(for example, <code>go build -ldflags "-s" prog.go</code>).

<p>

The code generated by the <code>gc</code> compiler includes inlining of
|
||||
function invocations and registerization of variables. These optimizations
|
||||
can sometimes make debugging with <code>gdb</code> harder. To disable them
|
||||
when debugging, pass the flags <code>-gcflags "-N -l"</code> to the

<a href="/cmd/go"><code>go</code></a> command used to build the code being
