Bumping to gcc10 rather than gcc9 would have the benefit that we could get a work-alike for C++20 `std::is_constant_evaluated` even though we're not otherwise using C++20. Sufficiently recent versions of all of our supported compilers provide `__builtin_is_constant_evaluated`. That first shows up in gcc10. We're already requiring versions of clang and msvc that provide it. There are a bunch of potential improvements we could make by having such a work-alike. ------------- PR Comment: https://git.openjdk.org/jdk/pull/14988#issuecomment-1895511862
