  New Revision: 12734

  Modified files:
    trunk/ChangeLog
    trunk/hash.c
    trunk/include/ruby/intern.h
    trunk/insnhelper.ci

  Log:
    * hash.c (rb_hash_lookup): added.  this function is similar to
      rb_hash_aref(), but doesn't call Hash#default when no entry
      exists.
    * include/ruby/intern.h: ditto.
    * insnhelper.ci (lfp_svar_get): use rb_hash_lookup().
