> 2019-06-11 mclow.lists Mark CTAD fail tests for set/multiset as XFAIL for older compilers that give different error messages
> 2019-06-11 mclow.lists XFAIL a couple of tests on apple-clang-9.1, which is a compiler that I didn't know existed
> 2019-06-11 eric Check in test that demonstrates ABI break for std::function.

> 2019-06-11 ldionne [libcxx] Slightly improved policy for handling experimental features
> 2019-06-11 mclow.lists Add a test for is_base_of and incomplete types. Because this trait uses a compiler intrinsic which was broken in many clangs, have lots of XFAILs.
> 2019-06-11 mclow.lists XFAIL a couple of CTAD tests on clang-6; it gives different error messages than clang 7/8/9
> 2019-06-10 mclow.lists Recommit r362649, which was reverted in r262680 because of bugs in std::to_chars (which have now been fixed). Speedup to_string and to_wstring for integers using stack buffer and SSO

> 2019-06-04 mclow.lists We had a _LIBCPP_ASSERT commented out because gcc 4.9 didn't like it. We (LLVM) now require GCC 5.1, so that's not a problem any more. Re-enable the assertion. Fixes PR#36863
