You (and a lot of people) make it sound like its magic but it's not - http://blog.stuffedcow.net/2014/01/x86-memory-disambiguation/ http://blog.stuffedcow.net/2

- DannyBee 12y agoIt's not magic. But it's not what that blog post is talking about. On some of these processors, 128 bytes of stack or so is not really "memory" (in the sense of being stored with memory), so spilling is not that bad.
- brigade 12y agoThat's the magic I'm talking about because it's not true; memory is memory and stack memory isn't treated specially by the processor. What it does have is a store buffer, which applies to all memory accesses and is what store forwarding uses to bypass L1.
- DannyBee 12y agoI'm simply going to disagree with you on this one, because i can't make my evidence public :)
