+Compiler Support
+================
+
+As of now only ``Clang`` is fully supported.
+
+We are in the process of supporting ``GCC`` but some memory function implementations rely on `compiler intrinsics`__ that are not currently available in ``GCC``.
+As such we cannot guarantee optimal performance for these functions.
