C++ (Cpp) jmpdefer Examples

Example #1

File: panic.c Project: eggfly/go-linux-arm

void
runtime·deferreturn(uintptr arg0)
{
	Defer *d;
	byte *argp;
	FuncVal *fn;

	d = g->defer;
	if(d == nil)
		return;
	argp = (byte*)&arg0;
	if(d->argp != argp)
		return;

	// Moving arguments around.
	// Do not allow preemption here, because the garbage collector
	// won't know the form of the arguments until the jmpdefer can
	// flip the PC over to fn.
	m->locks++;
	runtime·memmove(argp, d->args, d->siz);
	fn = d->fn;
	g->defer = d->link;
	freedefer(d);
	m->locks--;
	if(m->locks == 0 && g->preempt)
		g->stackguard0 = StackPreempt;
	runtime·jmpdefer(fn, argp);
}

Example #2

		return;
	argp = (byte*)&arg0;
	if(d->argp != argp)
		return;
	runtime·mcpy(argp, d->args, d->siz);
	g->defer = d->link;
	fn = d->fn;
	runtime·free(d);
	runtime·jmpdefer(fn, argp);
}
