Since `std::exchange`\nis a C++14 feature, we\u0027ll need to use `__exchange` for anything that\u0027s\nfrom C++11.\n\nThis commit also applies `std::__exchange` to a some trivial use-cases\nto show its utility. Applying this project-wide requires a census over\nall of our types. It\u0027s hoped that this will start a community-wide\nclean-up that happens over time.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 8af8a60d544afaeac4834bb78f6b55bc890fb5fd\n" }, { "commit": "788efb4e170b07f6f25a6d39d09bcc0b8aa580f6", "tree": "0cc183dda5f4e33e037b1727ca33bc073157f72e", "parents": [ "ccb5ac2ac7f340a3cc0fb42069a9228cb3e927d7" ], "author": { "name": "Nikolas Klauser", "email": "nikolasklauser@berlin.de", "time": "Mon May 04 06:28:45 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon May 04 06:31:39 2026" }, "message": "[libc++] Remove libc++\u0027s own fenv.h (#194629)\n\nOur own `fenv.h` only `#undef`s macros which the C header might define.\nNone of the libcs we support define any of these functions as macros, so\nwe can simply drop the header.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: f7329e61ad4b0cc069b437ddb15ecd23e65b207b\n" }, { "commit": "ccb5ac2ac7f340a3cc0fb42069a9228cb3e927d7", "tree": "6a6e66d48aaa1dd3858206c80fff073f9b7aefce", "parents": [ "9e387291c5ce91a7f0a672c267e0533f1182fb89" ], "author": { "name": "Nikolas Klauser", "email": "nikolasklauser@berlin.de", "time": "Mon May 04 06:28:24 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon May 04 06:31:17 2026" }, "message": "[libc++] Remove libc++\u0027s own ctype.h (#194615)\n\nOur own `ctype.h` only `#undef`s macros which the C header might define.\nNone of the libcs we support define any of these functions as macros, so\nwe can simply drop the header.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: be8e0842a103e3dfa276572dd4e4d798759e7e4d\n" }, { "commit": "9e387291c5ce91a7f0a672c267e0533f1182fb89", "tree": "0256cefcdde41b7eea700f965cb3024d00376840", "parents": [ "9bf3840218c864e98e98daba55deb22fc11c543a" ], "author": { "name": "Nikolas Klauser", "email": "nikolasklauser@berlin.de", "time": "Mon May 04 06:27:48 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon May 04 06:30:58 2026" }, "message": "[libc++] Simplify more \u003crandom\u003e engines (#195504)\n\nThis uses `if _LIBCPP_CONSTEXPR` to simplify and deduplicate some of the\ncode for the random engines.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: d38d8c6226fad08e38655624a0f2296a1aeea695\n" }, { "commit": "9bf3840218c864e98e98daba55deb22fc11c543a", "tree": "462ee4980f00d35b9e4e6f373a889e7bb7d3e26f", "parents": [ "adfd0cbad5c313b1d292a1f83999524069b14f50" ], "author": { "name": "Connector Switch", "email": "c8ef@outlook.com", "time": "Mon May 04 01:10:08 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon May 04 01:15:48 2026" }, "message": "[libc++] Implement `ranges::fold_right` (#193997)\n\n- Part of https://github.com/llvm/llvm-project/issues/105208.\n- Closes https://github.com/llvm/llvm-project/issues/174060.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 0b652339a5842e2523c274102b95544eb3610bfb\n" }, { "commit": "adfd0cbad5c313b1d292a1f83999524069b14f50", "tree": "484962da34303b7af623d52e1d69495acbc2f913", "parents": [ "b617630cefa3df8f8a4d07450913f2d8afb5b107" ], "author": { "name": "Nikolas Klauser", "email": "nikolasklauser@berlin.de", "time": "Sat May 02 15:06:17 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat May 02 15:10:54 2026" }, "message": "[libc++] Make __is_seed_sequence a variable template (#195420)\n\nThis makes things a bit more readable and improves compile times a bit.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 7d925b9fafe794cdce21ad19a50c8ad13f2fbc76\n" }, { "commit": "b617630cefa3df8f8a4d07450913f2d8afb5b107", "tree": "e1b971fa6d86c8062a05cf1d85ea0be37905e0f3", "parents": [ "2de9f3db23919c023e5c303415326302db74f89f" ], "author": { "name": "Sharjeel Khan", "email": "sharjeelkhan@google.com", "time": "Sat May 02 05:51:46 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat May 02 05:55:46 2026" }, "message": "Update Android CI and Emulator image to API 23 (#194936)\n\nAs seen in https://github.com/android/ndk/issues/2188, NDK will raise\nminimum supported version to API 23 (Android 6.0) in r31.
