<h3 id="directives">Directives</h3>

<p>
The assembler uses various directives to bind text and data to symbol names.
For example, here is a simple complete function definition. The <code>TEXT</code>
directive declares the symbol <code>runtime·profileloop</code> and the instructions
that follow form the body of the function.

      return Reflection.getPackageName(className);
    }

    /**

     *
     * <p>Behaves similarly to {@link Class#getSimpleName()} but does not require the class to be
     * loaded.
     *
     * <p>But note that this class uses heuristics to identify the simple name. See a related

 * <p>Another example is an iterator that skips over null elements in a backing iterator. This could
 * be implemented as:
 *
 * <pre>{@code
 * public static Iterator<String> skipNulls(final Iterator<String> in) {
