1This is meant to be a general place to list things that should be done "someday" 2 3ABI Related Tasks 4================= 5* Explicitly manage and verify symbols exported from the dylib. 6* Explore using namespaces for managing symbol visibility. 7* Introduce and document ABI versioning/evolution policy. 8 9CXX Runtime Library Tasks 10========================= 11* Cleanup #ifdef hell in sources files that supports the different ABI libraries. 12* Fix that CMake always link to /usr/lib/libc++abi.dylib on OS X. 13* Fix selection of ABI symbol list on OS X. 14* Have CMake generate linker scripts for libc++.so that it properly links the 15 runtime library. 16* Look into mirroring libsupc++'s typeinfo vtable layout when libsupc++/libstdc++ 17 is used as the runtime library. 18* Audit libraries that CMake links into libc++. Are they all required? 19* Investigate and document interoperability between libc++ and libstdc++ on 20 linux. Do this for every supported c++ runtime library. 21 22Atomic Related Tasks 23==================== 24* Support <atomic> in C++03 (needed for internal use). 25* Audit use of libatomic builtins in <atomic> with GCC. 26* future should use <atomic> for synchronization. 27* call_once should use <atomic> for synchronization. 28* Audit shared_ptr use of <atomic> 29 30Test Suite Tasks 31================ 32* Get test suite passing in C++03. 33* Move all libc++ specific tests from test/std into test/libcxx. 34* Improve how LIT handles compiler warnings. 35* Improve the quality and portability of the locale test data. 36 37Misc Tasks 38========== 39* Find all sequences of >2 underscores and eradicate them. 40* run clang-tidy on libc++ 41* Document the "conditionally-supported" bits of libc++ 42* Look at basic_string's move assignment operator, re LWG 2063 and POCMA 43* libc++ is missing try_emplace 44* Put a static_assert in std::allocator to deny const/volatile types (LWG 2447) 45* Investigate the effect of using __decltype instead of __typeof__ to provide 46 decltype in C++03. What code could be broken by this change? 47* Convert failure tests to use Clang Verify. 48* Document support (or lack of) for C++11 libraries in C++03. 49* Document supported compilers. 50
