We must be compatible with the sum of the most restrictive elements of the supporting allocator's build system. Current targets for GWP-ASan include Scudo (on Linux and Fuchsia), and bionic (on Android).2. Scudo specifies `-nostdlib++ -nonodefaultlibs`, meaning we can't use `std::mutex` or `mtx_t`.3. We can't use `sanitizer_common`'s mutex, as the supporting allocators cannot afford the extra maintenance (Android, Fuchsia) and code size (Fuchsia) overheads that this would incur.In future, we would like to implement a shared base mutex for GWP-ASan, Scudo and sanitizer_common. This will likely happen when both GWP-ASan and Scudo standalone are not in the development phase, at which point they will have stable requirements.Reviewers: vlad.tsyrklevich, morehouse, jfbReviewed By: morehouseSubscribers: dexonsmith, srhines, cfe-commits, kubamracek, mgorny, cryptoad, jfb, #sanitizers, llvm-commits, vitalybuka, eugenisTags: #sanitizers, #llvm, #clangDifferential Revision: https://reviews.llvm.org/D61923llvm-svn: 362138 List of files: /llvm-project-15.0.7/compiler-rt/lib/gwp_asan/platform_specific/mutex_posix.cpp Thu, 30 May 2019 19:45:32 +0000 Mitch Phillips <mitchphillips@outlook.com>
