encoding of the machine instructions.
The <code>cmd/internal/obj</code> package takes care of that detail.

<p>
The instructions for both the 386 and AMD64 architectures are listed in
<code>cmd/internal/obj/x86/a.out.go</code>.

<p>
The architectures share syntax for common addressing modes such as
<code>(R1)</code> (register indirect),
<code>4(R1)</code> (register indirect with offset), and

references and resolved names and writes them into a new file
_cgo_import.go, which looks like:
