h`, `base/containers/to_vector.h`, and `base/numerics/basic_ops_impl.h` after `\u003cnew\u003e` stopped transitively including `\u003ccstddef\u003e` (#222814).\n\u003e - Binds `network::kFencedFrameAllowedFeatures` to a local `base::span` in `services/network/public/cpp/permissions_policy/permissions_policy.cc` to avoid `-Wunreachable-code` when `kFencedFrameAllowedFeatures` is an empty `constexpr base::span` (#213752).\n\u003e\n\u003e 2026-11-03 anant1234466@gmail.com [libc++] Implement LWG4294: bitset(const
