STL_MSFT created this revision.
[libcxx] [test] Avoid P0138R2, direct-list-init of fixed enums from integers.
This C++17 Core Language feature isn't necessary when testing std::byte.
It's a minor convenience, but it limits test coverage to very new compilers.
(I encountered this because C1XX currently has a bug in this feature, and our
Clang/C2 is still 3.8 and missing this feature. But these tests had UNSUPPORTED
comments knocking out several versions of Clang, so the impact isn't just
limited to us.)
