This is meant to be a general place to list things that should be done "someday" ABI Related Tasks ================= * Explicitly manage and verify symbols exported from the dylib. * Explore using namespaces for managing symbol visibility. * Introduce and document ABI versioning/evolution policy. CXX Runtime Library Tasks ========================= * Cleanup #ifdef hell in sources files that supports the different ABI libraries. * Fix that CMake always link to /usr/lib/libc++abi.dylib on OS X. * Fix selection of ABI symbol list on OS X. * Have CMake generate linker scripts for libc++.so that it properly links the runtime library. * Look into mirroring libsupc++'s typeinfo vtable layout when libsupc++/libstdc++ is used as the runtime library. * Audit libraries that CMake links into libc++. Are they all required? * Investigate and document interoperability between libc++ and libstdc++ on linux. Do this for every supported c++ runtime library. Atomic Related Tasks ==================== * Support <atomic> in C++03 (needed for internal use). * Audit use of libatomic builtins in <atomic> with GCC. * future should use <atomic> for synchronization. * call_once should use <atomic> for synchronization. * Audit shared_ptr use of <atomic> Test Suite Tasks ================ * Get test suite passing in C++03. * Move all libc++ specific tests from test/std into test/libcxx. * Improve how LIT handles compiler warnings. * Improve the quality and portability of the locale test data. Misc Tasks ========== * Find all sequences of >2 underscores and eradicate them. * run clang-tidy on libc++ * Document the "conditionally-supported" bits of libc++ * Look at basic_string's move assignment operator, re LWG 2063 and POCMA * libc++ is missing try_emplace * Put a static_assert in std::allocator to deny const/volatile types (LWG 2447) * Investigate the effect of using __decltype instead of __typeof__ to provide decltype in C++03. What code could be broken by this change? * Convert failure tests to use Clang Verify. * Document support (or lack of) for C++11 libraries in C++03. * Document supported compilers.
