I'd like to fix this but I don't know what to do.
I will work on later. Please let me know if you have any solutions.

+The argument to the `asm` macro is not well-formed.
+
+Erroneous code example:
+
+```compile_fail,E0660
+asm!("nop" "nop");
+```
+
+Considering that this would be a long explanation, we instead recommend you to
+take a look at the unstable book:
+https://doc.rust-lang.org/unstable-book/language-features/asm.html
+"##,
+
+E0661: r##"
+An invalid syntax was passed to the second argument of an `asm` macro line.
+
+Erroneous code example:
+
+```compile_fail,E0661
+let a;
+asm!("nop" : "r"(a));
+```
+
+Considering that this would be a long explanation, we instead recommend you to
+take a look at the unstable book:

+"##,
+
+E0662: r##"
+An invalid input operand constraint was passed to the `asm` macro (third line).
+
+Erroneous code example:
+
+```compile_fail,E0662
+asm!("xor %eax, %eax"
+     :
+     : "=test"("a")
+    );
+```

+A clobber was surrounded by braces in the `asm` macro.
+
+Erroneous code example:
+
+```compile_fail,E0664
+asm!("mov $$0x200, %eax"
+     :
+     :
+     : "{eax}"
+    );

+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
+    }
+}
+```
