Agner's CPU blog

agner: Neat! Is the throughput of pairs of stack operations (or equivalent mov patterns) still limited by the single store port? I'm wondering whether they support store vectorization of stores to consecutive addresses. Store port certainly has enough bw. This would be an orthogonal but complementar...

Is there evidence that the core can handle stack manipulations (push & pop) and still forward values directly? Given the presence of the stack engine in the front end, I'm sorta expecting the two features to play together nicely.
