Allow chrono::hh_mm_ss to be constructed from unsigned durations (#209686)\n\n**_Implementation details_**:\n- Use `is_unsigned_v` instead of `numeric_limits\u003cRep\u003e::is_signed`, which\nis used by `chrono::abs`. `numeric_limits\u003cRep\u003e::is_signed` may return\nfalse when a custom `Rep` does not specialize `numeric_limits`. Relying\non it to detect the unsigned case could therefore be unreliable for such\na type. `is_unsigned_v` instead gives a compile-time path for built-in\nunsigned types, while the sign check keeps signed types correct.\n\n- The constructor calls `__abs_d` four times because each member is\ninitialized separately. This should not affect runtime performance\nbecause the compiler should inline `__abs_d` and eliminate the repeated\ncalculations. We could use another helper function or helper class to\nexplicitly compute the absolute duration only once. However, this would\nadd extra glue code, and the added complexity is not worthwhile I think.\n\n---------\n\nCo-authored-by: A.

They were handling the compiler in different ways: some\nscripts would just run the libc++ build (or test suite configuration)\nwithout specifying the compiler, which means the $CXX environment\nvariable was used if present. Other scripts (e.g. run-benchmarks) would\naccept the compiler as an argument, but would fail to pass it down when\nconfiguring the test suite, which led to issues.\n\nThis patch passes the compiler explicitly in all scripts: this removes\nany potential confusion around how the compiler should be specified (env\nvar or argument). The only exception is build-at-commit, where the\ncompiler is still specified by passing the appropriate CMake arguments.\nThe reason for this exception is that passing arguments to CMake is\nactually the way we want to configure aspects of the build (and the test\nsuite) in the long term, it\u0027s just that the test suite doesn\u0027t support\nthis cleanly due to the CMake/Lit split at the

The general idea is\nthat if 0% falls within the confidence interval, we can\u0027t really be\ncertain that the result changed at all. Similarly, if significant\nnegative and positive % diffs are in the confidence interval, we can\u0027t\nbe confident that we are introducing an optimization, regression, or any\nchange at all.\n\nI think this approach is reasonable given the small number of samples\n(usually around 3), which severely limits the statistical methods\navailable to us.\n\nAssisted by Claude\n\nGitOrigin-RevId: d9f6dbca81714fd5ee1c5aaf656fed6b0b5a4c01\n" }, { "commit": "c64207e25898db032ef5922d46e77321864e93a8", "tree": "c8f0e27724b8438a73b440cfe91a058cdeb40954", "parents": [ "e493de2fd4022a09653a750e03ae91001a710c3e" ], "author": { "name": "Liza Burakova", "email": "liza@chromium.org", "time": "Tue Jul 14 14:26:11 2026 -0400" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Jul 14 11:30:33 2026 -0700" }, "message": "[libc++][pstl] Add missing #pragma GCC system_header to libdispatch.h (#209579)\n\nThis adds `#pragma GCC system_header` to libdispatch.h, as removing the\n`[system]` attributes in the modulemap surfaced this gap.\n\nGitOrigin-RevId: 3e706075dc1857e88a293b8104c81b31a08f4cd5\n" }, { "commit": "e493de2fd4022a09653a750e03ae91001a710c3e", "tree": "fdf3d40c851570ad5e9b2123035eb0d82720ee92", "parents": [ "ec23107b7b98ec2af6d85a2f00c54606c6e3d553" ], "author": { "name": "Felipe de Azevedo Piovezan", "email": "fpiovezan@apple.com", "time": "Tue Jul 14 18:12:19 2026 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Jul 14 10:15:52 2026 -0700" }, "message": "Revert \"[libc++][NFC] Inline std::function members into the class body\" (#209555)\n\nReverts llvm/llvm-project#209461\n\nThis is breaking LLDB testing bots and it also failed pre-merge CI.\n\nGitOrigin-RevId: 7618426138aae95561da676a1d1e10ee0392bf78\n" }, { "commit": "ec23107b7b98ec2af6d85a2f00c54606c6e3d553", "tree": "ce2fd1494a45f48fe1557615639db5391ced4c68", "parents": [ "7af2b16b3a8e1388b046765e1a52aaf5b7059e88" ], "author": { "name": "Hristo Hristov", "email": "hghristov.rmm@gmail.com", "time": "Tue Jul 14 20:07:48 2026 +0300" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Jul 14 10:10:25 2026 -0700" }, "message": "[libc++][ranges][NFC] Format `view.interface.pass.cpp` (#209391)\n\nA prerequisite to #205012\n\nGitOrigin-RevId: 9c7d1d2fe0d607b0cd5cfca1b8bb9ea6eee374ec\n" } ], "next": "7af2b16b3a8e1388b046765e1a52aaf5b7059e88" }
