+Date: Fri, 5 Aug 2022 06:56:05 -0700
+Subject: [PATCH] Map the absl::is_trivially_* functions to their std impl
+
+There's no point redefining these functions if they are supported by the compiler and the version of libstdc++. Also, some of the builtins used by the absl implementation of these functions (e.g. __has_trivial_destructor) have been deprecated in Clang 15.
