amakc11 updated this revision to Diff 184496.
amakc11 added a comment.
`// UNSUPPORTED: libcpp-no-exceptions` added. I ran the new test against libc++ in c++98 and c++03 modes once again to make sure it passes. It means that `// UNSUPPORTED: c++98, c++03;` is not needed for the reason I mentioned in my previous comment.
