Tue, 14 Jan 2025 15:30:30 +0000

[libc++] Fix ambiguity due to non-uglified member typedefs (#121664)This PR fixes the ambiguities in name lookup caused by non-standard member typedefs `size_type` and `difference_type` in `std::bitset`. Follows up #121620. Closes #121618. List of files: /llvm-project/libcxx/include/__bit_reference

e2c2ffbe7a1b5d9e32a2ce64279475b50c4cba5b - [libc++][NFC] Run clang-format on libcxx/include again (#95874)

Tue, 18 Jun 2024 13:13:45 +0000

[libc++][NFC] Run clang-format on libcxx/include again (#95874)As time went by, a few files have become mis-formatted w.r.t. clang-format. This was made worse by the fact that formatting was not being enforced in extensionless headers. This commit simply brings all of libcxx/include in-line with clang-format again. We might have to do this from time to time as we update our clang-format version, but frankly this is really low effort now that we've formatted everything once.

1ec252298925de50b27930c557ba9de3cc397afe - [libc++] Rename __bit_reference template parameter to avoid conflict (#80661)

Mon, 05 Feb 2024 16:41:12 +0000

[libc++] Rename __bit_reference template parameter to avoid conflict (#80661)As of 4d20cfcf4eb08217ed37c4d4c38dc395d7a66d26, `__bit_reference` contains a template `__fill_n` with a bool `_FillValue` parameter. Unfortunately there is a relatively widely used piece of scientific software called NetCDF, which exposes a (C) macro `_FillValue` in its public headers. When building the NetCDF C++ bindings, this quickly leads to compilation errors when the macro interferes with the template in `__bit_reference`. Rename the parameter to `_FillVal` to avoid the conflict. List of files: /llvm-project/libcxx/include/__bit_reference

Thu, 27 Jul 2023 21:54:59 +0000

[libc++] Simplify single-iterator __bit_iterator algorithm specializationsThe single-iterator algorithms have an implementation for `false` and `true`, which are almost identical. Instead of writing two functions, this refactors the code to take the value searched for as a template parameter. This avoids a lot of code duplication and makes it easier to reason about the algorithm and their difference.Reviewed By: #libc, MordanteSpies: Mordante, libcxx-commitsDifferential Revision: https://reviews.llvm.org/D156033 List of files: /llvm-project/libcxx/include/__bit_reference
