+The argument to the `asm` macro is not well-formed.

+Erroneous code example:

+```compile_fail,E0660
+asm!("nop" "nop");

+An invalid syntax was passed to the second argument of an `asm` macro line.

+```

+A clobber was surrounded by braces in the `asm` macro.

+
+```compile_fail,E0664

+The `Default` trait was derived on an enum.
+
+Erroneous code example:
+
+```compile_fail,E0665
+#[derive(Default)]
+enum Food {
+    Sweet,
+    Salty,
+}
+```
+
+The `Default` cannot be derived on an enum for the simple reason that the
+compiler doesn't know which value to pick by default whereas it can for a
+struct as long as all its fields implement the `Default` trait as well.
+
+If you still want to implement `Default` on your enum, you'll have to do it "by
+hand":
+
+```
+enum Food {
+    Sweet,
+    Salty,
+}
+
+impl Default for Food {
+    fn default() -> Food {
+        Food::Sweet
+    }
+}
+```
