  New Revision: 52949

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=52949

  Log:
    * introduce new ISeq binary format serializer/de-serializer
      and a pre-compilation/runtime loader sample.
      [Feature #11788]
    
    * iseq.c: add new methods:
      * RubyVM::InstructionSequence#to_binary_format(extra_data = nil)
      * RubyVM::InstructionSequence.from_binary_format(binary)
      * RubyVM::InstructionSequence.from_binary_format_extra_data(binary)
    
    * compile.c: implement body of this new feature.
    
    * load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq):
      call RubyVM::InstructionSequence.load_iseq(fname) with
      loading script name if this method is defined.
    
      We can return any ISeq object as a result value.
      Otherwise loading will be continue as usual.
    
      This interface is not matured and is not extensible.
      So that we don't guarantee the future compatibility of this method.
      Basically, you should'nt use this method.
    
    * iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions)
      from iseq.c.
    
    * encoding.c (rb_data_is_encoding), internal.h: added.
    
    * vm_core.h: add several supports for lazy load.
      * add USE_LAZY_LOAD macro to specify enable or disable of
        this feature.
      * add several fields to rb_iseq_t.
      * introduce new macro rb_iseq_check().
    
    * insns.def: some check for lazy loading feature.
    
    * vm_insnhelper.c: ditto.
    
    * proc.c: ditto.
    
    * vm.c: ditto.
    
    * test/lib/iseq_loader_checker.rb: enabled iff suitable
      environment variables are provided.
    
    * test/runner.rb: enable lib/iseq_loader_checker.rb.
    
    * sample/iseq_loader.rb: add sample compiler and loader.
    
        $ ruby sample/iseq_loader.rb [dir]
    
      will compile all ruby scripts in [dir].
      With default setting, this compile creates *.rb.yarb files
      in same directory of target .rb scripts.
    
        $ ruby -r sample/iseq_loader.rb [app]
    
      will run with enable to load compiled binary data.
