      The execution tracer has been completely overhauled in this release, resolving several long-standing
      issues and paving the way for new use-cases for execution traces.
    </p>
    <p>
      Execution traces now use the operating system's clock on most platforms (Windows excluded) so

look in the source for the <code>obj</code> support library for
that architecture, located in the directory <code>src/cmd/internal/obj/arm</code>.
In that directory is a file <code>a.out.go</code>; it contains
a long list of constants starting with <code>A</code>, like this:
</p>

<pre>
const (
	AAND = obj.ABaseARM + obj.A_ARCHSPECIFIC + iota
	AEOR
	ASUB
	ARSB
	AADD
	...
</pre>
