* NEW: Work on JIT continues... * NEW: Better panic errors. [INTERPRETER] * NEW: Remove the old JIT stuff. * NEW: Calls gb.jit at runtime if needed. If a fast function has no jit implementation, the bytecode version is used. * NEW: Start defining the JIT interface needed by the JIT functions. * NEW: The common static character buffer is now twice the size of the maximum symbol length, to avoid possible overflows. [GB.JIT] * NEW: Compilation starts to work. * NEW: Debugging messages.
