I'd like to understand more about the type of reordering operations you're
describing, and I assume I'm probably not the only one on the list who'd be
interested. Can you reference any online documentation or articles which
describe how this works? Or, alternatively, supply a more detailed description
It's very counter-intuitive for me to hear about a processor that can apparently
reorder operations to load data referenced off a pointer before it loads the
pointer, if I understand your remarks properly.
