[libcxx-commits] [PATCH] D80376: [libc++] [P1208] [C++20] Adopt source location from Library Fundamentals V3 for C++20.

[Marek Kurdej via Phabricator via libcxx-commits]

curdeius added a comment.

Ok, so clang 8 doesn't support `consteval`. It also doesn't have required builtins (`__builtin_FILE` etc.). `consteval` works ok on clang 9+.
How can I mark tests as unsupported when the builtins are not supported? (a good example would be column.pass.cpp test that I disabled for gcc that doesn't have `__builtin_COLUMN`)
