<p>
The <code>PCALIGN</code> pseudo-instruction is used to indicate that the next instruction should be aligned
to a specified boundary by padding with no-op instructions.
</p>

<p>
It is currently supported on arm64, amd64, ppc64, loong64 and riscv64.

For example, the start of the <code>MOVD</code> instruction below is aligned to 32 bytes:
<pre>
PCALIGN $32

pkg regexp/syntax, const OpAlternate Op
pkg regexp/syntax, const OpAnyChar Op
pkg regexp/syntax, const OpAnyCharNotNL Op
pkg regexp/syntax, const OpBeginLine Op
pkg regexp/syntax, const OpBeginText Op
pkg regexp/syntax, const OpCapture Op
pkg regexp/syntax, const OpCharClass Op
pkg regexp/syntax, const OpConcat Op
pkg regexp/syntax, const OpEmptyMatch Op
pkg regexp/syntax, const OpEndLine Op

</pre>

<p>
An <i>assignment operation</i> <code>x</code> <i>op</i><code>=</code>
<code>y</code> where <i>op</i> is a binary <a href="#Arithmetic_operators">arithmetic operator</a>
is equivalent to <code>x</code> <code>=</code> <code>x</code> <i>op</i>
<code>(y)</code> but evaluates <code>x</code>
only once.  The <i>op</i><code>=</code> construct is a single token.
