Any coder who has written an SPU job before knows the problems of trying to access global PPU variables from the SPU. Offload provides a much simpler mechanism for accessing PPU globals.

#include <liboffload>
#include <RendererDebug.h>
extern RendererDebugState gDbgRenderer;
int global = 42;

static void func()
{
	__blockingoffload()
	{
		int local = global; // local has the value 42!
		if (gDbgRenderer.drawState)
		{
			Renderer::DrawLine(....);
			//.....
		}
	};
}

Any global variables that the Offload compiler can see can be linked against, including extern variables defined in other translation units.
