       hmm today i will speculatively access privilegied memory, causing an attacker to access it due to strange cache behavior - words dreamed up by the utterly Deranged

       @chjara Superscalar doesn't necessarily mean speculative tho

       @chjara some of them aren't even real instructions. The CPU just translates them into something else.

       @chjara I'd shill the mill (haha) but tfw it's still vaporwarethe hardware itself never speculates, it's up to the compiler to emit parallel computations and then select the result which makes it all deterministic and completely avoids this kind of vulnerability
