Brings libc++ to parity\nwith\nlibstdc++, which has provided richer messages for years.\n\nDiscussed in:\n[RFC](https://discourse.llvm.org/t/rfc-improve-bad-variant-access-what-messages/90716)\n\nAdds an internal derived class of `bad_variant_access` carrying a `const\nchar*`\nmessage, exported from the dylib with availability annotations. The base\n`bad_variant_access` class is unchanged — no ABI flag required, no\nlayout\nchange to the existing type. Throw sites in `__generic_get` and\n`__throw_if_valueless` instantiate the derived type with the appropriate\nliteral; user code catching `bad_variant_access const\u0026` picks up the new\n`what()` via virtual dispatch.\n\nDistinguishes three failure modes:\n- `std::get: wrong alternative for variant`\n- `std::get: variant is valueless`\n- `std::visit: variant is valueless`\n\n## ABI\nUpdated\n`x86_64-unknown-linux-gnu.libcxxabi.v1.stable.exceptions.nonew.abilist`\nbased on a local Linux build.

      "message": "[libc++] std::byteswap support for _BitInt(N) (#196512)\n\nAdd a byte-reversal loop fallback for `std::byteswap` when `sizeof(T) \u003e\n16`,\nso the function works for `_BitInt(N)` with `N \u003e 128` and any future\nwider\ninteger type. Without it, those calls hit `static_assert(sizeof(_Tp) \u003d\u003d\n0)`\nand fail to compile.\n\nReject `_BitInt(N)` where `N` is not a multiple of `CHAR_BIT`. The\nexisting\n`__builtin_bswap{16,32,64,128}` paths swap the storage representation\nincluding padding bits, and the resulting value\u0027s meaning is\nunspecified.\nA new `static_assert` catches that case and reports it. Size-1 types are\nexempt from the check, since no bytes move there.\n\nPart of the [_BitInt(N) libc++\neffort](https://discourse.llvm.org/t/bitint-n-support-in-libc-investigations-possible-improvements-looking-for-guidance/90063).\n\nAssisted-by: Claude (Anthropic)\n\n---------\n\nCo-authored-by: Claude Opus 4.6 \u003cnoreply@anthropic.com\u003e\nGitOrigin-RevId: fdfb99f6336401e534f611c4b2df5a338e26b997\n"

      "message": "[libc++] Add support for thread-id handling for llvm-libc. (#198595)\n\nThis change adds support for properly defining and obtaining\n`__libcpp_thread_id` when llvm-libc is used. It defines the integral\nthread-id (which satisfies necessary restrictions of having total order,\nbeing hashable and formattable) as `pthread_id_np_t` type and uses\n`pthread_getthreadid_np` and `pthread_getunique_np` functions to obtain\nit (added in\nhttps://github.com/llvm/llvm-project/pull/197027, following the\ndiscussions in https://github.com/llvm/llvm-project/pull/195139 and\nhttps://github.com/llvm/llvm-project/pull/195202).\n\nWe also let `_LIBCPP_NULL_THREAD` macro use a more portable\n`PTHREAD_NULL` (defined in the latest POSIX) when this macro is\navailable, so that it would work as expected for opaque `pthread_t`\nimplementations, where default constructor might not necessarily\nzero-initialize all the members.\n\nThis is the last remaining change to allow building libc++ against\nllvm-libc with threads enabled (test-suite results TBD).\n\nGitOrigin-RevId: 493ebf711e3f6641338e153ecdd284f262b4fb65\n"

      "message": "[libc++] Require the exact assignment expression to be trivial in __uninitialized_allocator_copy_impl (#196648)\n\nFixes https://github.com/llvm/llvm-project/issues/196645\n\n`__uninitialized_allocator_copy_impl` has an optimization that replaces\n`allocator_traits::construct` with `std::copy` for raw pointer ranges\nwhen the element type is trivially copy constructible and trivially copy\nassignable.\n\nThe copy-assignment trait only checks whether assignment from `const T\u0026`\nis trivial. That is weaker than the expression used by `std::copy`,\nwhich evaluates `*out \u003d *in`. If overload resolution selects a different\nnon-trivial assignment operator for that expression, `std::copy` can\ncall that operator on uninitialized storage.\n\nCheck `is_trivially_assignable\u003c_Out\u0026, _In\u0026\u003e` instead. This matches the\nassignment expression used by `std::copy`, preserves the optimized path\nwhen that assignment is actually trivial, and avoids making non-const\nraw pointer callers select the generic `allocator_traits::construct`\noverload due to a qualification conversion.\n\nAdd a vector copy-constructor regression test with a type whose\ndefaulted copy assignment is trivial but whose templated assignment\noperator is selected for non-const lvalue sources.\n\nGitOrigin-RevId: 859c550e95bb48a563225a251e8b2f969b32456a\n"
