Author: Mark H Weaver <address@hidden>
Date:   Thu Jan 9 00:10:04 2014 -0500

    PRELIMINARY print.c: Add support for SRFI-38 datum label notation.

commit 6b0a4c2055b55c59c26545e69fc53c41aa478d68
Author: Mark H Weaver <address@hidden>
Date:   Wed Jan 8 23:45:45 2014 -0500

    Add support for cyclic literal data in compiler.
    
    * libguile/vm-i-scheme.c (array-contents): New VM instruction.
    
    * module/language/glil/compile-assembly.scm (vhash-fold-right3,
      fold3, fold2-3): New procedures.
      (add-to-store): Accept new argument 'ancestors'.  Use it to prevent
      infinite loops.  Augment it when traversing into lists, pairs,
      vectors, or arrays.
      (build-constant-store): Adapt to new argument to 'add-to-store'.
      (ref-or-dump): Accept new arguments 'post' and 'f'.  If the referenced
      object has not yet been serialized, augment 'post' to add code that will
      mutate it to the correct value after all initializations.
      (dump1): Accept new argument 'post'.  Return a third value: the new
      'post'.  Pass new arguments to 'ref-or-dump'.
      (dump-constants): Adapt to new argument and return value of 'dump1'.
      Apply post-procs to mutate fields of constants as needed to handle
      cyclic data.
