+# Two critical steps are required here to get this working:
+#
+# * First, the Rust standard library needs to be compiled. The default version
+#   is not compatible with atomics so we need to compile a version, with xargo,
+#   that is compatible.
+#
+# * Next we need to compile everything with the `atomics` feature enabled,
+#   ensuring that LLVM will generate atomic instructions and such.

+# currently compatible with atomics, so we go with the --no-modules output.
