Modified Files: src/external/gpl3/gcc/dist/libstdc++-v3/include/std: mutex src/external/gpl3/gcc/dist/libstdc++-v3/src/c++11: mutex.cc Log Message: Add a walkaround for TLS bug in libstdc++ exposed with std::call_once Currently std::call_once with libstdc++ works only with static linking. Disable code path using __thread types and introduce FIXME_PR_51139. Problem discussed in PR 51139 Functional std::call_once is required in LLVM and LLDB codebase. Example code to test std::call_once: #include <iostream> #include <thread> #include <mutex> #include <cstdlib> std::once_flag flag; int main(int argc, char **argv) { std::call_once(flag, [](){ std::cout << "Simple example: called once\n"; }); return EXIT_SUCCESS; } Sponsored by <The NetBSD Foundation> To generate a diff of this commit: cvs rdiff -u -r1.1.1.4 -r1.2 \ src/external/gpl3/gcc/dist/libstdc++-v3/include/std/mutex cvs rdiff -u -r1.1.1.2 -r1.2 \ src/external/gpl3/gcc/dist/libstdc++-v3/src/c++11/mutex.cc Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
