It's interesting that the impedence the author was experiencing was one of the CPU incorrectly "speculating" about the intent. We as readers are left to speculate about the problem being solved by the author.
Based on the content of his recent articles, we could assume he is continuing his development of a JIT for a Rust port of his graphics engine. Given that assumption, I would argue that the compiler writers are lagging here--specifically lack of dynamic compilation. For example, is there a JIT compiler for the Rust language? I was thinking about reproducing his experiment in SBCL, which does have dynamic compilation--although it wouldn't be a real "apples" to "apples" comparison because my work machine is a x86_64.
