The JIT and bytecode compiler disagreed on the definition of "constant". Now there are two levels: "constant" means constant across all instantiations, and "fixed" means constant for a given instantation. The JIT uses this distinction to generate direct-primitive calls or not. (Without the distinction, a direct jump to `reverse' could be wrong, because `racket/base' might get instantiated with the JIT disabled or not.) Also, fixed a bug in the JIT's `vector-set!' code in the case that the target vector is a top-/module-level reference that is ready, fixed, or constant. |

The Racket programming language =============================== Important executables: * DrRacket: Racket's integrated development environment (start here!). * Racket: the main command-line entry point for running racket programs and scripts. * GRacket: the GUI-mode Racket executable. * raco: Racket's command-line toolset. More Information ---------------- Racket comes with extensive documentation: use DrRacket's `Help' menu, or run `raco docs'. Also, visit us at http://racket-lang.org/ for more Racket resources.
