For example, a compiler must not invert the conditional in this program:
</p>

<pre>
*p = 1
if cond {
	*p = 2
}
</pre>

<p>
That is, the compiler must not rewrite the program into this one:
</p>

<pre>
*p = 2
if !cond {
	*p = 1
}
</pre>

<p>
If <code>cond</code> is false and another goroutine is reading <code>*p</code>,

Slice expressions construct a substring or slice from a string, array, pointer
to array, or slice. There are two variants: a simple form that specifies a low
and high bound, and a full form that also specifies a bound on the capacity.

<h4>Simple slice expressions</h4>

For a string, array, pointer to array, or slice <code>a</code>, the primary expression

<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

bound type parameter:
</p>

<pre>
	P<sub>k</sub> ➞ A<sub>k</sub>
</pre>

<p>
A type argument <code>A<sub>k</sub></code> may be a composite type,
containing other bound type parameters <code>P<sub>k</sub></code> as element types
(or even be just another bound type parameter).
In a process of repeated simplification, the bound type parameters in each type
