Shape information allows the linker to check the importing module's compile-time expectation against the run-time value of its imports. The JIT, in turn, can rely on that checking to better inline structure-type predicates, etc., and to more directy call JIT-generated code across module boundaries. In addition to checking the "shape" of an import, the import's JITted vs. non-JITted state must be consistent. To prevent shifts in JIT state, the `eval-jit-enabled' parameter is now restricted in its effect to top-level bindings. |

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. Instructions for building Racket from source are in src/README. License ------- Racket Copyright (c) 2010-2012 PLT Scheme Inc.
