Drawn in by the Emacs, learnt something new about C and C++, thank you for this! Very readable article for someone who doesn't feel too confident with low-level bits. Btw, is this representation the reason why OCaml's ints are not as big as C ints? Also interesting that the Haskell pointer tagging you link to[0] was done the way it was to avoid CPU branch misprediction, and that the old way which it replaced was "the source of half of the branch misprediction events". I wonder how "branch prediction friendly" current Haskell is. [0] https://simonmar.github.io/bib/papers/ptr-tagging.pdf |
