2019-03-26 thomasanderson [libc++] Fix return value of snprintf_l() on Windows when buffer is too small
2019-03-26 modocache Revert "[coroutines] Add std::experimental::task<T> type"
2019-03-26 modocache [coroutines] Add std::experimental::task<T> type
2019-03-25 mclow.lists Cleaup of requirements for optional. While researching LWG3196, I realized that optional did not reject 'const in_place_t' like it should. Added a test as well, and a check for arrays (which were already disallowed, but now we get a better error message). Should not affect anyone's code.
2019-03-25 ldionne [libc++][CMake] Allow merging libc++abi.a into libc++ even on Apple platforms
2019-03-22 mclow.lists Fix a minor bug with std::next and prev not and negative numbers. In particular, std::prev cannot require Bidirectional Iterators, because you might 'go back' -1 places, which goes forward. Thanks to Ville and Jonathan for the bug report.
2019-03-22 ldionne [libc++] Update the list of symbols exported from libc++abi for new/delete
2019-03-22 ldionne [libc++] Re-export the sjlj ABI v2 for ARM architectures
2019-03-22 mclow.lists Fix a vector test to not use a local type as a template parameter. This causes a warning on C++03. NFC
2019-03-21 ldionne [libc++] Remove too-stringent XFAILs for file_clock tests
2019-03-21 ldionne [NFC][libc++] Reindent #ifdefs
2019-03-21 ldionne [libc++] Re-document how to use <filesystem> with various versions of libc++
2019-03-21 sbenza Add relational benchmark against a string constant.
2019-03-21 ldionne [libc++] Mark bad_any_cast tests as unsupported when the dylib doesn't support bad_any_cast
